Darstellung der in den NRW-Standard-Stammdaten (NRW-Standards) geführten Stoffe und deren Verschlüsselung. NRW-Standards sind die Stammdaten eines Parameters zur Analyse der Umweltmedien Wasser, Abwasser, Boden, Luft, Abfall und auch industriell hergestellter Material (z.B. Düngemittel). Die Stammdaten setzen sich zusammen aus den Informationen: [1] Prüfmerkmal (auch Stoff genannt), [2] Analyse-Norm und andere Vorschriften, [3] Einheit (z.B. mg/l)
Each issue of the German Environment Agency's "What Matters" magazine is devoted to relevant topics in the field of environmental protection. It is published every six months. In its 1-2020 issue, UBA looks at chemicals with the abbreviation PFAS : per- and polyfluorinated alkyl substances. These chemicals are used in many applications for their water, grease and soil-repellent function. Coffee-to-go cups, for example, can be coated with PFAS, just like water-repellent outdoor textiles. These chemicals are also contained in fire-fighting foams. There are a total of 4,700 different substances, the effects of which on humans and the environment are largely unresearched. PFAS are very durable and mobile. They are distributed across the globe by wind and water and accumulate in water, soil and living organisms - including humans. The What Matters magazine looks at these questions: What exactly are PFAS? How are they used? How do they get into the environment? And what can be done about the substances?

Useful or harmful? A substance with many facets The element nitrogen is essential for all life on earth. In order to act as a building block of life however, it must form chemical compounds with other elements and thus be converted into its reactive state. Despite being the principle component of our atmosphere, molecular atmospheric nitrogen cannot be used directly by most living organisms. How the modern circular economy works The growing level of global consumption requires us to rethink how we deal with natural resources. A circular economy – one which fully integrates all aspects ranging from product design, sustainable production methods and patterns of consumption to recycling – makes significant contributions to resource conservation. The (energy) transition in the transport sector The transport sector, especially road transport, is responsible for around 18 percent of German greenhouse gases – and is, unfortunately, the only area that has not been able to reduce its emissions since 1990. To change this situation, a large part of the traffic must be avoided in the first place and low-emission modes must become more widely implemented. In addition, we need a significantly more climate-friendly energy supply for the traffic. Veröffentlicht in Broschüren.
This paper relates to the assessment of transformation products (i.e. metabolites, degradation or reaction products), which are formed from plant protection products. It addresses a detail in Regulation (EC) No. 1107/2009 which is not in line with other substance regulations for REACH , medicinal products, and biocides. Our concern: Also transformation products can be hazardous substances. Meanwhile, they are not yet covered within the POP / PBT /vPvB assessment and the approval criteria for active substances. Our proposal: At least transformation products occurring in a relevant amount should be included in the assessment and the approval criteria in the same way as active substances.

This evaluation of air quality in Germany in the year 2018 is based on preliminary data which has not yet been conclusively audited from the air monitoring networks of the federal states and the UBA , valid on 18rd January 2019. Due to the comprehensive quality assurance within the monitoring networks, the final data will only be available in mid-2019. The currently available data allows for a general assessment of the past year. The following pollutants were subject to consideration: particulate matter ( PM10 and PM2.5), nitrogen dioxide (NO2) and ozone (O3), since, the limit and target values for the protection of human health are still exceeded for such substances.

This evaluation of air quality in Germany in the year 2017 is based on preliminary data which has not yet been conclusively audited from the air monitoring networks of the federal states and the UBA , valid on 23rd January 2018. Due to the comprehensive quality assurance within the monitoring networks, the final data will only be available in mid-2018. The currently available data allows for a general assessment of the past year. The following pollutants were subject to consideration: particulate matter ( PM10 and PM2.5), nitrogen dioxide (NO2) and ozone (O3), since, the limit and target values for the protection of human health are still exceeded for such substances.

This evaluation of air quality in Germany in the year 2019 is based on preliminary data which has not yet been conclusively audited from the air monitoring networks of the federal states and the German Environment Agency (Umweltbundesamt), valid on January 2020. Due to the comprehensive quality assurance within the monitoring networks, the final data will only be available in mid-2020. The currently available data allows for a general assessment of the past year. The following pollutants were subject to consideration: particulate matter ( PM10 and PM2.5), nitrogen dioxide (NO2) and ozone (O3), since, the limit and target values/ WHO recommendations for the protection of human health are still exceeded for such substances.

In this project, the guidance documents should be verified using the example of potentially endocrine disrupting (ED) chemicals. Three substances were selected mainly based on in silico (2,4,6-tribromophenol), in vitro (benzanthrone) and in vivo data (benzophenone-2). In order to evaluate the potential for endocrine disruption, several additional in vitro tests and one in vivo test were performed for two of the selected substances. For all three selected substances, an integrated assessment of potential endocrine activity in aquatic vertebrates was performed. Results of this assessment are presented in a non-public annex to this report. Veröffentlicht in Texte | 48/2014.
Protection of drinking water resources from PMT/vPvM substances: Revised guidance for REACH registrants on the identification of these substances of very high concern (SVHC). Only 1.9 % of the unique chemical structures in the REACH registration database fall in the new CLP hazard classes PMT and vPvM. However, for a total of 64 % no final assessment was achieved, either due to lack of test data (41 %) or due to ambiguous assessment (23 %). These guidance and methods can be used immediately by REACH registrants to ensure the safety of their substances, to close data gaps and, if necessary, to use safer alternatives, or to implement risk mitigation measures (RMMs).
