Abstract
Contamination of phenolic endocrine disrupters in water and fish from rivers and lakes in Europe, America and Japan was reviewed and the bioconcentraton potential of the chemicals and their contamination in the field fish was evaluated. Nonylphenol (NP) and 4-tert-octylphenol (OP) concentrations in the water were on the whole decreasing but bisphenol A (BPA) did not have a definite tendency. The concentrations and the yearly change of the contaminated chemicals had regional differences. In Europe and America, the values of high concentrations were reported in the past but a sharp decrease tendency in the concentrations of NP, nonylphenol monoethoxylate (NP1EO), nonylphenol diethoxylate (NP2EO), etc. was recognized from the survey data in the last few years. The contamination of NP, OP and BPA in fish from rivers and lakes was on the whole predicted by Laboratory bioconcentration factor (BCF) of the chemicals (middle-low bioconcentration potential) . From the evaluation of Field BCF by Laboratory BCF, it was revealed that the values of Field BCF change more largely than those of Laboratory BCF because of the concentration change of the chemicals in the water, conditions of the environment, individual difference in fish, etc. That is, more precise evaluation of their contamination in the field fish will be possible by using Laboratory BCF together with Field BCF.
