High Lead Exposure and Auditory Sensory-Neural Function in Andean Children

High Lead Exposure and Auditory Sensory-Neural Function in Andean Children

We investigated blood lead (B-Pb) and mercury (B-Hg) levels and auditory sensory-neural function in 62 Andean school children living in a Pb-contaminated area of Ecuador and 14 children in a neighboring gold mining area with no known Pb exposure. The median B-Pb level for 62 children in the Pb-expos...

Zusammenfassung:We investigated blood lead (B-Pb) and mercury (B-Hg) levels and auditory sensory-neural function in 62 Andean school children living in a Pb-contaminated area of Ecuador and 14 children in a neighboring gold mining area with no known Pb exposure. The median B-Pb level for 62 children in the Pb-exposed group was 52.6 μg/dl (range 9.9-110.0 μg/dl) compared with 6.4 μg/dl (range 3.9-12.0 μg/dl) for the children in the non-Pb exposed group; the differences were statistically significant (p
