High levels of mercury contamination have entered the aquatic ecosystem primarily through:

a. Medications like vaccines which contain mercury and subsequently enter the drainage systems through human waste.

b. Paper productions which uses mercury in a bleaching process to whiten the paper.

c. Emissions from coal burning power plants which then rain down on waterways.

d. Merurcury solutions which are used in plastic production and then disposed of through waste water.

Answer: Option C.

Emissions from coal burning plants which then rain down on water ways.

Explanation:

Mercury has been found to be most serious and most common water contaminants. Mercury causes water pollution. It is released into the air and falls back in water ways. When it's get to water ways, bacteria changes it to methylmercury, if absorbed by aquatic organisms destroyed them. When consume by humans, it causes neurological disorder and kidney problem. The two major sources of Mercury contaminants in water ways are emissions from burning of coal plants and waste incinerators.
