Veröffentlichung Contaminants in water resources: Prioritization and recommendations for conducting a “cold” biodegradation simulation test according to OECD TG 309(German Environment Agency, 2024) Nödler, Karsten; Neumann, Michael; Neumann, MichaelThe threat posed to drinking water resources by persistent and mobile substances has been recognized for decades. However, for many contaminants, some of which have been detected in drinking water resources for decades, there is still no conclusive assessment of their intrinsic biodegradability in the aquatic environment by the responsible companies. The recommendations are intended to make it easier for a wide range of users, such as water utility laboratories and government agencies with established analytical facilities, to perform a "cold" degradation test in accordance with OECD TG 309 for substances found in their own water resources.Veröffentlichung Protecting the sources of our drinking water(Umweltbundesamt, 2019) Neumann, Michael; Schliebner, Ivo; Deutschland. UmweltbundesamtChemicals with a specific combination of intrinsic substance properties pose a hazard to the sources of our drinking water, including substances that are very persistent (vP) in the environment and very mobile (vM) in the aquatic environment as well as substances that are persistent (P), mobile (M), and toxic (T). This publication presents the result of the scientific and technical development of the PMT/vPvM criteria under EU REACHRegulation (EC) No 1907/2006. The scientific and regulatory considerations include (1) monitoring data, (2) simulation and model studies and (3) impact considerations. This can be considered a ready-to-use tool for industry to identify PMT/vPvM substances. Quelle: http://www.umweltbundesamt.de/
