BURKHARD, L. P., P. M. COOK, AND M. T. LUKASEWYCZ. Organic Carbon--water Concentration Quotients (IIsocS and [pi]pocS): Measuring Apparent Chemical Disequilibria and Exploring the Impact of Black Carbon in Lake Michigan. ENVIRONMENTAL SCIENCE AND TECHNOLOGY. John Wiley & Sons, Ltd., Indianapolis, IN, 42:3615-3621, (2008).
Impact/Purpose:
This report measures IIsocs and investigates the impact of black carbon upon the sediment-water concentration quotient...Disequilibrium can be inferred through use of the traditional TOC equals biogenic carbon approach. The recent and developing research on black carbon and other CGs provides, at a minimum, an important advancement in understanding why apparent disequilibria can exceed biogenic carbon based expectations.
Description:
When black carbon (bc) and biologically derived organic carbon (bioc) phases are present in sediments or suspended particulates, both forms of carbon act additively to sorb organic chemicals but the bc phase has more sorption capacity per unit mass. . . .
