algcides and environment

anyone here know how does algicides, flocculants , polyquat n oxidisers affect the environment?all the above kills algae but wat r the consequenses 2 the environment?

It depends on factors such as the ingredients of the particular algaecide, the concentration of those chemicals present in the environment, and the type of ecosystem that is contaminated by it.

In general, releasing large quantities of any poison into the environment tends to kill not only its usual target (algae) but also adversely affects other species as well (whether through direct exposure or via bioaccumulation).

The manufacturors of the algaecide will probably tell you that it's safe if used properly (i.e., not too high a dose which will eventually breakdown before causing harm). But that's often questionable.
