soil - is a unique and priceless natural wealth.That it is able to provide all the necessary human food resources.Ignorance and careless human activity - are the main causes of soil contamination.
Varieties of anthropogenic environmental degradation
Contamination of soil may be chemical or physical.Noise, vibration, electromagnetic field, ionizing radiation radioactive materials, thermal radiation - is the physical energy or pollution that arise due to anthropogenic activities.With each passing day increases the amount and variety of new industrial and transport enterprises, the chemical industry.Chemicals used in agriculture can lead to permanent anthropogenic environmental degradation.Causes of soil contamination - is various chemicals or xenobiotics that are received in the ground by means of gaseous, liquid and solid waste emissions.
main sources of soil pollution
Every year, the ecological situation in the country is deteriorating due to anthropogenic environmental degradation.Experts fix the crisis levels that are much higher than the permissible limits.A large number of businesses and factories emit gas, an aerosol and other harmful particulates.The scale of such pollution - regional and local.
Increasingly, cities and towns can be seen in the waters discharged liquid soluble and insoluble compounds.In addition to all the above emission into atmosphere pair mineral acids, organic solvents - all causes soil pollution.
environmental impact
important and necessary kind of a natural resource - it land.Every year there is a constant deterioration of the soil, depending on the natural and anthropogenic factors.Agriculture greatly affects the general condition of soil, causing erosion, pollution, depletion, acidification, alkalinization, waterlogging, degradation and gleying.
Environmental pollution of the soil - this is an important topic that is considered at meetings of scientists.It is well known that anthropogenic influences can affect absolutely all components of geosystems.The general state of soil cover negatively influences decrease in the area, which is occupied by natural vegetation formations.Man replaces it agrocenoses.Constant plowing can lead to the complete disappearance of vegetation, as well as changes in the components of the water balance.This process occurs because of the increase in the share of total runoff.Subsequently can significantly increase erosion, changes occur in the structure of the soil, and also impair its basic water and physical properties.Because of the heavy metals are suffering and all the vegetation.
Having a strong and constant wind, climatic conditions with insufficient moisture performance during the season, the destruction of natural vegetation due to extreme heat - it's all the environmental pollution of the soil.
consequences of oil pollution of land cover
When the soil comes petroleum hydrocarbons in the near future can be seen exclusively negative consequences.In areas where there is intense oil refining and oil production, physico-chemical properties of the earth rapidly transformed.
Regular oil pollution of soil can lead to the fact that the soil will shift toward the alkaline solution.Often there may be increased rates of total carbon.Do not forget about a significant change in the morphological properties of the earth, which is to strengthen kutanoobrazovaniya.After it may be a change of color characteristics of the soil profile, as well as the deterioration of the formation of any vegetation.
experts and scientists were able to prove that the contamination of soil with oil - it is a strong and critical impact on the natural resource represented.To then return it in good condition, it may take more than a decade.
Soil chemicals
In today's rapidly evolving large manmade intensification, which is by all means contributes to pollution and dehumification land.At the same time there is a secondary salinization, as well as a variety of soil erosion.
The land cover contains metals and pesticides, but because of mismanagement and careless handling of its concentration of these substances may increase several times.Soil contamination by chemicals include vehicle exhaust emissions, making compost fertilizer and much more.Because of contact with soil chemical indicators natural metals such as lead, mercury, cadmium and copper, increases several times.
Experts recommend the use of pest control only natural, natural and biological methods.These include genetic methods natural chemical compounds.Only in full compliance with all the rules of soil contamination by chemicals will not occur.This must be taken into consideration!
Anthropogenic soil contamination
anthropogenic sources of land degradation are stationary and non-stationary objects.It is worth noting here that include industrial and agriculture.Scientists have determined that the economic, domestic and energy facilities in most cases are man-made sources.
When viewed from the perspective of the scale of the impact on the environment and the earth, the anthropogenic pollution of the soil can be divided into global, regional and local.Mobile vehicles that leave behind a large amount of exhaust gas, which may affect the general condition of the soil cover.
Effect of pesticides on the ground in the modern world
Pesticides are largely exclusively organic compounds.They have low molecular weights and different solubility characteristics in water.In today's world, the soil is the successor to pesticides that degrade it.There may be provided by the movement of substances in the plant or the environment.
Soil pollution by pesticides occurs when the ground has got a large number of organic compounds.It can lie in it for a long time after application.It is worth noting that the pesticide may include a whole range of different chemicals, which are designed to deal with animals and plants.
As you can see, the causes of pollution of the soil can be varied.Some people do not even realize that their usual activities sometimes adversely affect such valuable resources such as land.
