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.
Andrew Kolodny's lack of knowledge of pharmacology is legendary. His chemistry must be far worse. Should I be flattered when he appears to be copying mine? "Imitation is the best form of flattery." Charles Caleb Colton, 1824 ... "Except when it makes me want to puke." Josh Bloom, 2019
We would like to believe that most retractions are due to honest errors. But a new paper found that most retractions in chemistry and similar fields are due to actions that are much worse. However, there may be a silver lining in the data.
A couple of years ago Panera Bread went crazy. Those high up in the corporation decided that selling really great tasting food was no longer a sufficient strategy. No, they reasoned, if Panera Bread wanted continued success it needed to go on a full-frontal assault against science. 
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.
It is very tempting to purposefully mislabel a product if you can make extra money and get away with it. But, using isotope analysis, chemists have devised a way to discriminate conventional and organic milk.
The Florida man who was arrested for synthesizing the "Mother of Satan" claims that he was just making fireworks. Uh-huh. Celebrating the Fourth of July early, we suppose? Here, we explain the chemistry behind the explosive.
Unlike human skin or electronic gadgets, aging makes red wine better. While the reasons are complex, they all boil down to chemistry.
Laetrile, which is found apricot seeds, has been used by quacks to "treat" cancer for 70 years. It works, assuming that your goal is to poison yourself. But cancer claims, which were ridiculous in the 1950s, continue today. Psst. Keep this secret. It's cyanide, no more, no less. Don't let the screwballs tell you otherwise. 
Veteran New York Times columnist Nicholas Kristof fancies himself an expert in chemistry and toxicology. Chemists and toxicologists disagree.
