Do you use well water? Reduce your risk If you think your health has been affected by exposure to PCBs, contact your health care professional. In the IUPAC system used in the examples above, the numbers at the beginning of the name specify the sites where chlorines are attached to the phenyl rings.

What are PCBs?

If there is a concern regarding contamination arising from a site where contaminants have been reported further investigation is necessary to assess groundwater quality. This is not a comprehensive list of current regulations.

Internal exposure in humans Several methods have been developed to assess internal exposure the amount absorbed by the body and distributed to various organs and tissues to PCBs.

Facility signs and dates the manifest when the waste was received, except as noted in the discrepancy space of the manifest, or when the waste was rejected as noted in the manifest discrepancy space. Studies in humans have suggested effects similar to those observed in monkeys exposed to PCBs, including learning deficits and changes in activity associated with exposures to PCBs.

Polychlorinated Biphenyls (PCBs)

See below for further information on: Summary Level 2: PCBs can accumulate in the leaves and above-ground parts of plants and food crops. PCBs belong to a broad family of man-made organic chemicals known as chlorinated hydrocarbons. EPA evaluates all of the available data in determining the potential noncarcinogenic toxicity of environmental contaminants, including PCBs.

Other reported health effects in animals have included immune system changes, behavioural alterations and impaired reproduction. Many studies in animals and human populations have been performed to assess the potential carcinogenicity of PCBs.

Facility requirements for preparing a new manifest for rejected wastes that must be sent back to the generator. Should odours arising from ground sources be detected, avoid the inhalation of these odours and contact SA Health's Scientific Services for advice.

However, studies that do not demonstrate an association between exposure to PCBs and disease should not be characterized as negative studies.

PCBs , or polychlorinated biphenyls , are a class of man-made organic chemicals. The commercial production of PCBs started in 1929 but their use has been banned or severely restricted in many countries since the 1970s and 80s because of the possible risks to human health and the environment.
