Abstract

Screening-level ecological risk assessments of di (2-ethylhexyl) phthalate for aquatic organisms in Japanese were conducted using estimated statistic values based on surface water and sediment monitoring data and an effect threshold value determined based on the large aquatic toxicity database. The results of risk characterization showed that all the MOE values calculated using the statistic values of DEHP concentrations in Japanese surface waters and sediments are above 10 indicating minimal risk. It is concluded that the current levels of DEHP poses little concern to aquatic organisms in the majority of Japanese surface waters and sediments.
