Persistent pollutants research, explained
10 open-access persistent pollutants studies, each with a flashcard deck and a quiz.
- Short-chain PFAS in US homes
Ultrashort PFAS like TFA now dominate dust, water, and serum in sampled US homes.
- Canadian pregnancy cohort maps POP levels in blood
MIREC found many POPs in maternal plasma but few in cord blood; parity, age, fish, and birthplace predicted levels.
- PFAS in Ronneby water tracks higher cholesterol
Swedish adults on PFAS-contaminated water had 7–9% higher total cholesterol and LDL, with high odds of cholesterol >6.2 mmol/L as PFOS/PFHxS rose.
- Cord-blood PFBS linked to preeclampsia in Shanghai
Among Shanghai births, higher standardized cord PFBS associated with preeclampsia (AOR 1.81) and overall hypertensive disorders of pregnancy (AOR 1.64) in a dose-response pattern.
- Ultrashort PFAS dominate Dutch drinking water
Across 18 Dutch plants, TFA and other C2–C3 PFAS dominate raw and finished water (often 49–99% of 56-PFAS mass); conventional carbon treatments often fail them, unlike longer-chain PFAS.
- Prenatal PFAS tracked 5-year child overweight risk
In 412 Scandinavian mother–child pairs, higher maternal PFAS associated with higher child BMI and triceps skinfold z-scores and with overweight/obesity at age 5, with geographic differences.
- Weathered outdoor gear sheds PFAS into the environment
Six months on a Sydney rooftop cut total fluorine in DWR fabrics and raised residual PFAAs up to 100-fold, showing outdoor textiles as PFAS sources.
- Serum PFAS mixes reveal seafood vs product exposure
Long-chain PFCAs mark seafood/whale diets, while PFHxS and N-EtFOSAA mark carpets and consumer products in children.
- PFAS in Veneto youth tracked with higher blood pressure
In 16,224 Veneto adults aged 20–39 exposed via contaminated drinking water, higher serum PFOA, PFOS, and PFHxS associated with hypertension, with the signal concentrated in men.
- PFAS-contaminated water linked to excess Veneto deaths
Residents of 30 Italian municipalities on a PFAS-contaminated aqueduct had about 3,890 extra deaths from 1985–2018, with later kidney- and testicular-cancer signals.
