Nickel hydride decomposes to spongy nickel metal, which is surprisingly toxic. At our work, we use nickel powder, and it is regulated and listed as severely as any other heavy metal. It's listed as a carcinogen.

I'd guess that as a disposal hazard, nickel and lead-acid batteries run about even. Where nickel batteries come out ahead are higher energy density and a much more tolerant disposition toward multiple deep discharges.
