Wisconsin’s Department of Natural Resources and Department of Health Services warn residents to limit their consumption of wild fish to prevent possible health problems from chemical contamination, as do many other states. Those problems include a range of health effects, but the four groups of chemicals that trigger consumption advisories – PCBs, mercury, dioxins and PFOS (perfluorooctane sulfate) – have been associated with endocrine disruption, DNR toxicologist Candy Schrank confirmed. Most fish contain at least low levels of mercury, while the other three chemicals are of most concern at specific locations. Chemicals to blame
Mercury: A natural element that is mobilized and emitted into the air via combustion and other activities. Mercury has been shown to affect the cognitive thinking, memory, attention, language, fine motor skills and visual spatial skills of children exposed in the womb.
