The US military has used firefighting foams containing per- and polyfluoroalkyl substances (PFAS) for several decades. The Department of Defense (DoD) has designated PFAS as emerging contaminants due to their long environmental persistence, contamination of drinking water supplies and potential associations with several health outcomes (including cancer).
In this half-hour EDC Strategies Partnership webinar, Dr. Mark Purdue presented findings from a recent study investigating serum PFAS concentrations and their associations with testicular cancer risk among Air Force servicemen, using samples from the DoD Serum Repository.
The study found an association between military firefighting work and elevated serum levels of certain PFAS. The study also found a relationship between PFOS serum levels and risk of testicular germ cell tumors.
This webinar was moderated by Dr. Rachel Massey, Senior Science and Policy Advisor at CHE.
