There are hundreds of commercial pesticides in use in the world today. From algaecides to virucides, pesticides are used in large quantities in industrial and private agriculture.
Per- and polyfluoroalkyl substances (PFAS) are synthetically made organofluoride chemical compounds. These compounds were originally introduced to the public as an additive to make nonstick cookware, but they were quickly incorporated into all sorts of other products. Commonly known as "forever chemicals", many PFAS compounds do not break down in the environment and there is increasing evidence showing that PFAS exposure can lead to adverse human health.
Microplastics are tiny plastic particles, which can be unintentionally formed as a result of the breakdown of larger plastics.
