Researchers from BEST-COST reviewed epidemiological evidence that links long-term exposure to road traffic, railway, and aircraft noise with different cardiovascular health outcomes, to derive exposure-response functions.
Air exchange rates, infiltration factors and indoor-generated concentrations of nitrogen dioxide (NO2) were estimated using a simplified mass-balance model (Healthvent approach) and the French database (CNL2) from the indoor environmental quality observatory (OQEI). The data used contained information on 571 dwellings measured over one week between 2020 and 2023 in various regions of France.
The results of this study provide reference values that can be used when actual values are not available and for dwelling conditions are similar to those of the French dwellings.
