'Safe' levels of lead, cadmium

DALLAS, June 8 Blood levels of two metals lead and cadmium may increase the risk of peripheral artery disease even at levels currently considered safe, according to research published in today's rapid access issue of Circulation: Journal of the American Heart Association.

The general public can be exposed to lead and cadmium through cigarette smoke, in ambient air near industrial and combustion sources, in certain foods and sometimes in drinking water. Peripheral artery disease or PAD affects 8 to 12 million Americans, according to the American Heart Association. It is a condition similar to coronary artery disease and carotid artery disease. In PAD, fatty deposits build up in artery walls and reduce blood circulation, mainly in arteries to the legs and feet. In its early stages a common symptom is cramping or fatigue in the legs and buttocks during activity. Such cramping subsides when the person stands still.

In a study of 2,125 adults, those with the highest blood concentrations of lead or cadmium were almost three times more likely to develop PAD than those with the lowest levels of the two metals. Yet the highest levels were well within what is currently considered safe levels, said senior author Eliseo Guallar, M.D., DrPH, an assistant professor of epidemiology at the Johns Hopkins University Bloomberg School of Public Health in Baltimore.

Both metals are well-known toxins, Guallar said, but the levels found in the subjects "are well below the radar screen of current regulations." The new finding suggests that epidemiologists as well as basic scientists "need to think more carefully about this association and do more experiments with cadmium and lead at lower doses to determine what exposures [to the metals] might be problematic in terms of risk for cardiovascular disease."

The study includes data from adults aged 40 or older who participated in the 1999-2000 National Health and Nutrition Examina
