    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

    Morphological responses of Anacardium occidentale L. (Anacardiaceae) to lead (Pb). International Journal of Phytofuels and Allied Sciences
    (Society for the Conservation of Phytofuels and Sciences, 2020) AbdulRahaman, AA; Sagaya, A; Sholarin, AA; Adeniran, SA; Al Sahli, AA; Alaraidh, IA
    Cashew plant (Anacardium occidentale L.) seeds were pretreated with concentrated tetraoxosulphate (IV) acid (H2SO4) in three concentrations: 5%, 10% and 20% in 5, 15 and 30 minutes each and were grown in lead (Pb) (Lead (II) acetate) Pb(C2H3O2)2 contaminated soil (7 kg) in three concentrations 1000 ppm, 3000 ppm and 5000 ppm. Seed emergence was appreciated in 5% acid concentration and depressed in 10% and 20%. However, the effect of Pb was significantly observed as it delayed seed emergence in the control plants. Plant height, number of leaves and stem girth increased significantly across the months while the leaf area was depressed. The total Pb content was determined using Atomic Adsorption Spectrophotometry (AAS). The present result showed higher root Pb compared to shoot Pb, indicating limited mobility, once absorbed by the roots and that its accumulation and translocation is concentration dependent in relation to the pretreatment time interval. The result showed that the plant demonstrated a physiological response to Pb pollution, which suggests that cashew plants are indicators of heavy metal accumulation and the effect on the environment.
