Abstract A profound analysis of A. tripolium photochemical traits under salinity exposure is lacking in the literature, with very few references focusing on its fatty acid profile role photophysiology. To address this, deep processes were evaluated by Pulse Amplitude Modulated (PAM) Fluorometry coupled a discrimination leaf profile. Plants exposed to 125–250 m NaCl showed higher light harvesting efficiencies and lower energy dissipation rates. exposure, there evident damage oxygen evolving...
Changes in biomass and photosynthesis of a diatom-dominated microphytobenthos (MPB) intertidal community were studied over diel emersion period using combination O2 scalar irradiance microprofiling, variable chlorophyll (Chl) fluorescence, pigment analysis. The MPB the photic zone (0-0.5 mm) sediment exposed to low (150 μmol photons m(-2) s(-1)) showed >2-fold increase during first hours period, reaching >0.2 mg Chl cm(-3). Concentrations started decrease half-way through almost 2 h before...
Increasing input of Metal Engineered Nano Particles (MeENPs) in marine ecosystems has raised concerns about their potential toxicity on phytoplankton. Given the lack knowledge MeENPs impact these important primary producers, effects Copper Oxide (CuO) ENPs growth, physiology, pigment profiles, fatty acid (FA) metabolism, and oxidative stress were investigated model diatom Pheodactylum tricornutum , to provide suitable biomarkers CuO ENP exposure versus its ionic counterpart. Diatom growth...
The high demand and economic relevance of cephalopods make them prone to food fraud, including related harvest location. Therefore, there is a growing need develop tools unequivocally confirm their capture Cephalopod beaks are nonedible, making this material ideal for traceability studies as it can also be removed without loss commodity value. Within context, common octopus (Octopus vulgaris) specimens were captured in five fishing areas along the Portuguese coast. Untargeted multi-elemental...
In the context of expanding fish production and complex distribution chains, traceability, provenance food safety tools are becoming increasingly important. Here, we compare elemental fingerprints gilthead seabream (Sparus aurata) muscle from wild different aquaculture productions (semi-intensive earth ponds intensive sea cages two locations) to confirm their origin evaluate concentrations elements with regulatory thresholds (Cu, Hg, Pb Zn). Using a chemometric approach based on...
We discuss the development of laser induced fluorescence sensors and their application in evaluation water pollution physiological status higher plants algae. The were built on basis reliable robust solid-state Nd:YAG lasers. They demonstrated good efficiency in: i) detecting characterizing oil spills dissolved organic matter; ii) evaluating impact stress (cork oak, maritime pine, genetically modified Arabidopsis); iii) tracking biomass changes intertidal microphytobenthos; iv) mapping...
The Water Framework Directive (WFD) aims at evaluating the ecological status of European coastal water bodies (CWBs). This is a rather complex task and first requires use long-term databases to assess effect anthropogenic pressure on biological communities. An in situ dataset was assembled using concomitant biological, i.e., chlorophyll (Chl a) environmental data, covering years from 1995 2014, enable comprehensive assessment eutrophication Western Iberia Coast (WIC). Given temporal gaps...
Provenance and traceability are crucial aspects of seafood safety, supporting managers regulators, allowing consumers to have clear information about the origin products they consume. In present study, we developed an innovative spectral approach based on total reflection X-ray fluorescence (TXRF) spectroscopy identify provenance a case study for five economically relevant marine species harvested in different areas Atlantic Portuguese coast: three bony fish-Merluccius merluccius, Scomber...
