An Assessment Of Air Pollution Tolerance Indices Of Some Plant Species Grown In And Around An Industrial Area In Guwahati, Assam, India
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 10
Abstract
Air pollution tolerance index (APTI) of 24 plant species growing in a waste metal recycling industrial estate at Boragaon, Guwahati, Assam were determined for a period of 6 months by evaluating the relative water content, leaf extracts pH, total chlorophyll content and ascorbic acid content. The result indicates that different plants exhibit varying levels of tolerance and sensitivity to three major air pollutants (PM10, SO2 and NOx). In the study, it was observed that highest values of APTI and ascorbic acid contents were recorded only in two plant species, Catharanthus roseus and Melia azedarach revealing the tolerant capacities of these plants to sustain their growth and survival in polluted environment as compared to other plant species.
