6 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. Breathing and heart problems
