The Environmental Impacts of Coal

The Environmental Impacts of Coal

Pollution from coalfired power stations is released in four main ways; (i) as fly ash from the smoke stack, (ii) bottom ash which stays at the bottom after the coal is burned, (iii) waste gases from the scrubber units (which are chemical processes used to remove some pollutants) and (iv) gas released into the air. Table 1 shows the health effects of the main coalfired power plant pollutants ...
