Abstract

This study aims to better understand the spatial and temporal distribution of air pollutants in indoor working environments. We explore utilizing this information for air quality monitoring by developing and building a low-cost sensor network in multiple real working environments. Sensor networks were installed in different scenarios: indoors at a steel factory, and on a cruise ship’s car deck. The stationary sensor networks are composed of multiple custom sensing nodes. Each node is equipped with low-cost sensors to assess gaseous components, particulate matter, temperature, and humidity. Air quality measurements using validated traditional methods and high-end portable direct-reading instruments are performed stationary and mobile. Mobile devices carried by workers and unmanned aerial/ground vehicles complement the measurements by the stationary sensor network. The results consist of evaluations carried out by combining the sensor data, contextual information, and the results obtained with traditional exposure assessment methods. Can this data fusion be used to assess exposure and target risk management measures? In this work, we discuss the feasibility of the available sensors for air quality measurements and further explore the suitability of pollutant concentration maps for exposure assessment and for planning control measures.
