honeybees

German officials are trying a novel approach to monitor air quality at airports — so-called “biomonitoring” by honeybees. In an effort to gauge air pollution levels from jet exhaust and ground transportation vehicles at Düsseldorf International Airport and several other airports nationwide, officials test honey from honeybees kept at the airports. In a recent test of honey collected from some 200,000 honeybees, officials confirmed that levels of some hydrocarbons and heavy metals were well below national safety standards. The honey, called Düsseldorf Natural, is then given away as gifts.
