Sludge application program at the Savannah River Plant

Since 1980 a research program has been conducted at the Savannah River Plant to evaluate the use of domestic sewage sludge to enhance forest productivity. The objectives of the program have been to determine the cost effectiveness and environmental impact of using sewage sludge as a soil conditioner and slow-release fertilizer. The potential impacts of sludge application on nutrient cycling, organic carbon budgets, forest wildlife, and biomass production have been studied. Soil, soil water, gro… more

Isotope studies to determine dry deposition of sulfate to deciduous and coniferous trees: Final draft

Experiments have been conducted at two locations near Oak Ridge, Tennessee, with radioactive /sup 35/S (87 day half-life) to examine the cycling behavior of sulfur in yellow poplar (Liriodendron tulipifera), red maple (Acer rubrum), and loblolly pine (Pinus taeda) trees. Some findings pertain to methods development for estimating dry deposition of sulfur to forest canopies and the magnitude of sulfur emissions from natural sources (Task II). We will determine through field studies, the internal… more

Acute Environmental Toxicity and Persistence of DEM, a Chemical Agent Simulant: Diethyl Malonate. [Diethyl Malonate]

The purpose of the following chemical simulant studies is to assess the potential acute environmental effects and persistence of diethyl malonate (DEM). Deposition velocities for DEM to soil surfaces ranged from 0.04 to 0.2 cm/sec. For foliar surfaces, deposition velocities ranged from 0.0002 cm/sec at low air concentrations to 0.05 cm/sec for high dose levels. The residence times or half-lives of DEM deposited to soils was 2 h for the fast component and 5 to 16 h for the residual material. DEM… more

Environmental and plant effects of sewage sludge application to forests and pastures

Digested sewage sludge was applied to pastures and tree plantations at 19 to 44 Mg/ha (dry weight) as part of a municipal sludge disposal program. The sludge had low concentrations of heavy metals and traces of /sup 137/Cs and /sup 60/Co. Monitoring of soils, soil solutions, and runoff indicated that N, P, heavy metals, and radionuclides were largely retained in the upper 15cm of the soil. Soil solutions had elevated NO/sub 3//sup /minus// concentrations often >100 mg/L, but no significant incr… more

Sigma Mesa: Background Elemental Concentrations in Soil and Vegetation, 1979

In 1979, soil and vegetation samples were collected on Sigma Mesa to provide background data before construction on the mesa. Elemental data are presented for soil, grass, juniper, pinon pine, and oak. None of the data looks out of the ordinary. The purpose of the sampling program was to acquire, before any disturbance, a set of data to be used as background for future impact analysis. 6 refs., 2 figs., 7 tabs.

The implications of concurrent increases in temperature and CO[sup 2] concentration for terrestrial C[sup 3] photosynthesis

This study utilizes a mechanistic model of lea photosynthesis to examine the potential quantitative significance of the interaction of rising atmospheric. Carbon dioxide concentration (C[sub a]) and temperature on leaf photosynthesis. Predictions are compared to experimental measurements in which plants have been grown either in elevated C[sub a] in the field for extended periods or from seed in controlled environments, to examine the interaction of low temperature with elevated C[sub a].

Combustion characteristics of Ponderosa Pine bark. Technical progress report No. 7, September 16, 1977--September 15, 1978

Significant quantities of wood residue fuels are presently being used in industrial steam generating facilities. Recent studies indicate that substantial additional quantities of wood residue fuels are available for energy generation in the form of steam and/or electricity. A limited data base on the combustion characteristics of wood residue fuels has resulted in the installation and operation of inefficient combustion systems for these fuels. This investigation of the combustion characteristi… more

The fate of radionuclides in sewage sludge applied to land

Municipal sewage sludge containing up to 12 pCi/g {sup 137}Cs, 20 pCi/g {sup 60}Co, and 300 ppm U was injected in a pasture (43 Mg/ha) and sprayed over a young pine plantation (34 Mg/ha). In the pasture, radionuclides were largely retained in the upper 15 cm of the soil, and only about 15% moved below 15 cm. Sludge rapidly infiltrated the soil on the pine plantation. One year after application, at least 85% of the {sup 137}Cs, {sup 60}Co, and U were found in the upper 7 cm of the pine plantatio… more

Investigation of the particle size distribution and particle density characteristics of Douglas fir hogged fuel fly ash collected under known combustion conditions. Technical Progress Report No. 2

The increased interest in wood as a fuel source, coupled with the increasing demand to control the emission generated by wood combustion, has created a need for information characterizing the emissions that occur for given combustion conditions. This investigation characterizes the carbon char and inorganic fly ash size and density distribution for each of thirty-eight Douglas fir bark samples collected under known conditions of combustion.
