3.3 Heavy metal contents in sugarcane and sorghum
Significant contents of Cr, Cu and Pb were observed in sugarcane and sorghum plants in the present study (Figure 2).
The Cr, Cu, Cd and Pb contents in sugarcane ranged from 4.338 – 8.667 mg/kg, 6.65 – 20.007 mg/kg, below detectable limit (BDL) – 0.71 mg/kg and 1.908 – 3.157 mg/kg respectively.
But the highest levels of Cr (14.334 mg/kg), Cu (29.334 mg/kg), Cd (0.971 mg/kg), and Pb (7.33 mg/kg) were found in sorghum.
