Bioaccumulation of PFAS: PFASs from sediments and water can accumulate in marine organisms. Animals higher up the food chain accumulate more PFAS because they absorb PFAS in the prey they consume. In marine species of the food web. Bioaccumulation controls internal concentrations of pollutants, including PFAS, in individual organisms.
Fire-retardant foam, which contained PFAS compounds for decades, often found use at military bases and airstrips, causing costly pollution to nearby water sources. The U.S. Department of Defense ...
