Such was the Committee 17 report. As its name suggests, this was a seventeen-member scientific review body convened by the EMS Executive Council to review research in mutagen detection and in population monitoring, assess the risk implications of the data derived from these testing and monitoring systems, and recommend directions for future research and for chemical regulatory policy. The committee s final report was published in Science in 1975 under...

The most frequently used BFRs are polybrominated diphenylethers (PBDEs), tetrabromobisphenol A (TBBPA), and hexabromocyclododecane (HBCD). The use of FRs has been growing rapidly in recent years. BFRs are the most often used FRs, and their market is still growing. However, the estimated annual use of OPFRs in Western Europe was almost twice that of all BFRs combined. Many FRs have been banned for use because of their potential toxicity, environmental occurrence, and accumulation in human tissue. FRs taken off the market are likely to be replaced by others. Although the REACH (registration, evaluation, authorization and restriction of chemicals) regulatory system has been introduced in Europe to improve protection of human health and the environment, it is still necessary to monitor FRs in environmental samples [84, 88].

QSAR model validation mostly serves the purpose of demonstrating the overall prediction quality of the model. In practice, however, the way in which validation is performed largely depends on the model s intended use. If the model is to be applied to a known population of chemicals, regulatory acceptance of the model could depend entirely on the results of validation carried out that is specific to the particular chemical population. The model s validity can be demonstrated by comparing the predicted results with the experimental results on an external test set that is objectively selected from the application population Consequently the unbiased selection of an appropriate test set becomes an essential step in determining the validity of the model. The selected chemicals should represent the diversity of molecular structure and activity of the application population, and the selection process should provide statistically significant data to assess false positives and false negatives.

EPA altered its TSCA compliance inspection priorities over the last five years. In fiscal year 2005 there were 1611 TSCA inspections, of which 1191 involved the core chemical regulatory programs and 420 of which were focused on lead, asbestos, and PCBs. In contrast, in fiscal year 2008 there were 1441 TSCA inspections, of which only 56 were for the core regulatory programs.
