Air Pollution What do we mean by the term pollutant? What are the pollutants that cause air pollution?
There are six common air pollutants: Sulphur dioxide Carbon Monoxide Nitrogen oxides Lead Ozone Particulates
Where do these pollutants come from? Sulphur dioxide Carbon monoxide
Nitrogen oxides Lead
Ozone is formed by a chemical reaction between nitrogen oxides and (VOC) volatile organic compounds in the presence of sunlight. Particulates are made up from nitrates and sulphates, metals, soil, dust.
Why should we worry about these pollutants? Sulphur dioxide - helps form acid rain, contributes to respiratory diseases Carbon monoxide - poisonous gas, blocks oxygen from being carried in the blood Nitrogen oxides – smog (ozone), acid rain, greenhouse gas, water quality Lead – poisonous, attacks the organs Ozone - smog Particulates – smaller particulates are a greater cause of concern.
