[单项选择]Although many of us may feel air-conditioners bring relief from hot, humid or polluted outside air, they pose many potential health hazards. Much research has looked at how the movement of air inside a closed environment—such as an office building—can spread disease or expose people in the building to harmful chemicals.
One of the more widely publicized dangers is that of Legionnaire’s disease, which was first recognized in the 1970s. This was found to have affected people in buildings with air-conditioning systems in which warm air pumped out of the system’s cooling towers was somehow sucked back into the air intake (通风口), in most cases due to poor design. The warm air, filled with bacteria, was combined with cooled, conditioned air and was then circulated around various parts of the building. Studies showed that even people outside such buildings were at risk if they walked past air exhaust pipes.
Large air-conditioning systems add water to the air they circulate b
A. It was the most widely concerned office hazard.
B. It can affect people both inside and outside the building.
C. It happens only in air-conditioned office buildings.
D. It does not develop in well-designed buildings.
