Dampak and Solutions of Soil Pollution
A.Impact of Soil Pollution
Berbagai impact caused by soil pollution are:
 1.The impact of soil pollution caused by waste from limbahdomestik:
-can cause odor and an eyesore.
-scum covering the surface of the soil so that the soil becomes bisadimanfaatkan.
-Heaps of garbage can produce nitrogen gas and acid sulfide and zatmercury, chromium and arsenic that causes disruption of the bio soil, vegetation, damage soil structure and texture of the surface.
-Limbah such as metal oxides can not be dissolved maupunyang larutmenjadi toxins at ground level.
-Inorganic waste which is not too
-Biodegradation
tidakdapat causing soil penetrated by plant roots and is impermeable to water so that the water infiltration that can enrich the soil danmineral lost and the number of microorganisms in dalamtanahpun will be reduced as a result of plant is difficult to grow even die due to food tidakmemperoleh berkembang.
2.The impact of soil contamination caused by wastewater:
-Limbah liquid form of feces, detergents, used motor oil, paint, etc., when absorbed into the soil will damage the soil water content and the amount of chemicals in it to kill microorganisms in the soil.
-Limbah liquid metal plating industry waste products containing substances sepertitembaga, lead, silver, chromium, arsenic and boron are substances that are beracunterhadap microorganisms. If soak into the ground will mengakibatkankematian for microorganisms that have an important function terhadapkesuburan ground.

3.The impact of soil pollution caused by solid waste: solid waste landfill industrial waste product resulting pembusukanyang cause odors around because there is a chemical reaction that menghasilan gastertentu and in the long term can damage danmengkotaminasi surface water seep into the ground with a certain bacteria that kualitasair soil dry season becomes menurun.
4.The impact of soil contamination caused by agricultural activities:
-Agricultural activities that use fertilizer will constantly undermine strukturtanah causing reduced soil fertility and can not be planted because jenistanaman certain nutrients in the soil decreases.
-Farming that uses pesticides can kill mikroorganismeyang sehingg useful in the soil becomes fertile soil.
5.The impact of soil pollution on health:
Berbagai kinds of chemicals that pollute the soil can cause a variety of health macamgangguan, for example:
-Chromium, pesticides, and herbicides is a material that is karsinogeniksehingga can cause cancer.
-Lead can cause brain damage in children and kidney damage padaseluruh population.
-Benzena can increase the chances of developing leukemia if exposed continuously at a certain concentration.
-Mercury (mercury) and can cause kidney damage siklodiena bahkansampai untreatable.
-PCBand siklodiena can cause liver toxicity.
-Organofosfat and karmabat can cause neuromuscular disorders.
-Solvents containing chlorine can stimulate a change of heart and kidney sertadapat lower pusat.6 nervous system.

The impact of soil contamination tehadap ecosystems: soil pollution can impact on the ecosystem, for example:
-Changes in soil chemical radicals arising from the substance or dangerous kimiaberacun can cause changes in the metabolism ofendemic microorganisms and arthropods that live in the soil environment yangtercemar.
-Destroying some primary species and the food chain to large memberiakibat against predators or other levels in the food chain.
-Impacts on agriculture which causes metabolismetanaman changes can have an impact on the conservation of plants continued dimanatanaman not able to hold the soil from erosion.
B.Solution of Soil Pollution
To overcome the problem of soil pollution is needed a solution daridampak soil contamination. The solution is used to solve the problem polusitanah by source:
1.Soil contamination by heavy metals (Hg (mercury), cadmium, tin, lead, copper, nickel, zinc, chromium, and manganese) can be overcome by adanyaa.

Remediation remidiasai tradisionalDalam traditionally used three ways: through treatment suhutinggi, agents compression and washing process. The high temperatures used untukmenghasilkan compound granular shaped glass similar to the nature of tidakdapat dilumerkan by rain. Agent compression function untukmenghasilkan compound similar to cement. Untukmencuci washing and cleaning process contaminants are discharged to a shelter (Mustaqim, 2010).
B.Land management tercemarMenurut USDA (United States Department of Agriculture) tanahtercemar management can be done by the following:

Raise the soil pH above 6.5 or higher
Logam cation will dissolve in acidic conditions.
Oleh therefore, menaikkanpH soil can reduce the risk of transfer of heavy metals into dalam tanaman, so the consumption of animals to heavy metals can dikurangi.Menaikkan pH has the opposite effect on the heavy metal cations adadalam shape. This causes the need to study the conditions yangkomprehensif suspected contaminated soil heavy metals.
