Hi,
Euthrophication occurs in water bodies such as rivers, lakes and ponds. It results in smelly water bodies which have bacteria growing in large numbers in it and it is devoid of fish, and other aquatic animals and also submerged plants such as hydrilla.
Excess fertiliser usage by farmers and runoff from animal farms and raw sewage from human settlements cause euthrophication.
Respect for ecological systems is of utmost importance in us leading eco-sensitive lifestyles.

Hi,
Minamata disease is caused by mercury poisoning. It occurred in Japan in 1952 to 1960.
In 1952, a company involved in making plastic products dumped its waste water into the Minamata River. Buy the time they were stopped in 1966, 400 tons of mercury was was dumped.
Minamata disease caused nerve problem and involuntary nervous twitches and loss of balance when walking. Severe birth defects was seen in children born to mothers who consumed tainted fish and other seafood from the region. Even small amounts bio-non degradable substances get concentrated into lethal concentrations due to bioaccumulation.
Cheers
