Avicennia marina Plants Sea Pollution As The Neutralizing

In general, pollution is defined as the process went or the inclusion of living things, matter, energy or other component into an environment (water, soil, air) and / or changes in the quality of the environment by human activities or natural processes so that quality is going down to a certain point which causes environment becomes less or is unable to function as intended. At the present time the Indonesian sea conditions are very poor. High marine pollution due to the destruction of coral fish bombs, made a number of marine biota including fish, the more difficult to breed.

More marine pollution caused by dumping industrial waste into the river which empties into the sea. Heavy metals from industrial waste, speed up the process of decomposition in marine catches, by making the fish have a low acid so as to maintain the freshness of the fish is done by using formalin. The types of heavy metal often found in marine biota of the body such as Ag, Hg, Cu, and Pb. Heavy metals is an essential element for living organisms but if the amount exceeds the threshold can be toxic.

Sources of heavy metals that pollute the ocean waters are generally derived from natural or artificial sources. Natural sources such as heavy metals come from: 

1. Local rivers and the beach erosion caused by wave activity. 
2. Enter the deep ocean covering the metals are released by volcanic activity in the sea and the metals are released from particles / sediments from chemical processes. 
3. Input from the environment near the coast, including metals transported fish from the atmosphere as dust particles. While the source of heavy metals originating from man-made such as heavy metals are released by industrial processes metals, liquid organic fertilizer processing, paper industry and other industries.
