The vast physico-chemical diversity of xenobiotics also implies widely varying toxicological effects on humans. The adverse impact of, e.g. mycotoxins, a group of fungal food toxins, range from liver carcinogenicity (aflatoxins), nephrotoxicity (ochratoxin A), estrogenicity (zearalenone) to inhibition of protein synthesis and mitochondrial function (trichothecenes) . Xenoestrogens may immensely impact hormone homeostasis and endocrine disruption, especially in critical time windows, since they interfere with the endocrine system, partly even at extremely low concentrations . Estrogenic chemicals occur, for example naturally in plants (phytoestrogens) like genistein or daidzein and synthetic estrogens may be present in pharmaceuticals, insecticides and plasticizers ).
