Distribution of Biogeochemicals in the Sedimentary Environment of Polachira Wetland in Kollam District, Kerala

Wetlands cover approximately 5 %-8 % of the universal land area and are important part of the ecological unit The present study was undertaken in the Polachira wetland located in Kollam district, kerala. Sediment samples were collected from five different sampling stations for a period of one year from april 2013 to march 2014. The sediment samples collected were analyzed for biogeochemicals like carbohydrate, protein and lipid. The month wise data of sediment carbohydrate ranged from 0.02mg/g to 0.12mg/g during August, May and June at all stations and August (at station3& 20 and June (at station 4) respectively. The monthly data on protein fluctuated from 1mg/g during May at station I to 79.1mg/g during June at station 3. The month wise concentration of lipid varied from 0.05mg/g to 0.9mg/g during the month of January (at station 1) and July (at station 1) respectively. Among the biogeochemicals analyzed, protein was found high and the least concentration found was carbohydrate and lipid.
