“…Discharges of petroleum re nery industries and land-based wastewater are also common in this station. Further, oil spill occurred due to the oil tanker ship accident at Ennore port (near Chennai harbour) in January 2017 which released more than 100 tonnes of heavy fuel oil (Sivagami et al 2019). Other stations such as S10, S11 & S15 which are located near shing harbours also showed a high level of TPH in the sediments (Fig.…”

The spatial distribution of Total Petroleum Hydrocarbons (TPH) were analyzed in the seawater and sediment samples collected from 27 locations along the Southeast coast of India. A rst-time assessment study was carried out on the distribution of TPH in both water and sediments for the entire coastline of Tamil Nadu. The concentration of TPH in seawater showed large spatial variation ranging from Below Detection Level (BDL) to 47.5μg/L and 0.01 to 53.12μg/L in the surface and bottom waters, respectively. TPH levels exceeded the regulatory limits speci ed by FAO, China's Marine Monitoring Standards and the European Community in the seawater samples of Thoothukudi harbour (S2 station). TPH values in sediment were between 2.33-30.07μg/g and their levels remained below the Marine Sediment Quality Standard (500μg/g). The results showed that seawaters of southern stations were comparatively more polluted with TPH. The spatial pro le of TPH in sediments were contrasting to that observed for seawater. Higher TPH values were observed in the northern region than southern. TPH contents showed a nity to clay and silt with a strong positive correlation with clay (R2=0.776; P<0.001), silt (R2=0.648; P<0.001) and negative correlation (R2=0.753; P<0.001) with sand. ANOVA analysis demonstrated a signi cant difference (F=11.75; p<0.01) between the TPH concentrations of water and sediments. Non-metric multidimensional scaling (nMDS) was performed to determine the similarity among sampling stations that formed ve crusted groups. Sediment along the southeast coast can be categorised as slightly polluted with respect to TPH as per the ATSDR standards.

“…Similarly, the oil spill in the coastal waters of Ennore near Chennai, India, has been documented to reduce water quality and 4 impact marine biota including phytoplankton, zooplankton, benthic communities and vertebrates like fishes and sea turtles (Begum et al, 2022). Although the hazards associated with such oil contaminations are often assessed by measuring total petroleum hydrocarbon (TPH) concentrations in the affected environments (Sammarco et al, 2013;Sivagami et al, 2019), there is a lack of studies focusing on the risks posed by individual PHs.…”

Petroleum hydrocarbons (PHs) are compounds composed mostly of carbon and hydrogen, originating from crude oil and its derivatives. PHs are primarily released into the environment through the diffusion of oils, resulting from anthropogenic activities like transportation and offshore drilling, and accidental incidents such as oil spills. Once released, these PHs can persist in different ecosystems and cause long-term detrimental ecological impacts. While the hazards associated with such PH contaminations are often assessed by the concentrations of total petroleum hydrocarbons in the environment, studies focusing on the risks associated with individual PHs are limited. Here, we leveraged different network-based frameworks to explore and understand the adverse ecological effects associated with PH exposure. First, we systematically curated a list of 320 PHs from published reports. Next, we integrated biological endpoint data from toxicological databases, and constructed a stressor-centric adverse outcome pathway (AOP) network linking 75 PHs with 177 ecotoxicologically-relevant high confidence AOPs within AOP-Wiki. Further, we relied on stressor-species network constructions, based on reported toxicity concentrations and bioconcentration factors data for 80 PHs and 28 PHs, respectively, and found that crustaceans are documented to be affected by many of these PHs. Finally, we utilized the aquatic toxicity data within ECOTOX to construct species sensitivity distributions for polycyclic aromatic hydrocarbons (PAHs) prioritized by the US EPA, and derived their corresponding hazard concentrations (HC05) that protect 95% of species in the aquatic ecosystem. Overall, this study highlights the importance of using network-based approaches and risk assessment methods to understand the PH-induced toxicities effectively.
