It does not remain in the body due to its breakdown and removal. Biphenyl dissolves poorly when mixed with water. Most releases of biphenyl to the U.S. environment are to air. In air, biphenyl breaks down to other chemicals or settles as dry deposits to water or land. Biphenyl attaches to solid material in water.
Microorganisms living in water and in soil break down biphenyl to other chemicals.
Because it is a solid that binds to soil, biphenyl is not likely to move through the ground and enter groundwater. Plants and animals may store small amounts of biphenyl. Effects of biphenyl on human health and the environment depend on how much biphenyl is present and the length and frequency of exposure. Effects also depend on the health of a person or the condition of the environment when exposure occurs. Workers exposed to biphenyl fumes for short periods of time have experienced nausea, vomiting, irritation of the eyes and respiratory tract, and bronchitis.
