The study examined municipal solid wastes characteristics of Gosa dumpsite at Abuja, Nigeria. Waste characterization has not yet been given adequate attention in management of waste in Nigeria and it is a major problem that affects waste materials handling and recovery processes. Wastes samples from Gosa waste dump site, Abuja, were randomly collected and subjected to moisture content, composition, density and size distribution determinations according to prescribed standards in literature. The moisture content of the Gosa waste solid was 19.3%.  The results of the characterization of the Gosa municipal solid wastes show 34% organic, 10% paper, 28% plastic, 2% glass, 6% metal, 4% fabric, 2% rubber and 14% dust. The average density of glass, metal, plastic, fabric, rubber, paper, organic and dust materials were 0.044 kg/m3, 0.045 kg/m3, 0.176 kg/m3, 0.043 kg/m3, 0.042 kg/m3, 0.074 kg/m3, 0.143 kg/m3 and 0.098 kg/m3, respectively. The size distribution of the Gosa solid waste ranges from 10-28 cm for metals and plastics and 3-13 cm for paper and glass. The rubber had size ranges from 8-23 cm while size ranges of organic was from 3-6 cm. The large presence of organic, plastic, paper and metal wastes at Gosa waste dump site, is an indication that the municipal solid wastes can be sorted, recycled and processed to other useful products, using the characteristics as a guide.Keyword:  Characterization, Density, Municipal Solid Waste, Size Distribution, Waste Management

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,
