Dioxin emissions and soft-tissue sarcoma: results of a population-based case-control study.

International audience; BACKGROUND: In 1998, the French Ministry of Environment revealed that of 71 French municipal solid waste incinerators processing more than 6 metric tons of material per hour, dioxin emission from 15 of them was above the 10 ng international toxic equivalency factor/m3 (including Besançon, emitting 16.3 ng international toxic equivalency factor/m3) which is substantially higher than the 0.1 international toxic equivalency factor/m3 prescribed by a European directive of 1994. In 2000, a macrospatial epidemiological study undertaken in the administrative district of Doubs, identified two significant clusters of soft-tissue sarcoma and non Hodgkin lymphoma in the vicinit…

Using LUTI models to assess the impacts of daily mobility on noise pollution

Noise in urban areas: How does the definition of "neighborhood" impact exposure assessment?

International audience; Environmental epidemiological studies commonly quantify subjects' noise exposure level in their neighborhood. How this neighborhood is defined can vary across studies, leading to different approaches whose impacts on exposure levels remain unclear. This article examines the impact of the neighborhood's definition on environmental noise exposure estimates. L Aeq,24h exposures in the vicinity of 10,825 residential buildings were estimated using a high-definition noise map, built on a middle-sized French city. Various definitions of neighborhood (address point, façade, buffers, and official zoning) were used to produce different exposure estimates. Influence of urban en…
