Von Juni 2018 bis Mai 2019 wurde die Außenluft und die Deposition an den UBA-Messstationen Waldhof und Schmücke auf polychlorierte Dibenzodioxine und -furane (PCDD/F) und polychlorierte Biphenyle (PCB) untersucht, um aktuelle Werte für die Hintergrundbelastung in Deutschland zu ermitteln.

This guidance describes methods and criteria to evaluate rodent break back/snap traps regarding their animal welfare impact and efficacy. The assessment follows a tiered approach starting with the tests of the mechanical properties, followed by a semi-field trial testing the animal welfare impact and basic efficacy, and optionally supplemented by the extended efficacy test in the field.

Climate-impacting refrigerants and blowing agents are often replaced by halogenated substances which, despite their low global warming potential, are not unproblematic for the environment. The study examines quantities used and emissions today and in the future as well as degradation pathways and products.

Phosphonate sind schwer abbaubare Komplexbildner, welche über das Abwasser in die Gewässer eingetragen werden. Im Rahmen eines Vorhabens zu schwer abbaubaren Verbindungen in Wasch- und Reinigungsmitteln (FKZ 3709 65 430) wurde festgestellt, dass der überwiegende Teil der im Abwasser enthaltenen Phosphonate aus dem Einsatz in Wasch- und Reinigungsmitteln stammt.

The restriction process is a central instrument of REACH to regulate risks of substances by means of a restriction or prohibition for certain concentration ranges and uses. This project analysed the current implementation of the process based on a literature review and case studies with a focus on the workload for authorities, the duration of the procedure and the role oft he committees.

The authorisation process is a central instrument of REACH, aiming at reducing risks from the use of Substances of Very High Concern (SVHC). The goal is a stepwise elimination of such substances from the market with the option to grant temporary exemptions.

This report is a review of the existing literature which determine the current level of knowledge of the benefits and costs associated with REACH. The main focus of the review was on the identification of the gaps in the assessment of benefits.

Enhancing substitution of substances of concern with less hazardous alternatives will remain a key challenge for chemicals management in the coming years and is a central aim of REACH.

The project “PBT - Quo vadis?” includes an examination of the concept currently valid under REACH for evaluating the PBT properties of chemicals from a scientific and regulatory point of view. A main focus of the examination was on chemicals which, despite their worrying properties, have not yet been covered by the PBT concept.

The report describes the scientific background and motivation to develop an OECD Guidance Document on the determination on dissolution and dispersion stability of nanomaterials in the environment. It presents the process and approach to develop the GD and summarizes its relevance for risk assessment and regulation of nanomaterials. The “OECD Guidance Document No.

The subject of this project was the preparation of substance reports for five substances relevant for building products emissions. For these substances, the toxicological data basis were researched, compiled and evaluated, and EU-LCI values were proposed. The EU-LCI values allow the harmonisation of the health assessment of building products emissions throughout Europe.

Nanomaterials can have different or new properties in comparison with conventional chemicals and materials. Meanwhile the substance legislations was partially adapted by nano-specific provisions; for parts however adaptation needs still exist. As a result, specific environmental risks cannot be fully described and assessed as well as appropriate measures to minimize the risks cannot be taken.
