ABSTRACT

Organic air Pollutants refer to harmful chemicals found in the air which are typically derived from living organisms or contain carbon atoms. These pollutants can come from various sources, such as fossil fuel combustion like vehicles, power plants, or industrial processes. Agricultural activities, natural sources etc. The common types of organic air pollutants include volatile organic compounds (VOCs), particulate matter, polycyclic aromatic hydrocarbon, etc. Photochemical smog, also known as ground level ozone, is a type of air pollution that forms when nitrogen oxides (NOx) and volatile organic compounds (VOCs) react with sunlight, thereby creating toxic pollutants such as ground level ozone (O3), particulate matter (PM) etc. This seminar examines the sources, types, health effects, and environmental impacts of organic air pollutants and photochemical smog, the need for integrated strategies to mitigate their emissions, including transition to cleaner energy sources, implementation of emission controls, and promotion of sustainable transportation options, is advised. By understanding the dual threat of organic air pollutants and photochemical smog, we can develop effective solutions to protect public health and the environment, ensuring a cleaner, healthier future.
