Over a million people in Peru may be exposed to lead (Pb) due to past or present mining‐related activities; however, neither soil Pb nor blood Pb are routinely monitored throughout the country. Because little is known about Pb contamination in smaller mining‐impacted towns, soil Pb was mapped in four such towns with a portable X‐ray fluorescence analyzer in 2015. The roadside mapping delineated hotspots of highly contaminated soil (1,000–6,000 mg/kg Pb) in two of the towns. The local health department, provided with a LeadCare II analyzer, then measured blood‐Pb levels >5 in 65% and >10 μg/dL in 15% of children (n = 200) up to 6 years of age in these same four communities. There were no clear relations between child blood‐Pb levels and Pb levels in soil samples collected inside (n = 50) or outside the home (n = 50). Increased child blood Pb was associated with decreased level of cleanliness of parent clothing (n = 136) and shoes (n = 138), linking a possible behavioral factor for transferring contaminated soil and dust to children. In order to explore individual exposure and variations in soil Pb, 10 parents of children with blood Pb >10 μg/dL and 10 parents of children with blood Pb |
