Organophosphate esters in sediment from Taihu Lake,China:Bridging the gap between riverine sources and lake sinks
文献摘要：
Surface sediment samples from Taihu Lake in China and its inflow rivers,along with two lake sediment core samples,were collected and analyzed for organophosphate esters(OPEs).The concentrations of total OPEs varied from 28.60 ng/g to 158.72 ng/g(median:54.25 ng/g)in river surface sediment and from 62.57 ng/g to 326.84 ng/g(median:86.37 ng/g)in lake sediment.Tributyl phosphate(TnBP)was the predominant compound in river surface sediment,and tris(2-butoxyethyl)phosphate was predominant in lake sediment.High contamination occurred in the north-west region,which was related to the high level of urbanization and high usage of OPEs.The sediment-water partition coefficients of OPEs(logKoc)were calculated,showing a significant correlation with logKow(p＜0.05).The concentration and composition of OPEs in two sediment cores varied due to the different sampling locations,with more OPE species found in the northern region than in the southern one.Principal component analysis and positive matrix factorization indicated that sewage discharges,vehicle emissions,and atmospheric deposition were the possible sources of OPEs in Taihu Lake sediments.Tris(l-chloro-2-propyl)phosphate,tris(2-chloroethyl)phosphate,and TnBP were the main OPEs causing ecological risks.
