Determining the leakage rates of halogenated refrigerants from operating mobile air conditioning systems (MACs) is a challenging task. Here, researchers take advantage of a heavily trafficked tunnel with a traffic flow of over 40,000 motor vehicles per day in south China. They carried out measurements in 2014 on hot and humid days, and therefore, it is reasonable to assume that essentially all of the MAC units would be turned on to ensure the thermo-comfort of the occupants. Thus, they obtained the leakage rates of the three most important refrigerants from the operating MACs aboard the on-road vehicles. [Source: Environmental Science & Technology Letters]
