This study was conducted to relate blood lead levels in infants to changes in lead emissions in Santiago, Chile, a heavily polluted setting where leaded gasoline began to be replaced with unleaded gasoline in 1993. Over an 18-mo period, 422 infants had blood lead levels, cotinine, and iron status determined at 12 mo. Blood lead levels fell at an average rate of 0.5 μ/dl every 2 mo, from 8.3 to 5.9 μ/dl, as the city experienced a net fall of 30% in the quantity of leaded gasoline sold. Time… 

Blood Lead Levels in Andean Infants and Young Children in Ecuador: An International Comparison

It is indicated that infants and young children exposed to Pb from Pb glazing of ceramics in Andean Ecuadorian villages exhibit greater potential metal-mediated poisoning than children of similar ages in Asia, Europe, other Latin American countries, and the United States.

Blood lead concentrations in children from Zajaca are highest, and blood lead levels of exposed children to those of partially exposed and non-exposed children are compared and correlate values of BLLs from two consecutive sampling series in 2012 and 2013 are correlated.

[Comparison of children's blood lead levels in Shanghai before and after the introduction of lead free gasoline].

The introduction of lead free gasoline could decrease children's blood lead levels in Shanghai, however, the magnitude of decrease is not as great as expected, suggesting that more environmental interventions, such as industry emission control, are needed to prevent childhood lead poisoning.

Infants living in an urban area and exposed to increased atmospheric lead levels have higher blood lead levels than infants living in a rural area.

Decline in blood lead in Ontario children correlated to decreasing consumption of leaded gasoline, 1983-1992.

The blood lead concentrations in Ontario children has declined in both rural and urban areas over the past decade, this decline coinciding with the complete phasing out of lead in gasoline in 1990.

Monitoring of blood lead levels in Hungary.

Monitoring of blood lead levels (BLL) in children in Hungary started in Hungary only in the 80's, and recently a representative survey in preschool children showed a mean BLL of 5.7 micrograms/dl, and only 4.7% of the data exceeded the limit of 10 microgramS/dl.
