The document discusses air pollution, its causes and effects. It outlines the primary air pollutants such as particulate matter, carbon monoxide, carbon dioxide, volatile organic compounds, sulfur dioxide, nitrogen oxides and fluorides. Secondary pollutants like photochemical smog and acid rain are also mentioned. Control methods for air pollution include the use of scrubbers, cyclonic separators and electrostatic precipitators to capture particulate matter, and combustion, absorption and adsorption techniques to control gaseous pollutants. The role of Central Pollution Control Board in regulating air pollution in India is highlighted.

Air pollution and it's effects on human healthDivyaBhargavi7
Air pollutions has many adverse effects on human . Many complication include respiratory and cardiovascular complications . So plant a tree try to reduce air pollution. Be a responsible citizen plant a tree save a life .
Air pollution occurs when harmful substances released in or excessive quantities including gases, particles, and biological molecules to Earth's atmosphere. Life expectancy has gone down by 2.6 years due to air pollution. Delhi, Mumbai, Gurugram comes under most polluted cities of the world.

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 French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
