Blood lead levels were inversely related to the distance to the smelter.


RISK ASSESSMENT OF LEAD POISONING IN THE SMELTER'S ADJOINING AREA IN CIUDAD JUAREZ; CHIH: MXICO. DAVID REYES, SANIN L, ROMIEU I, DÍAZ-BARRIGA F, ORNELAS-HICKS M, LACASAÑA M. Universidad Autónoma de Ciudad Juárez. EMail: iromieu@insp3.insp.mx

"We carried out an assessment of the residual risk of lead poisoning in the area close to the ASARCO smelting plant in Anapra where remediation occurred in 1973, and determined major predictors of blood lead levels in mothers and children. ...."

"Their blood lead levels ranged from 3.5 - 23.6 μg/dL with an arithmetic mean of 7.35 μg/dL (s ± 3.50), and a percentage of 30% = 10 μg/dL. Blood lead levels were inversely related to the distance to the smelter.
