In Jiaxing, east China's Zhejiang Province, a very special team of volunteers is busy nosing out trouble - the "odor inspectors". With a task set to follow their noses, they're always on the trail of the tell-tale signs of industrial pollution so that companies can respond proactively at the first whiff of trouble. And with everyone working together for cleaner air, this approach to the problem of pollution is proving to be fresh in every sense of the word.
