Environmental hazard assessment of chemicals and products. Part VII. A critical survey of exposure data requirements and testing methods

摘要: Abstract Environmental exposure analysis may be used for a preliminary judgement — even in the absence of effect data on possible environmental behaviour chemicals, based relatively few, exactly measurable physico-chemical parameters from which transfer between media and (at least partly) also degradation can estimated. However, presently required by legislation (EU) are frequently concepts experiences 70's, period highly lipophilic compounds were center interest. Although these chemicals continue causing severe problems, polar have recently been identified as potentially dangerous substances. Therefore, it is to expected that requirements, testing procedures modelling will extended improved order meet new challenges. In identify gaps present-day analysis, transfer- degradations pathways most important survey methods available measuring relevant attempted. Special emphasis given internationally agreed (OECD).
