Concentration of polycyclic aromatic hydrocarbons in water samples from different stages of treatment

Abstract

Abstract. The aim of this study was to analyze the presence and concentration of selected polycyclic aromatic hydrocarbons in water samples from different stages of treatment and to verify the usefulness of semipermeable membrane devices for analysis of drinking water. For this purpose, study was conducted for a period of 5 months. Semipermeable membrane devices were deployed in a surface water treatment plant located in Lower Silesia (Poland). To determine the effect of water treatment on concentration of PAHs, three sampling places were chosen: raw water input, stream of water just before disinfection and treated water output. After each month of sampling SPMDs were changed for fresh ones and prepared for further analysis. Concentrations of fifteen polycyclic aromatic hydrocarbons were determined by high performance liquid chromatography (HPLC). Presented study indicates that the use of semipermeable membrane devices can be an effective tool for the analysis of aquatic environment, including monitoring of drinking water, where organic micropollutants are present at very low concentrations.

Applications for Passive Sampling of Hydrophobic Organic Contaminants in Water—A Review

“…Namely, inference of sorption of terpenes to carbonaceous geosorbents [116,117], sediment remediation strategies [118][119][120], and a bioretention cell for stormwater treatment [121]. Passive sampling coupled to target chemical analysis and toxicological analysis was used to investigate operational multistage treatment process for petroleum wastewater and drinking water [122][123][124][125][126]. Most studies investigated municipal wastewater treatment.…”
