Brief summary
This is a study to assess the effect of 12 months of blood or plasma donation on serum PFAS levels in a cohort of Metropolitan Fire Brigade (MFB) firefighters. The purpose of the study is to determine if regular blood donation (i.e. whole blood, or plasma donation) will be effective in reducing serum PFAS levels. Participants will be randomly allocated into one of the following three groups: a whole blood donation, a plasma donation or an observation only for a 12-month period. Group 1: Blood donation every 12 weeks Group 2: Plasma donation every 6 weeks Group 3: Observation alone The study will run for a total of 18 months (approximately 3 months screening and randomisation, 12 months intervention and 3 months follow up).
