I would rather know what the risks are than remain in the dark. This is the first stage in establishing a toxic effect but without more research the information is very limited and that is the real problem.

100% agree, that's why its so important to do the research.

It may also be that avoiding certain practices like putting boiling water in plastic bottles virtually eliminates the risk.

Yep! We certainly don't know what the best practices for things are, unless we research the compounds thoroughly and actually understand their properties as best we can.
