Pb isotopic composition of airborne particulate material from France and the southern United Kingdom: implications for Pb pollution sources in urban areas

Article Abstract:

The lead (Pb) isotopic compositions of airborne particulate matter reported in France and the UK underscore their importance in the European Union's (EU) efforts to protect the environment. The ratios of (super206)Pb and (super207)Pb in gasoline were found to range from 1.061 to 1.094 with France and the UK having an average value of 1.084 and 1.067, respectively. The significance of gasoline-derived Pb as a tool in anthropogenic processes has decreased following the recent EU rule that limits concentrations of Pb in gasoline.

Leaching of Cd and Pb from a polluted soil during the percolation of EDTA: laboratory column experiments modeled with a non equilibrium solubilization step

Article Abstract:

The mobilization and movement of Cd and Pb from a polluted soil are examined with both experimental column percolations of ethylenediaminetetraacetic acid (EDTA) and mathematical modeling. Results reveal that only a few pulse injection experiments are required to understand the transport and complexation and solubilization processes. The simple transport model has removed the need to determine the chelate concentration at the outlet of the column to obtain the complexation rate over long elution times.

Measuring Pb Bioavailability from Household Dusts Using an in Vitro Model

Article Abstract:

Researchers examined an in vitro test to determine its effectiveness as an indicator of blood Pb levels in infants relative to Port Pirie, Australia, a city with a 100+ year history of smelting and refining. Tables and figures accompany the article.
