Get Biphenyl In Support Of Summary

Biphenyl is a benzenoid aromatic compound that consists of two benzene rings connected by a single covalent bond. Biphenyl occurs naturally in coal tar, crude oil, and natural gas. Formerly used as a fungicide for citrus crops.

Its major uses are in the production of heat-transfer fluids (for example, as an intermediate for polychlorinated biphenyls) and dye carriers for textile dyeing. Lesser uses are as a mould retardant in citrus fruit wrappers, in formation of plastics, optical brighteners, and hydraulic fluids.

They have a high boiling point and do not conduct electricity. They are not soluble in water. Reports in newspapers, radio and television have linked PCBs to cancer and birth defects. PCBs are a toxic substance.

In workers, acute (short-term) exposure to high levels of biphenyl has been observed to cause eye and skin irritation and toxic effects on the liver, kidneys, and central and peripheral nervous systems. Kidney effects have been observed in chronically (long-term) exposed animals.

Studies in animals provide conclusive evidence that PCBs cause cancer. Studies in humans raise further concerns regarding the potential carcinogenicity of PCBs. Taken together, the data strongly suggest that PCBs are probable human carcinogens. PCBs are one of the most widely studied environmental contaminants.

There is evidence that Polychlorinated Biphenyls cause liver cancer in humans and animals. a carcinogen.

Admixture of water to biphenyl in amounts greater than 0.2 was shown to hasten the corrosive failure of aluminum A-1 and SAP-1 alloy and lead to intercrystalline corrosion, as well as embrittling and lowering the strength of the metals.
