Abstract: Auto mechanic activity in the recent time has significantly contributed to environmental degradation partly due to poor waste management practices and weak enforcement in ensuring operators are located in designated sites. This study therefore investigated the distribution pattern of Poly Aromatic Hydrocarbon (PAH) contaminants around Nekede auto-mechanic village, Owerri. Soil samples (0-30cm) were collected at three separate points. Sediment samples were also collected from two points along the Otamiri River representing sediments (RS) 1 and 2 and a control sample where no mechanic activity existed. Physicochemical parameters were determined using standard methods and Gas Chromatographic system equipped with a single detector (Flame Ionization Detector) — GC-FID for PAHs. The results obtained showed that out of the sixteen US-EPA target PAHs (EPA-16) analysed, only eight were detected in varying concentrations. Total PAH concentrations in the samples were in the order of dibenz {ah} anthracene (29.111mg/kg) > indeno {1, 2, 3-cd} pyrene (20.178mg/kg) > anthracene (10.717mg/kg) > naphthalene (8.340mg/kg) > 1, 2-benzoanthracene (4.124mg/kg) > acenaphthene (2.784mg/kg) > benzo {ghi} perylene (2.324mg/kg) > fluorene (1.421mg/kg). The concentration of total PAH components detected in the samples ranged from 2.564mg/kg to 21.841mg/kg in the study site compared to that of the control site where no PAH component was detected. The results therefore call for public concerns as PAH levels exceeded the maximum permissible limits set by some regulatory bodies. Public health education and regulation on management of wastes in the auto-mechanic workshops are recommended for environmental sustainability.

Abstract: The present study was carried out to investigate the interrelationships between some physical and chemical soil characteristics and alfalfa productivity at El-Sadat area, Monufyia Governorate during 2013/2015 years. Eight surface soil samples (0-30 cm) from each location were correlated for the investigated soil indicators determination. The investigated indicators were the coarse sand (CS), fine sand, silt and clay content, bulk density (BD), real density (RD), total porosity (TP), quickly drainable pores (QDP), slowly drainable pores (SDP), water holding capacity (WHC), hydraulic conductivity (HC), field capacity (F. C), wilting coefficient (WC), mean weight diameter (MWD); pH, electric conductivity (EC), organic matter (OM), cation exchange capacity (CEC), calcium carbonate (CaCO3), available potassium (Av-K) and total nitrogen (TN). The highest values of mean standard deviation and the relative weight of physical and chemical indicators were obtained for organic matter represents the important relative weight followed by cation exchange capacity, total nitrogen, clay content, total porosity, field capacity and quickly drainable pores. Concerning the relationship of some soil parameters and alfalfa productivity, the data of correlation studies showed that the most suitable indicators for evaluation of soil quality under different soil management of study area were organic matter, cation exchange capacity, total nitrogen, clay content, total porosity, field capacity and quickly drainable pores.
