Download or read book In Situ Immobilization of Heavy Metal contaminated Soils written by G. Czupyrna and published by Taylor & Francis. This book was released on 1989-12-31 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many waste solutions and sludges contaminated with heavy metals are generated during aircraft maintenance operations at various Air Force Air Logistics Centers. The disposal of these waste streams by previously acceptable means has led to problems with the contamination of both soil and groundwater. Available technologies for treating contaminated soils are expensive. In situ immobilization of heavy metals is a cost-effective treatment alternative to alleviate the environmental and health hazards associated with contaminated soils. The objective of the program was the laboratory evaluation of various treatment chemicals for the in situ immobilization of hexavalent chromium, cadmium, nickel, copper and zinc in soils from Air Force facilities in the United States.

Download or read book Groundwater and Soil Cleanup written by National Research Council and published by National Academies Press. This book was released on 1999-11-21 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive, up-to-date review of technologies for cleaning up contaminants in groundwater and soil. It provides a special focus on three classes of contaminants that have proven very difficult to treat once released to the subsurface: metals, radionuclides, and dense nonaqueous-phase liquids such as chlorinated solvents. Groundwater and Soil Cleanup was commissioned by the Department of Energy (DOE) as part of its program to clean up contamination in the nuclear weapons production complex. In addition to a review of remediation technologies, the book describes new trends in regulation of contaminated sites and assesses DOE's program for developing new subsurface cleanup technologies.

Download or read book Toxicological Profile for Chromium written by U.s. Department of Health and Human Services and published by Createspace Independent Publishing Platform. This book was released on 2014-01-22 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: This toxicological profile is prepared in accordance with guidelines developed by the Agency for Toxic Substances and Disease Registry (ATSDR) and the Environmental Protection Agency (EPA). The original guidelines were published in the Federal Register on April 17, 1987. Each profile will be revised and republished as necessary. The ATSDR toxicological profile succinctly characterizes the toxicologic and adverse health effects information for the toxic substances each profile describes. Each peer-reviewed profile identifies and reviews the key literature that describes a substance's toxicologic properties. Other pertinent literature is also presented but is described in less detail than the key studies. The profile is not intended to be an exhaustive document; however, more comprehensive sources of specialty information are referenced. The profiles focus on health and toxicologic information; therefore, each toxicological profile begins with a public health statement that describes, in nontechnical language, a substance's relevant toxicological properties. Following the public health statement is information concerning levels of significant human exposure and, where known, significant health effects. A health effects summary describes the adequacy of information to determine a substance's health effects. ATSDR identifies data needs that are significant to protection of public health. Each profile: (A) Examines, summarizes, and interprets available toxicologic information and epidemiologic evaluations on a toxic substance to ascertain the levels of significant human exposure for the substance and the associated acute, subacute, and chronic health effects; (B) Determines whether adequate information on the health effects of each substance is available or being developed to determine levels of exposure that present a significant risk to human health of acute, subacute, and chronic health effects; and (C) Where appropriate, identifies toxicologic testing needed to identify the types or levels of exposure that may present significant risk of adverse health effects in humans.
Download or read book Sustainable Phytoremediation of Chromium VI Contaminated Soil and Tetrachloroethylene PCE Trichloroethylene TCE Contaminated Groundwater from a Superfund Site Using Sunflower Helianthus Annuus L written by Md Hadiuzzaman and published by . This book was released on 2019 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cr (VI) contaminated soil and tetrachloroethylene (PCE)/trichloroethylene (TCE) contaminated groundwater from a Superfund site were phytoremediated using sunflower (Helianthus annuus L.), a plant with strong adaptability and a hyperaccumulator which possesses great potential for phytoremediation. The Cr (VI) concentration was low of 0.16±0.04 mg/kg in the contaminated soil, and concentrations of PCE and TCE in irrigation water used to reflect influence of groundwater were 2.68±0.27 and 0.80±0.14 mg/L, respectively. For Cr (VI) remediation, physical characteristics, uptake of Cr (VI), bioaccumulation factor (BAF) and translocation factor (TF) were quantified. Analysis of the plants and the soils suggested that Cr (VI) was phytoextracted by roots, then transported from roots to shoots, leaves, seeds and stored within the parts. Both low nitrogen chemical fertilizer and biosolids were used as soil amendments to compare the efficiency of both the amendments on phytoextraction of Cr (VI), and the biosolids treated soil plants showed comparable phytoextraction to low nitrogen fertilizer treated soil plants. During the remediation of Cr (VI) from the co-contaminated soil matrix of both Cr (VI) and PCE/TCE, PCE and TCE were removed >99.9% from the soil matrix while Cr (VI) remediation, and neither PCE nor TCE were detected in effluents, plant tissues and soils after phytoremediation. The remediation of PCE/TCE were accomplished possibly by plant dehalogenation, degradation, plant volatilization, or soil volatilization. Cr (VI) in plant seeds from the contaminated soil plants was 0.36±0.08 mg/kg, which is much lower than the limit of 5.00 mg/kg in soil that will bring health concern. Concerning biodiesel properties, acid value and density were within American Society for Testing and Materials (ASTM) standard limits. Therefore, the produced biodiesel could be used as a potential renewable fuel. In addition, microbial biomass in rhizosphere soil was also studied before and after the remediation. The results showed that after phytoremediation, both biomass carbon and nitrogen increased for both Cr (VI) contaminated and Cr (VI)/PCE/ TCE co-contaminated rhizosphere soil, compared to their control ones. Increase of biomass carbon and nitrogen should be due to and could help the phytoremediation process. In sum, phytoremediation of low concentration Cr (VI) using H. annuus L. with biodiesel production could be a sustainable approach for solving both the environmental pollution problem and the energy crisis issue.
