This implies waste with low leachability.

These tests confirmed that EMC made from fly ash "showed a low surface specific leachability" with respect to "all environmentally relevant metals."

Further, leachability tests were performed by LTU in 2001 in Sweden, according to normative standard NEN 7345:1995, on behalf of a Swedish power production company.

This is primarily due to the toxicity of lead, and the amount of lead that leaches from printed wiring board assemblies, as determined by the leachability study conducted by the partnership.
