“…4) could come from the high vehicular traffic and the high human population who may use firewood or charcoal for domestic heating. The high concentrations of total PAHs in the surface soils from these severely polluted communities could pose high environmental and human health risks (Ping et al, 2007). The study indicated that in these communities (Adum, Romanhill, Mbrom, Suame and Suntreso), PAHs compounds including the human carcinogenic compounds (BaA, BbF, BkF, BaP, DBahA, Chr and IcdP) (IARC, 2006) were high (Table. 2).…”

As a developing country, the economic and population growth rates in Ghana over the past few years have seen tremendous increase. The growing rate of industrialization is gradually leading to contamination and deterioration of the environment and pollution is likely to reach disturbing levels. Surface soil samples were collected randomly from 36 communities in the Kumasi metropolis, Ghana, to determine the concentrations, distribution, sources and toxic potential of emission of polycyclic aromatic hydrocarbons (PAHs) since no such comprehensive study has been conducted. The mean concentration of total PAHs in the surface soils in each community ranged from 14.78 at Ahinsan to 2084 ng/g dry weight at Adum with an average of 442.5 ± 527.2 ng/g dry weight. Diagnostic ratios and chemical mass balance models of the results showed that PAHs in surface soil samples from the study area were mainly from fuel combustion.Carcinogenic potency of PAHs load from the city centre was approximately 150 times higher as compared to a pristine site, Kwame Nkrumah University of Science and Technology's Botanical Garden. BaP, a human carcinogen, contributed 70% of the total PAHs toxicity level from the city centre of Kumasi.

“…The second 2-ml aliquot of elute was collected, dried by sparging with N 2 , and dissolved in 1 ml hexane (Ping et al 2007). Sixteen US Environmental Protection Agency (USEPA) priority PAH compounds were identified and quantified using GC-MS. An Agilent 7890N GC system and Agilent 5795B series MSD equipped with G6500-CTC autosampler was used.…”

Background and aims The objectives of this study were to examine the effect of direct inoculation of seeds with the rhizobacteria Pseudomonas sp. SB on the growth of tall fescue and phytodegradation efficiency in an oily-sludge-contaminated soil. Methods SB isolated from rhizosphere soil of tall fescue was evaluated for their plant-growth-promoting characters and ability to produce biosurfactant. A pot experiment was conducted to study the effect of inoculation of SB on phytoremediation.Results SB reduced the surface tension of culture media and produced indole acetic acid, siderophores, and 1-aminocyclopropane-1-carboxylate deaminase. Inoculation of SB increased shoot and root dry weights of tall fescue in oily-sludge-contaminated soil by 28 % and 19 %, respectively. Over 120 days, the content of total petroleum hydrocarbon in soil decreased by 33.9 %, 68.0 %, and 84.5 %, and of polycyclic aromatic hydrocarbons (PAHs) by 32.9 %, 40.9 %, and 46.2 %, respectively, in the no-plant control, tall fescue, and tall fescue + SB treatments. Inoculation of SB also increased the activity and biodiversity of soil microbial communities in the planted treatments. Conclusions SB could produce biosurfactant and exhibited a number of characters of plant-growthpromoting rhizobacteria. Inoculation of SB to tall fescue led to more effective remediation of oilysludge-contaminated soils.
