DEVELOPMENT AND VALIDATION OF AN ALTERNATE ANALYTICAL AND SAMPLING PERSPECTIVE TO GREAT LAKES MASS BALANCE STUDIES - PROGRESS REPORT

Abstract

Environmental studies which include the analysis of low level anthropogenics are often limited by the analytical limits of detection {LOO) of the methodology employed. Large data bases for the Great Lakes have been accumulated over the recent past however many of the analytes (i.e. PCBs, chlorinated pesticides) have been reported as less than LOO or not detected in open lake water samples or where large sample sizes were not practicable. Data reported as such contribute little to study conclusions or model application.
