“…This could be attributed to the number of boats in jetties, as well as other dominating factors such as boat fuelling and maintenance. [46,47] The number of boat operations recorded during our study was in the order NS > OC > CS > SS, which matches with the trend observed for the variation in sediment. Consequently, it can be suggested that boating activities are the main source of sediment PHC around the jetty regions of the Chilika Lagoon.…”

“…However, the higher concentration (followed by NS) could be due to the source from boat painting activities and accidental spillage as observed at the Pathara jetty ( Figure 1) during sampling. Suratman et al [47] also observed higher total petrogenic hydrocarbon concentrations near boating areas of the Setiu wetland, South China Sea. Lower PHC in CS and OC could be due to mixing of sea water with lower PHC concentration, as reported by Panigrahy et al [17] for the Bay of Bengal.…”

Assessment of petroleum hydrocarbon (PHC) in the Chilika Lagoon, India, revealed a significant spatio-temporal variation in surface water (analysis of variance: n = 120, p < .01), whereas insignificant variation in sediment samples. The lagoon exhibited the highest PHC concentration during summer, attributed to higher boat activity and mixing of PHC from bottom sediment. For PHC in both the water of the lagoon and regions adjacent to jetties, the northern sector exhibited highest concentrations, followed by the southern, outer channels and central sectors, in order. The highest PHC level was due to the highest density of fishing boat operations and maintenance activities, as well as the resuspension of lake sediments across the shallowest region of the lagoon. The PHC found in the water and sediment in the jetty regions were relatively high in comparison to the rest of the lagoon, again attributed to the maintenance and operational activities of the motorised boats in the jetties. The sediment PHC concentration was ∼1000 times higher than the respective value for water, which could result from long-term deposition. The overall PHC concentration in the lagoon and jetties was found to be under the threshold limit and hence there is no risk to the existing biodiversity of the Chilika Lagoon. ARTICLE HISTORY

“…However, some studies were reported with lower values of TPH than obtained in this study in other parts of the world. Examples include water samples from Main Outfall Drain in Al-Nassiriya City/Southern Iraq [51], water samples from Setiu Wetland [60], Terengganu coastal waters from Malaysian west coast [55], and Dungun River basin water, Malaysia [23]. …”

Petroleum hydrocarbon status of the Buffalo River Estuary in East London, South Africa, was evaluated from January to May, 2016. Surface water and sediment samples were collected from five points in the estuary and extracted using standard methods. The extracts were subsequently analyzed by gas chromatography-flame ionization detection. Results showed that total petroleum hydrocarbon (TPH) varied from 7.65 to 477 μg/L in the water and 12.59 to 1,100 mg/kg in the sediments, with mean values of 146.50 ± 27.96 μg/L and 209.81 ± 63.82 mg/kg, respectively. Concentrations of TPH in the sediments correlated significantly with organic carbon (OC) in both seasons. TPH and OC levels were slightly lower in summer than in autumn in the two environmental matrices, and the average amount of TPH in the water samples collected from all the sampling stations was generally lower than the EU standard limit of 300 μg/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), indicating a serious impact of industrial growth and urbanization on the area, although the n-alkane ratios and indexes used for source tracking revealed excessive flow from both natural and anthropogenic sources.

“…Discharge of palm oil waste into the river systems was observed during the sampling periods. No studies have been carried out to date on the relationship between palm oil wastes and TPH concentration, as it was always associated with petroleum sources or products [9][10][11][12][13] . In addition, stations D7 and D8 which were located downstream of Dungun River basin, showed higher concentrations of TPH compared to the upstream stations (D1 to D4).…”
