ABSTRACT
Evaluates the polychlorinated biphenyl pollution (PCBs) in Ohio's Ashtabula River sediments using a factor analysis (FA) model with non-negative constraints and a chemical balance model. Effectiveness of the factor analysis model in source identification and pattern recognition in PCB contaminated sediments; Failure of the CMB model to reproduce the sample congener profiles; Indications of significant alterations in PCBs.
