More than 25% of the adult European population suffers from contact allergy, with fragrance substances recognized as one main causes. Since 2005, 26 allergens have been mandatory to label in cosmetic products within EU if present at 10 ppm or above leave-on and 100 wash-off cosmetics.To examine exposure, based on ingredient labelling, fragrances a sample 5588 fragranced products.The investigated were identified through novel, non-profit smartphone application (app), designed provide...
SWINGS was a cooperation project between the European Union and India, aiming at implementing state of art low-cost technologies for treatment reuse domestic wastewater in rural areas India. The largest plant consists high-rate anaerobic system, followed by vertical horizontal subsurface flow constructed wetlands with area around 1,900 m2 final step consisting solar-driven anodic oxidation (AO) ultraviolet (UV) disinfection units allowing direct treated water. implementation operation two...

A prototype microfluidic immunosensor for detecting 2,6-dichlorobenzamide showing potential at-line monitoring of ground water.
Fragrances are among the most common contact allergens in children. Cosmetic products frequent source of skin exposure.To investigate exposure to fragrance Danish children, based on a sample 1179 cosmetic marketed for children.Information regarding children was obtained using non-profit smartphone application registry, with data from December 2015 November 2022.The number validated 26 537, which 1349 After elimination duplicates, (4.4%) individual remained. The majority 53.8% (634/1179) were...
ABSTRACT Herbicides may leach from agricultural fields into ground water feeding adjacent wetlands. However, only little is known of the fate herbicides in wetland areas. The purpose study was to examine potential a riparian fen mineralize that could an catchment area. Slurries were prepared sediment and collected different parts representing redox conditions. slurries amended with O 2 , NO − 3 SO 2− 4 CO or alone as electron acceptors simulate situ conditions their ability mecoprop,...
This study has documented that a considerable degradation potential related to aromatic hydrocarbons and nitrogen-, sulphur- oxygen- containing compounds is associated with the free-living ground water bacteria. All studies were performed under aerobic conditions surplus of nitrogen phosphorus. After lag period, which differs considerably between locations upstream downstream hydrocarbon spills, bacteria are able degrade concentrations less than 1 µg/l. The from one site naphthalene...
A mixed culture of nitrate-reducing bacteria degraded o-cresol in the presence toulene as a primary growth substrate. No degradation was observed absence toluene or when grew on p-cresol and 2,4-dimethylphenol. In batch cultures, started after to below 0.5 1.0 mg/liter but continued only for about 3 5 days depletion since had limited capacity once depleted. The total amount proportional metabolized, with an average yield 0.47 mg per metabolized. Experiments [ring-U-14C]o-cresol indicated...
Analysis of the 1960–76 creel survey data for Lake Nipissing and relevant collected by Fisheries Assessment Unit from 1969 to 1976 showed a generally declining walleye (Stizostedion vitreum vitreum) contribution fishery. Variable year-class strengths alone did not adequately account changes. Overexploitation resource was strongly suggested decreased catches per unit effort, recruitment younger (many which probably never spawned) into fishery at least after 1968, increased growth rate. The...
Abstract This study investigated the ability of a microbial community to degrade linear alkylbenzene sulfonate (LAS) in soil columns under water‐saturated conditions. The mineralization LAS was further studied batch experiment using pre‐exposed and unexposed as well from inlet outlet columns. (4 mg/L) added continuously Three pulses 14 C‐labeled ( C‐dodecyl‐[ 6 ]‐benzene sulfonate) were at intervals 2 weeks, measured production CO . primary degradation close 100% columns, whereas compound...
Abstract Urban cloudburst management may include the intentional temporary storage of flood water in green recreational areas. In cities with combined sewers, this will expose population visiting area to sewage and increase risk diarrhoeal disease. We present a unique approach estimate disease after urban flooding. The exposure scenario was: rainwater mixed flows into park; pathogens deposit on grass; discharge, baby plays grass is exposed deposited by hand-to-mouth transfer. work included...
