Hi Everybody,

I'm doing a little background work on my niece's proposed science fair
project - that is, checking the safety issues of the supplies she's
requested. I thought you all might be able to help me out on this:

She needs a small amount of nickel powder or nickel shot to mix with soil
in which she will be growing plants.

Sites like the Los Alamos Periodic Table say:
Nickel is recognized as being potentially carcinogenic.
"Exposure to nickel metal and soluble compounds (as Ni) should not exceed
0.05 mg/cm3 (8-hour time-weighted average - 40-hour work week)."

Yet, k-12 science suppliers sell nickel shot and powder, and label it
non-hazardous.

Does anybody know, is handling nickel powder or shot dangerous? What are
the dangers here?

Thanks for any advice you can send my way - it will help me earn my
good-aunt merit badge!

Kelly
