Assessment of the physicochemical parameters and heavy metals toxicity of leachates from municipal solid waste open dumpsite

Abstract: Heavy metals and physicochemical characteristics of the different sites of the municipal solid waste dumpsite at Olusosun Landfill, Lagos, Nigeria, were investigated. The dormant site of the landfill has the potential of being a source of immediate environmental risk compared to the active and abandoned site, with the active site exhibiting tendency to be a likely source of Pb, Cd and Zn pollution. Zn was the most abundant metal in the area (0.264–0.947 mg/L) while Cd concentration was the lowest (0.001–0.022 mg/L). Pb, Cd, Zn were from anthropogenic sources and correlated significantly with chemical oxygen demand and oil and grease. Cu and Cr were more abundant in the dormant site and are attached to the solids as indicated by their significant correlation with TS and SS. The physicochemical characteristic of the leachate from the landfill indicate that they were more alkaline in nature, with TA range of 2354 to 7946 mg/L while the chemical oxygen demand values was also high 518.14 to 725.01 mg/L. The comparative analysis of the dormant site with other dormant site reveal a moderate concentration of the parameters measured but could contaminate the neighboring groundwater if not checked.

Energy consumption and nigerian economic growth: an empirical analysis

Abstract: The study evaluates thecausal nexus between energy consumption andNigeria's economic growth for the period of 1975 to 2010. Secondary time-series data were analyzed using co-integration and ordinary least square techniques. Co-integration results show a long run relationship among the variables. The result shows that in the long run, total energy consumption had a similar movement with economic growth except for coal consumption. The empirical results reveal that petroleum, electricity and the aggregate energy consumptionhave significant and positive relationship with economic growth in Nigeria. However, gas consumption although positive, does not significantlyaffecteconomic growth. The impact of coal was negative but significant; therefore this is just the time to increase the use this resource to the nation's benefit. Therefore, the study recommends that government should encourage a level- playing field for all energy forms available in the country by diversifying its power-generation portfolio. Also, the government should continue to collaborate with the private sector within the context of public-private- partnership (PPP) to further exploit the opportunities in the sector in order to increase economic growth.
