Grundwasser · 2026 · Springer
Zusammenfassung Die Studie untersucht die Entwicklung der Grundwasserstände in Deutschland anhand von 5844 Messstellen sowie deren Reaktionsdynamik gegenüber klimatologischen Antrieben im Referenzzeitraum 1991–2020. Zusätzlich wird die Entwicklung seit 2018 im Kontext der außergewöhnlichen Dürreperiode betrachtet, um die Reaktionsfähigkeit und Vulnerabilität der Grundwassersysteme gegenüber extremen klimatischen Bedingungen zu...

The Working Group on Method Performance Requirements (WG-MPR) of the European Network of GMO Laboratories (ENGL) and the EU Reference Laboratory for Genetically Modified Food and Feed (EURL GMFF) have extended the scope of its guidance document on the “Definition of minimum performance requirements for analytical methods of GMO testing”. This document establishes criteria for the development and validation of methods for GMO a...

The detection of genetically modified organisms (GMO) is crucial for regulatory compliance and market control. Therefore, detection methods are constantly being developed and improved. New genomic techniques (NGT) present unique challenges for detection due to the minimal genetic changes they introduce. The ‘International Conference on GMO Analysis and New Genomic Techniques’ held in March 2023 in Berlin, explored advances in...

The international working group “Development of methods for identification of foodstuffs produced by means of genetic engineering techniques” was established pursuant to § 64 of the German Food and Feed Code (LFGB). It has developed a guideline for implementing and verifying digital PCR methods previously validated as real-time PCR techniques. While event-specific methods in testing of genetically modified organisms (GMO) have...

The diversity of genetically modified plants used for food and feed is increasing worldwide. For the detection and control of these products, efficient and reliable analytical tools are a prerequisite. This can be done by screening for specific DNA-elements and constructs characteristic of transgenic plants. In the past, numerous methods have already been published. However, several genetically modified plants are not covered...
