CHEMISTRY AND THE ENVIRONMENT
air is 78% nitrogen, 21% oxygen, 1% noble gases and carbon dioxide
co2 formed from complete combustion of carbon containing fuels. effect is increased global warming so climate change
oxides of nitrogen formed from car engines. effects - respiratory problems, acid rain, photochemical smog
carbon monoxide formed from incomplete combustion of carbon containing fuels. effects are that it is a toxic gas
particulates formed from incomplete combustion of carbon containing fuels. effects are cancer, increased respiratory issues
sulfur dioxide formed from combustion of fossil fuels containing sulfur compounds. effect is acid rain
methane formed from decomp of vegetation and waste gases from animal digestion. effect is increased global warming so climate change
reducing risk of climate change
planting more trees
reduction in livestock farming
decreased use of fossil fuels
increasing use of hydrogen and renewable energy
reducing risk of acid rain
use of catalytic converters in engines
reducing emission by using low sulfur fuels or flue gas
desulfurisation with calcium oxide
catalytic converters converts the pollutants into harmless substances that are removed through the exhaust pipe
2CO + 2NO -> 2CO2 + N2
water from natural sources
dissolved oxygen
metal compounds
plastics
sewage
harmful microbes
nitrates from fertilisers
phosphates from fertilisers and detergents
