Concept:Atmospheric pollution is caused when harmful gases or chemical particles enter the air.
Explanation:Insecticides sprayed on crops or used as fumigants give off volatile organic compounds.
These compounds react with other gases in sunlight to form ground-level ozone, which is an air pollutant.
Sulphur dioxide (
SO2) is a gaseous pollutant made of sulfur and oxygen.
It is produced when sulfur-containing fuels such as coal, oil, or diesel are burned.
Both insecticide vapours and
SO2 can therefore pollute the atmosphere.
Fertilizers and sewage mainly pollute water and soil, not the atmosphere directly.
Answer:The correct atmospheric pollutants in the list are II and V: Insecticides and Sulphur dioxide.
