“…The highest concentrations recorded in the surface and bottom waters were obtained at Woody Cape in summer (February) and St Croix in autumn (May), respectively. This could be attributed to urban discharges and vehicle emission from Port Elizabeth metropolis, recurrent industrial pollution from the two harbours, Coega Industrial Development Zone (IDZ) and factories in the neighbourhood of Swartkops River [ 31 , 33 , 35 , 77 , 78 ]. This is because the unresolved complex mixture (UCM) which is an indication of contamination from petroleum origin was below the detection limit at the two instances suggesting pollution from other anthropogenic sources [ 15 ].…”

Petroleum hydrocarbon profiles of water and sediment samples of Algoa Bay in the Eastern Cape Province of South Africa were assessed using standard analytical procedures. Water (from surface and bottom levels) and sediment samples were collected from five locations in the bay from February to June 2016. Extraction of the petroleum hydrocarbons from the water and sediment samples collected was achieved using liquid-liquid and Soxhlet extraction techniques, respectively, followed by column clean up. Target compounds were analytically determined with gas chromatography–flame ionization detector (GC-FID) and quantified by integrating the areas of both the resolved and unresolved components. Physicochemical properties of the water samples were also determined on site using a SeaBird 19plusV2 CTD SBE 55 device. Estimated limit of detection, limit of quantitation and relative standard deviation for the 35 n-alkane standards ranged from 0.06 to 0.13 μg/L, 0.30 to 0.69 μg/L and 3.61 to 8.32%, respectively. Results showed that total petroleum hydrocarbon (TPH) varied from 45.07 to 307 μg/L in the water and 0.72 to 27.03 mg/kg in the sediments. The mean concentrations of TPH in both the water and sediment samples from Algoa Bay revealed a slight level of pollution. The diagnostic indices used showed that the hydrocarbons in the area were from both biogenic and anthropogenic sources. Hence, there is need for adequate regulation and control of all activities contributing to the levels of petroleum hydrocarbon in the marine environment for the safety of human, aquatic and wild lives in the area.

“…The levels of TPH was reported for groundwater samples (1352-12,110 µg/L) collected from some communities in Niger Delta, Nigeria were found to be high (Alinnor et al, 2014) while surface water from Ubeji in Warri, Nigeria contain 73,500 µg/L of TPH (Adewuyi et al, 2011). Other regions around the world including Strait of Johor, in Peninsular, Malaysia reported 25-2,795 µg/L (Suratman, 2013) and Deepwater Horizon, Gulf of Mexico contains 60,000-260,000 µg/L of TPH (Sammarco et al, 2013). However, other studies have reported lower values of TPH than obtained in this study, these include water samples from Dungun River basin water, Malaysia was 12-41 µg/L (Suratman, 2013) and Levantine Basin, Israeli Coastline was 19-88 µg/L (SOGRLI, 2014).…”

The total petroleum hydrocarbon content in surface water and sediment of Qua Iboe River, Akwa Ibom State, Nigeria was assessed by randomly collecting samples from five sampling points of the study area and from a control site. The samples were extracted with dichloromethane (DCM) by liquid-liquid partition for water and Soxhlet extraction for sediments followed by subsequent clean up on column chromatography and analyzed by gas chromatography-flame ionization detection (GC-FID) for the determination of total petroleum hydrocarbons (TPH). The results showed variation of total petroleum hydrocarbon (TPH) content from 90 to 250 µg/L in the water and 270 to 830 mg/kg in the sediments, with mean value of 168.33±59.29 µg/L and 606.83±229.48 mg/kg respectively. The average amount of TPH in the water samples collected from all the sampling points was generally lower than the EU standard limit of 300 g/L. However, the levels in the sediments exceeded the EGASPIN target value (50 mg/kg) for mineral oil but were below the intervention value (5,000 mg/kg), this indicates a serious impact of oil industrial activities on the area. Hence, our findings have indicated evidence that Qua Iboe River is under pollution threat and underscore the need for early remediation if adverse health defects are to be prevented.

“…The most commonly used extraction method for TPHC in aqueous samples is the EPA 3510 liquid-liquid extraction [5,50,51]. Other available methods include continuous liquid-liquid extraction [11], solid phase extraction [51], vortex extraction [52], and microextraction [53].…”

Several methods of extraction and analytical determination for total petroleum hydrocarbons (TPHCs) in aqueous and solid samples are reviewed. Infrared spectroscopy is one of the efficient methods that are being replaced today pursuant to getting rid of some halogenated solvents classified as ozone-depleting substances. The gravimetric method which uses n-hexane as an extraction solvent for the determination of oil and grease, as well as the nonpolar materials, has become a preferred choice, despite being not suitable for volatiles because of the mandatory evaporation step. Other frequently used methods include gas chromatography with a flame ionization detector (FID) or mass spectrometric detector (MSD) which has the capacity to reveal the type of hydrocarbons present and is applicable to both volatile and semivolatile samples. Ultraviolet fluorescence is another method that is available both as a portable field device and as off-site laboratory equipment. Each of the methods has its own advantages and disadvantages; hence, the choice of method is guided by the type of data needed as discussed in detail in this review. The distribution of TPHC in water and sediments across the globe and the factors influencing the distribution were also reviewed.
