Question

Quizplus · Accepted Answer

Dioxins are a group of chemically related compounds that are persistent environmental pollutants (POPs). They are known to cause cancer in laboratory animals, and there is evidence to suggest they can cause cancer in humans as well, although the data can be conflicting due to the complexity of human exposure and cancer studies. Humans are primarily exposed to dioxins through the consumption of contaminated foods, rather than drinking water or specific regional living conditions. Incineration of waste, if not done properly, can actually release dioxins into the environment. Dioxins are not specifically byproducts of unleaded automobile fuel combustion.
