Environmental

PFOS is persistent, bioaccumulative and toxic to mammalian species... Its persistence, presence in the environment and bioaccumulation potential indicate cause for concern. It appears to be of low to moderate toxicity to aquatic organisms but there is evidence of high acute toxicity to honey bees.

NOTE:

• Exposure to PFOS is ubiquitous, found in human and wildlife tissues around the world.

• PFOS is remarkably persistent. For example, PFOS does not show the slightest sign of degradation when boiled in nitric acid for an hour.

• PFOS is known to be toxic in laboratory animals (rats, mice, monkeys) at levels close to the range already found in animals and people in the real world.
