Answer Text:
Pollution effects of soapless detergents.
1. The active ingredients such as alkylbenzene sulphonates are nonbiodegradable, hence accumulate in water sources and end up in human bodies.
2. Some of the additives such as phosphates cause eutrophication hence excessive build up of algae (algal blooms) which change the water taste and odour, and also reduce oxygen supply hence poor growth of aquatic organisms.
3. Because of their high lathering tendency, they cause excessive frothing and foaming in water sources especially after heavy rains.
