*EMERGING contaminants
Abstract

This article discusses the identification of emerging contaminants in the Estonian aquatic environment. The study collected data from 2016 to 2023 through various projects, including Estonian national environmental monitoring. The screening methods used identified both new substances and substances that were already regulated and considered a risk factor. The presence of these substances varied in different regions, and some substances had significant effects only in Estonian waters. The study emphasizes the importance of ongoing monitoring and the use of the latest analytical methods to prevent long-term environmental problems. [Extracted from the article]

Abstract

According to the Article 17(2) of the Marine Strategy Framework Directive (MSFD), Member States have to review and update their marine strategies every six years. This requires updates of the MSFD Articles 8, 9 and 10 by 2018. The current report provides an overview of the substances, matrices and threshold values that Member States intend to use for the assessment of the Descriptor 8 in this MSFD reporting cycle. This compilation aims at evaluating gaps and discrepancies between Member States and identifying aspects that need further harmonization. It also helps understand which issues should be addressed to achieve consistency with the new MSFD Commission Decision (EU 2017/848). The information has been gathered from the contributions of the MSFD Expert Network on Contaminants, an informal network established to support MSFD implementation. This work is part of a process to help regulators to assess relevant contaminants in their jurisdictional area, thus aiming at EU national authorities but also at Regional Sea Conventions in the shared marine basins., JRC.D.2-Water and Marine Resources

11. Plasmid with Colistin Resistance Gene mcr-1in Extended-Spectrum-β-Lactamase-Producing Escherichia coliStrains Isolated from Pig Slurry in Estonia

Abstract

ABSTRACTA plasmid carrying the colistin resistance gene mcr-1was isolated from a pig slurry sample in Estonia. The gene was present on a 33,311-bp plasmid of the IncX4 group. mcr-1is the only antibiotic resistance gene on the plasmid, with the other genes mainly coding for proteins involved in conjugative DNA transfer (taxA, taxB, taxC, trbM, and the pilXoperon). The plasmid pESTMCR was present in three phylogenetically very different Escherichia colistrains, suggesting that it has high potential for horizontal transfer.

Abstract

The World Health Organization Global Action Plan recommends integrated surveillance programs as crucial strategies for monitoring antibiotic resistance. Although several national surveillance programs are in place for clinical and veterinary settings, no such schemes exist for monitoring antibiotic-resistant bacteria in the environment. In this transnational study, we developed, validated, and tested a low-cost surveillance and easy to implement approach to evaluate antibiotic resistance in wastewater treatment plants (WWTPs) by targeting cefotaxime-resistant (CTX-R) coliforms as indicators. The rationale for this approach was: i) coliform quantification methods are internationally accepted as indicators of fecal contamination in recreational waters and are therefore routinely applied in analytical labs; ii) CTX-R coliforms are clinically relevant, associated with extended-spectrum ��-lactamases (ESBLs), and are rare in pristine environments. We analyzed 57 WWTPs in 22 countries across Europe, Asia, Africa, Australia, and North America. CTX-R coliforms were ubiquitous in raw sewage and their relative abundance varied significantly (
