According to the researchers Chisom Obasi, Nkechi Okoye, Uche Ekpunobi and Rosemary Arinze of the Department of Pure and Industrial Chemistry, Faculty of Physical Sciences in the research titled 'Distribution and Risk Assessment of Polycyclic Aromatic Hydrocarbon
Contamination Arising from Uncontrolled Electronic Waste Recycling in Aba, Nigeria,' the objective of the research was to study the level of polycyclic aromatic hydrocarbons
in soils and the potential human health and ecological risk assessed.

Elution with n-hexane gave the total aliphatic (TAH) fraction (F1) while hexane-dichloromethane (10:90 v/v) yielded the branched aromatic hydrocarbons
(F2) and elution with hexane-dichloromethane (50:50 v/v) yielded the aromatic hydrocarbon
fraction (ArH) (F3) .

On the basis of CFU/mL, the results of aromatic hydrocarbon
degradation by selected strains that were isolated from petrol contaminated soil are summarized in Table 3 and the percentage of bacterial strains that degraded aromatic hydrocarbons
(naphthalene, phenanthrene, biphenyl, anthracene and xylene) in Figure 4.

In Biluo Co oil shale samples, 38 aromatic hydrocarbon
compositions were detected, dominated by the following seven series: naphthalene (N), methylnaphthalene (MN), dimethynaphthalene (DMN), trimethynaphthalene (TMN), tetramethynaphthalene (TeMN), pentamethylnaphthalene (PMN) and ethylnaphthalene (EN).
