Pesticides are substances used to control or kill unwanted plants and animals. They are typically spread across broad areas but only a small percentage actually reach the intended target, with most reaching other destinations. Certain pesticides like organophosphates and DDT can harm the environment and wildlife by damaging nervous systems or thinning eggshells. While pesticides have been used for thousands of years, some that were originally developed as nerve agents are still in use today, despite safer alternative pest control methods existing.

The document discusses Ontario's cosmetic pesticide ban which took effect in 2009. It bans the use of pesticides for cosmetic purposes on lawns and gardens. There are some exceptions for public works and agricultural uses. The ban divides pesticides into 11 classes, with Class 7 allowing some pesticides but only for non-cosmetic uses. Homeowners now have to use more natural and organic lawn care methods like soil testing, aerating, dethatching, and proper maintenance to keep lawns healthy without cosmetic pesticides. The ban changed how property owners can manage pests and vegetation on their properties.
pesticide-persistence
This document defines persistent pollutants as toxic chemicals that remain in the environment for long periods without breaking down, accumulate in animals through the food chain, and are widespread. It discusses specific persistent organic pollutants like DDT, PCBs, dioxins, and mercury that were widely used but are now regulated or banned due to health effects. The document also outlines integrated pest management as a more sustainable approach than using persistent pesticides.
Pesticides & Health
Pesticides can cause both acute and chronic health effects in humans. Acute pesticide poisoning commonly occurs due to occupational or accidental exposure and can result in death. An estimated 3% of agricultural workers experience an acute pesticide poisoning episode annually. Chronic effects may include neurological impacts, cancer, and disruption of the endocrine system. Data on pesticide-related illnesses and deaths is limited in the UAE and Al Ain.

The document discusses the environmental impacts of pesticides, how pesticides can contaminate soil and water sources like groundwater, and the health effects pesticides can have on humans and non-target organisms through routes of exposure like skin contact, inhalation, and ingestion. It also provides information on emergency responses to pesticide exposure, like first aid measures and contacting poison control centers, as well as the risks of heat stress when applying pesticides in hot conditions. The goals of responsible pesticide use are to achieve effective pest control while minimizing risks to the environment.Effects of pesticides on environment
Pesticides can contaminate the environment through various pathways after application. They can spread through the air via volatilization and wind, polluting nearby areas. Pesticides also pollute water sources through direct spraying, leaching into soil, and runoff. When water becomes contaminated, it can harm aquatic life, reduce drinking water quality, and impact irrigation. Pesticides also pollute soils by affecting microorganisms and decreasing fertility. Long-term pesticide use can lead to bioaccumulation in animals and biomagnification up the food chain. Integrated pest management and careful pesticide selection, application, disposal, and avoidance of heavy rain can help minimize environmental pollution.

Pesticides
This science exhibition presentation summarizes the negative effects of chemical pesticides on the environment. It discusses how pesticides can contaminate air, water, and soil through drift, runoff, and leaching. This pollution impacts ecosystems and public health. Pesticides also reduce biodiversity in soil, harm pollinators, and can cause pests to develop resistance over time. The presentation advocates for alternative pest control methods like integrated pest management that are more environmentally friendly.
Pesticides problems
There are four main problems caused by pesticides: super bugs that have evolved resistance, persistent pesticides that don't break down easily, bioaccumulation of pesticides in tissues up the food chain, and pesticides eliminating both pests and beneficial insects. A better approach is integrated pest management which uses multiple control methods like resistant plant varieties, beneficial insects, microbial pesticides, insect sterilization, biochemical pesticides, cultivation timing, and small amounts of synthetic pesticides to reduce pest populations while minimizing pesticide use. Integrated pest management has seven parts to its program.
Tech media presentation
The document discusses the risks of pesticide use. It notes that pesticides can kill both pests and beneficial organisms, and outlines issues like toxicity, exposure, and lack of long-term testing. Pesticides are linked to health problems in humans and mass die-offs of pollinators like bees, which threaten food supplies if populations collapse. While pesticides are used to increase crop yields, overreliance on chemicals carries environmental and health risks that must be addressed through stronger regulation and alternative pest control methods.
CURRENT PESTICIDE HAZARDS IN AGRICULTURE AND HUMAN HEALTH; APPROACHES OF ORGA...
Pesticides are widely used in agriculture to prevent the destruction of crops by pests like insects, weeds, and diseases. However, pesticides can have negative impacts on human health and the environment. Prolonged or improper exposure to certain pesticides is linked to health issues like cancer, neurological problems, and reproductive disorders. Organic agriculture promotes alternative natural techniques like crop rotation, companion planting, and biological pest control to reduce the need for pesticides. While organic pesticides degrade faster, some can still pose chronic toxicity risks if misused. Making the transition to more sustainable and safer farming practices can benefit both the environment and public health.
Pesticides and Biomagnification
This document discusses pesticides and their environmental impacts. It describes how pesticides are commonly used to control pests that damage crops but can harm non-target species and accumulate up food chains. Some key issues are pesticides polluting soil, air and water; killing beneficial organisms; and reaching toxic levels in top predators through biomagnification. The document also presents alternatives like organic farming that minimize pesticide use through ecological methods, and integrated pest management that employs multiple techniques.
Pesticide impact on human and environment
This document provides an overview of an upcoming seminar on the impact of pesticides on human health and the environment. The seminar will cover topics such as the positive and negative effects of pesticide use, problems associated with pesticide application, and how to minimize harmful impacts. It will explore how pesticides entered agricultural use to increase crop yields but can also contaminate soil, water and air and harm non-target organisms and human health through various exposure routes and health effects both acute and chronic. The seminar aims to educate participants and find a balance in pesticide use and alternative approaches like integrated pest management.
negative impact of pesticide usage in agriculture
Pesticides have negative environmental impacts when used in agriculture. They can pollute soil, air, and water through various routes such as spraying, leaching, runoff, and erosion. This pollution affects both target and non-target organisms. Long-term exposure to pesticides is linked to health issues like cancer and neurological and reproductive problems in humans. Pesticides also harm plants, animals, and beneficial soil microorganisms. Their overuse can result in pest resistance, new pest outbreaks, and biomagnification up the food chain. Strict regulation of pesticides and alternative natural pest control methods are needed to protect the environment and public health.
Impact of Pesticides on Environment
This presentation has been made to make public aware of effects of pesticides on environment. Farmers can be made aware of harmful effects of different categories of insecticides. Students, field workers of agriculture extension program can use this presentation for learning and teaching. Insecticides have benefits but accompanied with harmful effects. So, great care is needed for using any kind of pesticides.
Pesticide
The document discusses the negative impacts of pesticide use. It defines pesticides as poisons used to kill pests that harm plants, animals, or humans. The main reasons pesticides are bad are that they are harmful to human health, contaminate water sources, and some pests they target are not actually harmful. Pesticides can cause various cancers, developmental issues, and acute symptoms. They also negatively impact wildlife and aquatic environments, killing millions of birds and fish each year. The widespread use of pesticides results in millions of pesticide poisonings and deaths among agricultural workers and the general public annually.
Pesticides
This document provides information about pesticides including:
- Pesticides are substances used to kill, repel, or control certain forms of plant or animal life considered pests. They include herbicides, insecticides, fungicides, and others.
- Pesticides have a brief history beginning with organized agriculture when pests threatened food supplies, and are now widely used to support efficient use of resources and high standards of living.
- Pesticides have benefits but also risks, so safer chemicals and application methods are constantly improved through research and education while balancing policies based on facts.
Hazardous Effects of Pesticide Diazinon on Living Organisms
One of the major goals of agriculture is to meet the increasing food demand of the growing population and as a result the use of pesticides enormously increases directly. Pesticides are chemical agents used to kill or control the growth of pests. Pesticides have their major role in agriculture on the other hand it also has negative impact on environment and non target organisms. They are classified on the basis of toxicity, target of pest, chemical composition, mode of action, mode of entry, etc. Most commonly they are classified as insecticides, herbicides, weedicides, and rodenticides. Diazinon is an organophosphorous pesticide majorly used in ornamental plants, lawns, fruits and vegetables to destroy pests and insects. Use of pesticides in agriculture results in higher yield, quality product and economic benefits to the farmers and consumers while uncontrolled use of pesticides leads to their bioaccumulation and magnification in the environment which pose hazardous effects to the human health.

Adverse effects of pesticides in agriculture
Pesticide use in agriculture can have adverse health and environmental effects. Pesticides can harm farmers and agricultural workers through inhalation, ingestion and dermal contact. They also negatively impact domestic animals, beneficial insects, wildlife and aquatic life. Long term effects of pesticide exposure include neurological problems, respiratory illness, dermal issues, reproductive harm and increased cancer risk. Pesticide contamination of water and soil poses ongoing risks to the environment. Widespread pesticide use has also led to resistance in pests and the decline of natural pest predators.
PESTICIDES RESIDUES
Pesticides have been linked to a number of health problems, including neurologic and endocrine (hormone) system disorders, birth defects, cancer, and other diseases.
Pesticide Pollution
pollution due to usage of pesticides on human health and environment alternatives, and effectiveness of alternatives are discussed in this presentation
Pesticides (2)
This document defines pesticides and describes different types of pests including animal pests like rodents and insects, and plant pests like weeds and microorganisms. It discusses how pesticides work by inhibiting metabolic processes and outlines their mechanism of action, potency, onset, and dose. Common pesticide types include insecticides, herbicides, fungicides, and rodenticides. The document also covers pesticide choice based on pest type and habitat, as well as methods of controlling pests including mechanical, biological, environmental, agricultural, and chemical methods. Integrated Pest Management is discussed as an alternative approach.
Pesticide residues in food
This document discusses pesticide residues in food. It begins by defining pesticides and explaining how residues can occur in foods when pesticides are used during agricultural production. It notes that processing foods can help reduce residues. It then discusses groups vulnerable to pesticide effects like children. The document outlines pesticide risk assessment and various health effects of pesticide exposure. It concludes by discussing approaches for preventing and controlling pesticide residues like consumer education, legislation, research into alternatives, and promotion of integrated pest management.
Effects of pesticides on ecosystems
Pesticides have widespread negative effects on ecosystems. Over 98% of insecticides and 95% of herbicides do not reach their intended target, and instead contaminate air, water, soil and non-target species. Pesticide use reduces biodiversity and threatens endangered species. Pesticides bioaccumulate up the food chain and can cause poisoning in livestock, wildlife and pets. While pesticides are intended to control pests, they also have unintended consequences across entire ecosystems. Alternative approaches like manual removal of weeds, using pest traps and lures, and supporting natural biocontrol agents can help control pests while avoiding harmful pesticides.

Classification of pesticides
This document discusses the classification of pesticides. It defines pesticides as substances that control pests like insects, weeds, rodents, etc. that compete with humans for food or spread disease. Pesticides can be classified based on their target pest, mode of action, chemical structure, application method, and timing of use. Common classifications include insecticides, herbicides, fungicides, and others for specific pest types. Pesticides are also grouped based on how they work, such as stomach poisons that kill after ingestion, contact poisons that kill on contact, and systemic poisons that spread throughout a plant. The document also discusses different modes of action like nerve poisons, muscle poisons, and
Pesticide Effects
Pesticides are substances used to control pests like insects, weeds, and fungi. They are classified as insecticides, herbicides, fungicides, and rodenticides. While pesticides provide benefits like controlling diseases and protecting crops, they can also harm the environment and human health if misused. A tragic example is the 1984 Bhopal gas tragedy in India where a leak at a pesticide plant killed thousands. An ideal pesticide would effectively control pests without harming people, wildlife, or the environment.
toxicity-of-pesticides
This document discusses pesticide toxicity and exposure. It explains that toxicity is determined by an pesticide's ability to cause harm, while exposure depends on how the pesticide enters the body through skin, mouth, lungs, or eyes. Common pesticides like organophosphates and carbamates interfere with the nervous system and can cause acute or chronic health effects from both large and small repeated exposures. Proper use of personal protective equipment and understanding pesticide labels is important for minimizing health risks.
Pesticide and their residue effect
This document discusses pesticides and their residues in food. It defines pesticides as substances used to prevent, destroy, repel or attract pests during production, processing, storage, transport or packaging of food. Pesticide residue above maximum residue limits can pose health risks to humans. Several studies in India have found high percentages of vegetable and milk samples contaminated with pesticide residues like DDT and organochlorines. The document outlines various government organizations and regulations related to monitoring, setting limits, and restricting hazardous pesticides to ensure food safety.

ppt of fate of pesticides in environment or environmental polution by pesticides
Nature is blessed with wide range of organisms where it perfectly balances the food chain and the ecosystem. Pseudomonas fluorescens, P. putida and some fungi antagonists are important biocontrol agents used against plant pathogenic bacteria which are known to produce special structures known as siderophores. Siderophores are defined as relatively low molecular weight, ferric ion specific chelating agents elaborated by bacteria and fungi growing under low iron stress (Neilands, 1981). The role of these compounds is to scavenge iron from the environment and to make the mineral. There are three main kinds of Siderophores known as hydroxamate, catecholate and carboxylate. Most organisms require iron as an essential element in a variety of metabolic and informational cellular pathways. In the aerobic environment iron exists mainly as Fe (III) and tends to form insoluble hydroxides and oxyhydroxides, making it largely unavailable to microorganisms. Therefore, they need mechanisms to solubilize Fe (III) to make it available for uptake; these mechanisms usually involve the production of siderophores.
Agriculture & pesticides
The document discusses several topics related to agriculture and pesticide use including:
1) How the "Green Revolution" through the use of specialized crop breeds and technology helped increase global food production to keep pace with population growth.
2) Issues with monocultures and reduced crop diversity that have occurred due to intensified agriculture.
3) Both the benefits of pesticide use such as increasing food supplies, and the problems they can cause including impacting non-target organisms, persistence in the environment, and development of pest resistance.
4) Key aspects of pesticide regulation including required information on labels and EPA oversight of laws and restrictions.
Nano technology in Agriculture
Nanomaterials have potential applications in plant protection and agriculture. They can be engineered to have properties like permeability and biodegradability that increase their affinity to targets like pests and pathogens. Nanopesticides and nanofertilizers allow slow release and targeted delivery of agricultural chemicals, reducing usage amounts. However, some negative effects like toxicity, chemical injuries to plants, and health risks must still be addressed through further research. Overall, nanotechnology shows promise for more effective and sustainable crop protection and production if its risks can be properly managed.
Application of nanotechnology in agriculture
This document discusses the potential applications of nanotechnology in agriculture. It notes that nanotechnology could help address challenges facing agriculture like low crop yields, nutrient deficiencies, and climate change. Some potential applications mentioned include nano-sensors to monitor soil and plant health, nano-fertilizers for slow nutrient release, nano-pesticides and insecticides, and nano-materials to remove soil contaminants. The document provides background on nanotechnology and discusses various types of nano-materials and their properties. It outlines how nanotechnology is being researched and applied in areas like precision farming, food science, crop improvement, and soil remediation to enhance agricultural productivity in a sustainable manner.
Effect of Agrochemicals on Environment
This document discusses the long-term effects of agrochemicals on the environment. It notes that while agrochemicals have increased food production, they have also negatively impacted the soil, water, air, and human health. The overuse of agrochemicals has killed beneficial soil organisms, increased nitrate levels in soil, polluted water sources, contributed to air pollution through pesticide drift, and posed health risks to farmers and rural communities through direct exposure. The ideal pesticide would only impact the target pest and break down harmlessly, but in reality no such chemical exists.

Insecticides.ppt
- Insecticides are pesticides used to kill insects and include ovicides and larvicides that target eggs and larvae. They are used in agriculture, medicine, industry, and households.
- There are several types of insecticides including systemic, contact, natural, plant-incorporated protectants, inorganic, organic, organochlorines, organophosphates, carbamates, pyrethroids, neonicotinoids, ryaniods, insect growth regulators, biological, and antifeedants.
- Insecticides can have environmental effects on non-target species if they drift from the application area or if other animals mistake the insecticides for food.
Black mold rot disease of onion
Black mold rot is a fungal disease of onions caused by Aspergillus niger. It causes discoloration and shriveling of onion bulbs. The disease is transmitted through infected soil or seeds and favors high temperatures and humidity. Management strategies include crop rotation, soil solarization, using resistant varieties, and proper drying and storage of bulbs to reduce moisture levels. Effective control requires an integrated approach combining cultural, chemical and biological methods.

- Factors contributing to insect resistance and potential for resurgence after insecticide use.
What are the Advantages & disadvantages of Natural Pesticides
A Natural pesticide is a substance that disrupts or kills organisms that we consider to be pests such as weeds, damaging insects, or microbes that cause disease. Pesticides that are made by other organisms, usually for their own defense or that comes from a natural source like a mineral or a plant are called natural pesticides. Although this is generally true, not all natural pesticides are always safer or better for the environment than man-made pesticides. Nicotine, for instance, is the highly addictive component of cigarette smoke and a natural pesticide found in tobacco leaves, but it is actually much more toxic than the majority of modern synthetic pesticides.
Pesticides.pptx
Pesticides are chemical or biological substances used to kill pests like insects, weeds, and fungi. They have been used for thousands of years by ancient civilizations. Modern pesticides include insecticides, herbicides, fungicides and others. While pesticides are effective at controlling pests and protecting crops, they can also harm the environment, human and animal health if misused or overused. Common concerns include toxic chemicals affecting other organisms and entering the food chain. Proper use and regulation of pesticides seeks to manage pests while minimizing risks.
PESTICIDES (Lesson plan )
This document discusses pesticides, defining them as substances used to control pests. It outlines several types of pesticides including insecticides, herbicides, mollusicides, nematicides, fungicides, and rodenticides. The document discusses the benefits of pesticides in agriculture and how they help farmers produce more food. It also covers the proper application of pesticides and provides video links demonstrating different pesticide uses in farming. Students are assigned to make their own organic pesticide from local resources.
Biopesticides
Plant extracts and bacteria like Bacillus thuringiensis were among the earliest biopesticides. While biopesticides saw limited use with the rise of chemical pesticides, there are now over 245 registered biopesticide ingredients. Biopesticides are generally less toxic than chemical pesticides and often affect only the target pest. They can be effective in small amounts but require knowledgeable application as part of integrated pest management. Common biopesticides are derived from bacteria, fungi, viruses, protozoa, yeasts, and plants.
PESTCONTROL
This document discusses pest control and management. It defines a pest as a living organism that competes with humans for resources like food and water or spreads disease. There are various types of pests including insects, microbes, weeds, and mollusks. The document outlines different pest control methods such as mechanical, biological, environmental, agricultural, and chemical approaches. It emphasizes the importance of an effective pest control program that excludes pests, removes their food sources, controls them with appropriate methods, and keeps proper procedures and records. Overall, the document promotes reducing pesticide use and exposure through safer pest management practices.
CHEMISTRY INVESTIGATORY PROJECT.pptx
This chemistry investigatory project examines the presence of insecticides and pesticides in fruits and vegetables. An experiment was conducted to test samples of different fruits and vegetables for the presence of nitrogen-containing insecticides. The results found that grapes, tomatoes, and potatoes tested positive, indicating they contain such pesticides. The conclusion discusses the ongoing issues with widespread pesticide use but restrictions and substitutes are the best methods to control pests while reducing environmental hazards.
Ppt for sharing
The document summarizes information about endangered species and the steps governments of four countries - India, USA, UAE, and Ukraine - are taking to protect endangered animals. It discusses endangered animals in each country, including the Bengal tiger in India, monarch butterfly in USA, Arabian leopard in UAE, and Alpine shrew in Ukraine.

Pesticides and their effect on earth
- 2. Introduction • Pesticides are a substance used to control, kill, or repel plants and animals (pests). • Pesticide is a general term. • They are normally spread across an area. • 98% of Insecticides and 95% of Herbicides reach a destination other than the target area. Nicolas Vivas
- 3. • Organophosphates are a type of pesticide that attack the nervous system. • DDT is resposible for eggshell thinning. are responsible for the near extinction of some animals. • Some Organophosphates, like DDT, are still used today. Nicolas Vivas
- 4. History • Humans have used pesticides since before 2000 BC to protect their crops. • Nicotine was once used as an insecticide. • Some believe that Strychnine was used to kill Alexander the Great. • Responsible for 5-10% of Ozone Depletion. • Organophosphates were meant to be chemical warfare agents. Nicolas Vivas
- 5. Solutions • Soil Steaming: Will kill pests and increase health of the soil. • The Use of Trap Crops and Crop Rotation. • Use of Biological Pest Controls. • Sweden has halved the use of pesticides and they have hardly had reduction in crops. • Indonesian farmers have reduced the use of pesticides and have seen a 15% increase in crops. Nicolas Vivas
