Levels of polycyclic aromatic hydrocarbons (PAHs) in the Densu River Basin of Ghana

Abstract: The concentrations of 16 polycyclic aromatic hydrocarbons (PAHs) in Densu River Basin in Ghana were measured using gas chromatograph. Surface water samples were collected from nine stations, namely, Potroase, Koforidua Intake, Suhyien, Mangoase, Asuboi, Nsawam Bridge, Afuaman, Ashalaga, and Weija Intake in the Densu Basin. Total PAH concentrations varied from 13.0 to 80.0 μg/mL in the Densu River, with a mean value of 37.1 μg/mL. The two- to three-ring PAHs (low-molecular-weight PAHs) were found to be dominant… Show more

“…Polycyclic Aromatic Hydrocarbons (PAHs) are ubiquitous compounds in the environment, detected in various compartments such as water (Latimer and Zheng, 2003;Amoako et al, 2011), sediments (Latimer and Zheng, 2003;Srogi, 2007;Van Drooge et al, 2011), soils (Jensen et al, 2007;García-Alonso et al, 2008;Desaules et al, 2008), organisms (Meador, 2003;Perugini et al, 2007;Srogi, 2007) or air (Ravindra et al, 2008;Van Drooge and Ballesta, 2009;Yan et al, 2009;Sheesley et al, 2011). Most of PAHs come from the incomplete combustion of organic materials and are potentially carcinogenic and mutagenic for human beings (Atkinson and Arey, 1994;Kang et al, 2011;IARC, 2011).…”

“…Increase in precipitation correlates with increase in river flow rate. Peak water velocities through the wetland should not exceed 0.457 m/s [4,5]. High velocities can wash out rooted vegetation and scour deposited sediments.…”

“…Ideally, flow velocities should be less than 0.183 m/s. A wetland with a high vegetation density will correspond to low flow rate and low turbidity values [5]. reported a 60 -90% reduction factor for turbidity in a constructed wetland at low flow rates [6].…”
