Cinnabar (mercury sulphide - HgS) is the single most toxic mineral to handle on earth. It is the worldâs main source of mercury and has been mined since Neolithic times. However, when oxidized, this element will produce methyl mercury and dimethyl mercury, two toxic compounds that cause irreparable harm to the nervous systems of children. It is deadly in small concentrations and can be absorbed through the respiratory tract, intestines, or skin.
Acrylamide is a potentially toxic and potentially cancer-causing substance that can be naturally present in uncooked, raw foods in very small amounts. But for this substance to pose a risk of toxicity or cancer, it must be present in foods in much larger amounts, and these larger amounts do not occur unless those foods have been cooked.
