what is the difference between biomagnification and eutrophication?
Biomagnification is also called Bioamplification. It is simply the increase in concentration of a substance in a food chain, not an organism. Persistent organic pollutants (POPs) are compounds that biomagnify. Persistent organic pollutants (POPs) are chemical substances that persist in the environment. These substances bioaccumulate through the food web and pose risk not only to humans but also other living organisms because of their adverse effects. These pollutants consists of pesticides (such as DDT), industrial chemicals (such as polychlorinated biphenyls, PCBs) and unintentional by-products of industrial processes (such as dioxins and furans). The over-enrichment of water by nutrients such as nitrogen and phosphorus—is a leading threat to water quality around the world. Also known as “nutrient pollution,” eutrophication upsets the natural balance of aquatic ecosystems, which can lead to algal blooms, red tides, hypoxic or “dead” zones, fish kills, and, eventually, ecosystem collapse.
