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.
