Pharmaceuticals in Coastal Waters: An UHPLC-TOF-MS Multi-Residue Approach
Leston, Sara; Freitas, Andreia; Rosa, João; Vila Pouca, Ana Sofia; Barbosa, Jorge; Reis-Santos, Patrick; Fonseca, Vanessa F.; Pardal, MiguelAnthropogenic chemical contamination represents a key stressor of natural environments with pharmaceuticals comprising a particular group of emerging pollutants with the potential to induce biological responses in non-target organisms. Therefore, an analytical method based on ultra-high-performance liquid chromatography coupled to time-of-flight tandem mass spectrometry (UHPLC-TOF-MS) was developed for estuarin...
Acoustic Telemetry Unravels Movements and Habitat Use Patterns of Juvenile Meag...
Marques, João P.; Almeida, Pedro R.; Moreira, Pedro; Reis-Santos, Patrick; Prista, Nuno; Costa, José L.; Domingos, Isabel; Alexandre, Carlos M.The meagre is among the largest Sciaenidae in the world (max: 230 cm, 103 kg), with a wide distribution range encompassing the NE and CE Atlantic Ocean and the Mediterranean Sea. The life cycle in Atlantic waters includes migratory movements from feeding and overwintering areas at sea to spawning and nursery areas in estuaries and coastal waters. However, significant spawning aggregations are only observed in f...
Effect Biomarkers of the Widespread Antimicrobial Triclosan in a Marine Model D...
Duarte, Bernardo; Feijão, Eduardo; Cruz De Carvalho, Ricardo; Matos, Ana Rita; Cabrita, Maria Teresa; Novais, Sara C.; Moutinho, ArianaThe present-day COVID-19 pandemic has led to the increasing daily use of antimicrobials worldwide. Triclosan is a manmade disinfectant chemical used in several consumer healthcare products, and thus frequently detected in surface waters. In the present work, we aimed to evaluate the effect of triclosan on diatom cell photophysiology, fatty acid profiles, and oxidative stress biomarkers, using the diatom Phaeoda...
Fluoxetine induces photochemistry-derived oxidative stress on Ulva lactuca
Feijão, Eduardo; Carvalho, Ricardo Cruz de; Duarte, Irina A.; Matos, Ana Rita; Cabrita, Maria Teresa; Utkin, Andrei B.; Caçador, IsabelEmerging pollutants impose a high degree of stress on marine ecosystems, compromising valuable resources, the planet and human health. Pharmaceutical residues often reachmarine ecosystems, and their input is directly related to human activities. Fluoxetine is an antidepressant, and one of the most prescribed selective serotonin reuptake inhibitors globally and has been detected in aquatic ecosystems in concentr...

Effects of glyphosate-based herbicide on primary production and physiological f...
Carvalho, Ricardo Cruz de; Feijão, Eduardo; Matos, Ana Rita; Cabrita, Maria Teresa; Utkin, Andrei B.; Novais, Sara C.; Lemos, Marco F.L.The use of glyphosate-based herbicides (GBHs) worldwide has increased exponentially over the last two decades increasing the environmental risk to marine and coastal habitats. The present study investigated the effects of GBHs at environmentally relevant concentrations (0, 10, 50, 100, 250, and 500 ug.L-1) on the physiology and biochemistry (photosynthesis, pigment, and lipid composition, antioxidative systems ...

L.The use of glyphosate-based herbicides (GBHs) worldwide has increased exponentially over the last two decades increasing the environmental risk to marine and coastal habitats. The present study investigated the effects of GBHs at environmentally relevant concentrations (0, 10, 50, 100, 250, and 500 μg·L−1) on the physiology and biochemistry (photosynthesis, pigment, and lipid composition, antioxidative systems ...

Ecotoxicological effects of the anionic surfactant Sodium Dodecyl Sulfate (SDS)...
Cruz de Carvalho, Ricardo; Feijão, Eduardo; Matos, Ana; Cabrita, Maria Teresa; Utkin, Andrei; Novais, Sara; Lemos, Marco; Caçador, Isabel; Marques, JoãoSodium Dodecyl Sulfate (SDS) is an anionic surfactant, extensively used in detergents, household and personal care products, as well as in industrial processes. The present study aimed to disclose the potential toxicological effects of SDS exposure under environmentally relevant concentrations (0, 0.1, 1, 3, and 10 mg L−1 ) on the physiology and biochemistry (photosynthesis, pigment, and lipid composition, anti...
