Determination of some polycyclic aromatic hydrocarbons (PAHs) associated with airborne particulate matter by high performance liquid chromatography (HPLC) method
In this study, polycyclic aromatic hydrocarbons (PAHs) associated with airborne particulate pollutants of aerodynamic size 10 μm (PM10) were studied for three months, from October to December 2010 in the Vanderbijlpark area. Some PAHs are highly carcinogenic and could be more harmful when combined with inhalable PM10. A dual E-Sampler which combines the light scatter and the gravimetric filter methods was used. A 10...

Benthic macroinvertebrate community of a fourth order stream in Kashmir Himalaya, India
The study was conducted in order to determine the abundance of benthic macroinvertebrates in Doodhganga stream passing through Brenwar forest (Yousmarg) Kashmir. Altogether 6 orders under 2 phyla namely: Arthropoda and Annelida were recorded from the stream. Inspite of the torrential flow of the stream, the hard substrata like boulders and cobbles provided a stable habitat for diverse number of macroinvertebrates. The...

Batch adsorption of heavy metals (Cu, Pb, Fe, Cr and Cd) from aqueous solutions using coconut husk
This study was carried out to evaluate the efficiency of metals (Cu, Fe, Pb, Cr and Cd) removal from mixed metal ions solution using coconut husk as adsorbent. The effects of varying contact time, initial metal ion concentration, adsorbent dose and pH on adsorption process of these metals were studied using synthetically prepared wastewater. The percentage removal of metals increased with increasing weight (0.4-1.2 g)...

Assessment of heavy metals concentration in soils around oil filling and service stations in the Tamale Metropolis, Ghana
This study was conducted to assess the level of heavy metals contamination of soil around oil filling and service stations in the Tamale Metropolis. Soil samples were collected from various oil filling and service stations. Elemental analysis of samples was conducted using atomic absorption spectrometer at Atomic Energy Laboratory, Accra. The metals concentrations ranged from 2.37 to 15.00 mg/kg for Cr; 0.01 to 0.03...

Determinants of domestic water consumption in a growing urban centre in Osun State, Nigeria
Household access to potable water is required for sanitation and general well-being. This challenge is under the influence of variables that play both temporal and spatial roles. This research examines the determinants of domestic water use in Iwo, Osun State, Nigeria. Ten households each were randomly selected from ten of the fifteen political wards in the town for the administration of 100 copies of questionnaire....
