Peer review, especially peer review of chemical safety/risk assessments, is under assault. Is something inherently wrong with the process of this area of peer review?
Are the small levels of pesticides, herbicides and genetic modifications in our food -- whether human-made or natural -- harmful? Let's put the virus aside for a moment and see what we find.
In short, the public is often worried about chemical exposure, as they should be when such exposure exceeds a safe dose. The public’s interest is best served by trusting experts dedicated to public health protection and not by withholding scientific data from independent analysis.
All chemicals are toxic at some level. Some can cause harm at very small concentrations, while others need a large amount before there's a danger to human health. Even water can be deadly if consumed in large enough amounts. Let's take a closer look at various levels of safety and harm.
Are toxicologists medical doctors? And what does a person need to know to become a toxicologist? Dr. Michael Dourson, aka America's Toxicologist, and Dr. Bernard Gadagbui explain the field of toxicology.
At our 40th-anniversary celebration event in late 2018, Dr. Dourson was introduced to those in attendance at the Washington, DC gala as the nation's toxicologist. Although this welcoming gesture was made somewhat in jest, a quick review of his credentials lends it credence. Let's take a look.
The next Beyond Science and Decisions Workshop XI will be held on February 18-20, 2020 in Cincinnati, Ohio, at the Taft Auditorium of the National Institute for Occupational Safety and Health (NIOSH).
There is wide divergence on the safety assessment of these chemicals, thus making communication with the public extremely difficult.
Safe or low-risk doses for PFOA, and related chemicals by various governments, are currently widely disparate. Fortunately, recent findings in humans may reduce some of this disparity. Efforts to use this newer information should allow for harmonization -- or at least more consistency -- in government positions.
Perfluorooctanoic acid, or PFOA, is a chemical commonly found in household products. Its purpose is to resist stains, grease, and other assaults. And it's been in the news for several years. In many workplaces and communities, PFOA has become a household name while triggering fears of adverse health effects and expensive, never-ending environmental cleanups. What’s going on? Let's take a look.
Veteran New York Times columnist Nicholas Kristof fancies himself an expert in chemistry and toxicology. Chemists and toxicologists disagree.
