Pesticides,type nature and their effect on environment
Pesticides are substances used to control pests like insects, plants and fungi. They are classified based on stability, pest targeted, effect on plants and source. Common types include insecticides, herbicides and fungicides. Chemical pesticides include organophosphates and pyrethroids, while biopesticides use microbes, plant-incorporated toxins or pheromones. Pesticides can persist in the environment and accumulate in organisms, posing toxicity risks. They can contaminate water sources and cause cancer or decrease growth and photosynthesis in other species.
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.
Fate of Pesticides in Environment
The document discusses the fate and transport of pesticides in the environment. It describes how pesticides can be broken down through processes like photodegradation, microbial breakdown, and chemical breakdown. It also explains how pesticides can be transferred in the environment through processes like volatilization, runoff, spray drift, leaching, uptake, and adsorption. It then discusses the use of computer models to simulate the movement and behavior of pesticides in soils, water, and air.
Pesticide analysis
This document provides an overview of pesticide analysis. It begins with an introduction to pesticides and pests. It then covers various methods of pest control and classifications of pesticides based on chemical composition and action. The pesticide cycle involving processes like adsorption, volatilization, and degradation is described. Analytical methods for detecting pesticide residues including multiresidue, single residue, and qualitative/quantitative approaches are summarized. Specific analytical techniques like gas chromatography and determination of chlorides and phosphates are outlined. The document provides essential information on pesticides and their analysis in a student project on the topic.
Environmental alteration of pesticides
Pesticides can have significant environmental impacts by affecting non-target species. Over 98% of insecticides and 95% of herbicides spread across agricultural fields reach areas other than their intended target. Runoff can carry pesticides into aquatic environments and wind can disperse them to other locations. The environmental fate of pesticides is determined by their chemical properties and environmental conditions. Factors like temperature, pH levels, light intensity, and microbial activity influence how pesticides degrade and are transported. Characterizing these degradation processes is important for understanding human and environmental exposure levels over time.
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.
FATE OF PESTICIDES Slideshare.pptx
This presentation highlights how synthetic pesticides affect human, animals and environment directly and indirectly. It also sheds light on what happens when the synthetic pesticides are used and how they get on non target organisms. It is worth noting that they can remain in the soil and water for a relatively long time. As much as possible, we should use them according to the instructions given and only use them when it is necessary. One can also consider other pest control measures like integrated pest management that is much safer.

Fertilizers types By Mr Allah Dad Khan Visiting Professor the University of A...
There are several types of fertilizers that can be used to enrich soil and provide nutrients to plants. Organic fertilizers include materials like manure, compost and bone meal which enrich the soil through nitrogen fixation and release nutrients slowly over time. Inorganic fertilizers are synthetic and release nutrients immediately to address nutrient deficiencies in dying plants. Some fertilizers are designed to release nutrients at specific rates, like time-release fertilizers which provide a steady supply of nutrients over several months. Proper fertilizer selection depends on the individual plant needs and soil conditions.
