Municipal solid waste management in India is becoming important in view of the fact thatincreasing amount of solid waste generated in most cities is now being recognized as a major publichealth problem. Poor management of solid waste leads to problems, which transcend traditionalenvironmental boundaries and contribute to air, waters and soil pollution,The percentage of India's population living in cities and urban areas has doubled to 28.8% by 200 Ifrom 14% at the time of Independence, showing the rapid pace of urbanization. The progressivelyimproved standards of living and the wasteful consumer attitudes have resulted in increase ofquantities of municipal wastes to be handled.The present system of solid waste management in India, like any other developing country, isfraught with many inadequacies. Illegal dumping is a major problem that raises significant concernswith regard to safety, property values, and quality of life in our communities. Poor collection ordisposal practices are the problem. Since most cities in India still lack properly engineered landfillsfor safe disposal, waste here is mostly disposed in open dumps, which causes major environmentalhavoc.Apart from other environmental hazards from open dumping of municipal solid waste, one of themajor problems that rise are the uncontrolled emissions of VOCs or Volatile organic Compounds.VOCs are well known to be hazardous to human health and are potent carcinogens,The present paper deals with qualitative and quantitative identification of VOCs from a twomunicipal waste dump site in Mumbai. Air at dump sites was sampled and analyzed on GC/MS inaccordance with USEPA TO-17 compendium method for analysis of toxic compounds. As many as20 VOCs were qualitatively identified and some VOC's were quantified, Concentration of Benzenewas observed in the order of 0.6ppm, Some of the VOCs identified were Hazardous Air Pollutantsaccording to USEPA clean air act amendment of 1990,

The present investigation discusses the characteristic of leachate generated from municipal solid waste landfill and it adverse impacts on downstream water quality. Landfill leachate was collected from a hole dug 10 m away from the waste dump site and the appearance of the leachate sample looks black. Three downstream water samples were collected at 10 meters intervals each from each other and less than 100 meters from the boundary of the dumpsite. All the samples were examined for temperature, pH, TDS, TSS, BOD, COD, nitrate, ammonia, Cu, Ni, Pb, Cd, Cl, total phosphate, sulfate, EC, DO and turbidity. The aim was to compare physicochemical and heavy metal properties of leachate and downstream water quality with internationally accepted protocols. The Laboratory analysis exhibited prevalence of high value of pH (8.5130.09), temperature(29.00.0), turbidity (14.00.41NTU), DO (0.1670.05 mg/l), COD (68.00.33 mg/l), BOD5 (324.03.00 mg/l), EC (446315.53s/cm), Total phosphate (62.3580.01 mg/l), Pb (0.310.00 mg/l), Cd (0.060.00 mg/l), Ni (0.3550.01 mg/l), and Cu (8.670.04 mg/l) in the leachate sample, which have exceeded their permissible limits. For downstream water samples, pH (7.760.07 to 7.5070.09), temperature (29.00.00) for the three sampling points, DO (3.6670.15 to 3.2330.12 mg/l), total phosphate (8.2250.00 to 7.9350.02 mg/l), Pb (0.4650.01 to 0.0910.00 mg/l), Cd (0.040.00 to 0.0230.00 mg/l), Ni and Cu (0.0430.06 mg/l) and (1.0620.00 mg/l) respectively, also exceeded their respective permissible limit recommended by Nigerian Standard for Drinking Water Quality, World Health Organization in drinking water quality. From this study, there is evidence that there is an increase in risk to surface water that is reported near Uyo village road municipal solid waste dumping site. Therefore, the concerned authority should take appropriate intervention measures to protect surface water. Also, knowledge of leachate quality will be useful in planning and providing remedial measures to protect downstream water quality in the area.

<strong>Aims:</strong> The purpose of this project is to find the concentration of heavy metals (Cu, Zn, Pb, As, Cr, Ni, Cd, Fe and Mn) in the top soil and the plant around the waste dumpsite from Enugu municipal solid waste disposal sites. <strong>Methodology and results: </strong>This was done through collection of soil samples from four designated public municipal solid waste dump sites (Ngwo Umueze, Presidential, New-market and Emene) in Enugu metropolis. The soil samples were collected at 10 metres intervals away from the centre location point of each dump site at constant depth (0 - 15 cm were mixed together and sample picked from it). The samples collection design are as follows: centre (0m) of the dump sites, 10 metres, 20 metres, 30 metres and the control sample which measured 65 metres away from the centre of dumpsites at the same depth. Plant samples were taken just at the centre (0m) and control measures which is at 65 meters distance away from each dump sites. The Goat grasses harvested were taken to the lab to check and analyse its heavy metals intake from the soil. These samples were analysed using atomic absorption spectrophotometer (AA320N) model. On the average, high concentrations of Zn, Fe, Mn, Cu, and Pb were found in the soil samples collected at the centre of the dump sites as 141.70, 121.5, 75.53, 70.33 and 64.53mg/kg respectively. The lower concentrations were obtained in the soil samples taken at the control site which 65 metres distance away from the centre of the four dump sites as 12.00, 81.55, 8.70, 9.56 and 6.51mg/kg for Zn, Fe, Mn, Cu, and Pb respectively. In the plant sample, concentration of Fe (98.00 mg/kg) was found to be the highest in the root at New market dumpsites, while Nil concentration of as (Nil mg/kg) was the least value at Emene from the control distance. <strong>Conclusion, significance and impact study:</strong> SPSS statistical package was used to find out the significant differences between the treatments mean (heavy metals). The result shows that the heavy metals analyses were within the acceptable or permissible limit by WHO/FAO.
