  "term": "PCBs",
  "field": "Environment",
  "definition": "PCBs, or polychlorinated biphenyls, are a group of man-made organic chemicals with a range of toxicity. Although manufacturing of PCBs was banned in the U.S. in 1979, PCBs are long-lasting in fish tissue and in bottom-sediments of rivers and lakes. PCBs in fish that are eaten by humans and wildlife can build up and may have cancer-causing and other health effects. PCB contamination has caused many fishing bans and warnings.",
