Microplastics in salt, seafood and tea bags: do the doses matter?
Particles turn up across the food supply, and plastic tea bags shed billions per cup. The counts are real; whether these amounts affect health is unestablished.
For how we live.
Particles turn up across the food supply, and plastic tea bags shed billions per cup. The counts are real; whether these amounts affect health is unestablished.
A 2024 imaging method found roughly a quarter-million plastic particles per litre of bottled water, most of them nanoplastics — far more than older counts, and mostly unstudied.
In 5,520 children across 34 states, prenatal exposure to regulated public-water fluoride showed no association with emotional or behavioural problems overall — with one caveat in a secondary model.
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.
Most childhood lead exposure traces to deteriorating paint in pre-1978 housing and the dust it sheds. The damage to a child's developing brain is steepest at the lowest measured levels.
