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. ...

Is the accuracy of low-cost air quality monitoring systems a valid concern?
Air pollution is on the rise, and it is not just the governments that want to do something about it. Local organizations and industrialists are also asking for data to understand what is responsible for the damage of the air around them. Pollutant dispersion causes subtle yet fatal side effects on public health. Therefore, it becomes essential to understand their concentration levels and what ...

FPI in Cambodia: Our Ambient Air Quality Monitoring Station Is Making a Hit
According to Aqicn, Cambodia ranks 162nd (out of 178 countries) on the Environmental Performance Index for Air Quality. As a leading tourism nation, Cambodia has gained a great economic surge but also witnessed a deteriorating environment. The issue shares mixed reasons. On the one hand is the chain effect caused by gushes of tourists and the outdated local transportation, which keep emitting ...

Application of an ISCST3 model for predicting urban air pollution in the Izmir metropolitan area
A Gaussian atmospheric dispersion model, Industrial Source Complex Short Term (ISCST3), was used to estimate ground-level concentrations of sulphur dioxide (SO2) emitted from source categories of industrial and domestic heating in the city of Izmir, Turkey. Predictions were estimated for the year 2000 across a study area of 80 km x 100 km. Statistical analyses were carried out to evaluate the ...

`Air Permitting for a New Coal-Fired Power Plant,` published in Power magazine, November
Prevention Of Significant Deterioration (PSD) Construction of any new source, including a greenfield power plant, is subject to New Source Review (NSR). If the source is located in an attainment area, it will also trigger Prevention of Significant Deterioration (PSD) permitting, as required by the Clean Air Act (CAA) for major stationary sources of air pollution in attainment areas. A major ...

Location of Low-cost Sensor-based Air Quality Monitoring Devices
Monitoring the pollutant concentration is fundamentally important to develop and evaluate pollution control strategies. It enables us to understand the trend and extent of pollution by identifying pollution sources, and thereby indicating where more efforts are needed. It is important to ensure that the measured air quality provides adequate and accurate information. One of the key factors ...

How Does a Gas Analyser Work?
Whatever you want to detect, you need to identify a property of the object that is easy-enough to measure. When it comes to monitoring and analysis of gaseous species (atoms or more commonly molecules), it turns out that it often is possible to utilize the optical properties of the gas. You need a light source, a light detector, and a characteristic behaviour of the gaseous species in question ...
