Acidic and near-neutral washing solutions reduced the soil As level by 32–62%.
- class="label">•
The (NH4)2SO4−, NH4H2PO4−, (NH4)2C2O4-extractable As were greatly reduced.

But seed germination, growth, and enzyme activities were lower in the washed soils.
- class="label">•
Greater toxic effects are largely due to changes in soil properties after washing.

Proper post-treatment techniques need to be selected for reuses of the washed soils.
