| Summary: | (513C) as tracers of biodegradation of petroleum in 813C of respired C02 as an indicator of the organic matter affected the discrimination between C02 and substrate. An investigation into the use of stable carbon isotopes being degraded. The precision of this procedure in biometer being utilized. C02 production was less than 2.2 %. for all but one substrate estuarine grasses that range from -1 6 to -1 0 %. or estuarine sediments was performed. This technique uses the flasks was determined to be ︢0.8 %. over an eight day isotope discrimination between C02 and substrate during peak laboratory work indicated that stable carbon isotopes of of residuals was performed for experiments with more than one Parallel 14C-CO2 experiments and gas chromatography analysis period. This precision is sufficient to distinguish between petroleum hydrocarbons, which have a typical ratio from -30 phytoplankton which have a ratio around -21.7%.. The carbon possible substrate. Results from these analyses confirmed respired C02 are useful in determining the substrate that is results from the 513C of the respired C02. Findings from the tested. Experiments in which the C:N ratio varied, indicated that substrate availability, not nitrogen availability, to -26 %. depending on the petroleum, and for example, |
