A pilot study determining hair arsenic and lead levels in residents of a community established on a former landfill in Puerto Rico.

Arsenic (As) and lead (Pb) were determined in hair of 12 adult women and 27 children living in a soil-metal contaminated community in Puerto Rico. Average concentrations in residential soils ranged from 24 to 109 μg/g for As and from 42 to 1,585 μg/g for Pb. For hair-As, about 75% of the samples were below 0.
