Pesticide exposures in a malarious and predominantly farming area in Central Ghana
In areas where malaria is endemic, pesticides are widely deployed for vector control, which has contributed to reductions in malaria deaths. Pesticide use for agrarian purposes reduces pest populations, thus improving crop production and post-harvest losses. However, adverse health effects have been associated with pesticide exposure, ranging from skin irritation to neurotoxicity and carcinogenicity. Though misuse of...

Biosorption of nickel (II) ions from aqueous solutions by tapioca peel
Tapioca peel, waste from native tapioca starch industry in Thailand, was used for the biosorption of nickel from aqueous solution. The experimental parameter focuses on the influence of contact time, solution pH, initial concentration and temperature using batch experiments. The results indicated that the biosorption process was relatively fast, and equilibrium was reached after about 30 min of contact. At pH 5, the...

Environmental impact assessment of waste electronic and electric equipment (WEEE) management practices in developing countries through leaching tests
Increasing quantities of domestic and imported waste electronic and electric equipment (WEEE) stimulates a rapid development of informal recycling activities in developing countries. This economically driven recycling, oftentimes based on open burning or acid-base treatment, followed by open dumping of the residues, does not usually fit environmental and public health requirements. For the underlying research, the...

Monitoring of metals in Tilapia nilotica tissues, bottom sediments and water from Nworie River and Oguta Lake in Imo State, Nigeria
Tilapia (Tilapia nilotica), bottom sediments and water were collected from Nworie River and Oguta Lake. The muscle, liver and gills of the fish as well as the bottom sediments and water were analysed for Al, Cr, Cd, Pb, As, Zn, Mn, Co, Se, Cu, Ni and Fe using atomic absorption spectrophotometer to highlight the importance of tissue selection in monitoring research, contamination studies and human health risk assessment....

Spatio-temporal Variations of Abundance, Biomass, and Reproductive Parameters of Pseudodiaptomus hessei (Mrazek, 1895) (Copepoda Calanoida) in a West African Coastal Lagoon (Grand-Lahou, Côte d’Ivoire)
The spatio-seasonal variations of Pseudodiaptomus hessei abundance, biomass and reproductive parameters were investigated in the Grand-Lahou lagoon at five stations during the dry and wet (or rainy) seasons from September 2005 to August 2006. In all sampling stations, abundance and biomass of P. hessei in the dry season were higher (0.16 to 2.17 ind.L-1, 0.45 to 4.97 µgC.L-1) than in the wet season (< 1...

Green roofs: A possible best management practice for enhancing the environmental quality of Ghanaian cities
City expansion typically erodes the natural ability of the locale to perform its ecosystem services. This paper discusses green roofs and their potential benefits for Ghanaian cities in terms of improving environmental quality. Limited analysis shows that daily minimum temperatures of cities like Accra are rising faster than the daily maximum thereby decreasing the comfort index of city dwellers. Electricity consumption...
