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.

Objectives. To evaluate trends in blood lead levels among children in Chicago from 1968 through 1988, and to determine the impact of the changes in the Centers for Disease Control and Prevention (CDC) blood lead level of concern. Methods. We reviewed a systematic sample of blood lead screening records of the Chicago Department of Health Laboratory for high-risk children aged 6 months to 5 years. Median blood lead levels for each quarter of the years 1974 through 1988 were determined and regressed against mean air lead levels recorded at air-monitoring stations in Chicago during the same period. Results. Median blood lead levels declined from 30 µg/dL in 1968 to 12 µg/dL in 1988, and were strongly associated with declining average air lead levels (r = .8, P &lt; .001) from 1974 through 1988. A regression model using log-transformed data predicted a decline of 0.56 µg/dL in the median blood lead level with each 0.1 µg/m3 decline in the mean air lead level when the air lead level was near 1.0 µg/m3; the predicted slope was steeper at lower air lead levels. Despite the nearly 20-fold reduction in air lead levels, the median blood lead level of 12 µg/dL in 1988 indicates substantial continuing lead exposure. The CDC blood lead level of concern was lowered twice from 1968 to 1988, but due to the decline in blood lead levels, fewer than 30% of the children were above the level of concern throughout most of the study. Conclusion. Although substantial lead exposure persists in Chicago, reductions in airborne lead emissions seem to have contributed to a long-term decline in the median blood lead level of high-risk Chicago children.
