There's an interesting 'The Studies Show' episode on the link between lead and IQ [0]. The gist being that at low level exposure there's a lot of uncertainty about whether there is any association with adverse outcomes, because any effect is effectively swamped by other effects. I thought it was relevant/interesting because the paper uses the EPA guidance maximum contaminant level goal of 0, while for example talking about low and mild exposure in the same context as chronic kidney disease.
