No clear answer, but two suggestions:

1) You should be able to find out toxicity info from the product's MSDS (Material Safety Data Sheet) which can be searched for on-line (although I don't know how without using my company's private resources, but if I needed one I'd try Googling) or should be available from the glue's supplier (any business buying that glue needs access to the MSDS).

2) Any possible problems would be reduced by letting the glue cure and outgas for a lengthy period before putting it in the pond (the less glue smell you notice, the more it has already outgassed).
