Are “safe” exposure levels really “safe”?

Health risk assessment is the method that regulators use to determine whether chemicals in the environment pose a risk to people’s health and how much exposure to the chemical produces these effects. Unfortunately, current human health risk assessments don’t capture everyone’s risk level. Our recent paper, Application of Probabilistic Methods to Address Variability and Uncertainty … Continue reading Are “safe” exposure levels really “safe”?
