摘要：Organic carbon (OC) can be classified into three main categories: labile, semi labile and refractory. The area of research is primarily focused on the labile organic carbon (LOC) as it is considered highly reactive indicator of green house gas (GHG) emission from reservoirs and lakes. The CO2or CH4release fro m sediment OC depends on its source and temperature o f the reservoirs. The several analytical methods are available to determine and evaluate LOC based o n physical, chemical and biochemical methods. A review of the advantages and disadvantages of each technique has indicated that none of the methods can be used to determine LOC precisely either because a part of the LOC is not involved or its further characterization is apparently missing. The approach is an omnipotent tool for the measurement of LO C. The present paper reviews the methodologies for estimating LO C and other types of organic carbon like LOC which plays crucial role in estimating the GHG emissions from reservoirs /lakes and lays the emphasis only on LOC (DOC, DIC and POC) due to its rapid degradation for the release of GHG co mpared to other .C. types
