Women resident in an area heavily contaminated by spoil from old lead mining have blood lead concentrations that are about 50% higher (p less than 0.001) than those of women living in a "control" area some distance away. Blood lead concentrations were related to the consumption of home grown produce. Those with the highest consumptions had blood lead concentrations that were 28% higher (p less than 0.001) than those of women who consumed no locally grown vegetables. Nevertheless, in the total population in the area this effect seemed likely to account for only about 5% of the population mean blood lead concentration. The data suggested that an increase in soil lead of 1000 micrograms/g is associated with an increase in blood lead of about 0.20 microM/1 (4.2 micrograms/dl).
