  • Electrokinetic remediation study for cadmium contaminated soil

    Cadmium is a non-essential heavy metal pollutant of the environment resulting from various agricultural, mining and industrial activities and also from the exhaust gases of automobiles (Foy et al., 1978). Due to its high toxicity and greater solubility in water and its wide distributions in aquatic ecosystem, it has been considered as extremely significant pollutant (Lockwood, 1976). Great ...

  • Cadmium in soil-plant systems: an overview

    High concentrations of cadmium in soils represent a potential threat to human health because it is incorporated in the food chain mainly by plant uptake. The behaviour of cadmium in soils depends on several factors related to both soil and plant characteristics. This paper provides an overview of such factors as well as of the most environmentally friendly in situ soil remediation techniques in ...

  • Screening of a new cadmium hyperaccumulator Galinsoga parviflora from winter farmland weeds using the artificially‐high soil cadmium concentration method

    A new method, the artificially‐high soil cadmium (Cd) concentration method, was used to screen for Cd hyperaccumulators among winter farmland weeds. Galinsoga parviflora was the most promising remedial plant among five Cd accumulators or hyperaccumulators. In Cd concentration gradient experiments, as soil Cd concentration increased, root and shoot biomass decreased and their Cd contents ...

  • Inter‐species rootstocks affect cadmium accumulation in post‐grafting generation plants of potential Cd‐hyperaccumulator Solanum photeinocarpum

    Pot and field experiments were conducted to study the effects of inter‐species rootstocks on cadmium (Cd) accumulation characteristics of potential Cd‐hyperaccumulator Solanum photeinocarpum post‐grafting generation plants. Four treatments [ungrafted (UG) and S. photeinocarpum seedlings grafted on the rootstocks of eggplant (EG), potato (PG) and tomato (TG)] were utilized in present study. In ...

  • Properties and Behavior of Inorganics in Contaminated Soil

    Often, specific technologies may be ruled out, or the list of potential technologies may be immediately narrowed, on the basis of the presence or absence of one or more of the chemical groups. The relative amounts of each may tend to favor certain technologies. Metals may be found in the elemental form, but more often they are found as salts mixed in the soil. At the present time, treatment ...

  • In-Situ Remediation of Heavy Metals Using Sulfur-Based Treatment Technologies

    The Metal Problem Highly toxic and highly soluble metals are contained in numerous waste streams including those from power, chemical, electronics facilities, general manufacturing plants, and mining facilities. Lead, chromium, arsenic, zinc, cadmium, copper, and mercury are the most common metal contaminants found on remediation project sites (US EPA, October, 2000). Cyanide is a common ...

  • Trace metal characterization of soils using the Optima 7300 DV ICP-OES

    Soil testing helps diagnose soil health and guides in the development of soilspecific and crop-specific remedies. It is an indispensable tool to assure national food safety, nutritional accuracy, maintenance of soil health and enhancement of soil fertility. Based on this analysis, farmers may be advised on soil fertility to make agriculture more productive and sustainable. Micronutrient analysis ...

  • Removal of Cd, Pb, Cu and Zn from real contaminated soils with fresh and regenerated Na2EDTA

    The leaching efficiencies using both fresh Na2EDTA and regenerated Na2EDTA on the remediation of contaminated soils from Chenzhou lead–zinc mining area located in southern Hunan Province (southern China) were investigated. The total concentrations of Cd, Pb, Cu and Zn in both contaminated soils exceeded ...

  • Comparing Field Portable X-Ray Fluorescence (XRF) To Laboratory Analysis Of Heavy Metals In Soil

    ABSTRACT Field portable x-ray fluorescence (XRF) continues to gain acceptance as a complement to traditional laboratory testing of metal contaminated soil. The quality of data produced by field XRF varies with site conditions, soil composition, and sample preparation. Quality assurance protocols for the field method usually require that a number of field samples be split and sent to a ...

  • Metals Stabilization Using Geochemical Fixation

    Introduction To Chemical Fixation There are several approaches to treatment of chromium and other toxic metals such as lead arsenic, and cadmium in soil and groundwater, including isolation, immobilization, toxicity reduction, physical separation, and extraction (U.S. EPA. 2002). Brief Overview Of Metals Remediation Methods: Conventional ...

  • Climate change connections

    MY son has a friend whose mother loves him very much. She loves him so much that she is terrified, absolutely terrified, that something might hurt him. Because she loves him so much and is so afraid that something bad might happen to him, she seems determined not to let anything happen to him. He is not allowed to take city buses, go to his high school football games or ride his bike in the city ...

  • Incineration

    Introduction: High temperatures, 870 to 1,200 °C (1,400 to 2,200 °F), are used to volatilize and combust (in the presence of oxygen) halogenated and other refractory organics in hazardous wastes. Often auxiliary fuels are employed to initiate and sustain combustion. The destruction and removal efficiency (DRE) for properly operated incinerators exceeds the 99.99% requirement for hazardous waste ...

  • What Effect Does E-Waste Have On Groundwater?

    Groundwater is one of the most precious resources on Earth. Its yields supply water to nearly every community in the country, and without it, most of us would be driven to drastic measures to accommodate drought conditions. In fact, that very situation is happening in communities across the nation. As groundwater is increasingly negatively ...
