ABSTRACT

 

For evaluation of Air Pollution tolerance Indices of plants, four parameters namely ascorbic acid, leaf extract pH, relative water content and total chlorophyll were determined and computed in formula to get the susceptibility levels of plants. Plants having high index value were sensitive. The former can serve as sink and the later as indicator for the abatement of air pollution in industrial area. Results revealed Ficus glomerata to be tolerant and Acacia nilotica to be sensitive species.

 

Keywords : Ascorbic acid, Ecological model, APTI value, Economic value, Tolerance.
