Background and Aim: The coastal waters of Hormozgan province are affected by the environmental pollution of the Persian Gulf due to oil and gas industries. The present study aimed to bio-monitor pollutants in Amiantis umbonell (oysters), Fenneropenaeus merguiensis (shrimp), Pseudorhombus elevatus (fish), selected as bioindicators of this area.
Methods: Sampling was performed from 8 selected stations on the coast of Hormozgan in summer and winter 2018. Thirty samples of Amiantis umbonella, 15 of Fenneropenaeus merguiensis, and 15 of Pseudorhombus elevatus were collected. Sampling and anlayses were performed according to standard methods of Manual of oceanographic observations and pollutant analyses methods (MOOPAM). Gas Chromatography-Mass Spectrometry (GC-Mass) was used to measure the PAHs, and AAS (Atomic Absorption Spectrophotometry) was used for measuring lead and cadmium.
Results: Finding showed that in fish muscle, there was no lead (0.45±0.1) or cadmium (0.07±0.01) contamination, but that there was moderate contamination of PAH (998 ± 1.0). The muscle and shell of shrimp had high levels of contamination with lead (4.91±0.7), (4.31±0.9) and PAH (1505±1.0), (1335±1.0) and low infection (1.01±0.6) and moderate cadmium levels (2.78 ± 0.6). Oyster soft tissue was moderately contaminated with lead (2‒5) and PAH (380±0.1) but there was no evidence of cadmium contamination (≥0.5). Overall, cadmium contamination (≥0.5) in the samples was low, but contamination with lead (> 3) and PAH (426±1.0) were moderate to high.
Conclusion: The findings of this study indicate that the measured concentrations of heavy metal elements and PAHs in fish, shrimps and oyesters are more than the recommended values and, therefore these species should be consumed with cautioun.
