In recent years significantly increased the impact of man on nature, so there was a threat of depletion of certain resources.In addition, the increased scale of emission of waste in nature.It touched the soil, which are an essential component of the biosphere, and determine many of the processes occurring in it.This soil cover is the basis for human settlements, and therefore the consequences of soil contamination is necessary to prevent as much as possible.
soil and its importance in human life
This natural formation of great importance to humans.In the first place as a source of food.In addition, the soil cover is involved in creating a positive environment for optimal living, leisure and working people.
Thanks land resources of the planet to provide necessary food can be a population much larger in number than now live on Earth.Also, the soil is a regulator of the chemical composition of the hydrosphere, the atmosphere.
Types of soil contamination
consequences of soil contamination can be minimized, but it must be nice to know what types and sources exist.
main pollutants of soil cover are: fertilizers, pesticides (pesticides), flue gas emissions, waste products, oil and oil products.
Pesticides - are chemicals widely used in agriculture to control weeds and pests.Accumulate in the soil, they can be passed along the food chain and cause serious diseases in humans and animals.In a world of constantly increasing the production of pesticides, which is extremely negative impact on health.
Chemical fertilizers can also cause soil pollution and its effects.This happens as a result of their use of unreasonable quantities, with losses in the production or transportation.
waste and industrial waste also lead to an intense contamination of soils.Considerable areas of land occupied by landfills, many of whom are toxic.
enormous harm to the normal functioning of soil applied flue gas emissions.Industrial enterprises emit pollutants (heavy metals), especially dangerous for people who are able to accumulate soil.
a result of imperfections in the technology of oil production one of the most pressing environmental problems in our country is the pollution of the upper layers of the lithosphere of oil and its products.
extent of the problem in our age of scientific and technological breakthrough greatly increased the negative impact of man on nature in general and especially in the upper layer of the lithosphere.From human intervention a change in the soil, the nature of the land.
main impacts on soil are as follows:
- erosion;
- desertification;
- swamping;
- pollution.
Lately particularly acute problem of pollution of the lithosphere, in particular, should pay attention to issues such as the sources of pollution of the soil, the effects of pollution and solutions.
sources
main factors causing pollution of the soil, the following:
- domestic enterprises and residential buildings (food waste, household garbage, feces, garbage-governmental organizations);
- agriculture (pesticides, fertilizers);
- industry (heavy metals);
- transport (exhaust gases deposited on the soil surface).
Consequences
Pollution considered getting into it various kinds of waste, toxic substances, chemicals that lead to the inevitable result.The effects of soil contamination is inevitable and include: changes in the terrain, its structure, subsidence and displacement of rocks, intensification of hazardous geological processes.All this is extremely negative impact on the activity of microorganisms in ground cover, fertility.Is the destruction of the ecosystem.The negative effects of pollution of the lithosphere, undoubtedly, affect the health of the population and that with each generation still deteriorating.
workarounds
important role in the recovery of soils can play greenery.If along the motorway to create a continuous green strip of hawthorn or maple, a significant portion of the exhaust gas is absorbed by them.The most contaminated areas may also be set aside for afforestation.
consequences of soil contamination can be reduced if you start to recycle waste.It is worth to do land reclamation, to introduce a clear control over the use of mineral fertilizers.Contamination by pesticides can be reduced by improving the composition and prevent accumulations in the soil cover.As an alternative to pesticides is likely to use insect predators, the so-called biological protection (this is the ants, ground beetles, ladybugs).For the construction is necessary to take the land unsuitable for agriculture.It is also possible to carry out the removal of need from the soil oil.
enormous natural wealth is the population of the Earth.This soil.Causes, effects of soil contamination remains today one of the most pressing issues that need to closely engage experts.At the moment, the problem - one of the major problems of mankind.It can be solved only if you approach the issue comprehensively, without losing detail and without making concessions.
