in January 2024, the state of Connecticut filed two lawsuits against 28 chemical manufacturers. One lawsuit is related to PFAS in firefighting foam, and the other is about PFAS in stain-, water-, and heat-resistant consumer
Like most contaminants, PFAS move naturally- through lakes and rivers, soil, and human bodies.. On top of that, there are a lot of individual compounds in this chemical group — which means PFAS data can vary widely. For example, thisinteractive contamination mapshows how levels differ across...
most degradation methods require harsh processes using intense pressure- in some cases over 22 mega- pascals — or extremely high temperatures — sometimes upwards of 1,000℃ - to break the chemical bonds.(虽然 些科学家已经找到了相对简单的方法来分解选定的PFAS,但大多数降解方法都需要使用高压(在某...
