“…The analysis on seasonality shows that PAH concentrations tend to be higher in specimens sampled in cold months (October-March), and this trend is statistically significant in both Mediterranean mussel and Manila clam, confirming what several studies, including those in this database, found independently [8,16,19,29,32,41].…”

“…Over the years, several studies have investigated the levels of PAHs in seafood caught in the Adriatic [12,[20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35], Ionian [9,20,34,[36][37][38][39], and Tyrrhenian Seas [7,14,16,17,19,30,[40][41][42][43][44][45][46][47][48][49][50], with the aims of monitoring the environmental status of particularly impacted areas [39,48], improving the knowledge of factors influencing PAHs levels in marine species [12,35], and, ultimately, informing decisionmakers when it comes to fixing the limits to PAH levels in fishery products [9].…”

Meta-Analysis of a New Georeferenced Database on Polycyclic Aromatic Hydrocarbons in Western and Central Mediterranean Seafood

et al. 2022

The aim of this work was to collect and harmonize the results of several studies achieved over the years, in order to obtain a database of georeferenced observations on polycyclic aromatic hydrocarbons (PAHs) in Western and Central Mediterranean seafood. For each observation, some information on the taxonomy and the ecology of the sampled species are reported, as well as details on the investigated hydrocarbon, and spatial and temporal information on sampling. Moreover, two health risk indexes were calculated for each record and included in the database. Through several statistical methods, we conducted a meta-analysis of the data on some of the species in this database, identifying trends that could be related to the biology of the investigated organisms, as well as to the physico-chemical properties of each hydrocarbon and to the oceanographic characteristic of this part of the Mediterranean. The analysis of the data showed that, at a consumption rate like the one typical of the Italian population, seafood caught from the area considered in the present work seems to pose a minimal risk to health. However, we also found evidence of an increasing trend of PAH concentrations in Mediterranean mussels, pointing to the need for constant monitoring.

Benzo [a]pyrene (BaP) is widely used as a reference compound when studying the toxicity of Polycyclic aromatic hydrocarbons (PAHs) to natural communities. In this study, 15d after exposure to BaP at the nominal concentrations of 5, 1 and 0.2 μg/L, liver, gill and mantle tissues of Crassostrea gigas and Mytilus coruscuswere taken for BaP uptake assessment, and Cytochrome P450 (CYP450) gene expression level and 7-ethoxyresorufifififin O-deethylase (EROD) activity testing, respectively. CYP450 gene expression level and EROD activity increased significantly with the increase of BaP exposure concentrations. The Significant correlations between BaP uptake and both CYP450 gene expression level and EROD activity indicates that they can be used as a suitable tools for the study of comprehensive levels of biomarker exposed to PAH. There were significant differences in the measurement results of these tissue antioxidant defenses parameters between different treatments.

“…It is distributed widely along the coasts of the Pacific to the Indian Ocean, including China, and the second most important commercially cultured marine bivalve species (Leppäkoski et al, 2002; Ruano et al, 2015; Tan et al, 2020; Zuo et al, 2020). Ruditapes philippinarum has been frequently used to indicate environmental pollution (laboratory and field studies; Almeida et al, 2021; Cacciatore et al, 2018; Strehse & Maser, 2020; Sturla Lompré et al, 2021). Previous studies have shown that PFOA is the predominant PFAS found in bivalves, especially in R. philippinarum (M. Guo et al, 2019).…”

Polyfluorinated alkylated substances are recognized as an important class of pollutants in marine environments. Bivalves are good model organisms for evaluating the toxicity of pollutants and monitoring marine environments. In the present study, immunotoxicity of perfluorooctanoic acid (PFOA) was investigated by measuring biomarkers of the immune profile of Ruditapes philippinarum. In bivalves, hemocytes are an important component of the immune system. Thus, hemocyte proliferation, phagocytosis, cell viability, and immune enzyme activities, which have been applied as marine pollution bioindicators, were identified and observed for changes after exposure to PFOA in R. philippinarum. Based on the integrated biomarker responses method, we selected five biomarkers to evaluate PFOA risk at the multibiomarker level. In addition, the histopathological alterations of hemocytes in bivalves were used as indexes of the response to environmental stress. The subcellular structure of the hemocytes in R. philippinarum changed significantly with PFOA exposure, including hemocyte and nucleus morphological changes, organelle dissolution, cytomembrane and karyotheca swelling, and cytoplasm vacuolization. The present study verifies PFOA immunotoxicity to R. philippinarum at different levels and the integrated assessment of stress levels caused by PFOA in marine environment. Our results will provide new insights into evaluating adverse effects of PFOA and monitoring marine ecosystem. Environ Toxicol Chem 2022;41:426–436. © 2021 SETAC
