The Ministry of Ecology and Environment released the "Technical Guide to Marine Biological Water Quality Standards (Trial)" (HJ1260-2022)

A few days ago, the Ministry of Ecology and Environment issued the "Technical Guide to Marine Biological Water Quality Standards (Trial)" (HJ1260-2022). This standard is organized by the Ministry of Ecological Environment's Regulations and Standards Division, led by the National Marine Environment Monitoring Center, and jointly completed with the China Institute of Environmental Sciences and Minjiang Academy. The benchmark of marine environment is an important part of the modern environmental governance system. It is the foundation and scientific basis for formulating marine environment standards. It can provide important support for evaluating marine ecological risks. HJ1260-2022 is the first standard for regulating the benchmark derivation of my country's marine environment. The preparation work was launched at the end of 2019, which lasted two and a half years. The preparation group fully absorbed and borrowed the results of scientific research at home and abroad. In terms of methodology, it is stipulated that the species sensitivity distribution method is used for benchmarking. This is the mainstream method that derives freshwater and marine biological water quality internationally today. method. In terms of technical requirements, the characteristics of my country's marine ecosystems and the current foundation of the existing work have been fully considered: first, the toxic data of my country's marine species is required to derive the benchmark of marine biological water quality; The "5 subjects and 8 types" of the characteristics of my country's marine biological zone departments at least toxic data are required; the third is the calculation method of the same effect of homogeneous acute value/chronic value proposed to solve the problems of different types of toxic effects of different types of toxic effects. The purpose of protecting my country's marine species. In the next step, the basic data sets will be derived from the promotion of the development of pollutants' marine biological water quality and benchmarks based on HJ1260-2022. During the "Fourteenth Five -Year Plan" period, the Ministry of Ecology and Environment will regularly organize national technical training to allow more scientific research institutes and scientific researchers to join the marine benchmark team.
