Abstract

The study examined air pollution tolerance indices (APTI) of ten plant species around the Erhoike-Kokori oil exploration station of Delta state. Four physiological and biochemical parameters; leaf relative water content (RWC) ascorbic acid content (AA), total leaf chlorophyll (TCh) and leaf extract pH were used to compute the APTI values. The result showed that combining variety of these parameters gave a more reliable result than those of individual parameter. The order of tolerance is as follows: Psidium guajava < Elaesis guineensis < Musa paradisiaca < Bambosa bambosa < Anacadium occidentale < Terminalia catappa < Manihot exculenta < Impereta cylindrical < Chromolaena odorata < Manifera indica.

 

Key words: Air pollution tolerance indices (APTI), ascorbic acid (AA), total leaf chlorophyll (TCh), Abraka, Nigeria.
