Air quality and climate change are among the biggest societal challenges that we face today. According to World Health Organization, air pollution is the single greatest environmental risk. An estimated 7 million people globally die prematurely each year due to air pollution. The estimated economic costs of air pollution in the Europe are well over €20 billion a year. Atmospheric free radicals, particularly hydroxyl (OH) and nitrate (NO3), are the drivers of chemical processes that determine atmospheric composition and thus influence local and global air quality and climate. Therefore, detecting and understanding the behaviour of radical species in the atmosphere is important. Detection of radicals is challenging because of their low mixing ratios, short lifetimes and fast surface losses during sampling. Current techniques for measuring radicals, which are based on spectroscopic and mass spectrometric methods, are technically complex, cumbersome and expensive. As a result, the measurement of atmospheric radicals is far from routine and only a few research groups worldwide can perform them in a very limited number of geographic locations. This presentation will provide an overview, and a discussion of the latest results, from the recently funded EU project ‘RADICAL’ which aims to develop small, low-cost sensors to electrically detect short-lived atmospheric radicals. Although challenging, RADICAL sensors not only have the potential to be rolled out on a global scale but can also be adapted to detect other important atmospheric gases.
