Chemicals & Chemistry

A recent story about the bizarre symptoms of policemen, who were exposed to street fentanyl, turned out to be anxiety attacks – not fentanyl poisoning. What happened? Yes, it's time for another Dreaded Chemistry Lesson From Hell!
The Environmental Working Group (EWG) is once again warning consumers that their food may be tainted by "forever chemicals." Let's take a look at all the important details the activist group left out.
Is widespread use of artificial sweeteners polluting the environment? If so, what do we do about it? Join us on the latest episode of the Science Dispatch podcast as we take a critical look at the evidence.
Suffering from "climate anxiety," some of America's entitled college students are working to get low-risk pesticides banned from their campuses, in a bid to slow global warming. They all need therapy and a basic science lesson.
Anti-pesticide activist Carey Gillam recently moderated a panel discussion about the weed killer glyphosate. I attended and took notes. Here's what I saw.
Environmental Working Group claims that "obesogenic" chemicals are helping to make everybody fat. Is EWG correct? Next, do we need a COVID booster shot that specifically targets Omicron sub-variants?
Environmental Working Group has again claimed that chemicals in food and consumer products are contributing to obesity. They are mistaken, embarrassingly so.
The FDA recently attempted to ban JUUL vaping products and announced a proposal to cut nicotine levels in combustible cigarettes. The policies are designed to reduce tobacco use—but will they? We have our doubts. Join us for episode 10 of the Science Dispatch podcast.
It is that time of year when my poor dog cowers under the bed as the rocket's red glare of fireworks is seen and heard across the country. Perhaps I am stealing from my fellow writer and chemist, Dr. Bloom, but I just wanted to share what I had learned about the chemistry underlying all that color filling our skies.
The activist group Slow Food recently published a listicle warning consumers about the dangers of pesticides. Let's see if their top-10 list stands up to scrutiny.
In April, the EPA published its draft Integrated Risk Information System (IRIS) Toxicological Review of Formaldehyde (inhalation), a 192-page document. The publication of this document raises issues that go far beyond the health effects of formaldehyde, issues concerning science, policy, the role of our scientific agencies, and the potential overreach of government regulatory authority.  
On Episode 5 of the Science Dispatch Podcast, ACSH contributor Dr. Barbara Billauer recounts the tragic story of the "Radium Girls," a cohort of young women who were gradually sickened and killed by occupational radium exposure in the early 20th century. Subsequent research has shown that their employers knew the girls were at risk, but denied culpability and continuously assured them that all was well. These shocking developments changed the way we view occupational health and safety—providing the foundation for current radiation exposure standards.
