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.

"This FDA-led effort represents a positive step forward as we continue to reevaluate chemicals authorized for use with, and in, food," said Jim Jones, the FDA's deputy commissioner for human foods.
Perfluorononanoic acid, or PFNA, is a synthetic perfluorinated carboxylic acid and fluorosurfactant that is also an environmental contaminant found in people and wildlife along with PFOS and PFOA.
PFAS are a class of man-made chemicals once used in manufacturing that have since been dubbed a pollutant. A new study links them to hypertension in women.
