A principal component analysis (PCA) of 1H NMR spectra beers differing in production site (A, B, C) and date is described, to obtain information about composition variability. First, lactic pyruvic acids contents were found vary significantly between sites, good reproducibility dates being for but not sites B C beers. Second, clearly distinguished by the predominance linear dextrins, while richer branched dextrins. Carbohydrate poorer with dextrin branching degree varying significantly....
Esca is a destructive disease that affects vineyards leading to important losses in wine production. Information about the response of Vitis vinifera plants this scarce, particularly concerning changes plant metabolism. In order study metabolic affected by esca, leaves from both infected and non-affected cordons V. cv. Alvarinho (collected Vinho Verde region, Portugal) were analysed. The metabolite composition with visible symptoms [diseased (dl)] asymptomatic [healthy (hl)] was evaluated 1D...
Sample pretreatment is one of the most important steps in guaranteeing success a chromatographic analysis. The selected methodology must ensure simultaneously that sample “clean” enough for analysis and target analytes are not removed process. This can be especially difficult when working with complex matrices such as natural waters wastewater. For pharmaceutical active compounds (PhACs) by solid-phase extraction (SPE) followed ultra-high performance liquid chromatography coupled to tandem...
The profile of pharmaceutical active compounds (PhACs) in two UWWTP was evaluated. potential behaviour PhACs on agriculture soils evaluated based their physicochemical properties and soil pH.
The control of pharmaceutical compounds (PhCs) in urban wastewater treatment plants (WWTPs) is an issue health and environmental relevance, expected to become mandatory the European Union beyond, but studies at full scale are still scarce. A long-term (2.5-year) full-scale study addressing practical strategies for controlling PhCs was conducted two activated sludge WWTPs with nitrification (BEI A2O process; FNW oxidation ditch). results showed similar removal patterns both – some most...
The occurrence of a representative range pharmaceutical compounds (PhCs) in urban wastewaters was studied two Portuguese water-scarce regions (Lisbon great area, and Faro – Algarve), involving 55 sampling campaigns during 2.5 years. results show 16 PhCs (out the 24 analysed) were quantified all samples, with similar concentrations both wastewaters. To understand to what extent seasonality affects PhC occurrence, statistical analysis conducted, daily maximum air temperature identified as key...
Untargeted Nuclear Magnetic Resonance metabolomics was employed to study the effects of warming conditions (17-21 °C) and exposure 17-α-ethinylestradiol (EE2) on polar metabolome Ruditapes philippinarum clams, identify metabolic markers for monitoring/prediction deviant environmental conditions. Warming alone triggered changes in alanine/aspartate/glutamate, aromatic amino acids, taurine/hypotaurine homarine/trigonelline pathways, as well energy metabolism, suggesting osmoregulatory...
In a significant number of European countries, the need for providing appropriate treatment effluents small rural communities is still especially relevant. fact, in countries like Portugal, Spain, and many others, amounts investment will be addressed next few years to construction Wastewater Treatment Plants (WWTP). The problems faced when constructing operating WWTP serving may relevant energy labour costs are relatively high, or visual impact on surrounding areas negative. Sustainable...
In water treatment plants (WTPs), chemical agents, such as chlorine and ozone, might react with organic matter anthropogenic contaminants, forming a high diversity of disinfection by-products (DBPs). Due to the potential toxicological effects, identification unregulated DBPs (UR-DBPs) is critical help managers in selection effective processes, contributing improving safety plans. Given limited validated analytical methods detect UR-DBPs, here we developed new multi-residue gas chromatography...
