Leaching behaviour of azoxystrobin in sandy loam soil
The mobility of azoxystrobin in sandy loam soil was studied under continuous and discontinuous flow conditions in soil columns under laboratory conditions at two application rates (50 and 100 μg), with simulated rainfall of 300 mm. Residues of azoxystrobin in soil and leachate were estimated by gas-liquid chromatography and confirmed by gas chromatography-mass spectrometry. Though maximum concentration of...

Characterization of Dabagi clay deposit for its ceramics potential
A clay deposit in Gwandu Town of Kebbi State, Nigeria has been evaluated for its potential as industrial raw material. The chemical analysis was carried out using X-ray florescence spectrometery while physical property tests such as porosity, bulk density, linear shrinkage, thermal shock resistance, cold crushing strength and refractoriness were done using standard techniques. The result of chemical analysis indicated...

Heavy metals accumulation in edible part of vegetables irrigated with untreated municipal wastewater in tropical savannah zone, Nigeria
In this present study, the quality of municipal wastewater used for irrigation of spinach was investigated for its heavy metal build-up. The municipal wastewater used for irrigation and the irrigated spinach samples were collected and analyzed for their heavy metal concentrations. The results indicate that the municipal wastewater used was contaminated with copper (1.90 mg/l), lead (0.09 mg/l) and iron (25 mg/l) and the...

Spatial distribution, chemistry and subsurface temperatures of geothermal springs in Nkhata bay, Malawi
This study investigated the spatial distribution, chemistry and subsurface temperatures of geothermal springs in Nkhata Bay, Malawi, which lies in the Western Branch of the East African Rift System. Seventeen geothermal springs were identified and mapped in the District. Eleven of these geothermal springs were purposively sampled for chemistry study on the basis of their spatial distribution representativeness and...

The absorption and scavenging ability of a bacillus in heavy metal contaminated soils (Pb, Zn and Cr)
A bacterial strain, which was able survive Pb, Zn and Cr -heavy metal compound culture was isolated from the soils of Shanjia Villiage, Qufu City, Shandong Province. An observation of the morphological and biochemical characteristics of the compound and the analysis of 16SrDNA sequence revealed that it was Bacillus. Standing liquid culture was used to study the tolerance of Pb Zn Cr -heavy metals compound and the...
