Peer-reviewed article on defaults used in consumer exposure estimation

An article on a research project performed by FoBiG on behalf of the German Federal Institute for Risk Assessment (Bundesinstitut für Risikobewertung (BfR)) was recently published in Regulatory Toxicology and Pharmacology. Default values used in tier 1 tools used for consumer exposure estimation (ECETOC TRA, EGRET (ESIG Consumer GES Risk and Exposure Tool) and REACT (Reach Exposure Assessment Consumer Tool)) were compared and consequences of differences in default values were discussed. The results of the study show that the defaults are generally conservative, but may potentially lead to underestimated exposures if modified defaults are not well founded.
