Emission during coal gasification
Coal gasification is a process in which lignite and black coal is turned into combustible gas under high temperatures and pressure. As a result of incomplete combustion carcinogenic substances can be released. The Subcommittee on the Classification of carcinogenic substances of the Health Council, recommends to classify the emission, which is formed during coal gasification, as known to be carcinogenic to humans (comparable with EU-category 1A). De Subcommittee, furthermore, recommends to classify the emission as concern owing to the possibility that it may induce heritable mutations in the germ cells of humans (comparable with EU-category 2).
