A non-invasive observation parameter to complement sediment bioassays using Myriophyllum aquaticum

Autor: René Schreiber, Ute Feiler, Anette Küster, Rolf Altenburger, Matthias Grote

Publikováno v: Journal of Soils and Sediments. 11:1419-1431

Purpose The objective of this study was to modify a sediment contact protocol to a multiwell plate exposure system which supplements measurement of the fresh weight change (FWC) using the non-invasive effective quantum yield of energy conversion at p

A novel in vitro system for the determination of bioconcentration factors and the internal dose in zebrafish (Danio rerio) eggs

Autor: Albrecht Paschke, Gerrit Schüürmann, René Schreiber, Eberhard Küster, Rolf Altenburger

Publikováno v: Chemosphere. 77:928-933

In this study a novel in vitro approach for the determination of bioconcentration factors (BCF) and rate constants of lipophilic substances utilizing zebrafish (Danio rerio) eggs is presented. Zebrafish eggs were exposed in a static exposure regime t

Metabolic Effect Level Index Links Multivariate Metabolic Fingerprints to Ecotoxicological Effect Assessment

Autor: René Schreiber, Hermann Heilmeier, Mechthild Schmitt-Jansen, Janet Riedl, Rolf Altenburger, Matthias Otto

Publikováno v: Environmental sciencetechnology. 49(13)

A major goal of ecotoxicology is the prediction of adverse outcomes for populations from sensitive and early physiological responses. A snapshot of the physiological state of an organism can be provided by metabolic fingerprints. However, to inform c

Dynamics of organochlorine contaminants in surface water and in Myriophyllum aquaticum plants of the river Xanaes in central Argentina during the annual dry season

Autor: Carlos A. Harguinteguy, Martin Diego Manetti, René Schreiber

The dynamics of organochlorine pesticides (OCPs) and their major metabolites were studied in surface waters and plants of the River Xanaes (province of Córdoba, Argentina) during the annual dry season. The results of the 5-month monitoring study (Ap
