Researchers find high levels of PFAS chemicals in rainwater in United States
News
18 Dec 2019 | The Weather Channel
Most of the samples had PFAS concentrations of less than 1 ng/l, or 1 ppt, but several were about 4 ng/l. The highest total concentration was nearly 5.5 ng/l in a sample from Massachusetts. For drinking water, some states have proposed setting the level at which some type of official action is required at 2 nanograms per liter.

Environmental Contaminants and Congenital Heart Defects: Focus on PFAS, PAHs, and Other Emerging Exposures
Science
30 Nov 1926 | Clin Chem
PFAS, PAHs, and other pollutants may be associated with disrupted fetal heart development through mechanisms like endocrine interference and oxidative stress, highlighting mixed epidemiological findings and the need for improved exposure assessment to clarify these potential risks.

A review of human exposure to PFAS: substantial contribution from seafood
Science
30 Nov 1925 | Environ Health Prev Med
In Japan, rivers contaminated by industrial PFAS discharges have led to high levels of long-chain PFAS in seafood such as cod, clams, and shrimp, and because seafood is a dietary staple, this pathway now accounts for the majority of human PFAS intake and explains the higher blood concentrations observed in the Japanese population compared to other countries.
