“…The ETS assay is a useful metabolic indicator. Under stressful conditions, invertebrates may increase their metabolic activity to activate detoxifying and antioxidant defense mechanisms (Smolders et al 2004;Soucek and Dickinson 2012;Almeida et al 2015aAlmeida et al , 2015bCruz et al 2015). The fact that there were no significant ETS differences (p > 0.05) between sites suggests that contamination was not high enough to affect their metabolic and respiration activity.…”

To evaluate the potential impact of an urban wastewater-treatment plant on Ria Formosa coastal lagoon, a sentinel species, the clam Ruditapes decussatus, was exposed along a gradient of the effluent's dispersal for 1 mo. Three exposure sites were selected to study the responses of 3 biomarkers: electron transport system, acetylcholinesterase, and lipid peroxidation. As complementary data, morphometric measurements, condition index, and lipid and protein content were considered together with in situ physicochemical characterization of the sites (temperature, salinity, pH, and dissolved oxygen). Electron transport system activity levels were between 35.7 and 50.5 nmol O 2 /min g protein, acetylcholinesterase activity levels ranged from 2.6 to 3.8 nmol/min g protein, and lipid peroxidation ranged from 174.7 to 246.4 nmol malondialdehyde/g protein. The exposure sites shaped the response not only of biomarkers but also of "health" parameters (protein, lipids, and condition index). Lipid peroxidation was the most responsive biomarker also associated with electron transport system, especially at the closest site to the urban wastewater-treatment plant. Because of the presence of complex mixtures of contaminants in urban effluents, biomarker responses can provide valuable information in environmental assessment. However, it is vital to identify all biological and ecological factors induced by the natural life cycle of clams. Abiotic factors can mask or overlap the response of biomarkers and should be considered in a multibiomarker approach.

“…Os ensaios para verificar a qualidade adsortiva do carvão foram realizados em três faixas de pH: neutra (7,3), básica (11,6) e ácida (2,6), ajustados com soluções de NaOH (1 N) e HCl (1 N), obtendo assim a melhor faixa de pH para adsorção em 120 min com tomadas de amostra a cada 20 min. A proporção foi de 0,5 g de carvão ativado para 100 mL de solução de cafeína (Cafeína anidra PA) a 25 mg/L.…”

Activated carbon is used like adsorbent in removing gaseous and liquid pollutants besides purification and chemical recovery. However, its production has a high cost and has sought alternative precursors materials such as coffee grounds. The objective of this study was to determine the removal of caffeine in aqueous solution using activated carbon produced from coffee grounds by adsorption. The coffee grounds was impregnated with ZnCl2 and activated in aluminum capsules where it was used alcohol cotton and put fire to consume the oxygen inside. The adsorption test was performed with concentration of caffeine of 25 mg/L, 0.5 g of activated carbon in 100 mL samples, leaving the suspension under stirring for 120 minutes, in acid, neutral and basic pH. The pH range which obtained better removal was the neutral, removing 99.04% caffeine in 40 minutes. The kinetic test was performed in 20 minutes with the intraparticle model being the best fit.
