Abstract
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.
