Carbon dioxide estuarine sediments

An alternative method for the determination of particulate organic carbon in marine sediments is based on oxidation with potassium persulfate followed by measurement of carbon dioxide by a Carlo Erba non-dispersive infrared analyser [152,153]. This procedure has been applied to estuarine and high-carbonate oceanic sediments, and results compared with those obtained by a high-temperature combustion method.

Biological In activated sludge, <0.1% mineralized to carbon dioxide after 5 days (Freitag et al, 1985). From the first-order biotic and abiotic rate constants of pentachlo-robenzene in estuarine water and sediment/water systems, the estimated biodegradation half-lives were 4.6-6.5 and 6.0-7.6 days, respectively (Walker et al., 1988).
