Abstract Human beings could be exposed to impacts associated with heavy metals such as lead (Pb) through drinking water. The objective of this study was to evaluate quality of water consumed by kindergarten school children in Addis Ababa city, who are highly susceptible to issues related to heavy metals in water. Through conducting chemical analysis, using microwave plasma atomic emission spectrophotometry (MP-AES), the level of lead (Pb) was measured at 38 selected schools in the city. Drinking water samples were taken from three water supply sub-systems: Akaki, Legedadi, and Gefersa. Results revealed the average Pb concentration in the city was 62.37 μg/L which is significantly higher than the World Health Organization (WHO) recommended threshold value of 10 μg/L. The children's blood lead levels and exposure to Pb were also calculated using the integrated exposure uptake bio-kinetic (IEUBK) model as per USEPA guidelines. Estimated geometric mean blood lead levels (BLLs) for each school ranged from 4.4 to 13.2 μg/dL. On average, the model predicted that 20% of children in the city will have blood lead levels above the WHO recommended 10 μg/dL. The study can be considered as an unprecedented piece of work as it addresses critical issues and methods to mitigate problems caused by high concentration of Pb in water supply distribution infrastructure.

Objective. This study was designed to assess demographic and socioeconomic differences in blood lead levels (BLLs) among Mexican-American children and adolescents in the United States. Methods. We analyzed data from the Third National Health and Nutrition Examination Survey, 1988–1994, for 3,325 Mexican-American youth aged 1 to 17 years. The main study outcome measures included a continuous measure (μg/dL) of BLL and two dichotomous measures of BLL (⩾5 μg/dL and ⩾10 μg/dL). Results. The mean BLL among Mexican-American children in the United States was 3.45 μg/dL (95% confidence interval [CI] 3.07, 3.87); 20% had BLL ⩾5 μg/dL (95% CI 15%, 24%); and 4% had BLL ⩾10 μg/dL (95% CI 2%, 6%). In multivariate analyses, gender, age, generational status, home language, family income, education of head of household, age of housing, and source of drinking water were statistically significant independent predictors ( p<0.05) of having higher BLLs and of having BLL ⩾5 μg/dL, whereas age, family income, housing age, and source of drinking water were significant predictors ( p<0.05) of having BLL ⩾10 μg/dL. Conclusions. Significant differences in the risk of having elevated BLLs exist among Mexican-American youth. Those at greatest risk should be prioritized for lead screening and lead exposure abatement interventions.
