RAMIREZ, Augusto V.; CAM PAUCAR, Juan and MEDINA, José M.. Blood lead levels in the inhabitants of four Peruvian localities. Rev Panam Salud Publica [online]. 1997, vol.1, n.5, pp. 344-348. ISSN 1020-4989. http://dx.doi.org/10.1590/S1020-49891997000500002.
During 1994 and 1995, a cross-sectional study was carried out to investigate the concentrations of lead in the blood of inhabitants of four Peruvian cities (Lima, Huancayo, La Oroya, and Yaupi) with different population densities and degrees of industrial development. In a random sample of 180 men and 180 women without occupational exposure to lead, blood lead levels were measured by the atomic absorption method with a Perkin Elmer 603 spectrophotometer without a graphite oven. The results revealed blood lead concentrations of 269 ± 63 micrograms per liter (mg/L) in Lima, 224 ± 47 (mg/L in Huancayo; 348 ± 40 mg/L in La Oroya, and 140 ± 27 mg/L in Yaupi. It was concluded that blood lead levels in the inhabitants of these cities were related to the degree of industrialization and the population density of each locality.
