Some fishes tend to have increased chances of bringing damages to our health. The reason for this is their elevated

concentrations of mercury.

Mercury is a heavy metal that is present among the naturally occurring elements. This element most times is found

in the earth’s crust as inorganic compounds such as mercury salts. They can also be found in the air and soil.

They also do occur as organic compounds of mercury like methylmercury which is formed when inorganic mercury

in the air combines with an organic molecule like carbon. It can also occur when such compounds attach to droplets

of water and enter soil, rivers, or oceans which are natural habitats to most fishes we eat from day today. Some

fishes that are at the top of the food chain in the aquatic habitat are prone to have increased levels of mercury in


Mercury intoxication can possibly occur when one consistently takes in foods that are contaminated such that it’

builds upon the body. The effects of this could include several conditions like kidney failure, reproductive disorders,

lung diseases, heart diseases.

Here are 3 fishes that are high in mercury concentrations that can incur these damages in our bodies.
