Chemicals & Chemistry

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.
There is a lot of malicious misinformation on the internet about glyphosate. Much of it comes from academia.
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.
Mercaptans (aka, thiols) are some of the vilest smelling chemicals in the galaxy. Yet, they save many lives? If you want to know why you'll have to get through this stinky article.
There is a naturally-occurring chemical called skatole. Its claim to fame is that it is named after, and smells like, fecal matter. It's "synthetic" but also "man-made" and there's a revolting distinction in this case. It's also an additive used in cigarettes and strawberry ice cream (??). Do your "duty" and read this article.
Should you be in the mood to change the color of your pee, this is the article for you. Two drugs and one natural product do the job quite vividly. A colorful chemistry lesson, a party trick, and good bathroom reading!
In these sensitive times, stereotypes are a big no-no. Hopefully, this doesn't apply to chemicals, because there is one group of them called esters. They smell really nice, even though the two components that combine to form esters can smell like foot odor or vomit. A stinky chemistry lesson. Hold your nose and read.
Bisphenol A – a long-used component of polycarbonate plastics, is one of the most studied chemicals in the world. Even the ultra-cautious FDA has declared it safe for people as used. But some scientists have built a career by screaming about how dangerous it is, so we have another paper. Enough already.
A new study reveals that nearly 40% of Europeans want to "live in a world where chemical substances don't exist." Another 82% didn't know that table salt is table salt, whether it is extracted from the ocean or made synthetically.
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).
Gold is known as a noble metal because of its lack of chemical reactivity. But if you treat it right, you can get it to do some cool things. You can chew on it, make some lousy drugs, screw up the environment mining it, and (maybe) even make a super-pricey burger. Really.
