"Formaldehyde is a ubiquitous, naturally occurring substance produced by every living organism. Studies show that formaldehyde is readily biodegradable and does not accumulate in either the environment or in people. In the environment, formaldehyde is quickly broken down in the air by sunlight or by bacteria in soil or water."
The above is accurate, but the problem is that it does not take a very high concentration of it to make it very toxic to all biological processes. This is what makes it effective as a black tank odor control. By killing the biological activity, the formation of sewer gasses is stopped. The problem with using it in an RV is that if the black tank gets dumped into an anaerobic treatment system that counts on the activity of an bacteria colony, it can easily damage or kill off the colony. Then the system will fail in short order. If you are always going to dump into a municipal system, it is not an issue as they always use aerobic processes.
