Because in past times, there was not the sophistication of diagnosis for such things as low level lead
is not instantly "fatal". Fatal doses are rare. Generally speaking it is a cumulative, slow situation of subtle deterioration. The effects are slow to show up and can also be mis-attributed to other problems. By the time a person is approaching a fatal dose, they have long had overt and dramatic symptoms.
In some cases in some eras, lead
poisioniong was simply "ignored" as a "cost of living"
It is only relatively recently that we have become aware of the damage that even low levels of lead
in the body can do. Particualrly to kids.
