“…Caffeine is consumed in large amounts in beverages and in a lesser proportion in the analgesics form; however, its presence has been detected in different types of water: wastewaters (Sweden, Paxe´us, 1996;Spain, Matamoros, 2008); surface waters (Czech Republic, Franke et al, 1995; in the United States, Gardinali and Zhao, 2002;Ontario and Erie lakes in Canada, Metcalf et al, 2003;Spain, Huerta-Fontela et al, 2008); seawaters (Canada, Weigel et al, 2002;Comeau et al, 2008); and in groundwater (Spain, Teijon et al, 2010). In spite of this, the research over the distribution of caffeine in the aquatic environment initiated a few years ago, and it is found in rivers and aquifers in low concentrations in order of ng/L to mg/L.…”

Presencia de productos farmacéuticos y de cuidado personal en aguas residuales domésticas y su eliminación en sistemas de tratamiento anaerobios: tanque séptico -filtro anaerobio de flujo ascendente ABSTRACTIn several countries around the world, Pharmaceutical and Personal Care Products (PPCPs) exist in aquatic environments, a fact that increases the awareness within the scientific community with respect to their possible fate and environment effects. This research presents a preliminary monitoring of use, consumption and presence of PPCPs in wastewater from a treatment plant in a rural area of Pereira (Colombia). Domestic sewage is treated in a septic tank followed by an Up-Flow Anaerobic Filter and its effluent is discharged into the Otún River, upstream of the water intake of the supply system of the city. The compounds monitored in this research included ibuprofen, naproxen, diclofenac, aspirin, ketoprofen, caffeine, galaxolide, tonalide and dihydrojasmonate. An adapted method of multi-residue analysis was used, which is based on solid phase extraction with hydrophilic-lipophilic balance cartridges, and determination by gas chromatography-mass spectrometry. The removal efficiencies demonstrated that the treatment plant could eliminate less than 50 % of dihydrojasmonate, diclofenac and galaxolide existing in wastewater; concentration of aspirin, naproxen and tonalide could only be reduced in 15 %; and caffeine, ibuprofen and ketoprofen were not removed. Results provided basic information to decide over the necessity of complementary treatments for effluents from systems with the mentioned units. Keywords:Medicines, personal care, emerging pollutants, socio-demographic characteristics, domestic wastewater. RESUMENEn muchos países del mundo, los productos farmacéuticos y de cuidado personal (PPCPs) están presentes en el medio acuático, aumentando las preocupaciones entre la comunidad científica respecto a sus posibles destinos y efectos ambientales. Esta investigación presenta un monitoreo preliminar del uso y consumo de PPCPs y su presencia en las aguas residuales de una planta de tratamiento en zona rural de Pereira (Colombia), donde los vertimientos domésticos son tratadas en un sistema tanque séptico-filtro anaerobio y cuyo efluente se vierte en el río Otún antes de la bocatoma del acueducto de la ciudad. Los compuestos monitoreados en esta investigación incluyen ibuprofeno, naproxeno, diclofenaco, aspirina, ketoprofeno, cafeína, galaxolide, tonalida y dihidrojasmonato. Se utilizó un método de análisis multiresiduo adaptado, que se basa en la extracción en fase sólida con cartuchos de balance hydrophiliclipophilic y determinación por cromatografía de gases-espectrometría de masas. La planta de tratamiento pudo eliminar menos del 50 % del dihidrojasmonato, diclofenaco y galaxolida del agua residual; las concentraciones de aspirina, naproxeno y tonalida sólo fueron reducidas en un 15 %, y la cafeína, ibuporfeno y ketoprofeno no fueron removidos. Estos resultados proporcionan información base para decidir sob...

Various factors influence the isomeric composition of hexachlorocyclohexanes which are released to the environment. Original compositions in technical mixtures may vary slightly, but higher shifts are observable for transfer processes, bioaccumulation and microbial transformation. Consequently, the isomeric composition in environmental samples is a superposition of these processes. In this study, isomeric distributions and concentrations of hexachlorocyclohexanes were analyzed in water, sediment, and soil samples of a riverine system known to be highly contaminated by hexachlorocyclohexanes. To assess desorption of hexachlorocyclohexanes from particulate matter to water, batch shaking and percolation experiments were conducted complementary. Analyzed samples exhibited total hexachlorocyclohexane concentrations of up to 2.8 lg/g in sediments and up to 21 lg/L in river water predominated by the a-isomer. Downstream hexachlorocyclohexane pattern changed toward d-isomer domination, while overall hexachlorocyclohexane concentrations decreased. Desorption experiments supported the assumption of discrimination by preferred association of the a-and b-isomers with particulate matter, showing elevated mobilization of c-, d-and ehexachlorocyclohexanes and lower mobilization of the aand b-isomers. Soil samples of a riparian wetland exhibited elevated concentrations of hexachlorocyclohexanes exceeding 200 lg/g and predominance of a-hexachlorocyclohexanes in the top soil layer. Subjacent soil layers showed rapidly decreasing hexachlorocyclohexane concentrations and an isomeric shift toward the b-isomer. The assumed preferential mobilization of b-hexachlorocyclohexane was supported by desorption experiments. This study demonstrated firstly that transfer processes influence substantially hexachlorocyclohexane isomer distribution in the aquatic environment. Secondly, conditions of aging determine strength of association and remobilization potential of hexachlorocyclohexane residue down to an isomer-specific level.

“…After human consumption, caffeine enters wastewater treatment systems, [1][2][3][4] and have been detected in many surface water sample. [5][6][7] Furthermore, caffeine generates demethylated products because of biodegradation by human metabolism and microbial biodegradation. 8,9 Biodegradation has so far been the main process involved in the removal of caffeine during activated sludge treatment, 10 and demethylation is expected to be the main pathway.…”

For caffeine and its seven major metabolites (i.e., theobromine, theophylline, paraxanthine, 1-methylxanthine, 3-methylxanthine, 7-methylxanthine, and xanthine), an optimized analytical method using liquid chromatography-tandem mass spectrometry (LC-MS/MS) for their detection in wastewater samples was developed in this study. Extraction of these compounds (recoveries ranged from 60.3 to 83.2%) was made possible by combining universal polymeric reversedphase cartridge and polymeric strong cation exchange cartridge. This method was applied to the determination of caffeine and its metabolites in the influent and effluent of an anaerobic-anoxic-oxic (A2O) process. In the A2O influent, caffeine and its metabolites (except xanthine) ranged from 1.39 to 5.45 μg/L, and their concentrations in the A2O effluent ranged from 10.2 to 171.3 ng/L. The mass load of caffeine was 14.9 g/day/1000 inhabitants, considering the population served by the target wastewater treatment plant (WWTP). The concentration of caffeine derivatives in wastewater influent is a tool for estimating the population size in the area served by WWTPs.
