environmental risk assessment

An email from Dr. Kan Shao, a professor at Indiana University School of Public Health, states that EPA’s current version of Benchmark Dose Software modeling is “extremely misleading and not scientifically justified.” It is very unusual for a scientist who has been deeply involved with the EPA in developing risk assessment modeling to openly criticize the EPA. This requires a deeper dive into this issue.
Science should always be open to new approaches and ideas. Perhaps this seems self-evident, but although this may sound good in theory, many scientists view new approaches challenging their long-held beliefs with skepticism or downright hostility. Rather than rationally examining ideas that cause discomfort, ideas are off-handedly dismissed, and the people advancing them are attacked. This is the scientific version of “cancel culture.”
