“…This wide concentration range has also been reported in other studies (Pulster et al, 2020) and may have occurred due to the use of individuals of different species, sexes, sizes, and weights (Tables 1 and 2). Nevertheless, such levels agree with data described in previous studies in SB and its estuary (de Albergaria- Barbosa et al, 2017Barbosa et al, , 2018 and can be compared with other urban coastal regions (McCain et al, 1990;Escartín and Porte, 1999b;da Silva et al, 2006;Silva et al, 2021).…”

“…Determining PAH metabolites in fish bile is a useful biomarker of contamination and studies have shown that its presence correlates with recent exposure to PAHs (Collier and Varanasi, 1991;Britvić et al, 1993;Upshall et al, 1993;Anulación et al, 2020). This determination has been used in international monitoring programs (Fuchsman et al, 2001;HELCOM, 2013;Kammann et al, 2017) and environmental studies to evaluate the bioavailability of PAHs (Krahn et al, 1984(Krahn et al, , 1986(Krahn et al, , 1993Porte, 1999a, 1999b;da Silva et al, 2006;Pulster et al, 2020;Snyder et al, 2020;Silva et al, 2021). The increase in anthropogenic activity over the last 100 years in this region contributed to the release of contaminants into the bay (Martins et al, 2011).…”

Bioavailability of polycyclic aromatic hydrocarbons in Santos Bay (Brazil) and its adjacent continental shelf

This study evaluated the bioavailability of polycyclic aromatic hydrocarbons (PAHs) in Santos Bay (SB) and the adjacent Santos Continental Shelf (SCS) in Brazil. Biliary metabolites were measured in several fish species to establish a baseline for future monitoring programs. Bile samples from different species of fish were collected monthly from July to December 2005 in SB, and in August 2005 and February 2006 on SCS. Metabolite concentrations were determined using high-performance liquid chromatography with fluorescence detectors. Naphthalene, phenanthrene, and benzo[a]pyrene metabolite concentrations ranged from 24 to 810 µg g -1 of bile, 1.8 to 68 µg g -1 of bile, and below the limit of quantitation to 1.3 µg g -1 of bile, respectively. Despite its high concentrations, the levels of naphthalene metabolites were in regions of low-contamination, while benzo[a]pyrene metabolite were in the same range as those reported in moderately contaminated areas, which may indicate pyrolytic contamination by PAHs. No significant differences in the metabolite concentrations were found between the SB and the SCS samples or during the periods of collection. Future studies with a single biomonitoring species should be conducted, considering age, sex, and feeding condition of the individuals. The metabolite data presented in this study is an important baseline information for this urbanized region, which hosts several sources of contaminants.
