Abstract Soil lead levels were determined on and around a former battery manufacturing site. Lead concentrations ranging from 120 ppm to 5.1’ were found. The highest concentrations were found close to the factory site. When it was possible to obtain samples over a continuous depth range, it was found that lead concentration decreased with depth and that it increased above underground foundations.

<p>Lead contaminated soils occurred at lead-acid battery manufacturing and recycling sites are of great concern. Bench-scale batch experiments of stabilization treatment were conducted using twelve materials and three phosphorus-based materials, KH<sub>2</sub>PO<sub>4</sub>(KP), KH<sub>2</sub>PO<sub>4</sub>:oyster shell power = 1:1 (by mass ratio; KSP), and KH2PO4:sintered magnesia = 1:1(by mass ratio; KPM), were screened out for lead contaminated soil in an abandoned lead-acid battery factory site. The three materials had higher remediation efficiencies that led to a 92% reduction in leachable Pb and 12% reduction in bioaccessible Pb with the addition of 5% material, while the acid soluble fraction of lead decreased by 41–46%. The lead activity in the soil solution sharply decreased treated by three materials. Pb<sub>5</sub>(PO<sub>4</sub>)<sub>3</sub>Cl was the primary mineral controlling lead solubility in soil treated by KP and KSP and lead activity was related to Pb<sub>5</sub>(PO<sub>4</sub>)<sub>3</sub>OH and Pb<sub>5</sub>(PO<sub>4</sub>)<sub>3</sub>Cl in soil amended with KPM.</p>

The uptake of native and applied fractions of lead (20 and 100 μg Pb/g soil) by alfalfa and bromegrass was studied in a growth chamber experiment using three soils. The applied soil lead treatments did not affect dry matter (DM) yield but the concentration of lead in the plant tops was found to increase twofold when the amount of lead added to soil was increased fivefold (mean values for both crops 3.8 and 8.7 ppm in the 20 and 100 ppm Pb treatments, respectively). Added sulphur gave significant DM yield response in both crops on all soils but did not significantly alter the lead concentration in the aboveground DM. Lowering the temperatures and reducing the photoperiod to simulate autumn conditions resulted in a significant increase of lead concentration in plants grown on the 100 ppm Pb treatment, which was attributed to the corresponding reduction in the DM yields of the plants. High concentrations of lead (mean 132 ppm) were found in the fine roots of both crops in comparison with lead levels in main roots (mean 33 ppm). Lead extracted by various extractants from soil samples at the end of the growth chamber experiment indicated that applied lead was rapidly immobilized with the higher lead concentrations in the soil solution being found in the soil with the lowest organic matter and clay content.

The Difference

ABSTRACT Background: breast milk offers numerous advantages biological and emotional. However, in some situations, can transfer harmful elements for the health of infants. Objective: to determine lead levels in the blood and milk of mothers whose children frequent a primary mother-child health care. Methods: a cross-sectional, observational and descriptive study of 70 healthy women who were breast-feeding babies younger than six months during 01/04/2011 to 30/09/2011. Lead determination was performed by mass spectrometry with inductively coupled plasma. A linear regression model was adjusted to determine the association between lead concentrations in maternal milk and blood. The estimated values of the difference between means and their 95% confidence intervals were obtained. Results: mean lead concentration in milk was 1.462 ng/mL and blood lead concentration was 1.801 μg/dL. Conclusions: human milk is not a source of contamination for the babies in this area. However, more studies are needed in other regions of the country in view of the growing evidence of foci of lead contamination, which may represent an occult risk for the population.
