- •
Effect of amendments on immobilization of HMs and plant uptake was studied.
- •
CaO, FA, sulfur and Na2S reduced the DTPA-extractable Cd, Cu, and Pb in soil.
- •
The amendments have increased the solubility of Cd, Cu, and Pb in soil system.
- •
Shoots of Chinese cabbage accumulated more Cd, Cu, and Pb compared to roots.
- •
Sulfur reduced soil pH (3.6) and did not support the growth of Chinese cabbage.
