We 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.

In situ oxidation of SO2 has been determined in clouds as a function of droplet size using a trace element technique during July 1998 at Whiteface Mountain, New York. The pH of the cloud water ranged from 2.8 to 4.7 with a mean of 3.4, and therefore

A tracer technique has been developed in this laboratory which allows the measurement of aqueous-phase oxidation of SO 2 in clouds. We are now extending this technique to the chemistry of nitrogen species in clouds. Using a conservative tracer such a
