Air pollution; presentation by Subrat, Vishal, Ashley.. Project Guide: Dr. Ta...Dr. Tanuja Nautiyal
Air pollution is the introduction of particulates, biological molecules, or other harmful gases into Earth's atmosphere, causing disease, death to humans, damage to other living organisms such as food crops, or the natural or built environment.
Air Pollution- Definition, Types, Causes, Effects, Control Physics Wallah.pdfPhysics Wallah
Air Pollution is the release of gases, particles, biological molecules, etc. into the air that are harmful to human health and the environment.”
What is Air Pollution?
Air Pollution refers to the undesirable change occurring in air, causing harmful effects on man and domesticated species. The common air pollutants are Dust, Smoke, Carbon monoxide (CO), Ammonia (NH3), Sulphur dioxide (SO2), Hydrogen sulphide (H2S), Nitrogen dioxide (NO2), Hydrogen cyanide, Hydrogen fluorides, Chlorines, Phosgenes, Arsines, Aldehydes, Ozone, Ionising, and radiations. CO2 is not a normal air pollutant. There is 0.03% CO2 in the air; its higher percentage is the cause of greenhouse effect.
Types of Air Pollutants
It is two types :
Primary Air Pollutants:
Air is polluted by poisonous gases and undesirable substances. They are released by burning fossil fuels. These substances are called primary air pollutants. The primary air pollutants are the following :
Sulphur dioxide (SO2).
Benzopyrene (hydrocarbon) is released from cigarette smoke.
Ammonia (NH3).
Oxides of nitrogen.
Carbon monoxide (CO).
Lead (Pb).
Secondary Air Pollutants
Secondary air pollutants are poisonous substances formed from primary air pollutants. In bright sunlight, nitrogen, nitrogen oxides, hydrocarbons, and O2 interact to produce more powerful photochemical oxidants like ozone (O3), peroxyacetyl nitrate (PAN), aldehydes, sulphuric acid, peroxides, etc. All these constitute photochemical smog, which retard photosynthesis in plants.
Causes of Air Pollution
Agriculture: Hydrocarbons released by plants, pollen grains, insecticides, etc., cause air pollution.
Dust: Dust in the air is increased by dust storms, wind, volcanoes, automobiles, etc.
Industries: Combustion of fossil fuels like coal, petroleum, etc. Industrial smoke is the main source of pollution.
Automobiles: The combustion of petrol and diesel in automobiles releases harmful gases into the air. They also produce dust.
Ionizing radiations: Ionizing radiations include alpha particles, beta particles and gamma rays. They are released into the air by testing atomic weapons.
Freons: The use of freons and other chloro-fluoro-carbon compounds in refrigerants, coolants, and as filling agents in aerosol also causes pollution.
Aerosols: Aerosols are small particles of all sorts of solid or liquid substances suspended in the air. They block the stomata of plants and prevent the gaseous exchanges between plants and the atmosphere. They may also change the climate of an area.
Effects of Air Pollution
Diseases
Air pollution results in several respiratory disorders and heart diseases in humans. In recent decades, the number of lung cancer cases has increased. Children living near polluted areas are more prone to pneumonia and asthma. Many people die each year due to air pollution's direct or indirect effects.
Global Warming
As a result of greenhouse gas emissions, there is an imbalance in the gaseous composition of the atmosphere. This led to
The changes in the surface air temperature,reffered to as the global temperature, brought about by the enhanced green house effect, which is enduced by emmission of greenhouse gases into the air.
ENVIRONMENTAL POLLUTION
Pollution is the process of releasing the substance to the Environment which can bring the harmful effect to both a living and non- living things Or
This is the occurrence of the foreign substance at wrong time which can bring the effect to living or non- living things in the environment.
Example;
When feces and urine are discharged to the environment or water or land can cause bad-smell at the same time may cause the “Water-borne disease”.
TYPES OF POLLUTION
The type of pollution may depend on the place which pollutants are deposited
These are;
Climate Change All over the World .pptxsairaanwer024
Climate change refers to significant and lasting changes in the average weather patterns over periods ranging from decades to millions of years. It encompasses both global warming driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. While climate change is a natural phenomenon, human activities, particularly since the Industrial Revolution, have accelerated its pace and intensity

Characterization and the Kinetics of drying at the drying oven and with micro...Open Access Research Paper
The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.
UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.
