FLINT, Mich. — Words are toxic, too. Labeling Flint’s children as “poisoned,” as many journalists and activists have done since the city’s water was found to be contaminated with lead in 2014, unjustly stigmatizes their generation.

Let’s be clear. It’s unacceptable that any child was exposed to drinking water with elevated lead concentrations. We know that lead is a powerful neurotoxicant, that there is no safe level, that the very young are particularly vulnerable and that long-term exposure to low to moderate levels of lead is associated with decreased I.Q.s and other cognitive and behavioral problems, including criminal behavior.

But there is no reason to expect that what happened for a year and a half in Flint will inevitably lead to such effects. The casual use of the word “poisoned,” which suggests that the affected children are irreparably brain-damaged, is grossly inaccurate. In a city that already battles high poverty and crime rates, this is particularly problematic.

In the mid-1970s, the average American child under the age of 5 had a blood lead level of 14 micrograms per deciliter. The good news is that by 2014 it had fallen dramatically, to 0.84 micrograms per deciliter, largely because of the banning of lead in paint and the phaseout of lead in gasoline, among other measures.
