Case Study: It took until 1997 for the United States to conduct a comprehensive study of home lead contamination among construction workers. The study, published in the American Journal of Public Health, examined 31 children of lead-exposed workers, and compared the results of their lead testing with a control group of 19 children of unexposed workers from New Jersey, metro Philadelphia, and southeastern New York.
The study concluded that children of lead-exposed construction workers were "six times more likely to have blood lead levels over the recommended limit than children whose parents did not work in lead-related industries." The published results then reiterated some of the many effects of lead exposure, including behavioral disorders and brain damage. The risk to children is particularly high because they frequently put their hands in their mouth, thereby increasing their exposure, and because their bodily systems quickly absorb lead.
Of the workers surveyed, 50% reported changing out of work clothes prior to leaving work. In addition, 79% wore at least some street clothes at work, and nearly all (91%) washed these clothes at home. Only 18% reported always showering before leaving work.
"Parents wouldn't take their children to a dangerous workplace. It's equally important that they do not bring the hazards of the workplace home to their families," said NIOSH Director, Dr. Linda Rosenstock.
Key Takeaway: When workers inadvertently expose family members to lead, the results can be detrimental and sometimes irreversible. Follow your employer's guidelines for safe work practices and speak up if they are not enforced.
