“…Orji et al [30] reported a pH of 7.41, very slightly alkaline lower than that in this present soil study. In other literatures, the authors [31][32][33] reported similar slightly alkaline pH values as found in this study while others reported acidic pH values [34][35][36]. Frankenberger and Arshad [37] and Sharma [32] explained that biodegradation of hydrocarbon in contaminated soil is enhanced when the pH of the soil is neutral or slightly alkaline.…”

The Biodegradation of spilled crude oil in contaminated soil could reach insignificant quantity and harmless compounds formed through the application of effective and viable hydrocarbon degraders. In this study, 15 micro-organisms were isolated, sub-cultured, purified and used for the bioaugmentation process of a crude oil contaminated soil. The isolated consortium used the crude oil as their sole carbon source and in the process lead to the bio-degradation of the oil contaminant. The quantity of residual oil obtained following bio-augmentation with each isolate was determined gravimetrically. The best hydrocarbon degraders identified include: Staphylococcus epidermis, Pseudomonas Spp, Baccilus Spp, Klebsiella Spp., Micrococcu Spp. These findings from this study have environmental implication as it could help in the selection and application of bacterial species that can be used for effective bio-degradation of crude oil in contaminated soil in the Niger Delta region of Nigeria through bio-augmentation process.

“…The levels of Hg in soils of Anka area were recorded in the range of 2153 -12924 µgkg -1 which is higher than the values in this research [31]. The levels of Hg in industrial soils in Kaduna State were recorded to be 28800 µgkg -1 which is higher than the values reported in this research [32]. The levels of Hg distribution in polluted soils in the range of 220 -1880 µgkg -1 were recorded which are higher than the values reported in this research [33].…”

Mercury levels in agricultural soils and three citrus varieties (Washington, Ibadan Sweet and Valencia) in seven (7) local government areas of Benue State were determined using standard techniques. The mean physico-chemical parameters of the soils ranges from: pH (5.20-6.10); CEC (10.5-12.9 cmolkg-1); organic carbon (2.35-3.39%) and organic matter (6.17-7.37%). The mean Hg levels in the soils ranges from 20.5-21.2 µgkg-1. The mean proximate parameters are: fat in Valencia (0.330%); fibre in Valencia (0.490%); moisture in Valencia (87.4%); ash in Valencia (1.80%) and carbohydrate in Ibadan sweet (17.7%). The mean Hg concentration in the citrus juice ranges from: Washington (0.770-6.35 µgkg-1); Ibadan sweet (0.770-6.53 µgkg-1) and in Valencia (0.770-5.22 µgkg-1). The order of accumulation of Hg in the citrus varieties is Ibadan sweet > Washington > Valencia. The concentrations of Hg in the three citrus fruit juice and soil do not exceed the WHO/FAO permissible limits of 100 and 1000 µgkg-1 for foods and agricultural soils respectively. However, continues monitoring is hereby recommended.

Background.Consumption of plants such as Carica papaya grown around automobile workshops is common in big cities in Nigeria. However, little is known about the heavy metals contamination of these consumables due to the influence of automobile emissions during maintenance activities.Objectives.This study aimed to assess heavy metal concentrations in C. papaya and supporting soils around automobile workshops in Port Harcourt Metropolis, Rivers State, Nigeria.Methods.Seven automobile workshops were used for the present study. First, 20 m × 20 m quadrats were laid out for soil and C. papaya tissue sampling. One composite soil sample was collected from the topsoil (0–15 cm depth) around each of the automobile workshops. Three C. papaya stands at least 30 cm apart around each workshop were used for the study and from these stands, tissues (root, stem, leaf, fruit) of C. papaya were collected. Standard laboratory techniques were used to determine the pH, electrical conductivity (EC) and heavy metals (lead (Pb), mercury (Hg), cadmium (Cd), copper (Cu), and zinc (Zn)) in the soil samples and C. papaya tissues. Pairwise t-test was used to determine significant differences (p<0.05) in the heavy metal concentrations in soil and C. papaya tissues between the sample and control sites, while correlation statistics were used to determine the relationship of heavy metal concentrations between soil and C. papaya tissues.Results.C. papaya tissues and supporting soil had significantly higher levels of pH, EC and heavy metals in the sampled plots than the control plot. The heavy metal concentrations in C. papaya and soil occurred in the decreasing order of Pb>Cu>Hg>Zn>Cd. The fruit of C. papaya had the highest mean concentrations of Pb (51.4±14.1 mg/kg) and Zn (26.4±1.9 mg/kg), while the leaf had the highest mean concentration of Hg (32.0±2.3 mg/kg). The pH, Cu and Zn in the supporting soil were significantly correlated with the levels in the C. papaya tissues.Conclusion.Bio-accumulation of heavy metals by C. papaya is evident around automobile workshops, and Pb, Hg, Cd concentrations were found to be above the permissible limits for human consumption according to World Health Organization (WHO) standards. Consumption of food materials grown around automobile workshops could pose health risks.
