During the year NICNAS consulted the Advisory Group on Chemical Safety (AGCS) on technical matters concerning several existing chemical assessments. The group reviewed and provided feedback on the phthalates compendium, on human health risk assessment methodology issues relating to the assessment of triclosan, an assessment of beryllium, hazard assessments and classifications of decabromodiphenyl ether (decaBDE), pentaBDE and the interim public health risk assessment of certain PBDE congeners.
