A study of the metal content of municipal solid waste. Final report

A study of the metal content of municipal solid waste. Final report

Date: January 1, 1998
Creator: Churney, K.L. & Domalski, E.S.
Description: Knowledge of the content of toxic components, so called pollutant precursors, in the municipal solid waste (MSW) stream is essential to development of the strategies for source reduction and reuse, recycling, composting and disposal. Data are scarce; trends in composition for any locality even more so. In a previous study the total and water soluble chlorine content of the components of municipal solid waste were determined from sampling studies at two sites, Baltimore County, MD, and Brooklyn, NY, each for a five day period. The total sulfur content of the combined combustible components was also determined. Because of the scarcity of data and synergistic effects, it seemed appropriate to determine the heavy metal content of the preceding material prior to its disposal. The metals chosen were the so-called priority pollutant metals (PPM): antimony, arsenic, beryllium, cadmium, chromium, copper, lead, mercury, nickel, selenium, silver, thallium, and zinc.

Current radiological status of Utirik Atoll

Current radiological status of Utirik Atoll

Date: August 1, 1998
Creator: Robison, W L
Description: A preliminary radiological survey was conducted at Utirik Atoll in 1978 as part of the Northern Marshall Islands Radiological Survey (NMIRS). A dose assessment based on these limited data indicated a relatively low dose of about 0.12 mSv to people living on Utirik in 1978 (Robison et al., 1982). A much more detailed radiological survey was conducted in April of both 1993 and 1994. Aerial photos of the islands of Utirik Atoll were taken as part of the 1978 NMIRS. The sampling grids for the 1993 and 1994 surveys are shown overlaid on these aerial photos in Figures 1, 2, 3, and 4. External gamma measurements and a collection of either drinking coconuts or copra coconuts were made at each location. Pandanus, breadfruit, lime, and banana were collected where available. Ground water was collected in 1993/94 from four wells on Utirik Island and two wells on Aon Island. Surface soil and soil profiles were collected at some of the grid points on each of the islands at the atoll in 1993/94. A comparison of the number of samples collected in 1978 and 1993/94 are shown in Table 1. A detailed listing of the samples collected in the 1993/94 radiological survey ...

Radionuclide concentrations in pinto beans, sweet corn, and zucchini squash grown in Los Alamos Canyon at Los Alamos National Laboratory

Radionuclide concentrations in pinto beans, sweet corn, and zucchini squash grown in Los Alamos Canyon at Los Alamos National Laboratory

Date: May 1, 1997
Creator: Fresquez, P.R.; Mullen, M.A.; Naranjo, L. Jr. & Armstrong, D.R.
Description: Pinto beans, sweet corn, and zucchini squash (Cucurbita pepo var. black beauty) were grown in a randomized complete-block field/pot experiment at a site that contained the highest observed levels of surface gross gamma radioactivity within Los Alamos Canyon (LAC) at Los Alamos National Laboratory. Soils as well as washed edible and nonedible crop tissues were analyzed for various radionuclides and heavy metals . Most radionuclides, with the exception of {sup 3}H and {sup tot}U, in soil from LAC were detected in significantly higher concentrations (p <0.01) than in soil collected from regional background (RBG) locations. Similarly, most radionuclides in edible crop portions of beans, squash, and corn were detected in significantly higher (p <0.01 and 0.05) concentrations than RBG. Most soil-to-plant concentration ratios for radionuclides in edible and nonedible crop tissues from LAC were within the default values given by the Nuclear Regulatory Commission and Environmental Protection Agency. All heavy metals in soils, as well as edible and nonedible crop tissues grown in soils from LAC, were within RBG concentrations. Overall, the total maximum net positive committed effective dose equivalent (CEDE)--the CEDE plus two sigma for each radioisotope minus background and then all positive doses summed--to a hypothetical 50-year resident ...

Life-cycle analysis of alternative aviation fuels in GREET

Life-cycle analysis of alternative aviation fuels in GREET

Date: July 23, 2012
Creator: Elgowainy, A.; Han, J.; Wang, M.; Carter, N.; Stratton, R.; Hileman, J. et al.
Description: The Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREET) model, developed at Argonne National Laboratory, has been expanded to include well-to-wake (WTWa) analysis of aviation fuels and aircraft. This report documents the key WTWa stages and assumptions for fuels that represent alternatives to petroleum jet fuel. The aviation module in GREET consists of three spreadsheets that present detailed characterizations of well-to-pump and pump-to-wake parameters and WTWa results. By using the expanded GREET version (GREET1{_}2011), we estimate WTWa results for energy use (total, fossil, and petroleum energy) and greenhouse gas (GHG) emissions (carbon dioxide, methane, and nitrous oxide) for (1) each unit of energy (lower heating value) consumed by the aircraft or (2) each unit of distance traveled/ payload carried by the aircraft. The fuel pathways considered in this analysis include petroleum-based jet fuel from conventional and unconventional sources (i.e., oil sands); Fisher-Tropsch (FT) jet fuel from natural gas, coal, and biomass; bio-jet fuel from fast pyrolysis of cellulosic biomass; and bio-jet fuel from vegetable and algal oils, which falls under the American Society for Testing and Materials category of hydroprocessed esters and fatty acids. For aircraft operation, we considered six passenger aircraft classes and four freight aircraft classes ...
