Performance and risk assessment of bambara beans grown on petroleum contaminated soil and the biostimulation implications
The potential of Vigna subterranean commonly called Bambara beans for phytoextraction of copper in a crude oil contaminated soil was investigated. The contamination levels of crude oil in the soil for this pot experiment were 2, 4, 6, 8 and 10% (w/v). Amendments were added to increase the uptake and translocation of metal to aerial biomass. A range of amendments was tested for copper uptake enhancement...

Climate change and agricultural water demand: Impacts and adaptations
Global climate change related to natural and anthropogenic processes has been the topic of concern and interest world - wide. One of the most significant impacts of the ‘greenhouse effect’ is anticipated to be on water resources. Thus, the impact of climate change appears to be an additional component on top of the large number of existing water-related problems. The objective of the present paper...

Effect of automobile workshop on the health status of automechanics in N. W. F. P., Pakistan
Automobile workers are at high risk for lung, urinary tract, brain and skin cancers due to their direct exposure to polycyclic aromatic hydrocarbons (PAH) and lead (Pb) toxicity. The current study was aimed to assess the effect of automobile workshop environment on health of auto mechanics in N. W. F. P. Pakistan. A questionnaire was designed and blood samples were collected from the auto...

Heavy metal contamination of groundwater resources in a Nigerian urban settlement
The aim of the study was to create awareness on the effect of dumpsite on groundwater in developing countries, especially Nigeria. In order to achieve this, water samples were obtained from 20 randomly selected hand dug wells and boreholes in the area, in February and August, 2006. 10 leachates samples were also obtained from the dumpsite. From these samples, pH and conductivity were determined using a pH/conductivity...

Impact of soil amendment on phytotoxicity of a 5-month old waste engine oil polluted soil
The present study investigated the effects of soil amendment on the remediation of waste engine oil (WEO) polluted soil, as well as the eventual phytotoxic effects of remediated amended soil on some growth parameters of cowpea. There were over 50% reductions from the original concentrations of Fe, Mn, Zn, Cu, Cr, Cd, Pb, Ni and V in soil nine months after amendment. Significant reductions in polyaromatic...

Environmental isotopes investigation in groundwater of Challaghatta valley, Bangalore: A case study
Radiogenic isotopes (3H and 14C) and stable isotope (18O) together with TDS, EC and salinity of water were used to discriminate qualitative and quantitative groundwater age, probable recharge time, flow respectively in groundwater of Challaghatta valley, Bangalore. The variations between TDS and EC values of sewage, corporation water, bore and open wells with concomitant variations in salinity confirmed an...

Integrated study for automobile wastes management and environmentally friendly mechanic villages in the Imo River basin, Nigeria
Despite the overwhelming advantages of mechanic villages, their heavy metal pollution of soil due to poor waste management is causing serious ecological and public health concerns. Analytical results show that heavy metal concentrations (mgkg-1) above background levels in the upper 100 cm soil profiles of the Okigwe, the Orji and the Nekede mechanic villages in the Imo River basin, collectively range from 748...
