Pollutant Metrology
The aim of works of the Pollutants Metrology Department relates to the prevention of occupational diseases. They mainly concern the development and validation of methods and techniques for the assessment and characterization of occupational exposure to gaseous pollutants and aerosols of chemical and biological agents in the atmosphere of workplaces
Pollutant metrology facilities
The department has facilities for generations of controlled atmospheres making it possible to reproduce as much as possible the working atmospheres to develop methods and tools in the most representative situations of real situations for organic gases and vapors, semi-volatile aerosols, nanoparticles, particles and fibers, biological aerosols… Providing simple methods, easy to use, reliable, robust and the least expensive possible is a priority objective of the Pollutants Metrology department. All the methods are available in the MétroPol database available on the website www.inrs.fr.

Metrology of exposure to organic pollutants
The laboratory is developing methods for the qualitative and quantitative analysis of occupational exposure by organic compounds: exposure by inhalation and skin exposure. All the methods developed in the laboratory, on benches for generating gases, vapors and semi-volatile organic aerosols, are systematically validated in real situations, in companies. The work focuses on improving existing methods, developing new approaches and new devices: surface sampling by proposing a stabilized methodology, sensor for measuring individual exposure such as for example to ozone, new sampling support specific to nitrous oxide, measurement of semi-volatile aerosols, passive sampling of pollutants, supercritical CO2 desorption. The laboratory has a fleet of devices adapted to the needs and corresponding to the techniques conventionally used by exposure measurement laboratories.

Risk and exposure assessment
The laboratory offers chemical and biological risk assessment methods. By evaluating the occupational populations exposed through sector surveys by sector, profession or product, the laboratory identifies professional situations for which preventive actions are a priority. It also develops chemical and biological risk assessment methods and methods for establishing intervention and sampling strategies. The laboratory uses methods of collecting information through surveys and questionnaires. It operates and uses the COLCHIC and SCOLA occupational exposure databases to supplement the information obtained by surveys of companies. These same data are made available to interested persons via the SOLVEX tool available on the website www.inrs.fr.

Laboratory for inorganic analysis and characterization of aerosols
The laboratory develops methods for the qualitative and quantitative analysis of pollution by mineral, particulate, fibrous or gaseous products. The methods developed in the laboratory, for sampling and analysis in air and on surfaces, are systematically validated in real situations, in companies. The laboratory's work also concerns studies of specific industrial pollution and the assessment of occupational exposure. The laboratory's activities are in particular the characterization by electron microscopy of particles including nanometric particles and fibers including asbestos, chemical characterization of particles according to their size, passive sampling of fibers, bioaccessibility of particles, determination physico-chemical parameters of powders influencing aerosolization, the development of alternative measurement methods using specific sensors. The laboratory generates samples of asbestos fibers and organizes an intercomparison test.

Aerosol metrology
The laboratory studies the physical properties of aerosols in relation to their action on the respiratory tract. It develops methods and equipment for sampling and monitoring pollution by biological and physical aerosols of all sizes: from nanometric to several tens of micrometers. The methods are validated during interventions in companies. It completes the knowledge of the physics of aerosols by studying their properties and their size. The laboratory's work concerns the sampling, on-site measurement and analysis of microbiological aerosols, bacteria, molds or fungi, nanometric aerosols, the development of sensors for real-time measurement of nanometric aerosols, the means and methods for direct measurement of aerosols. The laboratory validates devices for sampling microbiological and physical aerosols, it also develops knowledge about the nature of aerosol exposure depending on the processes and the work environment.
