Testing labs in Sevres-Anxaumont

ACTINIUM is a French service company specializing in air quality consulting and measurement, headquartered at 58, Route de Saint-Julien l'Ars, 86800 Sèvres-Anxaumont, in the Vienne department of western France. With more than 20 years of documented experience in the air quality sector, ACTINIUM supports industrial operators, facility managers, health and safety committees (CHSCT), and public-sector clients in addressing occupational exposure compliance, indoor environment quality, and atmospheric emissions challenges arising from the use or release of hazardous chemical substances. The laboratory's flagship service is the regulatory control of occupational exposure to hazardous chemical agents (Contrôle réglementaire d'exposition aux agents chimiques dangereux). ACTINIUM holds COFRAC accreditation — issued by the Comité Français d'Accréditation, France's national accreditation body, whose testing laboratory scope operates under ISO/IEC 17025 — for professional exposure measurements in the discipline of industrial hygiene. Operating under the French ministerial decree of 15 December 2009 governing technical controls of occupational exposure limit values (valeurs limites d'exposition professionnelle, VLEP) at workplaces, ACTINIUM is authorized to conduct fully accredited regulatory measurement campaigns encompassing: development of a tailored sampling strategy; in-situ collection of personal and area air samples; laboratory analysis of the collected sampling media; and preparation of a formal exposure diagnosis report. Individual phases of this workflow may also be commissioned separately under COFRAC scope when the objective falls outside the mandatory regulatory framework. Ventilation assessment and indoor air system performance constitute a second major service area. ACTINIUM measures air suction velocities and volumetric flow rates (débits) across multiple installation categories, including rooms with specific pollution sources, rooms with non-specific pollution, localized capture devices (dispositifs de captage), laboratory fume cupboards (sorbonnes), and general extraction hoods (hottes). These measurements verify that mechanical ventilation systems maintain adequate pollutant dilution, support compliance with workplace hygiene codes, and inform decisions about system upgrade or resizing. ACTINIUM conducts comprehensive Sick Building Syndrome (le syndrome des bâtiments malsains) investigations, combining building audits with physico-chemical parameter measurements: fresh-air flow rates in ductwork, relative humidity, ambient temperature, volatile organic compound (COV/VOC) concentrations measured by screening methods for identification and semi-quantification, and carbon dioxide (CO2) concentrations used to compute a confinement index. These multi-parameter surveys are used to diagnose root causes of occupant discomfort, fatigue, or respiratory complaints in offices, educational buildings, and commercial premises, and to recommend remediation measures. For indoor swimming pool facilities (piscines couvertes), ACTINIUM performs both regulatory and voluntary air quality monitoring designed to protect swimming instructors (maîtres-nageurs) and other staff from disinfection by-products. Measured analytes include nitrogen trichlorides (trichloramines — the primary chlorinated pool air contaminant), and the suite of trihalomethanes (THM): chloroform (trichloromethane), bromoform, dibromochloromethane, and bromodichloromethane. Air volume flow rates — fresh-air supply and renewal velocity — are also measured to assess whether ventilation meets regulatory renewal-rate requirements. Odor measurement (mesure d'odeur) services apply olfactometry protocols for both interior environments and exterior ambient air, enabling quantification of odor intensity at emission sources and in surrounding receptor areas. This capability serves industrial operators, wastewater treatment sites, composting facilities, and agro-food plants seeking to characterize airborne nuisances for regulatory submissions or community impact assessments. On the environmental side, ACTINIUM addresses fixed-source atmospheric emissions (émissions de sources fixes, rejets atmosphériques) and ambient air quality surveys — the former in partnership with an accredited stack-testing organization — as well as atmospheric deposition (retombées atmosphériques) monitoring. ACTINIUM's consulting and self-monitoring (auto-contrôle) offer rounds out its portfolio. For clients who prefer to internalize routine, non-regulatory pollutant surveys, ACTINIUM supplies the full methodology, calibrated sampling pumps, analytical substrates, data forms, and direct-reading analyzers needed to carry out reproducible in-house measurements at minimal cost. The company also provides campaign optimization advice to help industrial clients structure their mandatory regulatory measurement programs efficiently, and delivers risk-assessment studies (évaluation des risques) and French mandatory single-risk documents (Document Unique d'évaluation des risques, DUER) in collaboration with specialist partner firms. This combination of accredited laboratory measurement, field sampling, consulting, and client enablement positions ACTINIUM as a comprehensive, long-tenured partner for any organization managing airborne chemical hazards in France.
