Monitoring Excess Exposure to Air Pollution for Professional Drivers in London Using Low-Cost Sensors

Gas Sensors for Monitoring Air Pollution

The air pollution caused by exhaust gases from automobiles has become a critical issue. In some regions, fossil fuel combustion is a problem as well. The principal gases that cause air pollution from automobiles are nitrogen oxides, NOx (NO and NO2), and carbon monoxide (CO). Because NOx gases with sulfur oxides (SOx) emitted from coal fired plants cause acid rain and global warming and produce...

The next generation of low-cost personal air quality sensors for quantitative exposure monitoring

Advances in embedded systems and low-cost gas sensors are enabling a new wave of low-cost air quality monitoring tools. Our team has been engaged in the development of low-cost, wearable, air quality monitors (M-Pods) using the Arduino platform. These M-Pods house two types of sensors – commercially available metal oxide semiconductor (MOx) sensors used to measure CO, O3, NO2, and total VOCs, a...

Supplement of The next generation of low-cost personal air quality sensors for quantitative exposure monitoring

Air pollution exposure monitoring and estimating

This paper presents an integrated exposure monitoring system, based on an expansion of existing air quality monitoring systems using dispersion modelling. The system allows: (1) identifying geographical areas whose inhabitants are most exposed to ambient pollution; (2) identifying how many people in an area are exposed to concentrations of pollution exceeding air quality guidelines; (3) describ...

The use of electrochemical sensors for monitoring urban air quality in low-cost, high-density networks

Measurements at appropriate spatial and temporal scales are essential for understanding and monitoring spatially heterogeneous environmentswith complex andhighlyvariable emission sources, such as inurban areas. However, the costs and complexity of conventional air quality measurement methods means that measurement networks are generally extremely sparse. In this paper we show that miniature, lo...
