PCBs and Human Health


hans-joachim-lehmlerA University of Iowa faculty member is studying how contaminants move through the food chain, causing diseases in humans.

Hans-Joachim Lehmler, from the UI Department of Occupational and Environmental Health, is studying legacy pollutants like polychlorinated biphenyls (PCBs) and halogenated pesticides in the environment and how they impact human health.

PCB’s have been linked to cancer, autism, and hormone irregularities. Although their use was banned in the 1970’s, the pollutants are present in many bodies of water and can spread to humans in many ways, including consumption of fish.

By better understanding how organisms, like fish and humans, process PCBs, his team can determine how PCBs function in nature, ultimately protecting humans from their harmful effects.
