Abstract

The occurrence and spatiotemporal distribution of 12 organophosphate esters (OPEs) were investigated in the sediments collected from Taihu Lake. Compared to the same lake in 2012 (3.4-14 ng/g dw), the concentrations of ∑12 OPEs in sediments ranged from 10.76 to 335.37 ng/g dw and from 8.06 to 425.39 ng/g dw in 2015 and in 2016, respectively, indicating that the OPEs levels in Taihu Lake have aggravated, recently. TEHP was the most abundant compound of the OPEs, which suggested that TEHP was the most widely used around Taihu Lake recently. The positive correlations between some of individual OPEs and the principal components analysis suggested the same potential sources for them. The strong positive correlation between ∑BPs and TOC content indicated that TOC content was one of the factors affected the distribution of ∑OPEs in the sediment. Risk quotient (RQ) for OPEs showed no high eco-toxicity risk in sediment for aquatic organisms.
