Abstract Soil lead levels were determined on and around a former battery manufacturing site. Lead concentrations ranging from 120 ppm to 5.1’ were found. The highest concentrations were found close to the factory site. When it was possible to obtain samples over a continuous depth range, it was found that lead concentration decreased with depth and that it increased above underground foundations.

Absorption Technique

A flameless atomic absorption technique, employing a tantalum strip atomizer, has been developed to determine barium and antimony in gunshot residue. Cotton swabs, wetted with 5% HNO3, are used to collect residue. Barium and antimony are released from the swabs by acid leaching or plasma ashing. Both techniques give good recoveries; the ashing technique is preferred for blood-stained swabs. The sensitivity for barium is 0.1 ng/10 µl and antimony 0.2 ng/10 µl. At nanogram levels the standard relative deviation for barium is 8.3% and for antimony 8.5%.
