    Opis:
    The Dombivli city near Mumbai has rapid industrialized. However the improper environmental planning has resulted in discharge of industrial waste effluents from the industrial belt into the Ulhas River. These wastes from these industries include various toxic heavy metals which subsequently accumulate in the sediments of Ulhas River. This day by day increasing tremendous pollution load has provoked us to carry the systematic and detailed study of heavy metal content in the sediment samples collected along the Ulhas River along the Dombivli City, near Mumbai. The study was conducted in year 2012 and 2013. The study was carried out in along the banks of Ulhas River near the discharge of effluents from Dombivli Industrial belt Phase I and Phase II. Accordingly the sampling points were identified. The analysis for the majority of the toxic heavy metals like Cadmium (Cd), Copper (Cu), Nickel (Ni), Chromium (Cr), Cobalt (Co), Iron (Fe), Lead (Pb), Mercury (Hg), Arsenic (As) and Zinc (Zn), in sediment samples was done. From the results of our study, it can be concluded that there is a need of systematic and regular monitoring of pollution level along the Ulhas River so as to generate the data on accumulation of heavy metals in the river sediments which will further help in improving the industrial waste treatment technology adopted along the Dombivali industrial belt. It is expected that such scientific studies will help to gauge the extent of pollution in order to avoid long term irreparable damage to the ecosystem.

    Opis:
    The paper deals with monitoring of pollution arising due to metallurgical industries located along the Dombivali industrial belt of Mumbai, India. The study was carried for the period of one year from June, 2012 to May, 2013 to study the level of toxic heavy metals and the physico-chemical properties of waste water effluents discharged from the above industries. The concentration levels of Cu, Ni, Cr, Pb, Fe and Zn were found to be maximum of 41.00, 1.47, 5.97, 2.55, 46.86 and 12.97 ppm respectively during winter and summer seasons starting from December to May. The pH value was found to be maximum of 10.30 in the month of February, while the conductivity was found to be maximum of 25067 μmhos/cm in the month of July. The majority of physco-chemical parameters like salinity, chloride content, and total solids (TS) were observed to be maximum in the month of June having values of 6.32, 2411 and 20738 ppm respectively. The high cyanide (0.09 ppm), phosphate (117.21 ppm), COD (13640 ppm) and low DO content of 5.79 ppm were observed in the effluents released during the month of February. The alkalinity content in the effluent was maximum of 1395 ppm in the month of May. The hardness and BOD values of the effluents were reported maximum of 490 and 557 ppm in the month of October. 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.

    Opis:
    The present study was performed for the period of one year from June 2012 to May 2013 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 majority of physco-chemical parameters like alkalinity, salinity and total solid content (TS) were observed to be maximum in the month of February having values of 3578, 44.08 and 40450 ppm respectively. The high cyanide (0.18 ppm) and phosphate (112.90 ppm) levels were reported in the effluents released during the month of March. The industrial effluent released in the month of June was reported to have high hardness, chloride and COD content having the values of 743, 2381, 8957 ppm respectively; while the DO content was found to be very low of 2.77 ppm. The BOD content in the effluents was found to be maximum of 603 ppm in the month of October. 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.

    The paper deals with monitoring of pollution arising due to fine chemicals manufacturing industries located along the Dombivali industrial belt of Mumbai, India. The study was carried for the period of one year from June, 2012 to May, 2013 to study the level of toxic heavy metals and the physico-chemical properties of waste water effluents discharged from the above industries. The concentration levels of heavy metals like Cu, Ni, Cr, Pb, Fe and Zn was found to be maximum of 45.94, 1.05, 7.50, 4.76, 145.87 and 21.96 ppm respectively in the effluents released during the months of February to April. The majority of physco-chemical parameters like alkalinity, salinity and chloride content were found to be maximum in the month of October having the concentration values of 1482, 4.91, 2710 ppm respectively, while the DO content in the effluents released in the same month was reported to be very much low having the value of 2.90 ppm. The effluents released during the month of June were reported to have high hardness, total solid (TS) content and COD values of 3713, 13638 and 6951 ppm respectively. The cyanide content (0.08 ppm), phosphate content (131.32 ppm) and BOD content (631 ppm) were found to be maximum in the months of December, February and May respectively. From the results it appears that as India moves towards stricter regulation of industrial effluents to control water pollution, greater efforts are required to reduce the risk to public health as toxic pollutants which are mainly colourless and odourless can be expected to be released into the ecosystems.
