Trace Metal Accumulation and Phytoremediation Potential of Four Crop Plants Cultivated on Pure Sewage Sludge

Phytoremediation is a viable strategy to remove trace metal contaminants from sewage sludge but still poorly investigated. The aim of this study was quantify the removal B. napus, juncea, H. annuus, Z. mays grown on pure sludge. Each species six different for 8 weeks and were analysed content physico-chemical characteristics. Our results confirmed that all tested supported plant growth. showed vigorousness lower (46% sludge) or similar/increased (54% compared control treatment. juncea napus most efficient in bioaccumulation, metals. average percentage metals removed by selected 0.2% As, 0.85% Cd, 0.09% Cr, 0.36% Cu, Ni, 4.2% Se, 1.2% Zn. In conclusion, our phytoremediation can be applied sludge, despite chosen have low efficiency element removal. Further studies using hyperaccumulator are needed which may lead higher process opening up new possibilities management strategies waste.
