11 CRC Drafted GB/T Standards on Ecotox Testing in Force from this August

Among these, the fish acute toxicity test and the ready biodegradability test are both mandatory testing items necessary to the ecotox data report under China’s new substance regular notification. And the soil & sludge adsorption coefficient estimation is usually considered a prior determinant for whether a regular notification can be exempted from two exotox tests - the earthworm acute tox test or the seed germination & root elongation tox test.

Note: Draft proposals of the seven CRC-drafted standards were provided on a 2009 CRC-MEP news alert. Chinese GB/T final versions are not free on the internet while GB standards (in Chinese) are usually for free download. Also going into effect on the same date are four GB/T standards co-drafted by several chemical institutes including the CRC-MEP, which concerns ecotoxicological tests of soil microorganisms, terrestrial plants and digested sludge. All the eleven GB/T standards were released for the first time by the Standardization Administration of China (SAC) at the end of last year. They have been the second release since China enacted and implemented relevant ecotoxicological testing methods in 2009. This group of standards is expected to forcefully promote China’s chemical hazard identification and risk assessment. Reference Links
