“…Polycyclic Aromatic Hydrocarbons (PAHs) are organic compounds that are among the ubiquitous environmental pollutants. PAHs primarily occur during the incomplete combustion of organic materials such as oil and coal and also naturally originate from coal deposits and volcanic activities [1,2]. These substances are a class of arenes which also possess substantial energies because they are made up of fused benzene rings [3].…”

This is the first study related to PAHs distribution in the Woji Creek (Nigeria), that points out potential contaminant sources. The study involved sampling of water and sediment from five stations along the creek monthly (from August to October in 2018). Samples collected were analysed for the concentration of sixteen Polycyclic Aromatic Hydrocarbons (PAHs) using an Agilent 7890B Gas Chromatograph (GC-MS). Eleven (11) PAHs were identified in the water samples with five (5) below detectable limits (Naphthalene, Phenanthrene, Pyrene, Indeno (1, 2, 3, -cd) pyrene and Benzo [(g), (h), (i)] perylene). Results from the surface water showed that in the month of September, the concentration ranged from 6.029 ppm in S4 to 28.331 ppm in S5. October recorded a PAHs concentration ranging between 6.094 ppm at S1 and 29.257 ppm at S5. In the sediment highest concentration of PAHs was recorded in S5; 1809.08 ppm in August, 1810.05 ppm in September and 1821.5 ppm in October. The concentrations of PAHs in sediment were significantly greater than those in the water. In both sediment and water samples, the highest concentrations of total PAHs were recorded in station 5 and the lowest in station 4. The composition of PAH in water identified the dominance of 2 and 3 rings (Low Molecular Weight (LMW) PAHs) over 4, 5 and 6 rings (High Molecular Weight (HMW) PAHs). In the sediment samples analysed, LMW PAHs (2-3 rings) made up about 30% of the composition, while HMW PAHs (4-6 rings) made up about 70% of PAHs member groups. Cross plots showed that the PAHs could have come from petroleum and combustion.

“…antibodies, enzymes and DNA). 10 As a strategy to achieve highly sensitive and selective biosensors, researchers have worked on combining different transducer/probe pairs to detect PAHs in the environment. Table 2 summarizes the achievements of some literature on biosensors developed for the detection of important PAHs by means of various combinations of probes and transduction mechanisms.…”

“…On the other hand, Damborský et al 32 highlight in the optical biosensors their small sizes leading to the possibility of fabricating portable devices that enables real-time measurements. In contrast to the abovementioned advantages of the biosensors, Behera et al 10 also pointed out some controversial shortcomings referring to the use of immunoassays as analytical methods. According to them, some immunoassays are less sensitive than traditional gas chromatography coupled with mass spectrometry, for example, and can lead to some misinterpretation.…”

“…9 In this regard, Hahm et al 9 enlist two important negative aspects of the chromatography: the longtime required for sample preparation and the incompatibility of the hydrocarbons with the chromatographic column. Behera et al 10 confirm the difficulty in preparing the samples as a major issue in using aforementioned techniques for detecting PAHs, mainly because of the volatility and lipophilic nature of these compounds that can alter their integrity from the collection to the analysis. Moreover, the researchers cite the unitary cost of each assay and the high expertise required to perform the detection as other disadvantages of the conventional methods.…”

“…Moreover, the researchers cite the unitary cost of each assay and the high expertise required to perform the detection as other disadvantages of the conventional methods. For a simple, quick, cost-effective and in situ detection of PAHs in their various possibilities of environments, Behera et al 10 mention the biosensors as promising candidates to overcome the limitations of the current assays. Biosensors belong to a category of analytical devices that are capable to provide a measurable output signal by means of the recognition of a particular substance of interest by a biological unit of recognition (probe).…”

The increased awareness of the hazardous effects of polycyclic aromatic hydrocarbons (PAHs) has been the target of several studies in the current literature. PAHs are a group of organic molecules derived from petroleum that contains from two to seven aromatic rings in their structure that have been largely emitted to the environment from natural but especially anthropogenic sources. In this research, we reviewed the main aspects concerning the effects of PAHs in the environment with a special focus on the biosensing platforms recently developed to detect these pollutants. Herein, we reported the use of biosensors as an alternative to the expensive, time-consuming and laborious traditional techniques commonly employed to detect PAHs. Most of the examined literature referred to the use of antibodies and DNA as biological elements to fabricate the sensors, and the electrochemical and optical mechanisms comprised the preferred transduction techniques for this purpose. Among the 16 PAHs present in the priority list established by the United States Environmental Protection Agency (US EPA) with respect to the toxicity and abundance, B[a]P was the pollutant most studied by researchers in the field of biosensors, who found limits of detection in the order of micro molar. Overall, the reviewed biosensors presented significant promise for the reliable, selective and sensitive detection of PAHs in the ecosystem.
