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 ...

Making sense of light: the use of optical spectroscopy techniques in plant scie...
Cavaco, A. M.; Utkin, Andrei B.; Marques da Silva, Jorge; Guerra, RuiAs a result of the development of non-invasive optical spectroscopy, the number of prospective technologies of plant monitoring is growing. Being implemented in devices with different functions and hardware, these technologies are increasingly using the most advanced data processing algorithms, including machine learning and more available computing power each time. Optical spectroscopy is widely used to evalua...
Photosynthetic pigment laser-induced fluorescence indicators for the detection ...
Cabrita, Maria Teresa; Gameiro, C.; Utkin, Andrei B.; Duarte, Bernardo; Caçador, Isabel; Cartaxana, PauloThis work reports changes on cell number, growth rate, trace element content, chlorophyll a (Chl a) and carotenoid concentrations, and laser-induced fluorescence (LIF) spectra of Phaeodactylum tricornutum exposed to Co, Ni, Cu, Zn, Cd, Hg, Pb, and a mixture of all elements combined (Mix). The total levels of trace elements associated with the cells were significantly higher in the exposed than in control ones. ...
Characterisation of estuarine intertidal macroalgae by laser-induced fluorescence
Gameiro, Carla; Utkin, Andrei B.; Cartaxana, PauloThe article reports the application of laser-induced fluorescence (LIF) for the assessment of macroalgae communities of estuarine intertidal areas. The method was applied for the characterisation of fifteen intertidal macroalgae species of the Tagus estuary, Portugal, and adjacent coastal area. Three bands characterised the LIF spectra of red macroalgae with emission maxima in the ranges 577–583 nm, 621–642 nm ...
