QAI-Sport project: Indoor air quality in sports facilities - Characterization of exposure to emerging VOCs and SVOCs and to micro-organisms

Elodie Surget

Résumé

The quality of indoor air in sports facilities is still poorly known and studied. However, the intense activity associated with sport can lead to an increase in exposure through inhalation, breathing rate acceleration, ingestion of resuspended dust, and transcutaneous migration facilitated by sweat. The configuration, management and maintenance of premises can also contribute to a deterioration in indoor air quality in sport centers. These include, for example, the occupancy rate of rooms, poor ventilation management, the presence of synthetic floor coverings and technical materials that emit pollutants or favor the development and persistence of pathogenic micro-organisms such as coronavirus. The QAI-sport project (2022-2024), funded by ADEME (the French Agency for Ecological Transition), proposes to characterize exposure to volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs) and microbiological contaminants (molds, viruses and bacteria) by studying around ten sports facilities for different activities (martial arts, weight-lifting, motricity in preschools). The project is presented here, along with its methodology and main objectives. Initially, targeted and non-targeted analyses of these agents will be carried out under occupied and unoccupied conditions. Particular attention will be paid to identifying emerging contaminants, substances that are unregulated or unexpected in these environments, and to highlighting the main families of pathogenic micro-organisms. An in-depth study, carried out on a selection of three rooms, will then make it possible to study the sources and distribution of contaminants (VOCs, SVOCs and micro-organisms) between the gaseous and particulate phases of the air, settled dust and materials’ surfaces. In view of the recent pandemic, the project will also include specific research into Sars-CoV-2. Exposure to biocides used against this virus will be assessed as well. For SVOCs, the data obtained will be integrated into a model to predict the behavior of these pollutants in indoor environments. Finally, a study of the migration of VOCs and SVOCs in sweat and synthetic saliva will complete the results for a complete and detailed assessment of the exposure routes to these compounds.
