People whose blood has a concentration of lead that is high but that is still considered safe have a higher risk of death from many causes than people with a low concentration, a new study shows.
The 14 000 people in the study, which was published online on 18 September in Circulation (http://circ.ahajournals.org, doi:10.1161/circulationaha.106.628321), were recruited from 1988 to 1994 and followed for 12 years. Compared with participants whose blood lead concentration was <0.09 micromol/l, participants whose blood lead concentration was between 0.17 micromol/l and 0.48 micromol/l had a 25% higher risk of death from any cause, a 55% higher risk of death from cardiovascular disease, an …
