Effects of Perfluoroalkyl Substances on Immune Function in Wildlife

Quick fact

In a study of wild river otters, higher levels of PFAS in their blood were associated with reduced antibody responses to a common virus, suggesting that these 'forever chemicals' can impair immune defenses in free-ranging wildlife.
