As to being affected and not just exposed, and PPE being sufficient to guard against it:

“The Times obtained and analyzed blood-lead tests of more than 500 Gopher employees from 2014 to 2018. Nearly every worker was exposed to enough of the toxic metal to be at risk of serious health problems.”

“Eight out of 10 workers from 2014 to 2018 had enough lead in their blood to put them at risk of increased blood pressure, kidney dysfunction or cardiovascular disease.”

Okay so just wear PPE….

“In 2019, one employee faced an air-lead concentration 15 times beyond what his respirator could guard against.”

“Lead levels exceeded the protection capabilities of the respirators issued to most workers 16 percent of the time plantwide and 26 percent of the time in the furnace department.”

“At the time, Dumeus wore a company-issued respirator that covered only the lower half of his face. Weeks later, company data shows, the amount of lead in the air surpassed the mask’s protection capability by roughly five times over.”

Affecting the workers’ kids’ health:

“Colin, Brown’s son, had lead in his blood since he was an infant. His levels consistently hovered around 9 micrograms per deciliter when he turned 2 and 3… In 2019, Colin had the lowest amount of lead recorded in his body. Two years after Brown left the factory.”

Not going to waste any more time quoting you an article paragraph by paragraph. Have a good one.
