Since APs and APEOs are non-biodegradable, they cause severe environmental problems when they are released
to the environment as discharges or emissions. They are potent endocrine disrupters to the aquatic environment
and can cause feminisation in male fish. As a result, the fertility or reproductive capability of the fish is reduced
