Composition of Industrial Smoke:
Industrial smoke comprises a wide range of pollutants, each with its own chemical and physical characteristics. Particulate matter (PM) consists of tiny particles suspended in the air, classified based on size into PM10 (particles with a diameter of 10 micrometers or less) and PM2.5 (particles with a diameter of 2.5 micrometers or less). These particles can contain various substances, including organic compounds, metals, and toxic chemicals, posing risks to human health and the environment.
Sulfur dioxide (SO2) is a colorless gas produced by the combustion of sulfur-containing fuels such as coal and oil. It contributes to the formation of acid rain, which damages buildings, vegetation, and aquatic ecosystems. Nitrogen oxides (NOx), primarily nitrogen dioxide (NO2) and nitric oxide (NO), are generated during combustion processes in industrial boilers, power plants, and vehicles. NOx emissions contribute to smog formation, respiratory illnesses, and ground-level ozone pollution.
Carbon monoxide (CO) is a colorless, odorless gas produced by incomplete combustion of carbon-containing fuels. It can cause adverse health effects by reducing oxygen delivery to the body’s organs and tissues. Volatile organic compounds (VOCs) are a diverse group of organic chemicals that evaporate into the air, contributing to the formation of ground-level ozone and secondary organic aerosols, which can harm human health and the environment.
Heavy metals such as lead, mercury, cadmium, and arsenic are released into the atmosphere during industrial processes such as metal smelting, mining, and combustion of waste materials. These metals can bioaccumulate in the environment, posing risks to ecosystems and human health through exposure via air, water, soil, and food.
Greenhouse gases (GHGs) emitted from industrial sources include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases. These gases trap heat in the Earth’s atmosphere, leading to global warming and climate change. Industrial activities are significant contributors to GHG emissions, primarily through the combustion of fossil fuels for energy production and manufacturing processes.
