Also, here's a nice column Slate ran a couple years ago explaining the dangers of lead. Of course, anything that might impact a child's health is particularly sensitive territory, hence the debacle Mattel currently finds itself in. But, according to the Slate piece, there's some science behind Mattel's pickle.
To get a sense of the potential risks posed by lead, as well as the debate that informs reactions to even relatively low-level exposures like this one, you first need to know one thing: It is, basically, all about children (and pregnant or breast-feeding women). Experts, it seems, don't worry much about the effect of low-level lead exposure on adults.
Enough said. Recent Mattel coverage.
