“…Distance was also an important risk factor for elevated blood lead levels of children who lived less than 500 m from a battery recycling plant in Brazil compared with those who lived more than 500 m away (OR=2.54) 35) . Another study from Brazil also reported that a residential area close to a lead refinery (around 2 km) was associated with high childhood blood lead levels (OR=10.38) 36) . Our study did not include measurements of lead content in soil surrounding each house.…”

Relative Contribution of Potential Modes of Surface Dust Lead Contamination in the Homes of Boatyard Caulkers: Orrapan UNTIMANON, et al. Bureau of Occupational and EnvironmentalDiseases, Ministry of Public Health, ThailandObjectives: The aim of this study was to quantify the relative contributions to surface lead contamination of boat-caulkers' houses of three contamination modes, namely "take-home" lead from the caulker, "natural" spatial dispersal from boatyard to household and "redistribution" of accumulated lead-laden dust within the house. Methods: Boat-caulkers' houses situated in areas surrounding boat repair yards were recruited. Caulkers' houses that were located close together were divided into location-matched pairs, within which one was randomly assigned to be given a cleaning and designated a CL house, and the other was to be left uncleaned and designated a NCL house. Geographically isolated caulker's houses were randomly assigned to one of the two categories. The nearest non-boatyard worker's house (NB) was additionally recruited for each set. The surface lead loading rate (SLLR), defined as the mass of lead deposited in dust per unit area of surface per unit time, was measured over a period of 3 mo in all houses, and the data were modeled using linear mixed effects regression. Results: Adjusted values of SLLR differed only slightly between CL and NCL houses (0.96 to 1.02 times) but were between 1.65 and 2.03 times higher in CL and NCL houses than in NB houses depending on proximity to the boatyard and between 2.12 and 2.61 times higher in houses within one km of a boatyard than in more distant houses depending on category of house. Conclusions: Newly deposited dust lead likely resulted from the take-home and spatial dispersion modes. The contribution of

Abstract. Campo de Jales is a village surrounding the abandoned Jales mine. The area is heavily contaminated with heavy metals and dusts from large tailings piles as result of centuries of mining operations. The aim of this study is to investigate potential health threats associated with site contamination. The population studied comprised two groups: people living in Campo de Jales (n = 229) and a control group -people living in Vilar de Macada (n = 234). Lead and cadmium exposure and symptoms survey were carried out.The results showed a significant higher levels of blood lead and cadmium between the Campo de Jales residents (lead: 9.5 microgr/dl versus 7.7 microgr/dl; cadmium: 0.84 microgr/dl versus 0,65 microgr/dl) as well as to a higher prevalence of respiratory and irritation symptoms and great concern about his own health.In conclusion: community is the scene of long-term health problems resulting from the site environmental contamination.

Mesmo assim, são valores pontuais, em geral, e de fácil controle do ponto de vista da ingestão pela população.…”

Como resultado do crescimento da contaminação ambiental, houve um aumento do interesse relacionado ao acúmulo de metais pesados no corpo humano e seus efeitos danosos. Alguns desses metais, tal como o como chumbo, são elementos não essenciais e exercem efeitos tóxicos no sistema biológico. Apesar das medidas de controle estabelecidas por lei, intoxicações agudas e crônicas por chumbo ainda acontecem no Brasil. Algumas fontes de exposição a este metal são bem conhecidas, como por exemplo, atividades industriais como mineração, além de fábricas de reciclagem de baterias. No entanto, outras fontes, apesar de comuns, são completamente desconhecidas da população. Este artigo visa apresentar uma revisão da literatura passada e atual sobre as diversas fontes de exposição humana ao chumbo no Brasil.
