“…These results indicate high species variability in relation to different feeding preferences, the consistent Cd, Cr, Zn, Cu, As and Hg on the PCA indicated homogeneous anthropogenic pollution sources for these six metals. Cabrini 39 found that fish with different trophic guilds in different regions of Rio de Janeiro in Brazil showed different metal enrichment results, mainly because the metal content of fish food is different in regions with different pollution levels. Therefore, metal accumulation is mainly related to the level of metal content in fish food.…”

“…Cu and Zn are micronutrients in living organisms, high contents were found in each fish species. They are regulated by the metabolism and constitute enzymes and hemocyanin, which affect the proper course of many life processes 39 , 40 . Chromium, which was nearest to the cluster of copper and zinc, has no known biological function but is usually toxic to organisms 41 , 42 .…”

Xincun Lagoon is an important fishing area in northern Hainan Island, China. It has long been exposed to pollutants from local sewage, breeding cages and fishing boats, resulting in serious pollution threats to the survival of fish. In this study, we examined the concentrations of seven trace metals (Cu, Pb, Zn, Cd, Hg, As and Cr) in sixteen economic fish species collected from Xincun Lagoon and their exposed environment (water and sediment). The concentrations of Pb and Zn in the water column were higher than the safety threshold stipulated by Chinese legislation, while the contents of all examined metals in the sediment and fish species were lower than the legislative thresholds set by China and international organizations. The contents of trace metals in the fish species in high trophic levels or those that prefer to live in/on the sediment layer were significantly higher than those in other trophic levels and pelagic/subbenthic fish, these species had homogeneous anthropogenic pollution sources for Cu, Zn, Cd, Hg and As. Our results show that the trace metal contents in fish were mainly affected by trophic level and habitat preference. The contribution of metal exposure from the sediment to metal accumulation in fish was lower than that in water, especially for the Cd and Hg in the sediment. These results provide valuable information for further understanding the species-specific patterns of metal accumulation in fish and the development of targeted conservation measures for the environment and fish consumers.

“…Brazilian beaches have been jeopardized by oil spills (Marques et al, 2017;Sills et al, 2020;da Rosa, 2022), sewage discharges (Roth et al, 2016), marine litter (Neves et al, 2022), overfishing (Bender et al, 2014), chemical contamination (Cabrini et al, 2017;Cabrini et al, 2018;Ragagnin and Turra, 2022), trampling and vehicles traffic (Bom and Colling, 2020;Santos et al, 2021b;Bom and Colling, 2022;Santos et al, 2022) and coastal urbanization (Reĝo et al, 2018;Corte et al, 2022;Laurino et al, 2022;Shah Esmaeili et al, 2022). Furthermore, researchers have shown that urbanization may increase parasitism in invertebrates and fishes Amaral et al (2016) and Fanini et al (2020) combined into the four broad topics, and considerations on the advances (or lack of) in each of these areas during the previous decade.…”
