Comment on "Off-Site Forensic Determination of Airborne Elemental Emissions by Multi-Media Analysis: A Case Study at Two Secondary Lead Smelters." (response to D.E. Kimbrough and I.H. Suffet, Environmental Science & Technology, vol. 29, no. 9, p. 2217, 1995)
Article Abstract:
An analysis of lead, arsenic and antimony concentrations in soil samples taken near a smelter in West Dallas, TX, was conducted to determine if the arsenic and antimony came from the smelter or from another source. The study was similar to a case study at two secondary California lead smelters claiming that airborne emissions from smelters reveal highly correlated concentrations of lead, arsenic, antimony and cadmium which form characteristic ratios. Results of the analysis affirm the conclusion that examination of concentration ratios and correlations among the compounds is a reliable method for confirming the presence of airborne emissions from a secondary lead smelter.

Mechanisms controlling the mobility of lead in the spodosols of a northern hardwood forest ecosystem
Article Abstract:
Ultrafiltration and resin chromatography techniques were used to measure lead speciation in soil solutions at the Hubbard Brook Experimental Forest. The study seeks to assess the extent of association of mobile lead (Pb) with colloidal sized materials and organically complexed forms believed to cause the mobility of Pb in soil. It is hypothesized that the two relatively independent processes of adsorption of ionic Pb and adsorption of organic colloids with associated colloidal Pb are responsible for rescavenging Pb released from the surface organic layer in the mineral soil.

Evidence of complete retention of atmospheric lead in the soils of northern hardwood forested ecosystems
Article Abstract:
Soil samples at Hubbard Brook Experimental Forest in New Hampshire were analyzed to determine if atmospheric lead is retained after being deposited in forested ecosystems. The results showed that lead levels in streams and seeps were generally under 10 parts per trillion despite the large amount of lead leached out of the forest floor layer. This indicates that mineral soil functions as a net sink for atmospheric lead.
