Abstract

Abstract: Owing to the growing public awareness on the safety and aesthetics in water sources, more attention has been given to the adverse effects of volatile organic compounds (VOCs) on aquatic organisms and human beings. In this study, 77 target VOCs (including 54 common VOCs, 13 carbonyl compounds, and 10 taste and odor compounds) were detected in typical drinking water sources from 5 major river basins (the Yangtze, the Huaihe, the Yellow, the Haihe and the Liaohe River basins) and their occurrences were characterized. The ecological, human health, and olfactory assessments were performed to assess the major hazards in source water. The investigation showed that there existed potential ecological risks (1.30 × 10 ≤ RQtotal s ≤ 8.99 × 10) but little human health risks (6.84 × 10 −7 ≤ RQtotal s ≤ 4.24 × 10 −4 ) by VOCs, while that odor problems occurred extensively. The priority contaminants in drinking water sources of China were also listed based on the present assessment criteria. Graphical abstract: Highlights: VOCs with various polarities were screened in typical water sources of China. Ecological, human health and olfactory assessments were simultaneously performed. The risk assessments were used to identify the major hazards by VOCs. The detected VOCs posed potential ecological risks but little human health risks. Odor problems occurred extensively in source water of China. Abstract : Detected VOCs with various polarities caused odor problems and posed potential ecological risks but little human health risks in drinking water sources in China.
