Both Cadmium and Nickel are of great environmental concern; Cd is on the
EPA Priority Pollutant list, as is Ni. Both have well-documented toxic
effects on various organisms. 

Lithium is fairly abundant (app 30 ppm in the Earth's crust), but I can not 
find or remember any EPA or state regulations on its release. *Airborne*
concentrations of 5mg/M3 can cause lung irritation.

The analytical menu for one full-service local lab doesn't even list
Lithium as an available test.

Theraputic use of Li for treatment of manic-depression (I don't have the
dosages) can have neurological and renal consequences.

I've read a *lot* of papers on metals in marine and aquatic environments,
and can't recall Li being a subject of such research, but I never looked
for Li specifically.
