The National Academies of Science (NAS) created a report three (3) years ago because there are so many toxic chemicals and pollutants in our air, water, food, and consumer products. The report, entitled "Science and Decisions: Advancing Risk Assessment", directed at government agencies such as the EPA and the FDA, about how to use science to protect health.
As we approach the third anniversary of the NAS report, it's a good time to look at the four most important recommendations from this impressive panel of scientists. Here's a summary based on their recommendations:
- Identify and incorporate variability in human exposure and vulnerability into health assessments, so that all people are better protected.
- When information is missing or unreliable, use science-based default assumptions that protect health, rather than waiting for more data, to speed up the chemical assessment and decision-making processes. There should be a clear set of criteria for when to depart from default assumptions.
- In assessing the risk of chemicals, incorporate information about the potential impacts of exposure to multiple chemicals. Consider other factors, such as exposure to biological and radiological agents, and social conditions.
- Because the population is exposed to multiple chemicals and there is a wide range of susceptibility to chemical exposures, it cannot be presumed that any—even low level—exposures are risk-free. It should be assumed that low levels of exposures are associated with some level of risk, unless there are sufficient data to contradict this assumption.
Just this week, the President of the American Association for the Advancement of Science (AAAS) stated that she was "scared to death" by the anti-science movement …spreading, uncontrolled, across the US and the rest of the western world." It is becoming increasingly clear that the anti-science movement is fueled and funded by a small group of major corporate interests and individuals. Read more in this recent expose in the Guardian. The goal of the attack on science is to stop much-needed government regulations on toxic chemicals and other pollutants (such as greenhouse gases) that harm health. One sign of the success of the anti-science movement is that this important NAS science report has been sitting unheeded for nearly three years. It's time for the EPA and FDA to sit up and take notice.
