文摘

Reused approaches resulted in reduced concentrations of metals in leachates. TUs of sludge leachates are still greater than 1.0 after being reused. Cr and Ni contributed most to the total toxicity followed by Zn and Cu. Making sludge into bricks reduced more toxicity than landfills. Combining bioassays and instrumental analysis make better evaluation of sludge.
