Default Treated wood

I looked into this a few years ago and after extensive reading. I have concluded.
1. even if using older treaded lumber Arsenic is not take up by plant roots.
2. I would be very careful not to breath the saw dust and remove any generated during building. Arsenic and copper sulfate and the other verious form of copper they tread wood with are not good for you.
3. Untread lumber is cheaper and if paint with tung oil (or paint which is more expensive) it last a long time. Seven years to date and holding the beds in place with little sign of decay. (And that is in the hot sometimes wet south)
