The occurrence and distribution of 14 organophosphate (OP) triesters and 5 diesters were investigated in sludge from eight sewage treatment plants (STPs) in Beijing, China, during 2008-2014. Tri(2-ethylhexyl) phosphate (TEHP) and tri-m-cresyl phosphate (TCrP) were the predominant triesters with the average concentration of 233-137 μg/kg, respectively. Also, the polar and hydrophilic trimethyl phosphate (TMP) and triethyl phosphate (TEP) were detected in 19% and 74% of sludge samples… CONTINUE READING
