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...

Containing sprawl is a major preoccupation of many urban planners, who view sprawl as responsible for driving up environmental costs and congestion. Nevertheless, many economists see benefits to sprawl, allowing households access to larger and cheaper properties. This Round Table examines the...

This Round Table is one of a series of research events to discuss tools to improve transport planning. It addressed the macroeconomic effects of transport infrastructure policies, and aimed at identifying analytical and empirical tools that could determine the overall volume of public...

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 Test Guideline describes a method which is an adaptation of the Soap and Detergent Association semi-continuous activated sludge (SCAS) procedure for assessing the primary biodegradation of alkyl benzene sulphonate. The test does not simulate those conditions experienced in a sewage...

Much of the current policy debate has considered infrastructure charges as a form of “fiscal” instrument for managing transport demand. The Round Table analysed the opportunities for setting infrastructure service prices so that they also provide guidance for the supply of services. It...

This test guideline describes a test procedure to gain information on dispersion stability of manufactured nanomaterials in simulated environmental media. The main purpose of this guideline is to assess the ability of a nanomaterial to attain a colloidal dispersion and to conserve this...

This Test Guideline describes the Medaka Extended One Generation Test (MEOGRT), which exposes fish over multiple generations to give data relevant to ecological hazard and risk assessment of chemicals, including suspected endocrine disrupting chemicals (EDCs). Exposure in the MEOGRT starts with...

The purpose of the test is to measure the capacity of a chemical to activate or inhibit the transcription of a genetic construct (THb/ZIP-GFP X. laevis eleutheroembryos) either by binding to the thyroid hormone receptor or by modifying the amount of thyroid hormone available for transcription....
