Journal Title: International journal of Emerging Trends in Science and Technology - Year 2016, Vol 3, Issue 1
Abstract
In the present study an attempt has been made on trace element analysis on various ponds connected to Neyyar river basin in Thiruvananthapuram District of Kerala. The study was carried out for two years i.e. January 2012 to December 2013. For the study period ten sites were selected and was conducted to determine the seasonal changes of trace elements (Cu, Cd, Cr, Fe, Mn, Zn, Co and Pb). The concentration of Cadmium in pond ecosystem ranges from 0.001 mg/l to 0.028 mg/l. The trace element concentrations are below the permissible limit in all ponds except Cadmium. The concentration of cadmium is higher in one pond (Thavalayilakulam). Co was not found in any of the ponds during the study period. The trace elements were determined by atomic Absorption Spectrophotometer, Thermo ICE-3500 series. All the data were analysed statically using one-way ANOVA to investigate the seasonal significant relationship in the ponds.
