For how we live.
Carbon filters and ion exchange concentrate PFAS rather than breaking it down, which turns treated water into a residual-waste problem. A new review puts numbers on what destruction would cost in energy.
The 2024 US drinking water limits are the reference point for almost every PFAS conversation. Four of the six regulated substances are now the subject of a proposed rescission.
Thirty-two thousand mid-Ohio Valley residents with high PFOA exposure were tracked through 2021. Of 22 causes of death examined, one trend was significant and the authors themselves urge caution.
A meta-analysis of 14 studies and 7,465 men found little for the conventional semen parameters, and something more consistent for sperm DNA fragmentation.
A Copenhagen team has just published the protocol for the first study designed to test whether reducing PFAS exposure changes anything. That it is still a protocol tells you where the evidence stands.
Eight primary schools in Porto and 40 homes in the Faroe Islands were sampled by different teams asking the same question: how much of a person's PFAS exposure never touches food or water.
Two cohorts published ten days apart. One found the PFAS mixture more than doubling the odds of hypertension at 24 to 28 weeks; the other found lower birth weight, but only in female infants.
One found PFAS mixtures associated with lower kidney filtration, with blood lipids mediating much of it. The other found the lipid association weaker in people with healthier habits.
A 2,836-pair analysis of the ECHO cohort found one of four compounds associated with parent-reported sleep problems. A Shanghai study of bone density found opposite directions in girls and boys.
A 1,224-person biomonitoring study found four compounds only in firefighter serum. A separate 65-person pilot in Texas asked whether that matters for cognition, and got a partial answer.
A 22-country survey of landfill leachate and a 39-year Chinese emissions inventory point at the same conclusion — production controls have shifted the problem to waste streams.
