The Right Chemistry: What's that stink near ginkgo trees in the fall?

Article content “Gee, I don’t know why people don’t pick up after their dogs. It stinks here,” moaned a friend as we were walking down a tree-lined street in Washington.

The Giants obviously like Robinson and believe he can bring something they need to their defense. So who is he as a player, and what does he bring to the field?

The Right Chemistry: The problems with PFAS

The Right Chemistry: The problems with PFAS Chemicals used in certain cross-country ski waxes, non-stick surfaces and fire-fighting foam, among other things, also have major downsides. Author of the article: Joe Schwarcz  •  Special to the Montreal Gazette Publishing date: May 14, 2021  •  4 hours ago  •  5 minute read  •  Cross-country skiers are loath to give up fluorinated waxes because they reduce friction, and when race results are measured in fractions of a second, wax makes a difference, Joe Schwarcz says. Nevertheless, the International Ski Federation is poised to ban fluorinated waxes, he adds. Photo by Lisa Rathke /The Associated Press Article content Say “perfluoroalkyl substances.” That’s a mouthful, right? Luckily, we can get away with using the acronym PFAS, pronounced “peefas.” But the real question is whether we are getting a literal mouthful of these chemicals when we eat or drink. Time to get an earful about PFAS.
