Enhanced biodegradation of PAHs in historically

01/09/2017 · The inoculation of rice straw biochar with PAH-degrading Mycobacterium gilvum (1.27 × 10 11 ± 1.24 × 10 10 cell g −1), and the subsequent amendment of this composite material to PAHs contaminated (677 mg kg −1) coke plant soil, was conducted in order to investigate if would enhance PAHs biodegradation in soils.The microbe-biochar composite showed superior degradation capacity …

Sustainable Energy Systems in Architectural Design: A

Pollution Abetment Consideration According to a 1999 study report by the U.S. Department of Energy (DOE), one kilowatt of energy produced by a coal fired electrical power generating plant requires about 5 lb of coal. Likewise generation of 1.5 kW hour of electrical energy per year requires about 7,400 lb of coal that in turn produces 10,000 lb of carbon dioxide (CO2). Commercial energy

Sources and gas-particle partitioning of atmospheric

01/06/2019 · As shown in Fig. 2, PHE, FLUA, and PYR were the most abundant PAHs congeners with annual mean concentrations of 13.6, 10.8, and 5.66 ng/m 3, accounting for 16.9%, 13.4%, and 7.0% of the total PAHs, respectively.High levels of these compounds may indicate biomass burning and/or coal combustion sources (Bragato et al., 2012; Khalili et al., 1995; Kulkarni and Venkataraman, 2000; Oanh …

Use of nitrate to stimulate the biodegradation of

Oxygen, usually the most efficient electron acceptor, is only sparingly soluble in water and may not be provided to the sediment at a sufficient rate to meet the demand. Nitrate can be used as an alternative electron acceptor by denitrifying microorganisms, is very water soluble, and yields relatively innocuous gaseous products which can leave the system upon reduction. In laboratory

International contracts to restrict emissions of climate-relevant gases, and thus global warming, also require a critical reconsideration of technologies for treating municipal, commercial, industrial, and agricultural waste gas emissions. A change from energy- and resource-intensive technologies, such as thermal post-combustion and adsorption, as well to low-emission technologies with high
