    ASSESSMENT OF PHYSICOCHEMICAL CHARACTERISTICS AND THE LEVEL OF NUTRIENT CONTENTS AS WELL AS HEAVY METAL IONS IN WATERS OF THREE LAKES AT COIMBATORE, TAMIL NADU, INDIA
    (Journal of Materials and Environmental Science, 2016-02-26) Manikandan, R; Ezhili, N; Muthulakshmiandal, N; Paulo J. C, Favas; Venkatachalam, P
    Lake water quality degradation and heavy metals pollution have been serious environmental threats for last decades, especially in those fresh water lakes situated in the vicinity of the cities and human habitations. The present study aimed to investigate the physicochemical parameters, level of nutrient contents and heavy metals to determine the water quality of Ukkadam, Kuruchi and Singanallur Lakes. All the physicochemical parameters except dissolved oxygen, sulphate, silicate and nitrate values were found above the prescribed limit as recommended by WHO (2011) and BIS (2003) drinking water quality. The concentrations of Ca, Cr, Cu, Fe, Niand Pb in waters of the selected three lakes ranged from 0.014 – 0.038, 0.145 – 0.063, 0.025 – 0.552, 0.100 – 3.460, 0.028 – 0.117 and 0.463 – 2.172 mg/L respectively. The concentrations of heavy metals except Cu were found to be higher than the permeable dose. This investigation revealed that the water in these lakes is partially contaminated with high level of heavy metals. It is recommended that proper implementation of new wetland waste management system and constant monitoring is urgently required to maintain good water quality in these lakes for future generation.

    A STUDY ON THE BIOACCUMULATION AND SCREENING OF TOXIC METAL IONS IN EFFLUENTS, FODDER AND MILK SAMPLES COLLECTED FROM ERODE, TIRUPUR, COIMBATORE DISTRICTS
    (Research Journal of Chemistry and Environment, 2020) Anuradha, J; Gayathri, N S; Muthulakshmiandal, N
    Water pollution is a serious problem of concern due to the potential health impacts of bioaccumulation in the food chain. Based on this fact, a field study is conducted in the areas of three major polluting industries viz. dyeing, tannery and plating located at Coimbatore, Tirupur and Erode pertaining to ground water table contamination due to heavy metals from industrial discharges. The outcome of the field study formed a baseline to investigate the accumulation of toxic metal ions: Cd, Cu, Zn, Pb, Fe, Co, Cr, Mn and Ni in the effluent, fodder and milk samples. A marked extremity of pollution is recorded against lead and chromium concentrations in comparison to WHO permissible limits for effluents, diminishing reflecting in the inherent increase of 7 and 5 fold times for fodder/ milk samples. Also, reclamation studies are performed using naturally occurring eco-friendly materials to minimize the extent of pollution in all the chosen samples. The analysis and assessment of the results conclude that thus the materials possess excellent metal chelating ability and serve as better choice in the heavy metal bioaccumulation by treating the effluents even before being discharged into the soil environment.
