III. Measures for improvement and minimize soil pollution.Once the land has been polluted will have extremely great harm to human lives as well as the creatures, so the need to land pollution prevention in a positive way. Want to do that, we need to implement the following measures: General-Processing methods in place:+ Evaporation method: near chemical plants and industrial zones, dong strong deposition of air pollutants are in the ground, absorbed by the charcoal.+ Processing methods using plants: sunflowers to absorb uranium, several types of ferns absorb arsenic, many of the trees and the mountains of the strong absorption of zinc, lead absorption, mustard tree clover absorbs oil, ....+ Pickled method extraction: active substance combined with the surface to soak and extraction of substances from pollution gay collectors extracts by gathering and storage systems.+ Fixed method of pollution by electric current+ passive processing method: use the process occurs naturally as the volatility process, ventilation, biodegradable, biodegradable by light to decompose the polluting the chat.-Contaminated soil treatment after peeling off from the position+ Phấp by ground processing Methods: sprayed on a surface of the ground to decompose the contaminants by using biodegradable processes, biodegradable by light happens in a natural way.+ Heat method.+ Method mixed with the bitumen asphalt.+ The close method block.+ Peeling method and buried.-Investigation and analysis of soil: soil pollution investigation is to find out the status of pollution and assess the extent of pollution. Now get the "basic values" as the standard of review. Based on the mean concentrations of toxic elements or compounds in the soil exceeds the "basic value" to evaluation.-Eliminate sources of pollution: in garment factories, plants, mines should study the cleanest, not production or at least produce toxins. The waste types should be how to handle the recovery. Currently, soil pollution is mainly derived from the plant and the water drain, so the city at watering for plants need to be careful.Need to select the user type high effect agri but less toxic, less viable in the soil. Remove completely the cosmetics have banned its use. A new direction restricting the use of drugs that cause pollution is need expand methods of creatures in the room except in combination with other methods (except synthetic)-Clean the fields chemistry: Use of lime and salt to sour alkali phosphates, transferred the majority of metal elements to the insoluble compounds from which reduces its concentration in the solution.Drainage depressions, regulate land Eh makes some heavy metal elements move to form insoluble.Rotational color rice to decompose DDTImprovement of motor components, enhanced soil organic fertilizingFor sandy soils should enhance the buffer and the capability to adsorption of metal cations and non-pharmaceutical, agricultural and general practices enhance soil fertility, create conditions for active organisms decompose the agrichemical exists in the soil-The use of the information system of gathering, sorting, garbage disposal, Thai-Limiting the use of chemical fertilizers, plant protection drugs, use fertilizer properly+ Manure according to the results of environmental analysis + Using appropriate crop varieties+ Balance fertilizing (N:P: K and organic) + The number of suitable fertilizer, especially nitrogen + The appropriate water management-The plants are built high chimneys to take up higher emissions, must have waste treatment systems, to save but still ensure quality waste processing, can build waste treatment system focus.-Propaganda of environmental protection-Implementation of environmental law.First of all need to educate people in the implementation of environmental protection in General and soil environment in particular. With regard to the violation of environmental law unit, the need to handle tough Proposed 184 (PENAL CODE). The crime of causing soil contamination+ People buried or waste into the soil toxic substances too standard, has sanctioned the Administration that deliberately not implementing the remedy according to the decision of the Agencyhas the authority to cause serious consequences, they shall be fined from ten million to one hundred million, not confined to three years or imprisonment from six months to three years.+ Guilty of causing very serious consequences shall be imprisonment from two years to seven years.+ Guilty of particularly severe consequences shall be imprisonment from five years to ten years. The offender can be fined from five million to fifty million, all service, all practising or doing certain work from one year to five years.
