Clean air in europe for all: taking stock of the proposed revision to the ambient air quality directives. A Joint ERS, HEI, and ISEE Workshop Report

Ambient air pollution is a major public health concern and comprehensive new legislation is currently being considered to improve air quality in Europe. The European Respiratory Society (ERS), Health Effects Institute (HEI), and International Society for Environmental Epidemiology (ISEE) organised a joint meeting on May 24, 2023 in Brussels, Belgium, to review and critically evaluate the latest evidence on the health effects of air pollution and discuss ongoing revisions of the European Ambient Air Quality Directives (AAQDs). A multi-disciplinary expert group of air pollution and health researchers, patient and medical societies, and policy representatives participated. This report summarises key discussions at the meeting

980 nm electroluminescence from ytterbium tris (8-hydroxyquinoline)

We have demonstrated a ytterbium tris (8-hydroxyquinoline) based organic light emitting device giving sharp electroluminescence at ∼980 nm, and demonstrated that it is not a requirement to match the energy of excitons formed on the organic ligands to those of the intra atomic transition within the ytterbium ion to obtain this emission. This may also be true for other rare-earth containing organic molecules thus allowing molecules to be designed for their charge transport properties rather than to match energy levels with the ions. © 2001 Elsevier Science B.V.

The role of health impact assessment for shaping policies and making cities healthier

Health Impact Assessment (HIA) is an important tools to integrate evidence in the decision-making process, and introduce health in all policies. In urban and transport planning, HIAs have been used generally to assess qualitatively urban interventions rather than offering more useful/powerful estimations to stakeholders through quantitative approaches. HIAs could answer various pressing questions such as: what are the best and most feasible urban and transport planning policy measures to improve public health in cities? Also the process on how to get there is often as important as the actual output of the HIA, as the process may provide answers to important questions as to how different disciplines/sectors can effectively work together and develop a common language, how to best incorporate citizen and stakeholder, how different modelling and measurement methods can be effectively integrated, and whether a public health approach could make changes in urban and transport planning
