the answer to this question is pretty simple and it primary pollutants
CFC's (destroy the ozone layer), carbon monoxied, carbon dioxide, sulfur oxides, nitrogen oxides..This is also known as primary pollution. :(
metano.
created
One of them is CO2. Another is methane
A substance discharged into the air
burning fossil fuels that produce air pollutants containing sulfur and nitrogen
Two main human sources of primary air pollutants are burning fossil fuels and transport. Transport is actually defined as a necessary evil.
because man still makes pollutants
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.
Some Primary pollutants are like when humans directly put them in the air Secondary pollutants are like when pollutants react with Primary and other Primary pollutants.
they are Gaseous
The air quality in a busy city is typically poorer due to higher levels of pollution from traffic, industry, and human activity. In contrast, the air quality in a forest is usually cleaner and fresher, with higher levels of oxygen and lower levels of pollutants, as trees help filter the air and absorb pollutants. Forests also have a higher concentration of natural compounds that contribute to air quality, such as phytoncides.
Air pollutants.
England does still have air pollution. This is because there are still factories that still have pollutants that are released into the air.
