Abstract
The electrothermal atomic absorption spectrophotometric determination of Mn and Pb in wet, dry and total deposition collected at American Samoa is hindered by interferences due to the dilute sea-spray matrix. Matrix modification procedures permit direct analysis below 1 ng ml−1 for each trace metal. The median monthly deposition of Mn is 5.8, 5.0, and 10.0 ng cm−2, and for Pb 9.5, 1.4, and 10.6 ng cm−2 for wet, dry and total collections, respectively. Preliminary data suggest effective sampling using these methods at this remote site.
