Background: This study was carried out in order to evaluate the pollution potential and chemical interaction levels of PBDEs congeners in relation to positive or negative reactions in soil and bitter leaf around e-waste dump site.

Method: The soil and plant samples around e-waste dumpsite were evaluated via integration after ultrasonic extraction with the use of ultra-sonication and the quantification of the individual persistent organic pollutants, for each sample with the aid of gas chromatography. The statistical analysis was conducted using window 10 version Microsoft.

Result: The results showed that positive pollution potential were high up to 5.250 at depth 20 – 30 cm (BDE- 25). Below detectable pollution potential and chemical interaction was detected for soil, leaf and root across months. The total BDE congeners for studied soil ranged from 29.84 – 3,049.34 ng/g and that for control and impacted plant ranged from 12.48 – 99.21 ng/g. The concentration of PBDEs across depth showed no definite trends, but there was a significant difference when the control and studied soil were compared. The pollution potential and chemical interaction of control and plant around e-waste showed no remarkable difference.  The positive pollution potential and chemical interaction were dominated at the lower polybrominated diphenyl ethers congener than the higher congeners.
