Assessment of air pollution using air pollution tolerance index (APTI) by two species plant (Conocarpus lancifolius) and )Dodonaea viscosa) in babylon provinus

Abstract

Plants play as filters to reduce air pollution that produce from the Brick Factory and also as bio-indicators of air quality can be divided plants for sensitivity or tolerance to air pollutants because the sensitive plants can serve as bio-indicator and the tolerant plants as sink for controlling air pollution in industrial areas. Biochemical parameters namely relative water content, leaf extract pH, ascorbic acid, and total chlorophyll, were estimated Air Pollution Tolerance Index (APTI) for two plants each at the first site (S1) in the direction of predominant winds and the second site (S2) in opposite the direction of predominant winds. The results showed the plant Conocarpus lancifolius can be tolerant towards air pollution in comparison with plant Dodonaea viscosa that consider as sensitivity to air pollution.
