General Metropolitan Environment
A random sampling study of the Air Quality Index (AQI) of twenty stations within the city indicated scores that ranged from 76-314, suggesting heavy to severe air pollution around areas of traffic concentration. Major pollutants contributing to Bangalore's high AQI score include nitrogen oxide, Suspended Particulate Matter (SPM) and carbon monoxide.
The Bangalore metropolitan area, referred to as the Garden City of India has an abundance of fauna and flora. The city has two nationally renowned botanical gardens—Cubbon Park and Lal Bagh. A majority of the trees in the city are big to medium canopy trees with girths above 40 cm. Coconut trees form a large minority of the tree population in the city.
In 2003, the Battelle Environmental Evaluation System (BEES) index used to evaluate environmental components was used to rate Bangalore's physical, biological and socioeconomic parameters. The results are summarized in Table 1.
