Microwave assisted digestion of atmospheric aerosol samples followed by inductively coupled plasma mass spectrometry determination of trace elements
TL;DR: The ability to determine concentrations of a very large number of elements from a single analysis will permit source apportionment of various trace pollutants and hence strategies to control the sources of air pollution as the health effects of particulate matter are increasingly recognized.

Sayantan Sarkar,Sayantan Sarkar,Tanveer Ahmed,Kamal Swami,Kamal Swami,Christopher D. Judd,A. Bari,Vincent A. Dutkiewicz,Liaquat Husain +8 more
TL;DR: In this article, the authors report measurements of 30 major and trace elements (TEs) in sediment cores from two high-altitude lakes, West Pine Pond (WPP) and Clear Pond (CP), in the Adirondack Mountains of New York State using inductively coupled plasma-mass spectrometry.

ICP-MS determination of lead isotope ratios in legal and counterfeit cigarette tobacco samples
Christopher D. Judd,Kamal Swami +1 more
TL;DR: The technique shows promise as a method for identifying counterfeit cigarettes, possibly determining the source region, and all of the genuine cigarettes and both reference materials, grown in different regions, were statistically distinct based on the measured ratios.
