Air pollution is a threat to public health in the 21st century. In Latin America, more than 100 million people are exposed to air pollution. There is a gap in air quality monitoring in cities around the world. Environmental risk factor monitoring and forecasting systems are strategic for the adoption of preventive measures and health surveillance alerts. The engagement of stakeholders is crucial to develop strategies to control air pollution. Objective: To define air quality and health risk indicators relevant to health surveillance and civil defense, allowing the mapping of areas of higher risk and vulnerability for the population. Methodology: The SOPRAR project was built through an articulated intersectoral mobilization, scientific institutions, private and public sector. The project includes the configuration of emission, chemical, and transportation models to represent the local conditions. The system operates based on CHIMERE model runs (48h forecast) forced by weather forecast simulations (WRF) performed by the local civil defense, integrating a updated emissions inventory. Model results, pollutants concentration maps and air quality index, will be available by WEB service. A tailored health risk indicator will be developed to make the SOPRAR system. The project is committed with the technology and know-how transfer to local actors. Results: The emission inventory was updated based on available local data regarding traffic, road network, industries processes and land use. Total emissions in the Salvador Metropolitan Region corresponds to 3327.03 tons/year of Particulate Matter, 14964.32 tons/year of Sulfur Dioxide, 75572.28 tons/year of Carbon Monoxide, 24756.30 tons/year of Nitrogen Oxides and 21756.64 tons/year of Volatile Organic. Considerations: The system is as an innovative management tool based on urban environment air quality modeling and will provide support for the activation of air quality protection and communication service protocols for use in research, public policies for primary care and health surveillance.
