Assessment of some heavy metals in the surrounding soils of an automobile battery factory in Ibadan, Nigeria

The levels of heavy metals (Pd, Zn, Cr, Cd, Fe and Cu in mg/kg) in soils were assessed with respect to distance in different directions around an abandoned battery company in Ibadan, Western Nigeria by using flame atomic absorption spectrophotometry method. The results generally show a decrease of lead (Pb) concentrations with increase in distance away from the company in all the four different directions (Northwest,...

Pollution assessment and heavy metal determination by AAS in waste water collected from Kushtia industrial zone in Bangladesh

This study was to investigate the contamination level of waste water in the Kushtia industrial region of Bangladesh. Some parameters of waste water were analyzed like pH, electrical conductance, total dissolved solids (TDS), hardness, biochemical oxygen demand (BOD5), chemical oxygen demand (COD), and for heavy metal (Pb, Cd, Cr, Cu, Mn) concentration. The pH was found to be of range from 8.485 to 4.187; whereas, the...

Projections of precipitation, air temperature and potential evapotranspiration in Rwanda under changing climate conditions

Precipitation and air temperature records from 6 sites in Rwanda in the period from 1964 to 2010 are used for past/present climate assessment. Future climate projections (2010-2099) based on 3 general circulation models and 2 emission scenarios (A2 and B1) are used for climate projections. Precipitation, air temperature, and potential evapotranspiration based on ccma_cgcm3_1.1; miroc3_2medres and mpi_echam5.1 models are...

Seasonal impact on phyto-accumulation potentials of selected edible vegetables grown in Ishiagu quarry mining effluent discharge soils

Seasonal impact on soil trace metals and phytoaccumulation potentials of Cucurbita pepo, Cucumis sativus and Taliferia occidentalis grown in Ishiagu quarry mining effluent discharge soils were investigated. Soil samples were collected 200 m (sample C), 100 m (sample B) away from discharge point (sample A) in wet and dry seasons. Trace metals were analysed using atomic absorption spectrophotometer. Results reveal a...

Evaluation of the impact of mine activity on surrounding soils of Draa Lasfar mine in Marrakech- Morocco

Heavy metal pollution is one of the most important problems in Morocco and causes serious effects to humans and animals. The aim of the present study was to evaluate the spatial distribution of heavy metals in Draa Lasfar mine area in Marrakech city and understand the characteristics of the pollution generated by this mine activity. A total of 120 soil samples were collected from Ouled Bou Aicha and Tazakourte along...
