This unique study, based on an innovative approach, has been published in the journal Environment International. It included data from 11,382 participants belonging to the Gazel cohort who were living in rural areas throughout France, a cohort that had been followed up for 20 years. The data on mosses came from the BRAMM biovigilance programme, which collects and analyses moss samples from areas all over France situated at a distance from the country's largest industrial and population centres. These samples are analysed in the laboratory to measure the presence of 13 elements: aluminium, arsenic, calcium, cadmium, chromium, copper, iron, mercury, sodium, nickel, lead, vanadium and zinc.

"There have been very few studies on the health effects of airborne metal pollutants, partly because of technical limitations, such as the lack of stations measuring air pollution. We thought that moss, because of its capacity to retain these metals, would be a useful tool for estimating the atmospheric metal exposure of people living in rural areas," explains Bénédicte Jacquemin, ISGlobal and INSERM researcher and last author of the study.

The scientists constructed a mathematical model based on the geolocation data for each moss sample and the results of the BRAMM laboratory analysis. This model was then used to map the exposure of each participant to...
