Freshwater Water-Quality Criteria for Chloride and Guidance for the Revision of the Water-Quality Standard in China

International Journal of Environmental Research and Public Health, Год журнала: 2023, Номер 20(4), С. 2875 - 2875

Опубликована: Фев. 7, 2023

The chloride in water frequently exceeds the standard; directly quoting foreign water-quality criteria (WQC) or standards will inevitably reduce scientific value of standard (WQS) China. Additionally, this may lead to under- overprotection bodies. This study summarized sources, distribution, pollution status, and hazards China’s we compared analyzed basis for setting WQS limits China; systematically WQC countries, especially United States. Finally, collected screened data on toxicity aquatic organisms; also used species sensitivity distribution (SSD) method derive chloride, which is 187.5 mg·L−1. We put forward a recommended freshwater China: less than 200 not only key point environmental research, but an urgent demand ensure ecological protection results are great significance management organisms, risk assessment, revision WQSs.

Beyond target chemicals: updating the NORMAN prioritisation scheme to support the EU chemicals strategy with semi-quantitative suspect/non-target screening data

Environmental Sciences Europe, Год журнала: 2024, Номер 36(1)

Опубликована: Июнь 12, 2024

Abstract Background Prioritisation of chemical pollutants is a major challenge for environmental managers and decision-makers alike, which essential to help focus the limited resources available monitoring mitigation actions on most relevant chemicals. This study extends original NORMAN prioritisation scheme beyond target chemicals, presenting integration semi-quantitative data from retrospective suspect screening expansion existing exposure risk indicators. The utilises retrieved automatically Database System (NDS), including candidate substances prioritisation, data, ecotoxicological effect physico-chemical other properties. Two complementary workflows using are applied first group into six action categories then rank exposure, hazard results ‘target’ ‘suspect screening’ can be combined as multiple lines evidence support decision-making regulatory research actions. Results As proof-of-concept, new was dataset data. To this end, > 65,000 NDS, 2579 supported by wastewater were retrospectively screened in 84 effluent samples, totalling 11 million points. final identified 677 high priority further actions, 7455 medium 326 with potentially lower Among remaining substances, ca. 37,000 should considered uncertainty, while it not possible conclude 19,000 due insufficient information uncertainty identification screening.
