Now read the text carefully to find out what mercury really is
1. Mercury enters the environment as the result of the normal breakdown of minerals
in rocks and soil from exposure to wind and water, and from volcanic activity. par. 1 2. Human activities since the start of the industrial age have resulted in additional release of mercury to the environment. par. 1 3. Estimates of the total annual mercury releases that result from human activities range from one-third to two-thirds of the total mercury releases. par. 1 4. The levels of mercury in the atmosphere are very, very low and do not pose a health risk; however, the steady release of mercury has resulted in current levels that are three to six times higher than the estimated levels in the preindustrial era atmosphere. par. 1 English for Biology Teachers PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI5. Approximately 80 of the mercury released from human activities is elemental
mercury released to the air, primarily from fossil fuel combustion, mining, and smelting, and from solid waste incineration. par.2 6. About 15 of the total is released to the soil from fertilizers, fungicides, and municipal solid waste. par. 2 7. With the exception of mercury ore deposits, the amount of mercury that naturally exists in any one place is usually very low. par. 3 8. As a result, the larger and older fish living in contaminated waters build up the highest amounts of methylmercury in their bodies. par. 6 impure yearly polluted natural firm common supplementary essential fundamental little recent hard5.
