ECHA has produced guidance on how to assess the reliability of data [2]. Dependable and relevant ecotoxicological data are necessary to derive standard values for critical concentrations in the environment.

Klimisch score – Wikipedia

Klimisch score has been criticized for favoring studies conducted under Good Laboratory Practice guidelines, which are mostly industry-funded studies. We have been participating in a project aiming at establishing a new methodology to evaluate ecotoxicological studies that are more precise and reliable than the existing one. According to Beronius and colleagues, academic research is often not conducted in accordance with good laboratory practice GLP and study kllmisch guidelines such as those by the Organisation for Economic Cooperation and Development OECDbecause academic scientists may want to consider most sensitive endpoints for klimksch no guidelines are available.
