In The Beginning

Contaminated land sites in Finland was investigated in the beginning of 1990' s. About 10 000 sites were suspected to be polluted. Typical cases of soil contamination are sawmills, wood impregnation plants, waste treatment plants, garages and scrap yards. It is estimated that about 1200 sites need remediation actions. Estimated costs of restoration are FIM 5.4 billion over the next 20 years. Legislation has been changed to concern soil pollution. However old and hostless contaminated soil sites have legal and economic problems. The resources meant to solve soil pollution have increased rapidly during last years in Finland.

Soil pollution is rising rapidly due to the existence of pollutants or natural alterations in the soil. It makes the drinking water ineffective and unusable by the human beings. The major cause of the soil contamination is agricultural activities, industrial activities, and inadmissible disposal of waste in the soil. The most common pollutants to accumulate in the soil are petroleum hydrocarbons, solvents, pesticides, lead, and other heavy metals. The important technology to remediate the pollutants or contaminants in the soil is bioremediation. The utilization of bioremediation in the contaminated soil is increasing rapidly due to the presence of toxic pollutants. It is the most advanced technologies which make use of organisms to deteriorate the harmful compounds in order to prevent the soil pollution. The aim of the chapter is to describe the available bioremediation technologies and their application in removing the pollutants exist in the soil.

Biochar Amendment

Miscanthus × giganteus (M. × giganteus) is a perspective plant produced on marginal and contaminated lands with biomass used for energy or bioproducts. In the current study, M. × giganteus development was tested in the diesel-contaminated soils (ranged from 250 mg kg−1 to 5000 mg kg−1) and the growth dynamic, leaves quantity, plants total area, number of harvested stems and leaves, SPAD and NPQt parameters were evaluated. Results showed a remarkable M. × giganteus growth in a selected interval of diesel-contaminated soil with sufficient harvested biomass. The amendment of soil by biochar 1 (produced from wastewater sludge) and biochar 2 (produced from a mixture of wood waste and biohumus) improved the crop’s morphological and physiological parameters. Biochar 1 stimulated the increase of the stems’ biomass, while biochar 2 increased the leaves biomass. The plants growing in the uncontaminated soil decreased the content of NO3, pH (KCl), P2O5 and increased the content of NH4. Photosynthesis parameters showed that incorporating biochar 1 and biochar 2 to the diesel-contaminated soil prolonged the plants’ vegetation, which was more potent for biochar 1. M. × giganteus utilization united with biochar amendment can be recommended to remediate diesel-contaminated land in concentration range 250–5000 mg kg−1.

Three Dimensional Models

The method of three-dimensional model in the system of computer modeling MathCad and Autodesk 3ds Max by categories of total soil pollution is developed. A visualization block and an analytical block have been developed which are based on calculated mathematical models for analyzing and evaluating the environmental situation, risks, and environmental safety of the territory. Three-dimensional models of relief mapping of the Pekhorka river fl oodplain are constructed by integrating them with the help of a programming environment and optimized 3D modeling programs. Three-dimensional models with total soil contamination for water body sections are constructed. On the example of some sections of the catchment area of the Pekhorka river in the Balashikha region, models with soil contamination by the total ZC indicator were created. The development of 3D modeling techniques allows you to create predictive scenarios more accurately with a high degree of detail, as well as quickly approach the solution of environmental problems. Optimization of three-dimensional modeling in the fi eld of problems related to the catchment area contributes to the further operational solution of problems of rational land use and improvement of the environmental situation.

AbstractThe removal efficiency of two different types of peroxide addition, catalyzed hydrogen peroxide (CHP) and sodium percarbonate (SPC) were compared on a highly PAH-contaminated soil from a wood impregnation site. In an attempt to simulate real in situ reagents delivery, experiments have been carried out in acrylic columns. The main parameters affecting contaminant removal were the reagent’s temperature and the total addition of peroxide (g

Definition Of

<p>Odour emissions from liquid waste treatment plants (LWTPs) generally cause significant effects on the environment in terms of nuisance to exposed population. The particular and complex nature of the mixture of the volatile substances, its variability in time and the strong influence of the atmospheric conditions, are the elements that delayed their regulation and relative management.</p> <p>Limited data are available in the technical and scientific literature, regarding the odour emissions characterization from liquid waste treatment plants. Moreover there isn’t a common strategy from the different European Countries in the regulation of their emissions.</p> <p>Different methods can be used to measure odour emissions from environmental engineering plants, and currently, in Europe, the most used techniques for odour emissions characterization and quantification is the dynamic olfactometry, according to EN 13725:2003.</p> <p>The aim of this study is the characterization of the odour emissions from different liquid waste treatment plants (LWTPs), trough a case study of two large real LWTPs, in order to identify the principal odour sources and to define their related odour emissions.</p> <p>Odour Concentration Index (OCI) is proposed as a useful and simply odour management tool for the identification of the priority actions necessary to identify and control the main odorous sources. Relationship between the measured odour emissions and the types of treated liquid waste (identified in terms of EWC code, COD and NH4<sup>+</sup>) is also discussed.</p> <p>Results show that the influent collection tank is the source with the highest detected odour emissions. OCI results are useful for the definition of a clear priority action for odour control, similar for both investigated plants. Between the characterized types of liquid waste treated by LWTPs the leachate (EWC 190703) show the maximum odour emissions.</p>

This study examines various problems occurring in wetland clearing and uses in South Kalimantan. In the beginning, the wetland clearing aimed to expand the food crop area in order to implement government policies to meet the food needs. However, it has changed into the capitalist media and transmigration purposes. This study uses a historical perspective composing from heuristic to historiography with an ecological approach. Based on the findings, the land clearing was integrated with the transmigration program which had been started since the 1960s. The argument that can be developed in this study is that wetland-use expansion causes two basic problems in environmental management, namely the large volume of standing water and the relatively high acidity level. This expansion referred to the settlement developed around the wetlands which increasingly could not be controlled by the government. However, ideally, the existing situation had to show that wetland clearing has shifted should balance social, environmental, and economic values, of which the implementation to regulate self-productivity that actually has been running for generations.

This study is conducted to determine the activity of plant Vica faba and two isolated from arbuscular mycorrhizae fungi (A,B) in bioremediation of soil pollution by Nickel and Lead elements in north and south of Baghdad city. The results showed that the average of soil pollution by Nickel and Lead elements in north of Baghdad was less than the average of soil pollution in the south of Baghdad which recorded 29.0,9.0PPm and 42.0, 25.0PPm respectively. The results show that the isolate A from the polluted soil is more active from isolate B which isolate from unpolluted soil for bioremediation. Vica faba recorded more in accumulate the Lead element in shoot system which was 19.65PPm and in root system was 27.2PPm and for Nickel element 24.65, 27.55PPm in shoot and root respectively.
