Content: 

An interdisciplinary research team around Marko Freese and Larissa Rizzo in collaboration with Henner Hollert & Markus Brinkmann from the Department of Ecosystem Analysis and scientists from different environmental and medical departments of RWTH Aachen University charts on the analysis of bone resorption and body reorganizaton during maturation in European eel (Anguilla anguilla). 

The authors used hormone treated eels to found that the eels' average bone mass and mineral content of anguilled eels declined with the onset of silvering. Moreover, the proportion of phosphorus and calcium in soft tissues measured with energy-dispersive X-ray spectroscopy increased as maturation progressed and showed that eels use their bones and muscles as energy and mineral stores to build up gonads during maturation. 

Formally unreported aspects of anthropogenic impact could be identified by illustration the metabolic fluxes and fate of mobilized minerals and metals. 

According to the authors, the results show an important aspect in the dramatic body reorganization during reproduction of the European eel. The eel has the potential to be an interesting model organism for the analysis of physiological pathways connecting lipid metabolism and mineral retention.

Shao et al (2019): "Toxicity of 10 organic micropollutants and their mixture: Implications for aquatic risk assessment" Water Research 153:357-368

Content: Ten organic micropollutants were analysed using literature data, laboratory experiments and prediction techniques. All 10 micropollutants were capable of causing toxicity in zebrafish embryos, aquatic invertebrates and algae. Triclosan, carbamazepine, diazinon and diuron were the most hazardous compounds in the Danube River and the Rhine River. The artificial mixture concurred with an independent action (IA) model, and risk quotients were extrapolated. The micropollutant mixture may pose a potential risk at the environmentally measured concentrations.
