No reliable information has been identified on phototransformation of biphenyl in water. However, the studies of Gagel and Michael (1983) and Saeger (1979), which were considered unreliable (Klimisch 3), can be used in a weight-of-evidence approach to indicate that direct photolysis of biphenyl in water is not a process significantly contributing to degradation of biphenyl in the environment.
Gagel and Michael (1983) did not observe any significant photolysis
after 29 days of exposure to direct sunlight. Saeger (1979) observed 9%
degradation after 28 days of exposure to direct sunlight compared to
dark controls. However, the reduction in test substance concentration
appeared to be at least partially due to other processes, of which
volatilization is most likely the most important. Although these two
studies were considered not reliable, they can be used in a
weight-of-evidence approach to indicate that direct photolysis of
biphenyl in water is not a process significantly contributing to
degradation of biphenyl in the environment.
