EcoSoft develops a wide range of services related to the environment in general, with emphasis on the management of air emissions, air quality and meteorology.
Air quality studies are essential and mandatory part of the Environmental Impact Assessment for companies with significant emission of air pollutants. These studies also can assist for choosing the most effective environmental control systems as well for design of the air quality monitoring networks.
Concentrations of PM10 – Malaysia
We use a state of art mathematical models, approved by internationally accredited environmental agencies such as the CMAQ model (Community Multi-scale Air Quality Model), CALPUFF, AERMOD, among others.
EcoSoft has 20 years of experience in the use of atmospheric dispersion models, having performed more than 300 modeling works. We have our own computer cluster with high processing capacity and skilled professionals for the implementation and interpretation of results.

Inventories may include stationary and mobile, point and diffuse sources, considering all relevant pollutants or characteristic of the company and the region, such as particulate matter (TSP, PM10, PM2,5), sulfur dioxide, nitrogen oxides, carbon monoxide, volatile organic compounds, hydrocarbons, odorous gases, fluorides, heavy metals and others.
Emissions from marine aerosols, atmospheric discharges, biogenic emissions, wind erosion of soil particles and surfaces, forest burning, among others can also be inventoried. EcoSoft also has extensive experience in air emissions inventories in oil extraction, refineries, steel, mining, pulp and paper, chemical, power generation, transportation (trains, ships, trucks and off-road machinery), as well as inventories of urban emissions, such as vehicle, evaporative, household and commercial emissions, among others.

Scenario of mobile source emission
EcoSoft owns next-generation mobile automatic monitoring stations that enable a continuous measurement of air pollution levels and weather conditions, using methods and equipment approved by the USEPA. The stations are leased by the required time (minimum of 30 consecutive days), and EcoSoft provides the transportation, installation, operation, maintenance and uninstallation of the station, giving the customer the detailed report of measurements with the interpretation and analysis of the generated data.

Change in concentration of O3, NOx and VOC along 24 hours
To the current situation are added the increments of pollutant concentrations due to the implementation of planned projects calculated by mathematical modeling, verifying the sustainable maintenance of air quality across the region of interest and the compliance with the air quality standards.
Industrial zone continuously monitored about air quality
The optimization techniques employed in the designs allow the maximization of network coverage measurement area and minimize the number of stations and sensors used, given a specified coverage efficiency.
EcoSoft has designed more than 40 optimized air quality monitoring networks in Brazil, Africa and Asia, including big metropolitan areas like Belo Horizonte, Rio de Janeiro, Vitória, São Luís, among others.
Monitoring coverage of PM10 – Rio de Janeiro
It is the analysis of the operating conditions of a specific production process and its control systems pollutant emissions, verifying the safety limits for its operation.
If necessary and viable, solutions to extend the pollutant retention capacity of the installed control system and / or required additional control measures are indicated.
Besides the weather forecasting, this type of modeling is widely used for the production of data to be used in analytical and numerical models of atmospheric dispersion, such as AERMOD, CALPUFF and CMAQ.

Inventories include direct (Scope 1) and indirect (Scope 2 and 3) emissions, allowing the identification and qualitative characterization of the nature of Greenhouse Gases (GHG) attributable to the enterprise complex inventory, including GHGs covered by the Kyoto Protocol :
(i) carbon dioxide,
(iii) nitrous oxide,
(vi) Sulphur hexafluoride.
