Health risk assessment for your project

Air quality and health are closely linked. A Health Risk Assessment (HRA) describes the health consequences of exposure to one or more hazardous agents. We rely on the best available scientific data, complemented where needed by assumptions consistent with current knowledge.

Based on the air-quality impact study of your project’s atmospheric releases, NUMTECH also performs the quantitative health risk assessment.

Our experts help define strategies that ensure no health risk to populations and facilitate acceptance of the file by the authorities.

Évaluation des impacts sanitaires liés à la pollution de l’air

A proven methodology

NUMTECH assesses pollutant health impacts using the latest methodological recommendations (INERIS guides, recommendations by ANSES and HCSP, etc.) and relevant sectoral guidance.

We address all issues: chronic and acute risks, inhalation and ingestion pathways.

Robust tools

Our specialized engineers use the most appropriate tools to determine population exposure.

  • Inhalation exposure : Assessed via atmospheric dispersion modeling, notably with the ADMS software. Widely used for ERS files; we are the official distributor and experts of this tool.
  • Ingestion exposure : Assessed using the MODUL’ERS software developed by INERIS.

Environmental study

Interpretation of environmental media status

A preliminary step to HRA, the Interpretation of Environmental Media (IEM) defines the state of the media into which a project is inserted and checks compatibility with identified uses. It is based on environmental measurements performed with our metrology expert partner.

Environmental compliance

Environmental Monitoring Plan: tracking site impacts

Generally required by the operating decree, the Environmental Monitoring Plan (PSE) tracks an installation’s impacts throughout its lifetime and raises alerts if degradation is observed.

Setting up the EMP

Closely linked to the ERS, the EMP is built from IEM conclusions and inputs collected during the ERS. It groups periodic measurements across the various receiving media.

Based on dispersion modeling and the IEM/ERS conclusions, NUMTECH supports your EMP implementation strategy.

Updates

Periodically, and in line with environmental authority recommendations, NUMTECH updates the spatial strategy defined in the EMP, accounting for site changes, surroundings and meteorological conditions.

F. A. Q

Do you have any questions?

FAQ santé des populations – questions fréquentes
No. We collect all data external to the site. For unknown parameters, we consult national or international databases. In line with the prudence and transparency principles of HRA, all assumptions are detailed and conservative choices are applied.
IEM is indeed based on measurements of media potentially affected by site or project emissions. However, if representative measurements are already available, they can be used.
