9. Concept of KOC and Partitioning

This chapter focuses on the partitioning behavior of chemicals in relation to organic carbon and their implications in environmental science. It examines the significance of the partition coefficient KOC as a normalized measure of chemical interaction with organic matter compared to water. The discussion extends to the concepts of bioaccumulation and the octanol-water partition coefficient KOW, linking physical chemistry principles to practical environmental and health considerations.
