HEALTH RISK ASSESSMENT OF POLYCYCLIC AROMATIC HYDROCARBONS IN BOBO CROAKER (Pseudotolithus .....

Thousands of Pseudotolithus elongatus died suddenly in the first quarter of 2020, indicating a high level of wastewater contamination. The goal of the study was to determine the risk of Polycyclic Aromatic Hydrocarbon (PAH) exposure to humans from P. elongatus exposed to pollutants in Bonny River. In two seasons (Wet season and Dry season), 36 P. elongatus and eighteen controls were collected from the Bonny River and examined for PAHs using Gas Chromatography - Flame Ionization Detector (GC-FID). The Dietary Daily Intake (DDI), carcinogenic potencies (B(A)Pteq), PAH4 index, Carcinogenic toxic equivalents (TEQ), and Excess Cancer Risk Index (ECR) were all used to estimate the risk of PAHs. In the rainy season, the DDI of PAHs is 1.4E-03 in Chrysene and Indeno (1,2,3) pyrene, and 1.1E-03 in the dry season. PAH4 levels were found to be 0.065 mg/kg in the rainy season and 0.23 mg/kg in the dry season, both of which are significantly higher than the EU standard of 0.03 mg/kg. Dibenzo (a,h)anthracene B(A)Pteq (6.2E-02 and 0.22) were similarly greater than the EU norm. TEQs were 0.23 mg/kg, and 6.5E-02 was higher than the SV of 5.55E-03 mg/kg, indicating possible toxicity. According to the findings of the current research, consuming Bobo Croaker (Pseudotolithus elongatus) from Bonny River poses a high risk of PAH exposure to humans.
