Chromium(III) is an essential nutrient for humans and shortages may cause heart conditions, disruptions of metabolisms and diabetes. But the uptake of too much chromium(III) can cause health effects as well, for instance skin rashes. Chromium(VI) is a danger to human health, mainly for people who work in the steel and textile industry.

Coal Mining. Health effects from coal mining include: the release of methane (CH 4), a potent greenhouse gas estimated to account for 18% of the overall global warming effect triggered by human activities (CO 2 is estimated to contribute 50%).; the release of carbon monoxide (CO) from explosives, which pollutes the air and poses a health risk for mine workers.
