Rubbermaid vs. the real deal

Hello All from a first time postee,

I am making my first foray into ponding. I'm familiar with the products and
techniques, but have never actually used them. To practice, I've bought a
large Rubbermaid type storage bin from Wal-Mart which I intend to disguise
well and stock with literally one or two small mosquito fish or tadpoles
from a nearby pond.

My question: Does that type of plastic emit any dangerous chemicals or
gases into the water that would poison flora or fauna? I'm not looking for
long-term quality, just short term practice.

Thanks.
