文摘
- •
Limestone treatment was partially effective for reducing trace metal concentrations.
- •
The initial pH (< 3) increased to 4.5–5 ten years after addition of limestone, and was stable after then.
- •
The neutralization capacity of limestone added to Young Dong AMD in Gangneung, Korea, was limited.
- •
Redox, dilution on mixing, and co-precipitation/adsorption controlled the spatial and temporal distribution of elements.
