Evaluating the effect of age and area of residence in the metal and metalloid contents in human hair and urban topsoils.

摘要: Monitoring the levels of trace elements in hair can allow estimating effects geographical location and also provide a notion metal body burden. However, use human is controversial due to different confounding factors that could affect presence hair. As result, comprehensive monitoring study was performed Alcala de Henares, one major cities Madrid region, Spain. Trace have been monitored urban topsoils two well-defined healthy groups population: children (6–9 years) adolescents (13–16 years). The city divided into four areas or zones with characteristics assess possible effect area residence age Al, As, Be, Cd, Cr, Cu, Hg, Mn, Pb, Sn, Ti, Tl Zn soils There no current hypothesis explains distribution Ni, Sn Ti found these soils, maybe because receive high disturbance, there are many involved. most significantly higher population, except for Zn. This be attributed mainly dietary habits. Other influencing content such as environmental would had minimal population here studied. Finally, none studied were correlated measured public parks exception Pb adolescent participants.
