PCB sources and degradation in sediments of Ashtabula River, Ohio, USA, determined from receptor models

The PCB pollution in Ashtabula River sediments was evaluated using a factor analysis (FA) model with non-negative constraints, and a chemical mass balance (CMB) model. The FA model identified Aroclor 1248 as the major PCB source, and also a congener pattern significantly different from that of any A...
