The burning of coal releases poisonous sulphur dioxide into the atmosphere. The resulting acid rain corrodes rocks and vegetation. The survival of plants, animals and fish is threatened. In response, the European Community put in place measures to curb sulphur emissions from power stations by half.
The clip can be used for revision of pollution emissions. Discuss the impurities that are present in fossil fuels and work with students to write up equations that explain the creation of acid rain. Students could investigate the effects of acid rain compared to rain, including how it affects life and the rate of weathering of rocks and building materials. Investigate chemical analysis techniques that are used to monitor environmental quality.
