Urban gardens to monitor air pollution

Researchers from Universidad Polit├ęcnica de Madrid in collaboration with the University of Copenhagen have assessed the use of edible plants for the biomonitoring of atmospheric pollution.

Pollutant

A pollutant is a waste material that pollutes air, water or soil, and is the cause of pollution.

Three factors determine the severity of a pollutant: its chemical nature, its concentration and its persistence. Some pollutants are biodegradable and therefore will not persist in the environment in the long term. However the degradation products of some pollutants are themselves polluting such as the products DDE and DDD produced from degradation of DDT
