Coal tar was one of the first chemical substances proven to cause cancer from occupational exposure, during research in 1775 on the cause of chimney sweeps' carcinoma. [13] Modern studies have shown that working with coal tar pitch, such as during the paving of roads or when working on roofs, increases the risk of cancer.
A video from 2008 on the history of black lung disease. In 2013, BLD resulted in 25,000 deaths down from 29,000 deaths in 1990. [10] Between 1970 and 1974, prevalence of BLD among US coal miners who had worked over 25 years was 32%; the same group saw a prevalence of 9% in 2005–2006. [20]
Aflatoxin B 1, a toxin produced by the fungus Aspergillus flavus which is a common contaminant of stored grains and nuts is a known cause of hepatocellular cancer. The bacteria H.

One can produce a tar-like substance from corn stalks by heating them in a microwave oven. This process is known as pyrolysis. Tar is a dark brown or black viscous liquid of hydrocarbons and free carbon, obtained from a wide variety of organic materials through destructive distillation. Tar can be produced from coal, wood, petroleum, or peat. [1]
Coal tar can lead to health risks from long-term exposure. ... Environmentalists say the 11-acre site near the Norfolk Southern Railroad is likely still leaking cancer-causing materials into the ...
Coal ash contains many toxic substances that may affect human health, if people are exposed to them above a certain concentration in the form of particulate matter.So it is necessary to avoid situations in which employees working in coal-fired power plants or public members living close to coal ash landfills will be exposed to high coal ash dust concentrations.

IARC group 1 Carcinogens are substances, chemical mixtures, and exposure circumstances which have been classified as carcinogenic to humans by the International Agency for Research on Cancer (IARC). [1] This category is used when there is sufficient evidence of carcinogenicity in humans.
Georgia Power’s Plant Bowen was the second most-deadly power plant in the study, likely responsible for 7,500 deaths as far away as New York state.
