Abstract:

Sorption to particulate matter represents important physical/chemical processes that strongly influence the fate and effects of contaminant chemicals released to the aquatic environment. This file provides data on sediment properties and sorption isotherms determined for DOSS onto 12 Gulf of Mexico sediments collected from Terrebonne Bay LA examining the influence of sediment and solution properties.
