Intercomparisons of Analytical Methodology and Laboratory Capabilities Between Soviet and American Laboratories—1973 to 1977

As a part of the cooperative scientific efforts between the US and the USSR on aquatic ecosystems, a comparison of analytical methodologies and laboratory capabilities was undertaken between 1973 and 1977. The samples exchanged between participating laboratories in the two countries included water samples from Lake Baikal, and standard reference samples from the U.S. Environmental Protection Agency. In general, the results from the analysis of exchanged materials show a remarkable comparability for parameters of environmental significance.
