In vitro bioaccessibility of macro and trace elements in biofortified and conve...
Barbosa, Vera; Anacleto, Patrícia; Maulvault, Ana Luísa; Oliveira, Helena; Marmelo, Isa; Ferraris, Francesca; Raggi, Andrea; Ventura, MartaBiofortification is a promising strategy to improve the nutrient profile of farmed fish but requires consideration of the nutrient bioaccessible fraction. In this study, the in vitro bioaccessibility of macro and trace elements was investigated in biofortified and conventional farmed gilthead seabream and common carp, also taking into account the effect of cooking (by steaming). Biofortification enhanced iodine...
Physicochemical properties of iodine and selenium biofortified Sparus aurata an...
Barbosa, Vera; Camacho, Carolina; Oliveira, Helena; Anacleto, Patrícia; Maulvault, Ana Luisa; Delgado, Inês; Ventura, Marta; Dias, Jorge; Ribeiro, LauraFish biofortification with natural ingredients like iodine-rich macroalgae and selenized-yeast is an excellent strategy to enhance the nutritional quality of farmed fish. This study aimed to assess the effect of frozen storage during 12-months on physicochemical quality of biofortified seabream (Sparus aurata) and carp (Cyprinus carpio). Frozen storage reduced iodine content in biofortified seabream fillets (17...
Enriched feeds with iodine and selenium from natural and sustainable sources to...
Barbosa, Vera; Maulvault, Ana Luísa; Anacleto, Patrícia; Santosa, Marta; Mai, Mónica; Oliveira, Helena; Delgadoe, Inês; Coelho, Inês; Barata, MarisaDeveloping tailor-made fortified farmed fish is a promising solution to overcome nutritional deficiencies and increase consumer confidence in these products. This study evaluated the supplementation of three fortified diets with I-rich seaweed and selenised-yeast on essential and toxic elements levels in gilthead seabream (Sparus aurata) and common carp (Cyprinus carpio). Fortified diets resulted in increased I...
Paralytic shellfish toxins and ocean warming: bioaccumulation and ecotoxicologi...
Barbosa, Vera; Santos, Marta; Anacleto, Patrícia; Maulvault, Ana Luísa; Pousão-Ferreira, Pedro; Reis Costa, Pedro; Marques, AntónioWarmer seawater temperatures are expected to increase harmful algal blooms (HABs) occurrence, intensity, and distribution. Yet, the potential interactions between abiotic stressors and HABs are still poorly understood from ecological and seafood safety perspectives. The present study aimed to investigate, for the first time, the bioaccumulation/depuration mechanisms and ecotoxicological responses of juvenile gi...
Polycyclic aromatic hydrocarbons bioaccessibility in seafood: Culinary practice...
dos Santos Fogaça, Fabíola Helena; Soares, Cristina; Oliveira, Marta; Alves, Ricardo N.; Luísa Maulvault, Ana; Barbosa, Vera L.; Anacleto, PatríciaThis work aimed to determine the effect of culinary practices on the contamination level and bioaccessibility of polycyclic aromatic hydrocarbons (PAHs) in seafood. The selected farmed seafood species (marine shrimp, clams and seaweed) were commercially available in Portugal. The mean concentrations of PAHs varied between 0.23 and 51.8 µg kg-1, with the lowest value being observed in raw shrimp and the highest ...
Antidepressants in a changing ocean: Venlafaxine uptake and elimination in juve...
Luísa Maulvault, Ana; Santos, Lúcia H.M.L.M.; Camacho, Carolina; Anacleto, Patrícia; Barbosa, Vera; Alves, Ricardo; Pousão Ferreira, PedroThe presence of antidepressants, such as venlafaxine (VFX), in marine ecosystems is increasing, thus, potentially posing ecological and human health risks. The inherent mechanisms of VFX uptake and elimination still require further understanding, particularly accounting for the impact of climate change-related stressors, such as warming and acidification. Hence, the present work aimed to investigate, for the fi...
Macro and trace elements in Paracentrotus lividus gonads from South West Atlant...
Camacho, Carolina; Rocha, A. Cristina; Barbosa, Vera L.; Anacleto, Patrícia; Carvalho, M. Luísa; Rasmussen, Rie R.; Sloth, Jens J.; Almeida, C. MarisaSea urchin represents one of the most valuable seafood product being harvested and explored for their edible part, the gonads or roe. This species is generally considered a sentinel organism for ecotoxicological studies being widely used in monitoring programs to assess coastal aquatic environments quality, because is directly exposed to anthropogenic contaminants in their habitat. In this context, the aim of t...
Fish energy budget under ocean warming and flame retardant exposure
Anacleto, Patrícia; Figueiredo, Cátia; Baptista, Miguel; Luísa Maulvault, Ana; Camacho, Carolina; Pousão-Ferreira, Pedro; Valente, Luísa M.P.Climate change and chemical contamination are global environmental threats of growing concern for the scientific community and regulatory authorities. Yet, the impacts and interactions of both stressors (particularly ocean warming and emerging chemical contaminants) on physiological responses of marine organisms remain unclear and still require further understanding. Within this context, the main goal of this s...
Assessing the effects of seawater temperature and pH on the bioaccumulation of ...
Luísa Maulvault, Ana; Camacho, Carolina; Barbosa, Vera; Alves, Ricardo; Anacleto, Patrícia; Fogaça, Fabiola; Kwadijk, Christiaan; Kotterman, MichielEmerging chemical contaminants [e.g. toxic metals speciation, flame retardants (FRs) and perfluorinated compounds (PFCs), among others], that have not been historically recognized as pollutants nor their toxicological hazards, are increasingly more present in the marine environment. Furthermore, the effects of environmental conditions (e.g. temperature and pH) on bioaccumulation and elimination mechanisms of th...
Integrated multi-biomarker responses of juvenile seabass to diclofenac, warming...
Luísa Maulvault, Ana; Barbosa, Vera; Alves, Ricardo; Anacleto, Patrícia; Camacho, Carolina; Cunha, Sara; Fernandes, José O.; Ferreira, Pedro PousãoPharmaceutical drugs, such as diclofenac (DCF), are frequently detected in the marine environment, and recent evidence has pointed out their toxicity to non-target marine biota. Concomitantly, altered environmental conditions associated with climate change (e.g. warming and acidification) can also affect the physiology of marine organisms. Yet, the underlying interactions between these environmental stressors (...
