35 editions published between 1996 and 1997 in English and held by 35 libraries worldwide
Vapor space characterization of waste tank 241-TX-118 (in situ) : results from samples collected on 9/7/94 ( Book )
1 edition published in 1995 in English and held by 3 libraries worldwide
This report describes inorganic and organic analyses results from in situ samples obtained from the headspace of the Hanford waste storage Tank 241-TX-118 (referred to as Tank TX-118). The results described here were obtained to support safety and toxicological evaluations. A summary of the results for inorganic and organic analytes is listed in Table 1. Detailed descriptions of the results appear in the text. Quantitative results were obtained for the inorganic compounds ammonia (NH[sub 3]), nitrogen dioxide (NO[sub 2]), nitric oxide (NO), hydrogen cyanide (CHN), and water (H[sub 2]O). Sampling for sulfur oxides (SO[sub x]) was not requested. In addition, quantitative results were obtained for the 39 TO-14 compounds plus an additional 13 analytes. Hexane, normally included in the additional analytes, was removed because a calibration standard was not available during analysis of Tank TX-118 SUMMA[trademark] canisters. Of these, 12 were observed above the 5-ppbv reporting cutoff. Fourteen tentatively identified compounds (TICs) were observed above the reporting cutoff of (ca.) 10 ppbv and are reported with concentrations that are semiquantitative estimates based on internal-standard response factors. The 10 organic analytes with the highest estimated concentrations are listed in Table 1 and account for approximately 86% of the total organic components in Tank TX-118. Permanent gas analysis was not conducted on the tank-headspace samples. Tank TX-118 is on both the Ferrocyanide and Organic Watch List

Headspace vapor characterization of Hanford waste tank 241-S-112 : results from samples collected on 7/11/95 ( Book )
2 editions published between 1996 and 1997 in English and held by 2 libraries worldwide
This report describes the results of vapor samples taken from the headspace of waste storage Tank 241-S-112 (Tank S-112) at the Hanford. Pacific Northwest National Laboratory (PNNL) is contracted with Westinghouse Hanford Company (WHC) to provide sampling devices and analyze samples for inorganic and organic analytes collected from the tank headspace and ambient air near the tank. The analytical work was performed by the PNNL Vapor Analytical Laboratory (VAL) by the Tank Vapor Characterization Project. Work performed was based on a sample and analysis plan (SAP) prepared by WHC. The SAP provided job-specific instructions for samples, analyses, and reporting. The SAP for this sample job was {open_quotes}Vapor Sampling and Analysis Plan{close_quotes}, and the sample job was designated S5044. Samples were collected by WHC on July 11, 1995, using the Vapor Sampling System (VSS), a truck-based sampling method using a heated probe inserted into the tank headspace
Vapor space characterization of waste tank 241-C-108 : results from samples collected through the vapor samping system on 8/5/94 ( Book )
2 editions published in 1995 in English and held by 2 libraries worldwide
This report describes inorganic and organic analyses results from samples obtained from the headspace of the Hanford waste storage Tank 241-BY-108 (referred to as Tank BY-108). The results described here were obtained to support safety and toxicological evaluations. A summary of the results for inorganic and organic analytes is listed in Table 1. Detailed descriptions of the results appear in the text. Quantitative results were obtained for the inorganic compounds ammonia (NH[sub 3]), nitrogen dioxide (NO[sub 2]), nitric oxide (NO), and water vapor (H[sub 2]O). Trends in NH[sub 3] and H[sub 2]O samples indicated a possible sampling problem. Sampling for hydrogen cyanide (HCN) and sulfur oxides (SO[sub x]) was not requested. In addition, the authors looked for the 40 TO-14 compounds plus an additional 15 analytes. Of these, 17 were observed above the 5-ppbv reporting cutoff. Also, eighty-one organic tentatively identified compounds (TICs) were observed above the reporting cutoff (ca.) 10 ppbv, and are reported with concentrations that are semiquantitative estimates based on internal standard response factors. The nine organic analytes with the highest estimated concentrations are listed in Summary Table 1 and account for approximately 48% of the total organic components in the headspace of Tank BY-108. Three permanent gases, hydrogen (H[sub 2]), carbon dioxide (CO[sub 2]), and nitrous oxide (N[sub 2]O) were also detected. Tank BY-108 is on the Ferrocyanide Watch List

Vapor space characterization of waste tank 241-C-106 : results from samples collected on 2/15/94 ( Book )
2 editions published in 1995 in English and held by 2 libraries worldwide
This report describes inorganic and organic analyses results from in situ samples obtained from the headspace of the Hanford waste storage Tank 241-U-106 (referred to as Tank U-106). The results described here were obtained to support safety and toxicological evaluations. A summary of the results for inorganic and organic analytes is listed in Table 1. Detailed descriptions of the results appear in the text. Quantitative results were obtained for the inorganic compounds ammonia (NH[sub 3]), nitrogen dioxide (NO[sub 2]), nitric oxide (NO), and water (H[sub 2]O). Sampling for hydrogen cyanide (HCN) and sulfur oxides (SO[sub x]) was not performed. In addition, the authors looked for the 39 TO-14 compounds plus an additional 14 target analytes. Of these, six were observed above the 5-ppbv reporting cutoff. Ten organic tentatively identified compounds (TICs) were observed above the reporting cutoff of (ca.) 10 ppbv in two or more of the three samples collected and are reported with concentrations that are semiquantitative estimates based on internal standard response factors. The 10 organic analytes with the highest estimated concentrations are listed in Table 1 and account for approximately 89% of the total organic components in Tank U-106. Methyl isocyanate, a compound of possible concern in Tank U-106, was not detected. Tank U-106 is on the Organic Watch List
Evaluate and characterize mechanisms controlling transport, fate, and effects of army smokes in the aerosol wind tunnel transport, transformation, fate, and terrestrial ecological effects of hexachloroethane obscurant smokes by D. A Cataldo( Book )
1 edition published in 1987 in English and held by 1 library worldwide
The terrestrial transport, chemical fate, and ecological effects of hexachloroethane (HC) smoke were evaluated under controlled wind tunnel conditions. Primary objectives of this research are to characterize and assess the impacts of smoke and obscurants on: 1) natural vegetation characteristic of U.S. Army training sites in the U.S.; 2) physical and chemical properties of soils representative of these training sites; and 3) soil microbiological and invertebrate communities. Impacts and dose/responses were evaluated based on exposure scenarios, including exposure duration, exposure rate, and sequential cumulative dosing. Key to understanding the environmental impacts of HC smoke/obscurants is establishing the importance of environmental parameters such as relative humidity and wind speed on airborne aerosol characteristics and deposition to receptor surfaces. Direct and indirect biotic effects were evaluated using 5 plant species and 2 soil types. Based on a deposited foliar dose (mass loading) of 12 to 40 microgram HC/cc, equivalent to 1- to 4-h exposure to smokes at 450 mg/cu.m. air, plant toxicity responses are judged low to moderate. Relative humidity has no dramatic effect on the quality or intensity of damage. Repetitive dosing at 2- to 3-day intervals resulted in substantially more damage than indicated by the total delivered dose. The observed effects likely result from the accumulation of Zn from foliar surfaces and subsequent toxicity. Residual effects are apparent, although not severe in several of the test series. (EDC)
Acute Toxicity of Smoke Screen Materials to Aquatic Organisms, White Phosphorus-Felt, Red Phosphorus-Butyl Rubber and SGF (Smoke Generator Fuel) No. 2 Fog Oil ( Book )
1 edition published in 1986 in English and held by 1 library worldwide
The acute toxicity of three obscurants was determined for nine fresh- water organisms. The materials tested were white phosphorus-felt smoke, red phosphorus-butyl rubber (RP-BR) smoke, and smoke generator fuel (SGF) No. 2 fog oil (bulk and vaporized). The chemistry of WP-F and RP-BR smoke in water and the resulting effects on aquatic organisms were similar. Combustion of these two obscurants and their deposition in water leads to the formation of many complex oxy-phosphoric acids. Rates of hydrolysis of these complex products to ortho- phosphate were inconsistent and unpredictable over time. These products acidify water and produce toxic effects after exhausting the buffering capacity of the water. The 96-hr median lethal concentration (LC50) values for fish ranged from 3.9 to 5.1 pH units. The values for invertebrates ranged from 3.4 to 5.5. Algal growth was inhibited at pH levels less than 6.0. Acute 96 hr tests using Daphnia magna with neutralized and nonneutralized exposure solutions indicated that the presence of unidentified toxic component(s) acted independently of pH. Additions of phosphorus into aquatic systems can lead to stimulation of algal growth as long as the resulting pH is not toxic. Neither the bulk fog oil nor the vaporized fog oil was acutely toxic to freshwater animals at concentrations less than 10 mg/l total oil. Concentrations of bulk fog oil in excess of 2.4 mg/l total oil significantly inhibited algal growth in two of the three batches tested. Photolysis increased the concentration of water-soluble components of the fog oil. The three obscurants tested have the potential for adverse environmental effects
