Regulation (EC) No 1907/2006 concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) requires that environmental exposure assessments be performed for all uses of dangerous substances that are marketed in the Europ

Based on the test results of a large number of chemical substances, the comparability of different biodegradation test methods was assessed in terms of passing or failing threshold values commonly used for the biodegradability characterisation of che

In assessing the environmental risk of a chemical it is necessary to predict safe levels in the environment, but this requires extrapolation from relatively small databases. To improve understanding of the use of existing data for such extrapolations

In contrast to the substantial quantity of information available on the ecotoxicity of chemical substances to freshwater organisms, there are relatively few data on the effects of many such substances to marine and estuarine organisms. While it is de

Die ersten Funde fossiler Ciliaten werden aus der Unter-Trias (Oberes Spathium) von Spitzbergen beschrieben. Die ehemals aus Pseudochitin bestehenden Gehause der Ciliaten sind fruhdiagnetisch in Apatit umgewandelt worden und so erhalten geblieben. Di

Products used against parasitic arthropods must be tested for their efficacy. Because the supply of parasitic organisms for such tests may be a limiting factor, it is best to conduct these tests with a model organism. We show that the cockroach is a

Summary 1. Symphorinot ciliates are divided into biological groups because of their local specifity. I have substituted the term „Korperteilspezifitat” by the more exact term “Tragertopographie” (host-topography). 2. The system of peritrich c
