Construction features and benefits include equal inlet and outlet pressure rating, optional noise abatement, straight-through flow design, in-line maintenance, optional aromatic hydrocarbon
construction, high capacity, modular design, tight shut-ff, and zero-bleed gas.
pi-electron densities are uniformly or symmetrically distributed over the molecule.
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.
There are very few studies that consider monitoring the effects of a polycyclic aromatic hydrocarbon
spill; most have been done with biomarkers, without any analytical quantification .
For any positive integer n, let [PAH.sub.n] be the general representation of this Polycyclic Aromatic Hydrocarbon
shown in Figure 1.
Different volumes (4, 12, and 20 mL) of a tea infusion spiked with 5 ng of each polycyclic aromatic hydrocarbon
were treated with the same volume of extracting solvent (4 mL) for 20 min.

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.
