Freshwater Water-Quality Criteria for Chloride and Guidance for the Revision of the Water-Quality Standard in China. [PDF]

open access: yesInt J Environ Res Public Health, 2023
The chloride in water frequently exceeds the standard; directly quoting foreign water-quality criteria (WQC) or standards will inevitably reduce the scientific value of the water-quality standard (WQS) in China. Additionally, this may lead to the under- or overprotection of water bodies. This study summarized the sources, distribution, pollution status,
