This report presents a review of sensors and technologies that are capable of detecting and monitoring air pollution in particular, volatile organic compounds. The following categories of sensor technologies were reviewed: 1) mass sensors, 2) electrochemical sensors and 3) optical sensors. A summary of the advantages and disadvantages of each sensor technology identified from the literature search is given. Based on the potential for long-term monitoring applications the most viable sensors for in-situ chemical sensing appear to be electrochemical sensors (specifically conductometric sensors), fiber-optic sensors, surface-acoustic-wave sensors. However, very few chemical sensors have been successfully demonstrated in real-time, continuous, in situ applications.
