But in many cases, it has been replaced with similar hormone disrupting chemicals, like Bisphenol S (BPS). A <a href="https://doi.org/10.1021/acs.est.2c09390">new study</a> from 黑料不打烊 University shows that every day Canadians are exposed to BPS in the fresh foods they eat, as chemicals migrate from labels on the packaging materials into the food.</p> Thu, 16 Mar 2023 12:56:12 +0000 webfull 188129 at /channels /channels/channels/news/greener-way-make-ketones-284242 <p>Researchers at 黑料不打烊 University have discovered a new, more environmentally friendly way to make ketones, an important chemical ingredient in pharmaceuticals.聽 While ketones are found in a wide range of useful chemicals, they are commonly prepared through energy-intensive, multi-step technologies that create significant chemical waste.聽 In an article published online last month in <em>Nature Chemistry</em>, the 黑料不打烊 scientists demonstrate how carbon monoxide, a widely available by-product of combustion, can instead be used to form high-energy chemicals that react directly with benzene to</p> Fri, 26 Jan 2018 20:22:15 +0000 webfull 134503 at /channels /channels/news/mcgill-researchers-lead-development-tool-assess-environmental-risks-chemicals-264686 <p><span>Assessing the risks that toxic chemicals pose to natural ecosystems is a huge challenge, given the thousands of chemicals that require testing. But the task is expected soon to become less daunting, thanks to a new tool being developed by 黑料不打烊 University researchers.聽</span></p> Thu, 08 Dec 2016 15:15:16 +0000 webfull 123615 at /channels
