At analyte concentrations ≥1 μg/L, aqueous samples can be analyzed by direct injection without extraction. In municipal ,wastewater,, six diesters and one monoester were unambiguously identified by comparison with synthesized reference material. DEHP showed highest concentrations of 60 and 5 μg/L in raw and treated ,wastewater,, respectively.
