Lead poisoning and exposure can leave layers of uncertainty in the wake. My twin babies were exposed to lead at our previous home in Ohio. One of them experienced acute toxicity which can potentially disrupt her cognitively for life. We were poor renters, so in hindsight and in lew of Flint, it is not suprising.
To your point about the visibility of toxicity, my familial experience points to the stigma attached to percieving certain populations as risky. For instance, in my hometown, because lead exposure was so often tied to poverty, being seen at the lead clinic was stigmatized-in with going on SNAP and going to the pediatric clinic for basic care. Exposure became another way of being made legibly marginal.
