Veröffentlichung Deutsche Umweltstudie zur Gesundheit von Kindern und Jugendlichen 2014-2017 (GerES V)(Umweltbundesamt, 2023) Hahn, Domenica; Kolossa-Gehring, Marike; Lange, Rosa; Lemke, Nora; Murawski, Aline; Peisker, Jasmin; Debiak, Malgorzata; Rucic, Enrico; Zimmermann, Philipp; David, Madlen; Gerofke, Antje; Weber, Till; Pack, Kim LauraIn der Deutschen Umweltstudie zur Gesundheit (GerES) wird die Schadstoff-Belastung der Bevölkerung repräsentativ für die Menschen in Deutschland erhoben. In der fünften Erhebung, GerESV (2014-2017), wurden 2.294 Kinder und Jugendliche im Alter von 3 bis 17 Jahren aus 167 Orten in ganz Deutschland untersucht. GerES V ist eine bevölkerungsrepräsentative Querschnittstudie und wurde in enger Kooperation mit der "Studie zur Gesundheit von Kindern und Jugendlichen in Deutschland" (KiGGS Welle 2) des Robert-Koch-Instituts durchgeführt. Im Human-Biomonitoring (HBM) von GerESV wurden 107 verschiedene Substanzen im Blut bzw. Urin der Teilnehmenden gemessen. Der vorliegende Bericht fasst die HBM-Ergebnisse von GerESV zusammen. Bei Vorliegen entsprechender Beurteilungswerte wird eine gesundheitliche Bewertung vorgenommen. Der Bericht gibt einen Überblick über die Abläufe der Datenerhebung und die chemisch-analytischen und statistischen Methoden. Die wichtigsten Ergebnisse zu Belastungsquellen und -pfaden sowie besonders belasteten Bevölkerungsgruppen sind zusammengefasst und in aggregierter Form tabellarisch präsentiert. Für jede untersuchte Substanz werden außerdem die Quellen, die toxikologischen Eigenschaften und aktuellen Regulationen aufgeführt. Die bisherige Nutzung der Daten aus GerES V für Politik- und Öffentlichkeitsarbeit sowie in internationalen Kooperationen ist ebenfalls dargelegt.

While more and more national programs in Europe have started monitoring internal exposure to phthalates and its substitute 1,2-Cyclohexanedicarboxylic acid (DINCH), the comparability of results from such existing human biomonitoring (HBM) studies across Europe is challenging. They differ widely in time periods, study samples, degree of geographical coverage, design, analytical methodology, biomarker selection, and analytical quality assurance level. The HBM4EU initiative has gathered existing HBM data of 29 studies from participating countries, covering all European regions and Israel. The data were prepared and aggregated by a harmonized procedure with the aim to describe - as comparably as possible - the EU-wide general population's internal exposure to phthalates from the years 2005 to 2019. Most data were available from Northern (up to 6 studies and up to 13 time points), Western (11; 19), and Eastern Europe (9; 12), e.g., allowing for the investigation of time patterns. While the bandwidth of exposure was generally similar, we still observed regional differences for Butyl benzyl phthalate (BBzP), Di(2-ethylhexyl) phthalate (DEHP), Di-isononyl phthalate (DiNP), and Di-isobutyl phthalate (DiBP) with pronounced decreases over time in Northern and Western Europe, and to a lesser degree in Eastern Europe. Differences between age groups were visible for Di-n-butyl phthalate (DnBP), where children (3 to 5-year olds and 6 to 11-year olds) had lower urinary concentrations than adolescents (12 to 19-year-olds), who in turn had lower urinary concentrations than adults (20 to 39-year-olds). This study is a step towards making internal exposures to phthalates comparable across countries, although standardized data were not available, targeting European data sets harmonized with respect to data formatting and calculation of aggregated data (such as developed within HBM4EU), and highlights further suggestions for improved harmonization in future studies. © 2023 by the authorsVeröffentlichung Glyphosate and aminomethylphosphonic acid (AMPA) in urine of children and adolescents in Germany - Human biomonitoring results of the German Environmental Survey 2014-2017 (GerES V)(2021) Conrad, André; Kolossa-Gehring, Marike; Lemke, Nora; Murawski, Aline; Schmied-Tobies, Maria Irene HildeSince the 1970s, glyphosate has become the most used herbicide of the world. The general population is ubiquitously exposed to glyphosate. Its long-term toxicity, carcinogenic potential and other health effects are controversially discussed. Even though the possible health impacts of glyphosate are of global concern, no population-wide monitoring of glyphosate was done yet. This study presents the worldwide first population-representative data on glyphosate and its metabolite aminomethylphosphonic acid (AMPA) for children and adolescents. 2144 first-morning void urine samples of 3-17-year-old children and adolescents living in Germany were analysed for concentrations of glyphosate and AMPA in the German Environmental Survey for Children and Adolescents 2014-2017 (GerES V). In 52 % of the samples (46 % for AMPA) the urinary glyphosate concentrations were above the limit of quantification of 0.1 (microgramm)/L. The geometric mean concentrations were 0.107 (microgramm)/L (0.090 (microgramm)/gcreatinine) for glyphosate and 0.100 (microgramm)/L (0.085 (microgramm)/gcreatinine) for AMPA. No clear association between exposure to glyphosate or AMPA and vegetarian diet or consumption of cereals, pulses, or vegetables could be identified. The low quantification rate and the 95th percentiles for glyphosate and AMPA of around 0.5 (microgramm)/L demonstrate an overall low exposure of the young population in Germany.

A biomonitoring method to evaluate exposure to these compounds was developed using N-methylmalonamic acid (NMMA), the main metabolite of both, methylisothiazolinone and methylchloroisothiazolinone, as the exposure biomarker. First-morning void urine samples (N = 2078) of 3- to 17-year-old children and adolescents living in Germany were analysed for concentrations of NMMA in the population representative German Environmental Survey for Children and Adolescents GerES V (2014-2017). NMMA was quantified in almost all samples, with a geometric mean concentration of 6.245 My g/L (5.303 my g/gcrea) and a 95th percentile of 15.0 my g/L (12.6 ÎÌg/gcrea). Urinary concentrations could not be related to self-reported application of specific cleaning agents or personal care products, leaving potential, specific sources of exposure unrevealed as most products relevant for isothiazolinone exposure are used ubiquitously. For the first time, reference values can be derived for urinary NMMA for children and adolescents in Germany, facilitating a more substantiated exposure assessment. © 2020 Published by Elsevier GmbH.Veröffentlichung Polychlorinated biphenyls (PCB) and organochlorine pesticides (OCP) in blood plasma - results of the German environmental survey for children and adolescents 2014-2017 (GerES V)(2020) Bandow, Nicole; Conrad, André; Kolossa-Gehring, Marike; Murawski, Aline; Sawal, GeorgeThe German Environmental Survey for Children and Adolescents 2014-2017 (GerES V) investigated the current internal exposure to polychlorinated biphenyls (PCB) and organochlorine pesticides (OCP). These analyses were carried out for a population-representative sub-sample of 1135 children and adolescents (aged 3-17 years) of all 2394 GerES V participants. Blood plasma samples were analyzed for seven indicator PCB (PCB 28, PCB 52, PCB 101, PCB 118, PCB 138, PCB 153 and PCB 180) and selected OCP (hexachlorobenzene, three hexachlorocyclohexane isomers, 4,4'-DDT, 4,4'-DDD and 4,4'-DDE). Despite risk mitigation measures and bans put into force some decades ago children and adolescents living in Germany are still exposed to PCB and OCP: Highest geometric mean plasma concentrations were measured for 4,4'-DDE (0.158 g/L), followed by PCB 138 (0.049 g/L), PCB 153 (0.066 g/L) and PCB 180 (0.032 g/L). Different application patterns of compounds between former East and former West Germany are still reflected by differences in plasma concentrations. Significant differences between age groups and by sexes were found. Moreover, the influence of breastfeeding and fish consumption, which was also found in other studies, was confirmed. Comparison with the results of GerES 2003-2006 confirms a decreasing trend in blood samples observed world-wide. Currently, health-based guidance values for PCB are still exceeded, though to a very limited extent. Also, the widespread occurrence of these compounds underlines the need for further monitoring of these compounds in humans although they are no longer marketed. Quelle: https://www.sciencedirect.com
