Introduction

Sobat Penurut, mercury is a naturally occurring element that can be found in the air, water, and soil.

What is Mercury?

Mercury is a heavy metal that is liquid at room temperature. It is a naturally occurring element that can be found in the earth’s crust. Mercury is used in many industrial processes, including the production of chlorine and fluorescent light bulbs. When released into the environment, mercury can enter the air, water, and soil.

How Does Mercury Get Into Fish?

Mercury can enter the waterways through natural processes such as volcanic eruptions and erosion. However, human activities such as coal-fired power plants and industrial processes have also contributed to the increase in mercury levels in the environment. Once in the water, mercury can be converted to methylmercury by bacteria. Methylmercury is a highly toxic form of mercury that can accumulate in fish and other seafood.

What Types of Fish Have High Levels of Mercury?
