River Pollution by Heavy Metal Waste

Rivers that become the pulse of life as a source for clean water needs of today's drastic decline in quality from upstream to downstream. The quality of the river decreased mainly by waste pollution is difficult to untangle. This can have a profound effect, for example, can poison drinking water sources, human poisoning, and the imbalance in the ecosystem of rivers and lakes.

The impact of heavy metal waste pollution in the river is very dangerous because it can not be destroyed and cause health effects is very dangerous to society. Heavy metals mercury waste is very toxic to life and disasters due to mercury pollution by the industry have occurred in Japan's Minamata Bay took hundreds of deaths and thousands of dead babies being born handicapped. The process of water treatment with alum is usually not able to remove heavy metals dissolved in water, so the content of mercury in the waters of fear it would contaminate the water taps citizens consumed. Heavy metals will contaminate fisheries and endanger public health is to eat fish.

The impact of heavy metals of lead that exceed the threshold in the child's body, can decrease the intellectual intelligence (IQ) and konsentrasi.Dalam higher concentrations, can cause anemia. Lead can stimulate the birth of a premature baby. Lead in the blood affect developmental disorders and behavioral deviations. Content of lead is highly toxic and can cause death in children. Lead can cause children more aggressive, lack of concentration, and even cause cancer.

Lead is absorbed by the child, although in small amounts, can cause interference with the early phases of physical and mental growth which then resulted in the function of intelligence and academic ability. Nervous and digestive systems are still in the stage of child development, and thus more vulnerable to lead absorbed. Lead can not be broken down biologically and toxicity did not change over time. Lead is inhaled or ingested will follow the flow of circulating blood, reabsorbed in the kidneys and brain, and stored in the bones and teeth.

Pollution of heavy metal waste in the river caused a very complex effects, which can give bad impact to the community. The government needs to act in dealing with pollution of the river as soon as possible so that not a lot of falling victim. Especially the handling of heavy metal waste that can cause death also resulted to the victim.
