  • Soil degradation, a deepening problem

    Land is increasingly encountering problems which cause soil degradation. Erosion, desiccation and salinisation are just a few examples. The result is that fertile top layers of the soil disappear, water infiltration deteriorates and surface discharge accelerates. This constant decline in soil fertility, productivity and cultural and recreational value has many negative effects, particularly for ...

  • Estimation of OCDD degradation rate in soil

    The current concentrations of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) were determined in soils contaminated with Chinese technical product sodium pentachlorophenate (Na-PCP). The estimated half-life of octachlorodioxin (OCDD) was about 14 years in contaminated soils based on the local historical record and mass balance calculation during the past 43 years (1960-2003). The ...

  • Analysis of atrazine and its degradation products in loamy soil by SPE and HPLC

    The degradation and leaching of atrazine and its degradation products (hydroxyatrazine, desethylatrazine, deisopropylatarzine and didealkylatrazine) were studied into loamy soil. An agriculture soil field (50 × 50 sq. feet with brinjal plants) was selected and atrazine spray was carried out once in a year. The irrigation of this plot was carried out once in a month. The sampling of soil was ...

  • Globalisation and rural poverty in Latin America: modelling the links to soil degradation

    The main objective of this paper is to present a framework to evaluate the impact of globalisation on poor farmers. We present a dynamic ecological-economic model that can be used to quantify the impact of globalisation on farmers' income and the quality of their natural resource base. The model combines material flux analysis with economic behavioural relationships. It allows for: (i) measuring ...

  • Degradation rate of sodium fluoroacetate in three New Zealand soils

    The degradation rate of sodium fluoroacetate (SFA) was assessed in a laboratory microcosm study incorporating three NZ soil types under different temperature (5, 10 or 20 °C) and soil moisture (35% or 60% water holding capacity) conditions using OECD Guideline 307. A combination of non‐labelled and radio‐labelled 14C‐SFA was added to soil microcosms, with sampling and analysis protocols for ...

  • Production and recovery of poly-β-hydroxybutyrate from whey degradation by azotobacter

    Poly-β hydroxyl-butyrate, (PHB) is a biodegradable thermoplastic which can be extracted from a wide range of bacteria. PHB belongs to the class of bacterial polyesters collectively called polyhydroxyalkanoates, (PHAs). PHAs have properties similar to polypropylene and are important due to their complete biodegradability, with recognised potential applications in reducing disposable waste ...

  • Degradability of n-hexadecane by Bacillus cereus DQ01 isolated from oil contaminated soil from Daqing oil field, China

    Localisation of degradation enzyme in Bacillus cereus DQ01 for n-hexadecane, production and characteristics of n-hexadecane-degrading enzyme were studied in this paper. The cellular extracts of Bacillus cereus DQ01 were fractionated into extra-cellular, periplasmic and cytoplasmic fractions after osmotic shock. The results showed that cytoplasmic and periplasmic enzymes are mainly responsible for ...

  • Isolation and characterization of some polycyclic aromatic hydrocarbon degrading bacteria from Nsukka soils in Nigeria

    Abstract: Twenty-four bacteria capable of utilizing naphthalene, as their sole source of carbon and energy for growth were isolated from three different sites in Nsukka, Nigeria. By standard bacteriological methods, these bacteria were characterized taxonomically as belonging to the genus Pseudomonas, Burkholderia or Actinomycetes. Two of the isolates, which showed the highest growth during ...

  • Isolation and characterization of crude oil degrading bacillus spp.

    Crude oil continues to be used as the principal source of energy and play an important role in the global environmental pollutant considerations. On the other hand, oil will remain as a major source of energy in the next several decades, because a reliable alternative energy comsumption has not yet been substituted. (Trindade et al., 2005, Al- Saleh and Obuekwe, 2005). There are so many bacterial ...

  • Bioremediation of soil

    In our experience, Bioremediation is best accomplished with Bio-augmentation, the addition of large numbers of selected micro-organisms grown in the production laboratory. In addition to bio-augmentation, several physical and chemical parameters must be controlled in order to obtain optimal growth and maximum degradation of soil contaminants. The major factors that are controlled during ...

  • Soil Fracturing

    Introduction Fracturing is an enhancement technology designed to increase the efficiency of other in situ technologies in difficult soil conditions. The fracturing extends and enlarges existing fissures and introduces new fractures, primarily in the horizontal direction. When fracturing has been completed, the formation is then subjected to vapor extraction, either by applying a vacuum to all ...

  • Assessing the impact of climate change on water resources, crop production and land degradation in a semi-arid river basin

    The semi-arid regions of Iran have experienced severe water resources stress due to natural (e.g., drought) and anthropogenic (e.g., depletion of water in various sectors) factors. Assessing the impact of climate change on water resources and crop production could significantly help toward better water management and hence prevention of land degradation in this area. A hydrological model of ...

  • Isolation, development and identification of salt-tolerant bacterial consortium from crude-oil-contaminated soil for degradation of di-azo dye Reactive Blue 220

    The objective of this study was development and characterization of a halophilic bacterial consortium for rapid decolorization and degradation of a wide range of dyes and their mixtures. The 16S rRNA gene analysis of developed halophilic consortium VN.1 showed that the bacterial consortium contained six bacterial strains, which were identified as Pseudomonas fluorescens HM480360, ...

  • Degradation of aromatic compounds using moving bed biofilm reactors

    The removal of toxic phenolic compounds from industrial wastewater is an important issue to be addressed. Phenolic compounds such as phenol, hydroquinone and pyrogallol are used in different industries which end into their wastewaters. They are considered as priority pollutants because of their high toxicity at low concentrations. Phenol is an important raw material in petrochemical, ...

  • Radar remote sensing of wind-driven land degradation processes in northeastern Patagonia

    Received for publication February 27, 2009. Wind-driven land degradation negatively impacts on rangeland production and infrastructure in the Valdes Peninsula, northeastern Patagonia. The Valdes Peninsula has the most noticeable dunefields of the Patagonian drylands. Wind erosion has been assessed at different scales in this region, but often with limited data. In general, terrain features caused ...

  • Threats to soil quality in Europe

    During the recent years, there has been a surge of concern and attention in Europe to soil degradation processes. Initiated by the German Ministry for Environment in 1998 with the first European Soil Forum a process has been developing over the past ten years leading to the adoption by the European Commission in September 2006 of the Thematic Strategy for Soil Protection including a proposal for ...


  • Natural Attenuation in Soils

    Introduction Surface and subsurface soils have different characteristics in natural attenuation. Mobile contaminants in subsurface soils diffuse into soil vapor and aqueous phase and thus are relatively easily subject to natural subsurface processes that can attenuate these contaminants. Most high-molecular-weight (persistent) organic and many inorganic contaminants will be immobilized in the ...
