Low-Cost Ambient Air Quality Monitoring System
There is a plethora of scientific reports & research by WHO, Global burden of disease, IPCC(Intergovernmental Panel on Climate Change) on the harmful effects of air pollution. Day by day increasing pollution level mandates some air standards to be in place looking at the dire need for air quality management. We need to try and recede the pollution below the ‘threshold effect ...

Methodology for developing an air quality index (AQI) for Tunisia
Air quality index (AQI) is a quantitative tool through which air pollution data can be reported, providing information on how clean or polluted the air is. Several countries employ some type of air quality index to communicate the quality of their air. Some of these systems rely on relating measured (monitored) or predicted concentrations of air pollutants (results of modelling system). In this ...

Location for Air Quality Monitoring System Plays a Critical Role in Sensor Accuracy
Air quality is a complex, multi-faceted topic with many nuances. Air is dynamic. That means it moves continuously. And it carries its pollutants wherever it goes. So, it becomes quite difficult when it comes to monitoring the air quality of a particular ...

Evaluation of dispersion models for an urban environment: an example from Stockholm, Sweden
An air quality management system has been in operational use in the city of Stockholm, Sweden, for several years. In the system there are, in addition to databases for measurements of air pollution and meteorological parameters and emission data, several dispersion models. The models include a Gaussian and a Eulerian (grid) type of dispersion model. An evaluation of the Gaussian and the grid ...

Passive vs Active Sampling for Sensor-based Ambient Air Quality Monitoring
Air pollution with its cascading effects across the population has become a serious matter of concern. To address this air pollution problem, availability of accurate and reliable air quality data is crucial. The quality of air monitoring depends upon how the sample of air is collected and how it is analysed. This paper majorly focuses on passive vs active sampling for air quality monitoring. ...

Air Pollution Monitoring in Tunnels and Parking Lots
Thousands of miles long tunnels support transportation of millions of vehicles around the world. Tunnels are crucial road infrastructure, especially in mountainous regions. They save a lot of time and fuel and provide reliable rail and road transportation in all seasons. Incessantly increasing vehicular congestion results in the construction of underground parking facilities. With ever-increasing ...

Evaluation of AirGIS: a GIS–based air pollution and human exposure modelling system
This study describes in brief the latest extensions of the Danish Geographic Information System (GIS)–based air pollution and human exposure modelling system (AirGIS), which has been developed in Denmark since 2001 and gives results of an evaluation with measured air pollution data. The system shows, in general, a good performance for both long–term averages (annual and monthly averages), ...

Predicting air quality in Uberlandia, Brazil, using linear models and Neural Networks
Particulate air pollution causes a wide range of effects on human health, including disorders of the respiratory and cardiovascular systems, asthma and can cause mortality. Hence, the development of an efficient air quality forecasting and early warning system is an obvious and imperative need. The objective of this work was to investigate this forecasting possibility using linear models (such as ...
