Bioremediation of textile effluent polluted soil using kenaf (Hibiscus cannabinus Linn.) and composted market waste

BS Bada


This study determined the performance and heavy metals uptake of kenaf at different levels of compost application in textile effluent polluted soil. Polluted soil was collected from the vicinity of a textile company in Nigeria. Twelve-litre plastic pots were filled with 10 kg soil. Soil amendments applied were: 0 (control), 60 Kg N ha-1 of N.P.K 20:10:10 (recommended rate), 40, 60, 80, and 100 Kg N ha-1 of Composted Market Waste (CMW). The pots were arranged in Completely Randomized Design and replicated three times. Growth parameters were taken. Plants were harvested 8 weeks after sowing and separated into leaves, stems and roots. Lead, Cadmium, Chromium and Zinc levels in plants and soil were determined using Atomic Absorption Spectrophotometer. Data were analysed using descriptive statistics and analysis of variance. CMW at 100 Kg N ha-1 significantly (p < 0.05) enhanced the growth and yield of kenaf. Highest concentrations of heavy metals were observed in kenaf parts at 100 Kg N ha-1 of CMW. Higher concentrations of Chromium (0.15 mg kg-1) Lead (1.50 mg kg-1) and Cadmium (0.14 mg kg-1) were observed in the root while higher concentration of Zinc (23.48 mg kg-1) was observed in the leaf.
