متن کاملRemediation of soil co-contaminated with pyrene and cadmium by growing maize (Zea mays L.)
Sites co-contaminated with organic and metal pollutants are common and considered to be a more complex problem as the two components often causes a synergistic effect on cytotoxicity. Phytoremediation has been proposed as a cost-effective technology for treating heavy metal or organic contamination and may be suitable for remediation of co-contaminated soil. This study investigated the concurre...
متن کاملBiochar for soil remediation and land reclamation
Land reclamation generally relates to the improvement of soils degraded by human activities, for example construction and certain forms of agriculture. Soil remediation refers to the process of removing, neutralizing or reducing the toxicity of certain compounds, often left by human activities such as mining and industry. Each degraded and/or contaminated site is potentially unique in its chara...
متن کاملEnhanced electrokinetic remediation of cadmium contaminated soils by chelating agents
Electrokinetic soil remediation by electroosmosis and ionic migration is restricted to soluble substances. At a higher pH, the soil particles sorb more heavy metals than at a lower pH and the precipitation reactions of heavy metals are promoted. Both mechanisms make heavy metals immobile, rendering cleanup more difficult and electrokinetic extraction inefficient. In this study, the effectivenes...
متن کاملEffects of Spartina alterniflora Invasion on Soil Quality in Coastal Wetland of Beibu Gulf of South China
BACKGROUND Since Spartina alterniflora (simplified as Spartina) has strong ecological competitiveness and rapid growth, it has been introduced and living in the coastal wetland regions of China for more than 30 years. Taking coastal wetland in the Beibu Gulf of south China as an example, the effects of Spartina invasion on soil quality were investigated to provide scientific basis for soil mana...
