Veröffentlichung A walk in the PARC: developing and implementing 21st century chemical risk assessment in Europe(2023) Marx-Stoelting, Philip; Bandow, Nicole; Rivière, G.; Kolossa-Gehring, Marike; Luijten, MirjamCurrent approaches for the assessment of environmental and human health risks due to exposure to chemical substances have served their purpose reasonably well. Nevertheless, the systems in place for different uses of chemicals are faced with various challenges, ranging from a growing number of chemicals to changes in the types of chemicals and materials produced. This has triggered global awareness of the need for a paradigm shift, which in turn has led to the publication of new concepts for chemical risk assessment and explorations of how to translate these concepts into pragmatic approaches. As a result, next-generation risk assessment (NGRA) is generally seen as the way forward. However, incorporating new scientific insights and innovative approaches into hazard and exposure assessments in such a way that regulatory needs are adequately met has appeared to be challenging. The European Partnership for the Assessment of Risks from Chemicals (PARC) has been designed to address various challenges associated with innovating chemical risk assessment. Its overall goal is to consolidate and strengthen the European research and innovation capacity for chemical risk assessment to protect human health and the environment. With around 200 participating organisations from all over Europe, including three European agencies, and a total budget of over 400 million euro, PARC is one of the largest projects of its kind. It has a duration of seven years and is coordinated by ANSES, the French Agency for Food, Environmental and Occupational Health & Safety. © The Author(s) 2023Veröffentlichung 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
