Health impacts from traffic related air pollution in Danish urban areas
In most of the European cities air pollution has changed in recent years; previously the most serious problem was sulphur dioxide and soot from minor domestic heating plants; this has largely been solved by introduction of cleaner fuels and change in infrastructure. Now the increasing traffic emissions, notably of nitrogen oxides and volatile organic compounds, with the ensuing photochemical air pollution, attract most attention.
Denmark has, for a series of geographical and meteorological reasons, relatively clean air. In urban areas, however, where the emission density is high and the dispersion of pollution is limited, impacts on human health and well-being must be considered. In the planning of a rational abatement strategy, including emission and air quality standards, it is not sufficient to determine pollution levels, it is also important to investigate to what extent people are actually exposed to them. Further, it is necessary to establish the relative contributions from various human activities

Sundhedsmæssig vurdering af luftforurening fra vejtrafik: - med særlig fokus på partikler
En lang række undersøgelser peger på en sammenhæng mellem luftforurening og sundhedsbelastning i byområder. Disse forhold er nærmere diskuteret i rapporten "Sundhedsmæssig vurdering af luftforurening fra vejtrafik", der i foråret 1997 er udgivet som nr. 352 i Miljøstyrelsens serie af miljøprojekter. Blandt de mange forskellige stoffer, som udsendes fra vejtrafik udpeger rapporten de kritiske luftforureningskomponenter. Partikler og i særdeleshed små partikler vurderes som den mest sundhedsbelastende luftforureningskomponent. Derfor fokusseres i det følgende mere detaljeret på kilderne til partikelforurening, forureningens egenskaber og niveauer samt påvirkning af mennesker
Sundhedsmæssige effekter af partikler
Partikleforureningens sundhedsskadelige effekter gar efterhånden været i fokus i en årrække. Indlægget vil søge at give en ajourføring af viden på området, men fokus på en række aspekter hvor der ofte stilles spørgsmål
The applicability of the GHS classification criteria to nanomaterials
The report reviews the applicability of the Globally Harmonised System of Classification and Labelling of Chemicals (GHS) hazard classification criteria to manufactured nanomaterials considering the recent data generated and compiled in the nanomaterial testing program under the OECD Working Party on Manufactured Nanomaterials. In addition, data from the EU NANoREG project, the EU NanoSafety Cluster projects, REACH registrations and publicly available literature were used. The project focused on four nanomaterials and selected health hazard classes. The available test data were evaluated with respect to applicability of the test methods, applicability of the GHS criteria, identified data gaps and uncertainties and need for revision of GHS criteria or guidance. The report also highlights specific issues to be considered when classifying nanomaterials
