Mabel St., Tucson, AZ 85721, USA.AbstractChildren living near contaminated mining waste areas may have high exposures to metals from the environment. This study investigates whether exposure to arsenic and lead is higher in children in a community near a legacy mine and smelter site in Arizona compared to children in other parts of the United States and the relationship of that exposure to the site. Arsenic and lead were measured in residential soil, house dust, tap water, urine, and toenail samples from 70 children in 34 households up to 7 miles from the site. Soil and house dust were sieved, digested, and analyzed via ICP-MS. Tap water and urine were analyzed without digestion, while toenails were washed, digested and analyzed. Blood lead was analyzed by an independent, certified laboratory. Spearman correlation coefficients were calculated between each environmental media and urine and toenails for arsenic and lead. Geometric mean arsenic (standard deviation) concentrations for each matrix were: 22.1 (2.59) ppm and 12.4 (2.27)ppm for soil and house dust (

  The University of Arizona Superfund Research Program has been working at the Iron King Mine and Humboldt Smelter Superfund Site since its designation in 2008. In response to community concerns and research interests, we launched the Metals Exposure Study in Homes to better understand environmental exposures of local children by measuring concentrations of metals in biological and environmental samples. Participants received the results and a guide to interpretation. Through community engagement, including informational meetings and formation of a community advisory board, we sought to empower residents with environmental health knowledge and ultimately reduce metals exposures in the community.

  More info

  The Iron King Mine and Humboldt Smelter Superfund Site is located in northern Arizona and is characterized by piles of minetailings and smelter ash adjacent to the Town of Dewey-Humboldt, AZ (2010 population: 3,984). Residential exposure to metals in yard soil deposited via windblown dust from the Site is a concern because of the Site’s immediate proximity to homes and climate conditions, which may blow dust from the tailings and into Town. Arsenic concentrations over 1,000 mg/kg arecommon on the Site, with levels up to 4,400 mg/kg. Exposure to arsenic can increase the risk of developing lung, skin, bladder, breast, prostate, kidney, and liver cancer as well as digestive tract and dermal health issues. Adults and kids may ingest arsenic in soil blown in from the Site whileplaying or working in the yard. Also, children may be at higher risk ofaccidentally ingesting soil because of behaviors like playing outside on the ground and the tendency to taste items they find that may be coated with soil or dust.
