“…9,12,[17][18][19][20][21][22] There may e two pat ways of exposure for children in the case of mine waste or mine products: one is the movement of mine wastes/products to other areas, which is unlikely given that the storage areas in Callao are well kept from the population by high fences; and the other is contact with areas near homes which may have become contaminated with mine wastes or products. In the case of Callao, this second pathway is the more likely contaminator, given that ore piles are not covered and have not been humidified to prevent fugitive dusts.…”

To determine blood lead levels in urban populations of children (n=2 510) and women (n=874) in the early postpartum in certain districts of Lima and Callao, and to correlate those levels with particular exposures. Material and Methods. Between July 1998 and January 1999 cross sectional study was conducted. The study population was selected using three sampling strategies in the government operated school system and from public pediatric and maternity hospitals at Lima and Callao, Peru. Study personnel were trained to collect finger stick blood samples with a protocol that minimizes external lead contamination. Lead determinations in blood and environmental samples were performed at the study site using portable anodic striping voltamenters. To determine the simultaneous effects of different predictors on blood lead levels, multivariate regression models were used to estimate adjusted mean differences. Results. The mean blood lead level in the children studied was 9.9 µg/dl ranging from I µg/dl to 64 µg/dl with 29% of the children displaying values greater than 10 µg/dl and 9.4% at levels greater than 20 µg/dl. Among the women, the mean was 3.5 µg/dl (SD=2.4 µg/dl), and 2.4% (n=21) Entre julio de 1998 y enero de 1999 se llevó a cabo una encuesta en el área metropolitana de Lima y en El Callao, Perú. La población de estudio fue identificada mediante tres estrategias de muestreo y con la cual se seleccionaron escuelas públicas y hospitales pediátricos y gineco-obstétricos. El personal que participó en el estudio recibió entrenamiento para la técnica de punción digital y puso especial énfasis en controlar la contaminación externa con plomo. Las determinaciones del metal en sangre y muestras ambientales se llevaron a cabo utilizando voltametría anódica. Para determinar los efectos simultá-neos de diferentes predictores sobre los niveles de plomo en sangre se usaron modelos de regresión multivariada para estimar diferencias de media y ajustadas. Resultados. Los niveles promedio de plomo en sangre fueron de 9.9 µg/dl de una variación entre 0 y 64 µg/dl. El 29 y 9.4% de los niños presentaron valores por encima de 10Determinants of blood-lead levels in children in Callao and Lima metropolitan area Rocío Espinoza, MD,(1) Mauricio Hernández-Avila, MD, MPh, ScD, (2) Juan Narciso, Eng, (1) Carmen Castañaga, MD,Shirley Moscoso, Biól,

“…In vitro assessments of bioavailability using sequential extractions and physiologically-based extraction tests and in vivo assessments in rats and rabbits have revealed that Pb salts such as Pb acetate, PbSO 4 and PbO generally are more bioavailable than PbS and Pb-containing mining ores (14,15,16). The relatively low bioavailability of metals in sulfides and mine ore have been cited as an explanation for the observation that children in mine-impacted areas have tended to have lower blood Pb than would be expected given the total Pb concentrations in their surroundings, especially compared to children in urban and smelter-impacted areas (17,18).…”

“…Several studies of former mining communities have found soil and dust lead to be strongly associated with BPbs in area children (24)(25)(26)(27)(28)(29)(30)(31)(32)(33). Other studies, however, indicate that lead from miningcontaminated soil may not always pose a risk to young children (34)(35)(36). Similarly, studies of the bioavailability of lead from miningcontaminated soils have generated conflicting results (23,33,(37)(38)(39).…”

Lead poisoning prevention requires knowledge of lead sources and of appropriate residential lead standards. Data are severely lacking on lead sources for Native American children, many of whom live in rural areas. Further, the relation of mining waste to blood lead concentrations (BPbs) of rural children is controversial. In collaboration with the eight tribes of northeastern Oklahoma, we assessed lead sources and their effects on BPbs for rural Native American and White children living in a former mining region. Venous blood lead, residential environmental (soil, dust, paint, water), and caregiver interview (e.g., hand-to-mouth behaviors, socioeconomic conditions) data were obtained from a representative sample of 245 children 1-6 years of age. BPbs ranged from 1 to 24 µg/dL. There were no ethnic differences in BPbs
