Contamination of soil

Then has rowing a brief overview of what is about this theme, and the key elements in order to understand not only why are applied measures of protection and sanitation, but also the consequences of not complying with them reliably.

There are two fundamental types which in generated thus detrimental to our support no matter the damage caused by each component or its physico-chemical properties, they are generally classified according to their origin:

Natural contamination: attributed to phenomena relating to the structure of the same or endogenous factors, natural. For example, is caused by the eruption of a volcano, which has been found to cause the same pollutant factor that several power plants that consume fossil fuels to operate at the same time. Pollution from human activities: in this case, the contamination of soil is purely and exclusively by the intervention of man, using pesticides in agriculture, through the lack of control and the underground tanksruptures, or landfill in poor condition or that they have not been verified, among other causes.

There are a myriad of damages caused by the bad state of the soil or lack of control over it, among which there is a great risk to human health, either directly to the contact with the toxic, or indirectly, where the same transport affects a tributary of drinking water or vegetable consumption.

When the permissible level of pollutants exceeds the tolerable, and will reach a critical level, it seriously affects the balance of the ground, with the presence of toxic substances for all organisms that live there, and causing a gradual loss of soil productivity (i.e., the ability to host life, necessary for the you planting and harvest)
