<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.

Abstract Background An increase in the urban population and the rising demand for food and other essentials perpetuate a rise in the amount of waste being generated daily by each household. In low-income countries, this waste is eventually thrown into open dump sites. It can cause severe impacts on human health and the surrounding environment. This study was aimed at assessing the effect of a solid waste dump site of Teppi town on surrounding soil and river water quality. Methods A total of three surface water, one leachate water samples, and four soil samples were collected and were analyzed. Six heavy metals for surface water and leachate samples and four heavy metals for soil samples were measured by flame atomic absorption spectroscopy. Additionally, physical and chemical parameters were analyzed using standard methods. The soil and water data were analyzed statistically using Origin pro version 8.0 computer software packages. Analysis of variance (ANOVA) was used to assess whether the mean values of heavy metals and physicochemical parameters in soil and water samples varied significantly between distances and location from the dump site, possibilities less than 0.05 (p< 0.05) was considered statistically significant. Results pH of soil was slightly basic (pH 8±0.1 up to 8.7±0.21. Similarly, EC was lower in 60 meters (1800±0.5μs/cm) and higher in the other sample sites (3490±0.66-4920±1.04μs/cm). The concentration of heavy metals such as cadmium (0.53±0.01-2.26±0.02 mg/kg), zinc (623.93±0.29-859.41±0.02mg/kg), lead (3.26±0.25-57.560.26mg/kg), and copper (204.06±0.06 337.11±0.01mg/kg) in the sample soils has been found to be higher than Ethiopian EPA and USEPA guideline values. Lead, cadmium, manganese, nickel, copper, and zinc in the leachate water and nickel and manganese in nearby river water, total dissolved solid, BOD5, chemical oxygen demand, and turbidity for both leachate and stream water samples were found to be higher than the Ethiopian EPA and WHO standard guideline values. Conclusions The finding suggested that solid waste open dump site adversely affects soil and water quality in the study area and probable source of human health risks via the food chain. The soil in the area requires Phytoremediation technologies. In addition, sanitary landfill is recommended.

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,

An increase in urban population and the rising demand for food and other essentials perpetuate a rise in the amount of waste being generated daily by each household. In Ethiopia, this waste is eventually thrown into open dump sites. It can cause severe impact on soil and surface water quality. As a result, it becomes the probable source of human health risk through food chain. Therefore, this study was aimed at assessing the effect of a solid waste dump site on surrounding soil and river water quality in Tepi town, Southwest Ethiopia. Three surface water, one leachate, and four soil samples were collected and analyzed. Six heavy metals for surface water and leachate samples and four heavy metals for soil samples were measured by flame atomic absorption spectroscopy. In addition, physiochemical parameters were analyzed using standard methods. The data were analyzed statistically using Origin pro version 8.0 computer software packages. The pH of soil was slightly basic ranging from 8 ± 0.1 to 8.7 ± 0.21. Electrical conductivity was lower at 60 meters (1800 ± 0.5 μs/cm) and higher in the other sample sites (3490 ± 0.66–4920 ± 1.04 μs/cm). The concentration of heavy metals in soil samples revealed cadmium (0.53 ± 0.01–2.26 ± 0.02 mg/kg), zinc (623.93 ± 0.29–859.41 ± 0.02 mg/kg), lead (3.26 ± 0.25–57.560.26 mg/kg), and copper (204.06 ± 0.06–337.11 ± 0.01 mg/kg). Lead, cadmium, manganese, nickel, copper, and zinc were found in the leachate water; nickel and manganese were found in the nearby river water; BOD5 and COD for both leachate and stream water samples were found to be higher than standard guideline values. The finding suggested that solid waste open dump site adversely affects soil and water quality in the study area and becomes a probable source of risk for human health via the food chain.

Adverse Impacts

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.
