    Background: Parabens, widely used as preservatives in cosmetics, foods, and other consumer products, are suspected of contributing to allergy susceptibility. The detection of parabens in the placenta or amniotic fluid raised concerns about potential health consequences for the child. Recently, an increased asthma risk following prenatal exposure has been reported. Here, we investigated whether prenatal paraben exposure can influence the risk for atopic dermatitis (AD). Methods: 261 mother-child pairs of the German mother-child study LINA were included in this analysis. Eight paraben species were quantified in maternal urine obtained at gestational week 34. According to the parental report of physician-diagnosed AD from age 1 to 8 years, disease onset, and persistence, childhood AD was classified into four different phenotypes. Results: 4.6% (n = 12) and 12.3% (n = 32) of the children were classified as having very early-onset AD (until age two) either with or without remission, 11.9% (n = 31) as early-onset (after age two), and 3.1% (n = 8) as childhood-onset AD (after age six). Exposure to ethylparaben and n-butylparaben was associated with an increased risk to develop very early-onset AD without remission (EtP: adj.OR/95% CI:1.44/1.04-2.00,nBuP:adj.OR/95% CI:1.95/1.22-3.12). The effects of both parabens were predominant in children without a history of maternal AD and independent of children's sex. Conclusion: Prenatal EtP or nBuP exposure may increase children's susceptibility for persistent AD with disease onset at very early age. This association was particularly pronounced in children without a history of maternal AD, indicating that children without a genetic predisposition are more susceptible to paraben exposure

    Anthropogenic organic micro-pollutants and pathogens in the urban water cycle: assessment, barriers and risk communication (ASKURIS)

    In urban areas, water often flows along a partially closed water cycle in which treated municipal wastewater is discharged into surface waters which are one source of raw waters used for drinking water supply. A number of organic micro-pollutants (OMP) can be found in different water compartments. In the near future, climatic and demographic changes will probably contribute to an increase of OMP and antibiotic-resistant pathogens in aquatic ecosystems. The occurrence of OMP, possible adverse effects on aquatic organisms and human health and the public perception must be carefully assessed to properly manage and communicate potentially associated risks and to implement appropriate advanced treatment options at the optimum location within the water cycle. Therefore, the interdisciplinary research project ASKURIS focuses on identification and quantification, toxicological assessment and removal of organic micro-pollutants and antibiotic-resistant pathogens in the Berlin water cycle, life cycle-based economic and environmental assessment, public perception and management of potential risks

    Gedruckt erschienen im UniversitĂ€tsverlag der TU Berlin, ISBN 978-3-7983-2814-3Im Forschungsprojekt ASKURIS wurden das Auftreten und die Entfernung organischer Spurenstoffe und resistenter Krankheitserreger in urbanen WasserkreislĂ€ufen erforscht. Neueste analytische Methoden wurden eingesetzt, um entlang des Wasserkreislaufes bekannte Substanzen in kleinsten Konzentrationen zu quantifizieren und unbekannte Spurenstoffe zu identifizieren. Deren Entfernung durch bestehende und zusĂ€tzliche technische Barrieren (Aktivkohle und/oder Ozon) wurde an unterschiedlichen Stellen des Wasserkreislaufes untersucht. FĂŒr eine Bewertung der technischen Barrieren wurden Kosten und Auswirkungen auf die Umwelt bilanziert. Toxische Effekte auf Mensch und Umwelt wurden untersucht, um ein eventuelles Risiko abschĂ€tzen zu können. Mit empirischen, sozialwissenschaftlichen Methoden wurde die Wahrnehmung von Risiken in der Bevölkerung analysiert. Die Forschungsergebnisse aus ASKURIS wurden in das Risikomanagementsystem des grĂ¶ĂŸten deutschen Wasserver- und -entsorgers integriert.A partially closed water cycle may exist in urban areas, whereby treated municipal wastewater is discharged into surface waters used as a source for the drinking water supply.

The occurrence of OMP, possible adverse effects on aquatic organisms and human health and the public perception must be carefully assessed to properly manage and communicate potential risks and to implement advanced treatment options (activated carbon or ozone) at the optimum point within the water cycle. Therefore, the interdisciplinary research project ASKURIS focused on the identification and quantification of OMP, on the toxicological assessment and removal of organic micro-pollutants and antibiotic-resistant pathogens in the Berlin water cycle, on life-cycle based economic and environmental assessments, the public perception and management of potential risks.BMBF, 02WRS1278, RiSKWa - Verbundprojekt ASKURIS: Anthropogene Spurenstoffe und Krankheitserreger im urbanen Wasserkreislauf: Bewertung, Barrieren und Risikokommunikatio
