Effect of air pollution on the foliar morphology of some species in the family Euphorbiaceae in southwestern Nigeria

Abstract

Morphological studies of the leaves of ten species in the family Euphorbiaceae collected from three different locations with different pollution levels in Southwestern Nigeria were carried out in order to establish the effect of air pollution on these species The study was carried out in both dry and wet seasons Climatic data and pollutants concentration levels of the study sites were determined Leaf area of all the species was measured using an established nondestructive method while petiole length was determined using metric ruler The result showed that most species showed significant reductions (p
