The complex biology and toxicology of endocrine disrupting compounds (EDCs) makes toxicity testing as well as evaluation of data for risk assessment difficult. Standardized test guidelines have previously been questioned as to their applicability for evaluating EDC toxicity. However, several guidelines have been updated and enhanced in an effort to better cover EDCs. Also, EDC toxicity is a very active research field and a lot of toxicological data are generated in research studies NOT conducted according to standardized guidelines. Our previous work indicates that differences in how the reliability and relevance of toxicity studies are judged may vary greatly between risk assessments of the same compound and may result in different conclusions about the size and nature of health risks. Further, the process of data evaluation is in many cases in-transparent. The purpose of this on-going study is to contribute to making health risk assessments of EDCs more transparent, systematic, and predictable. The investigation is conducted as a literature study using the EDC bisphenol A (BPA) for a case study. We scrutinize and compare the strengths and weaknesses of both guideline and non-guideline studies evaluating developmental neurotoxicity of BPA. One goal is to further assess the applicability of standardized guidelines in this case. Another aim is to propose improvements in the process of data reporting of non-guideline studies and recommend criteria for the evaluation of data in order to facilitate risk assessment of EDCs.
