    Air pollution: Tyre and brake fatigue compound an exhausting problem

    Anyone else feeling exhausted by all this drum humming about air pollution? Indeed it appears the fumes won’t be dissipating any time soon as we consider the extent to which tyre and brake rubbish exacerbate the problem.

    Test No. 455: Performance-Based Test Guideline for Stably Transfected Transactivation In Vitro Assays to Detect Estrogen Receptor Agonists and Antagonists

    This Performance-Based Test Guideline (PBTG) describes in vitro assays, which provide the methodology of Stably Transfected Transactivation to detect Estrogen Receptor Agonists and Antagonists (ER TA assays). It comprises mechanistically and functionally similar test methods for the identification of estrogen receptor agonists and antagonists and should facilitate the development of new similar or modified test methods. The two reference test methods that provide the basis for this PBTG are: the Stably Transfected TA (STTA) assay using the (h) ERα-HeLa-9903 cell line, derived from a human cervical tumor, and the BG1Luc ER TA assay using the BG1Luc-4E2 cell line, derived from a human ovarian adenocarcinoma. The cell lines used in these assays express ER and have been stably transfected with an ER responsive luciferase reporter gene. The assays are used to identify chemicals that activate (i.e. act as agonists) and also suppress (i.e. act as antagonists) ER- dependent transcription. ER are activated following ligand binding, after which the receptor-ligand complex binds to specific DNA response elements and transactivates the reporter gene, resulting in increased cellular expression of a marker enzyme (e.g. luciferase in luciferase based systems). The enzyme then transforms the substrate to a bioluminescent product that can be quantitatively measured with a luminometer. These test methods are being proposed for screening and prioritisation purposes, but also provide mechanistic information that can be used in a weight of evidence approach.

    Putting water security at the heart of sustainable development

    Today, the challenge of water security is global and it is growing. We estimate that by 2050, over 40% of the global population will live under severe water stress; and as global population increases, so will tensions among different water uses.

    Environmental Zoning and Urban Development: Natural Regional Parks in France - Environment Working Paper

    This study provides an empirical analysis of the effects of environmental zoning on urban development. It focuses on the case of Natural Regional Parks (NRPs) in France. Of the environmental zoning instruments used in France, NRPs extend over the widest physical area. Three potential side-effects of NRPs on urban development in the regulated area are investigated.
