چکیده انگلیسی
A method for quantitative determination of 13 organophosphorous compounds (OPs) was developed and applied to influent, primary sludge, activated sludge, biosolids, primary effluent and final effluent from a wastewater treatment plant (WWTP). The method involved solvent extraction followed by solid phase clean-up and analysis by high performance liquid chromatography positive electrospray ionization-tandem mass spectrometry (HPLC(+ESI)MS/MS). Replicate spike/recovery experiments revealed the method to have good accuracy (70-132%) and precision (<19% RSD) in all matrices. Detection limits of 0.1-5Â ng/L for aqueous samples and 0.01-0.5Â ng/g for solid samples were achieved. In the liquid waste stream âOP concentrations were highest in influent (5764Â ng/L) followed by primary effluent (4642Â ng/L), and final effluent (2328Â ng/L). In the solid waste stream, the highest âOP concentrations were observed in biosolids (3167Â ng/g dw), followed by waste activated sludge (2294Â ng/g dw), and primary sludge (2128Â ng/g dw). These concentrations are nearly 30-fold higher than âpolybrominated diphenyl ether (BDE) concentrations in influents and nearly 200-fold higher than âBDE concentrations in effluents from other sites in Canada. Tetrekis(2-chlorethyl)dichloroisopentyldiphosphate (V6), tripropylphosphate (TnPrP), and Tris(2,3-dibromopropyl)phosphate (TDBPP) are investigated for the first time in a WWTP. While TnPrP and TDBB were not detected, V6 was observed at concentrations up to 7.9Â ng/g in solid waste streams and up to 40.7Â ng/L in liquid waste streams. The lack of removal of OPs during wastewater treatment is a concern due to their release into the aquatic environment.
