Contamination of water

Bringing our grain of sand to the matter, we have prepared a brief overview of what trafficking theme, towards understanding the different problems and forms of pollution that now day are detected, and to understand better why are certain preventive measures.

There are two ways of induction of water pollution, a shaped direct (in contact with the contaminant, intentionally) either in the form hint (the intention is not to dump the pollutant in water, but that it comes in contact through another medium)
The causes are then divided into two basic types:


Natural pollution: Water cycle, and includes the addition of minerals and organic waste taking contact with water, eliminating its purity and requiring a start treatment to be consumed by humans. 

Pollution Antrópica: as its name indicates, the source of pollution is the actions of man, with origins that are completely different (and in fact, on a daily basis are often discover more ways to damage the quality of the water) ranging from the use of pesticides, until discharged fuel both by boats as accidents in oil deposits.

As we have said, is a necessary good for life, by which the main consequence of the contamination of water is logically the damage to the many species that inhabit an aquatic ecosystem, by altering their living conditions and can even cause death.

The intake of water in poor condition or that it has been improperly treated can cause a large number of disorders to health, as well as alter the conditions of life of the surrounding areas and affect the economic activities that depend upon it.

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)

Contamination with metals

It's pollution by Toxic metal, being primarily that they hardly occur in gaseous form, with the exception of mercury and selenium, for which his appearance outside the area where there is a deposit of them, is merely caused by human activities.





There are various avenues of access and deposit of a natural resource metals, subsequently causing entering metabolism and subsequent poisoning of living beings, so then let a picture that will be very useful to quickly understand the process:


On the other hand, there are two variables which facilitate its spread:
Bio-concentration: the toxic metal in living beings are concentrated in tissues and organs through biological mechanisms, causing a subsequent intake of these cause acute intoxication.

This is the case of shellfish, for example, that filtered the water where they mobilize and retain arsenic, causing a further concentration of the same.Bio-magnification:This concentration is higher in higher species on the food chain, which in the primaries.



Toxic action of the Toxic metal has variation according to various factors present in the individual affected, as the following, among others:

Environmental Contamination Poisoned Air

Until the industrial revolution, the purity of the single atmosphere was altered by natural causes, such as for example the volcanic eruptions, but currently, the activity of man is to the atmosphere as a huge volcano not to introduce new substances in the air, making not only pollution but other dangerous evils as the rain.



Also, there is a big difference between gas eruptions and the chimneys and exhaust pipes. The latter release substances often strange, which react between if and natural atmospheric components, causing this, serious disturbances.
The massive introduction of pollutants alter the composition of the atmosphere and seriously damages human health , climate stability, and development of ecosystems, causing damage to the planet that are much more than a generation or a hundred years.
