Abstract

The early and continuing research on atmospheric chemistry, particularly precipitation chemistry, necessitated the adaptation of existing methods for analysis of the complex precipitation water matrix, and the development of sample collection, handling, and storage procedures. Presently available instrumental techniques used for inorganic analysis are sufficiently refined to provide accurate determinations down to ..mu..g l/sup -1/ levels in most cases. Because of the low ionic concentrations (approx. 20 mg l/sup -1/) routinely encountered in precipitation samples, however, biases introduced in handling and storage procedures can become the determining factors affecting reliable data acquisition and interpretation. The procedures presented in this document were developed during the last ten years of precipitation chemistry research. In most cases they represent modified methods adapted specifically to meet the special requirements necessary for trace analysis of inorganic constituents in rainwater samples. All procedures have been rigorously evaluated to ensure that all aspects of collection, handling, and analysis are mutually compatible. Detailed methodologies are outlined from all the major ions normally encountered in precipitation samples in addition to many metals also found in trace amounts in rainwater. They include NH/sub 4/, Cd, Cl/sup -/, Pb, NO/sub 3//sup -/, SO/sub 4//sup 2 -/, Sr, and Zn.
