This Test Guideline describes an assay that assesses early life-stage effects and potential adverse consequences of putative endocrine disrupting chemicals (e.g. oestrogens, androgens and steroidogenesis inhibitors) on fish sexual development. In the test, fish are exposed, from newly fertilized...

This Test Guideline is designed to assess the toxicity of substances to freshwater aquatic plants of the genus Lemna (duckweed). Exponentially growing plant cultures of the genus Lemna (Lemna gibba and Lemna minor usually) are allowed to grow as monocultures in, at least, five concentrations of...

This manual provides guidance on how to measure and interpret measurements of globalisation's extent and intensity. The manual defines concepts and puts forward guidelines for data collection and fine-tuning of globalisation indicators. In particular, it looks at indicators related to foreign...

The fish are exposed to the test substance preferably for a period of 96 hours. Mortalities are recorded at 24, 48, 72 and 96 hours and the concentrations which kill 50 per cent of the fish (LC50) are determined where possible. One or more species may be used, the choice being at the discretion...

This Test Guideline has been designed to obtain the information necessary to confirm or to further characterise the potential neurotoxicity of chemicals in adult animals. This Test Guideline is designed for use with the rat. It specifically addresses the daily oral administration, by gavage, (in...
