Armand ALBERGEL– aalbergel@aria.fr

ARIA TechnologiesARIA Technologies was founded in 1990 by a

group of researchers from the R&D department of EDF, the French electricity board.

It is now an independent company, leader in its field in Europe. Its headquarters are located near Paris, with offices in France and a sister company, ARIANET, in Milan, Italy.

One focus: modeling the atmospheric environment •from building scale to continental scale •from simple screening models to full-blown CFD solutions•keeping consulting, software, systems and training tightly linked•with an international and open approach, close to top R&D centres.

Application domains

Environmental Impact Assessment

Since 1998, ARIA Technologies has taken part in over one hundred air pollution dispersion studies related to industrial sites Power plants, incinerators, Waste Treatment facilities.

Validation vs. experimental data

3 different models

Environmental Impact AssessmentHealth Risk Assessment

•Identification of dangers:•chronic toxicity•carcinogenic risk

•Dose-response relationship analysis: •threshold toxicants known as "systemic toxics" •non-threshold toxicants such as carcinogenic pollutants

•Calculation of exposure: •inhalation•ingestion

•Assessment of health risk: •Threshold toxicants: danger ratio •Non-threshold toxicants: probability of developing a cancer

• Manage exposure and risk• Broadcast results• Evaluate health risks

Regulatory constraints

Collective air pollution control in an industrial basin

Share the responsibility and the investments on air concentration bases and not only on total year emissions

Ambient air monitoring networks are generally not enough dense to cover the whole area

Individual air control for some industries

Example of a domestic waste incinerator : Monitoring the impact in the vicinity of the installation (Art 30 et 31 of the law 20 September 2002 concerning burning installation of hazardous and non-hazardous waste) :

Initial diagnostic : before the installation opening

Between 3 and 6 months : after the installation runing

Routine update : at least annually

Reference : INERIS (mandated by the French MOE) « Methode de surveillance des retombées des dioxines et furanes autour d’une UIOM » 2001 10

Need of an on-line Supervision tool

A global tool to :

Optimize the atmospheric environment supervision

Improve internal and external communication (HQ and quick adaptability): neighborhood , Local authorities, routine reporting, nongovernmental association…

Analyze, understand and explain the impact of their own releases

How ?

On-line concentration and deposition of main pollutants (NO2, dioxines, heavy metals…) considering real emissions and actual meteorological data

Comprehensive Maps Help to design measurement campaign Ready to run in case of accidental / exceptional releases

A detailed knowledge of the impact of their own installations

11

Need of an on-line Supervision tool

Editing results every 3 hours:

concentration and deposition maps

summary table of values

Continuous update of computational values on key points:

daily,MonthlyAnnually (main statistics as centils)

Time series of meteorological data and emission

Data base backup for all data and results (Yearly base)

Detailed run on request (peak, accidental or exceptional release)

Optimization (measurement, day-to-day reporting,…) of the supervision

12

Where are the difficulties ?

Numerical geographical data OKTopography and land use largely available world wide now and especially in EuropeGIS are widely used

Meteorological data OKBetter sensors and denser networkNumerical forecast and analyses better qualityProgress on Meso-scale modeling

Emissions OK ?Better understanding using ‘universal’ classification like SNAP and emission factorsSelf-monitoring emission CEMS or PEMS

Computational and numerical network OKPower increased on low cost computerInternet / intranet / ADSL communication

Numerical techniques become central
