One of them is CO2. Another is methane
A substance discharged into the air
the answer to this question is pretty simple and it primary pollutants
burning fossil fuels that produce air pollutants containing sulfur and nitrogen
Everyday activities such as driving cars, using household cleaners, and burning fuels can release pollutants into the air. These pollutants can react with other compounds in the atmosphere and lead to the formation of new particles or gases, altering the composition of the air. Over time, this can impact air quality and human health.
The human activity that causes the most air pollution is the burning of fossil fuels, such as coal, oil, and gas. These fuels release harmful pollutants like carbon dioxide, sulfur dioxide, and nitrogen oxides into the atmosphere, contributing to climate change and poor air quality.
Secondary pollutants can be more harmful than primary pollutants because they are often produced through chemical reactions involving primary pollutants and can be more toxic or have a greater impact on human health and the environment. Secondary pollutants can also have longer atmospheric lifetimes and travel further distances, contributing to air quality issues on a regional or global scale.
because man still makes pollutants
Two main human sources of primary air pollutants are industrial activities, such as burning fossil fuels and manufacturing processes, and vehicle emissions from transportation including cars, trucks, and planes.
Human-made pollutants include carbon dioxide from burning fossil fuels, methane from agricultural activities and landfills, nitrogen oxides from vehicles and industrial processes, and chlorofluorocarbons (CFCs) from air conditioners and refrigerants. These pollutants contribute to air pollution, climate change, and ozone depletion.
Pollutants dumped into the air can eventually get into your body when you eat, drink and breathe. Pollutants in the air fall to earth with the rain drops and snow flakes. The pollutants then become more and more concentrated by biomagnification as they move up the food chain to you.
Foreign substances in the atmosphere are called air pollutants. These pollutants can come from various sources such as vehicle emissions, industrial processes, and natural sources like wildfires. They can have harmful effects on human health, the environment, and climate.
