Eutrophication and brownification change phytoplankton community structure and decrease the production of essential omega-3 fatty acids in lakes.

An adverse outcome pathway, or AOP, is a highly structured way of describing a toxicological process which can lead to an adverse health effect in humans or wildlife, caused by an unsafe exposure to a chemical substance.
