Drinking water in plastic bottles contains countless particles too small to see. New research finds that people who drink water from them on a daily basis ingest far more microplastics than those who don’t.
The link between tire and brake dust to ASD isn’t a concrete causation yet. The papers do show a correlation, yes, but that isn’t the same as definitive proof of causation.
For example, areas with higher tire/brake dust will have higher vehicle traffic, so it might be some other pollutant vehicles produce.
Most public health policy (and hell, most of medicine) is based on correlation. Causation isn’t generally needed and sometimes it’s not even possible to prove.
Sure. But they were responding to the claim that “we know tires and break dust is a cause of autism”. Not “there seems to be a correlation, so maybe we should err on the side of abundant caution and treat it as if it’s causal when drafting public policy.” The correction was warranted.
