“…Between 100 and 300 mg/kg soil-Pb, the blood-Pb exposure response to soil-Pb flattens out. Above 300 mg/kg, the slope of the bloodPb exposure response to soil-Pb is 0.32 mg/dL per 100 mg/kg (Mielke et al, 2007a). Johnson and Bretsch (2002) independently corroborated children's exposure responses; when comparing New Orleans results with Syracuse, New York, results, they noted a remarkably similar blood-Pb response to Pb in soil.…”

“…The current US Centres for Disease Control and Prevention (CDCP) blood-Pb guideline is !10 mg/dL (Healthy People, 2010). The exposure response of children's blood-Pb to soil-Pb has undergone scrutiny in New Orleans and all of the results show remarkably robust trends (Mielke et al, 1997(Mielke et al, , 2007a. Below a median of 100 mg/kg Pb in soil, the median blood-Pb response is steep (see below Section 10.4) with an overall increase of 1.4 mg/dL per 100 mg/kg.…”

“…Soils in urbanized areas, especially inner cities, contain unwanted toxins, such as Pb, that affect children (Mielke et al, 2007a).

“…Other studies report similar results based on soil survey data without considering other sources of lead exposure. For instance, Mielke et al (2007) used soil lead data of a survey completed in New Orleans in 2000. The soil samples were stratified by 1990 census tracts.…”

Blood lead levels in children in the USA have dropped dramatically since lead in food, air and drinking water was reduced. In inner cities and older residential areas, increased lead exposure may still be a problem because of dilapidated housing with high lead paint levels. In these areas, at mining sites and around smelters lead levels in soil may be very high. A review of many studies indicates that lead in soil or mine tailings does not make a meaningful contribution to lead absorption by children. The contribution of lead in soil to overall exposure, if any, lies within the variation of the analytical method for blood lead measurements. The results of exposure studies in the pediatric population reviewed in this article do not support exposure predictions for children under 6 years of age based on the US EPA Integrated Exposure Uptake Biokinetic Model (using default parameters or using results obtained with in vitro digestion models). They also do not support predictions based on the percent of solubility of lead in soil (accessibility studies).

“…The severity of soil pollution depends on multiple factors including weather, topography, and the specific industrial production 5,6,7 . Studies have shown that blood lead levels in children are related to soil lead concentration 8,9,10 . For each 1,000ppm of lead concentration in the soil, the blood lead level typically increases 3-7μg/dL 4,11 .…”

Proximity of residence to an old mineral storage site in Chile and blood lead levels in children

et al. 2016

Evidence suggests that an old mineral storage site removed in 1998 due to high lead content, remains as a source of exposure in the city of Antofagasta, Chile. The aim was to determine the association between blood lead levels in children and the residential proximity to the old mineral storage site. A cross sectional study was conducted with 185 children aged 7 to 16 years. The outcome variable was blood lead levels measured in 2005. The exposure variable was the distance between the current residence and the old mineral storage site. The distance was measured in meters by Geographic Information System (GIS). The median blood lead level in 2005 was 3.3μg/dL (interquartile range ‒ IQR: 2.0-4.3). A significant inverse association was found between the residential distance to the old mineral storage site and the blood lead levels in children, after adjusting by confounders (β: -0.04; 95%CI: -0.09; -0.01). This result suggests that the old mineral storage site continues to be a source of lead exposure for the children living nearby.
