Air pollution monitoring for mines: a solution for cost effective measurements
Air pollution is one of the main environmental problems to be addressed by the EU. In order to foster sustainable development and mitigate climate change, it is therefore important to provide national and regional authorities with appropriate measures to reduce criteria pollutants (PM 10, PM2.5, O3, CO2, SO2 and NOx) concentrations in air. Many cities are not able of meeting the implemented EU ...

Air pollution and the influence of sources on Paulinia (Brazil) and surroundings
The air quality in the industrial area and surroundings of the city of Paulinia (state of Sao Paulo, Brazil) has been investigated by analysing the concentration of air pollutants (SO2, PM10, NO, NO2, CO and ozone) and identifying the main sources of air pollution. A mobile pollutant monitoring unit was used to collect the data at five different sites from November 2000 to July 2002. Critical ...

Basic Difference Between AAQMS and CAAQMS
Air, being an invisible and dynamic medium, it is difficult to know if the air quality of a region is as per the air quality standards. It is imperative to monitor the air quality frequently to assess the pollution level in accordance with the National Air Quality Standards set under the Air (Prevention and Control of Pollution) Act, 1981. Air monitoring is done to measure the pollution level of ...

An ambient air quality monitoring network for Buenos Aires city
This paper proposes an objective methodology for designing a multi-pollutant urban air-quality monitoring network to detect concentrations greater than reference concentration levels (CL). The network design includes both air quality simulation and an objective analysis based on monitoring tasks. The proposed methodology is applied to the city of Buenos Aires. Pollutants of concern are nitrogen ...
