1,3,5-Trichloro-2-(4-nitrophenoxy)benzene in fish, shellfish, and seawater in Tokyo Bay, 1977-1979

Concentrations of 1,3,5-trichloro-2-(4-nitrophenoxy)benzene (CNP) were measured in goby-fish, sea bass, shellfish, and seawater samples collected in the coastal waters of Tokyo Bay. The concentrations of CNP found in goby-fish were in the range of 2.6 to 91,400 ppb in liver, 0.1 to 360 ppb in muscle, trace to 2,900 ppb in short-necked clam, and not detectable to 1.9 ppb in seawater. Although the concentrations in the samples varied with time and place of sampling, the maximum levels were found in the samples obtained in May or June of 1977, 1978, and 1979.
