“…In addition to this role, HMs also affect the development of bivalves. During feeding, bivalves in ecosystems contaminated with HMs can bioaccumulate them through water filtration ( Wang and Lu, 2017 ; Max Blanc et al., 2019 ; Yuan et al., 2020 ). The incorporation of these metal compounds also depends on the physical conditions of the metal and the physicochemical factors of the environment ( Wang and Rainbow, 2005 ; Tapia et al., 2010 ; Cardwell et al, 2013 ).…”

Anthropogenic pollution has a huge impact on the water quality of marine ecosystems. Heavy metals and antibiotics are anthropogenic stressors that have a major effect on the health of the marine organisms. Although heavy metals are also associate with volcanic eruptions, wind erosion or evaporation, most of them come from industrial and urban waste. Such contamination, coupled to the use and subsequent misuse of antimicrobials in aquatic environments, is an important stress factor capable of affecting the marine communities in the ecosystem. Bivalves are important ecological components of the oceanic environments and can bioaccumulate pollutants during their feeding through water filtration, acting as environmental sentinels. However, heavy metals and antibiotics pollution can affect several of their physiologic and immunological processes, including their microbiome. In fact, heavy metals and antibiotics have the potential to select resistance genes in bacteria, including those that are part of the microbiota of bivalves, such as Vibrio spp. Worryingly, antibiotic-resistant phenotypes have been shown to be more tolerant to heavy metals, and vice versa, which probably occurs through co- and cross-resistance pathways. In this regard, a crucial role of heavy metal resistance genes in the spread of mobile element-mediated antibiotic resistance has been suggested. Thus, it might be expected that antibiotic resistance of Vibrio spp. associated with bivalves would be higher in contaminated environments. In this review, we focused on co-occurrence of heavy metal and antibiotic resistance in Vibrio spp. In addition, we explore the Chilean situation with respect to the contaminants described above, focusing on the main bivalves-producing region for human consumption, considering bivalves as potential vehicles of antibiotic resistance genes to humans through the ingestion of contaminated seafood.

The presence of cadmium (Cd) in Latin American produced food has been in the spotlight in recent years. Regarding food safety, this element can be toxic to humans at low exposure levels, and its monitoring is a question of public health. Cadmium concentrations from different sources, such as water, soil, sediments, food and beverages were examined and discussed to address the non-occupational exposure of the Latin American population. A literature review was conducted, which considered publications from 2015 to 2020 and available in the ScienceDirect and PubMed databases. Twenty-eight papers were considered for Cd in water, forty-nine for Cd in soil and sediments, and eighty-six for Cd in food. We identify and discuss factors affecting Cd environmental behavior and bioaccumulation, the main species used in monitoring studies, and the necessity for future research. Brazil and Mexico are the countries with the most available information, whereas for some countries in Central America, no information was found. The Cd levels in food examined in these studies (mostly fish and cacao) were generally below the established maximum levels, indicating a low risk. When considering the presence of Cd in food, water, and soil, Cd fractionation and chemical speciation studies are fundamental to understand which Cd species are the most toxic. In turn, studies on bioaccessibility and bioavailability of Cd in food are also needed for more adequate risk assessment but they are currently scarce in all of Latin America.
