The paper deals with monitoring of pollution arising due to pharmaceutical based 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 level of majority of toxic heavy metals like Cu, Cr, Pb, Fe and Zn were found to be maximum of 14.06, 0.57, 0.42, 18.93 and 3.31 ppm respectively in the month of February, while Ni concentration was found to be maximum of 0.43 ppm in the month of June. The pH and BOD values were reported to be maximum of 12.54 and 546 ppm respectively in the month of October. The conductivity and total solid content was found to be maximum of 27400 μmhos/cm and 9401 ppm respectively in the month of June. The cyanide content was maximum of 0.13 ppm in the month of April. The alkalinity, hardness, salinity, chloride, phosphate and COD content was reported maximum of 852, 694, 10.36, 4821, 46.32 and 1271 ppm respectively in the month of February. The DO content was found to be minimum of 3.00 ppm in the month of February. It was observed that the level of many of these toxic heavy metals except Zn and various physico-chemical parameters were above the tolerable limit set for inland surface water. 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 Indians are dependent.

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.

The paper deals with monitoring of pollution arising due to agrochemicals and pesticides 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 average concentration of Cu, Ni, Cr, Pb and Zn was found to be maximum of 29.86, 0.90, 1.16 and 1.19 ppm respectively in summer season, while average Fe concentration was maximum of 51.10 ppm in winter season. The average pH value of the effluent was found to be maximum of 12.95 in summer season, while average conductivity value was maximum of 21085 μmhos/cm in rainy season. The majority of physco-chemical parameters like alkalinity, hardness, salinity, chloride, cyanide, phosphate, total solid, BOD and COD content were found to be maximum in summer season having the average values of 1918, 186, 4, 11.20, 0.07, 81, 6391, 685 and 2556 ppm respectively. The average DO content was found to be low of 4.5 ppm in winter season. It was observed that the concentration level of majority of the toxic heavy metals and physico-chemical properties were above the tolerable limit set for inland surface water. 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 textile based 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 level of majority of toxic heavy metals like Cu, Ni, Pb, and Zn were reported to be maximum of 45.58, 2.00, 2.06 and 9.20 ppm respectively in the month of April, while Cr and Fe concentration levels were found to be 2.50 and 55.30 ppm in the month of March. The effluent samples collected in the month of July was reported to show high BOD content of 564 ppm, while COD content was maximum of 2436 ppm in the month of October. The effluent samples collected in the month of January was having very low DO content of 3.21 ppm and high cyanide content of 0.09 ppm. The alkalinity, hardness and chloride content were maximum of 2158, 198 and 2765 ppm respectively in the effluent samples collected in the month of February. The effluents were having high total solid content of 8269 ppm during the month of April, while the salinity and phosphate contents were reported high of 5.64 and 125.70 ppm during the month of May. It was observed that the concentration level of majority of toxic heavy metals and the values of various physico-chemical parameters were above the tolerable limit set for inland surface water. The present experimental data on environmental risk assessment studies due to textile industries may be regarded as an aid towards a better understanding of the problem arising due to such industries. There is a need to convey the message that prevention of adverse health effects and promotion of health are profitable investments for employers and employees as a support to a sustainable development of economics.

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.
