PEBE, Godofredo; VILLA, Hugo; ESCAT, Luis  e  CERVANTES, Gonzalo. Blood lead levels in newborns from La Oroya, 2004-2005. Rev. perú. med. exp. salud publica [online]. 2008, vol.25, n.4, pp.355-360. ISSN 1726-4634.

Objective. To determine blood lead levels in newborns less than 12-hours of life, in La Oroya. Material and methods. A descriptive, cross-sectional, and prospective study performed between June 2004 to June 2005 in a sample consisting in newborns in La Oroya. A questionnaire was administered to pregnant women and lead levels were determined in a sample of venous blood (2 mL) using atomic absorption spectrophotometry with an air-acetylene flame. Values are expressed ad micrograms of lead per deciliter of blood (ug/dL). Results. 93 newborns were assessed, average blood lead contents was 8.84 μg/dL (SD: 0.57). 70 newborns (75.3%) had blood lead levels between 6 and 10 μg/dL, and 23 (24.7%) had more than 10 μg/dL. Newborns from mothers living in La Oroya Nueva (the new city) have blood lead levels lower than those from mothers living in La Oroya Vieja (the old city) (p= 0.002). Conclusions. Newborns in La Oroya have high blood lead levels, so it is necessary to initiate prevention programs in pregnant women in order to prevent deleterious health outcomes in newborns.
