Seasonal variations in heavy metal concentrations in soil and some selected crops at a landfill in Nigeria
In this study, the seasonal variations in concentrations of the heavy metals - As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn - in soil and crops from a farm near the refuse dump site of Obafemi Awolowo University, Ile-Ife, Nigeria were investigated during the two major seasons of Nigeria. This was done to assess the pollution status of the farm and hence the safety levels of the crops produced. Soil and crop...
Local institutions for sustaining wetland resources and community livelihoods in the Lake Victoria basin
What should policy makers do in deciding between institutions promoting community livelihoods or sustaining wetland resources within an impoverished community? Prioritizing community livelihoods without understanding the impact of local institutions on wetland resources may only aggravate impoverishment. However, prioritizing sustainable wetland resource use may lead to short-term impoverishment with...
Changes in soil properties and plant uptake of heavy metals on selected municipal solid waste dump sites in Ile-Ife, Nigeria
In a study to evaluate the contributions of open municipal waste dump to soil heavy metals contamination and the modification of other soil physical and chemical parameters, soil samples were collected at various depths from the vicinity of major dump sites in Ile-Ife (latitudes 7°27Î„and 7°32Î„, longitudes 4° 22' and 4° 29'), Nigeria. The samples when analyzed, showed...
Urban effluent pollution from the Mghogha flow of the west, margin of the Mediterranean sea, Morocco
Tangiers bay, located in the extreme west of the Mediterranean Sea, and in the north west of Morocco, receives various pollutants through the Mghogha canal from urban and industrial rejections of Tangiers city. This survey was focused on physicochemical and geochemical characterization of the more exposed sites situated on Mghogha canal and on the bay coastline. Physicochemical analysis (Temperature (21 -...
Pathogenic diversity of Sclerotium rolfsii isolates, a potential biocontrol agent against Parthenium hysterophorus L.
Parthenium hysterophorus L. is a wide-spread weed creating problems for agriculture and public health. Microbes and their by products is now proved to be a worthy alternative to toxic chemicals used for weed management. We determined the relative pathogenicity of ten Sclerotium rolfsii isolates recovered from diseased parts of Parthenium collected during a survey of various habitats...
