Abstract
Environmental pollution from food or related industries via effluent discharge is a global threat
to plants and animals and may ultimately threaten the quality of human. The present study aimed
at evaluating the dangerous effect of industrial effluent on the toxicity and morpho-anatomical
deformations of Corchorus olitorius and Senna occidentalis. The study was a split plot complete
randomized design with two factors, each comprising of four treatments and three replicates
which lasted for a period of three month. Treatment details include T0 = Tap water (control), T1=
25% pollutant + 75% tap water, T2= 50% pollutant + 50% tap water, T3= 75% pollutant + 25%
tap water, T4= 100% pollutant. The result showed that a significant concentration of nickel,
copper, lead, cadmium, chromium and iron were detected in the pharmaceutical effluent while
copper, lead, cadmium, chromium, iron and mercury were detected in the soap and detergents
effluent. A significant inhibition was observed at 100% concentration of the seedling growth
parameters (stem length, leaf size, number of leaves and root length) in both Corchorus olitorius
and Senna occidentalis while a significant reduction in leaf size was observed with increasing
concentration of the industrial effluents. Anatomically, there was no difference in the epidermal
cell size and the effluents increased some stomatal parameters such as stomatal density at 25%
and 50% concentrations and decrease from 75% and 100% effluent concentration. It also
increases the stomatal index and size at high or low concentrations. This study has shown that
the two industrial effluents contained some harmful pollutants which are dangerous to life of the
plants, adversely affected germination, growth and development at higher concentrations than
lower concetrations, they also modified several anatomical structure in the leaf epidermis of
Corchorus olitorius and Senna occidentalis
