Regulatory agencies should take a similar approach: chemicals, as sheep, should be assessed and their risk managed by groups. There … Continue reading It’s time to regulate chemicals as classes
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”?
When the U.S. Environmental Protection Agency (EPA) evaluates chemical risks, it assumes for the most part that we are all the same. Or, rather, that some of us might be a little bit more sensitive than others. Ten times more sensitive, to be specific. But that’s not exactly true. When it comes to chemicals in … Continue reading With chemicals that can harm you, one size does not fit all
