“…All these chemicals are quite harmful or even fatally toxic to fish and other aquatic populations [17][18][19][20][21]. These wastes also include various toxic chemicals, acids, alkalis, dyes, detergents, pesticides and agrochemicals which greatly affect the physico-chemical properties of water bodies.…”

The present study was performed for the period of one year from January 2013 to December 2013 in order to understand the physico-chemical properties of Mahul Creek water. From the results of our study it was observed that the annual average COD level was 362.09 ppm which was far higher than the maximum tolerable level of 250 ppm set for inland surface water as well as for marine coastal water. The annual average conductivity was found to be 6122.81 µS cm -1 which was very much above the conductivity limit for inland surface water of 1000 µS cm -1 set by Central Pollution Control Board (CPCB) for propagation of fisheries. The annual average total alkalinity level was recorded as 166.25 ppm, which according to the UN Department of Technical Cooperation for Development (1985) was found to be strongly alkaline. The annual average hardness level of the creek water was found to be 2488.65 ppm which was above the limit of 300 ppm set by ISI. From the results of the present investigation it seems that the time has come to implement proper effluent water treatment techniques and enforcement of pollution control by the regulatory authority on the indiscriminate discharge of industrial wastewater into water bodies.

“…Heavy metals are thus generally defined as those having a specific density of more than 5 g/cm 3 . Heavy metals are among the most common environmental pollutants, and their occurrence in waters and biota indicate the presence of natural or anthropogenic sources.…”

“…Among the different pollutants entering the water bodies, heavy metals are of great concern. These toxic heavy metals entering the aquatic ecosystem may lead to geoaccumulation, bioaccumulation and biomagnifications; further they may also enter the food chain [2,3]. Food chain contamination by heavy metals has become a burning issue in recent years because of their potential accumulation in bio-systems through contaminated water [4][5][6][7][8].…”

in order to understand the level of toxic heavy metals in the water of Mahim Creek near Mumbai. It was observed that the annual average concentration of heavy metals like Pb, Cd, Cr, Fe, Zn, Cu and Ni and Hg was found to be 0.68, 0.28, 0.15, 0.04, 2.93, 0.64, 1.29 and 0.31 ppm respectively. The average concentrations of Hg and Pb were found to be above the maximum permissible limit of 0.01 ppm and 0.1 ppm respectively set for inland surface water by Central Pollution Control Board (CPCB) of India. The results suggest that there is a need to have such regular scientific monitoring for longer time period in order to understand the variation in level of these toxic heavy metals discharged in to the creek water. It is feared that the existing problem if ignored may increase the pollution problem of the creek due to the toxic heavy metals resulting in threat to the biological life of an aquatic ecosystem. From the results of the present investigation it seems that the time has come to move towards ecosystem specific discharge standards to maintain the health and productivity of natural resources on which the majority of human population is dependent.

The present study was performed for the period of one year from January 2013 to December 2013 in order to understand the level of toxic heavy metals in the sediments of Mahul Creek near Mumbai. The annual average concentration of heavy metals like Cr, Zn, Cu, Ni, Pb, Cd, As and Hg was found to be 277. 5, 121.7, 100.3, 63.8, 21.5, 14.6, 10.4 and 4.9 ppm respectively. It is feared that this heavy metals accumulated in the creek sediments may enter the water thereby creating threat to the biological life of an aquatic ecosystem. The results of present study indicates that the existing situation if mishandled can cause irreparable ecological harm in the long term well masked by short term economic prosperity due to extensive industrial growth.
