Trace Metal Concentrations Across Trophic Levels In Cotton Fields Of Xinjiang Province, China, Jessica Quinn

All Student Theses and Dissertations

Trace metals become concentrated in urban and peri-urban soils with the use of agricultural practices and industrial emissions. Fertilizers, liming, sewage sludge, and irrigation water contain metals which accumulate in agricultural fields and pose a risk to humans and wildlife. Coal plants and brickyards release metals into the atmosphere which are deposited on soil and plant surfaces. This research quantifies the concentrations of nine trace metals in three different soil types. A total of 116 rodents were sampled in cotton fields and a desert. Cotton plants and triplicate soil samples were collected with each rodent capture. Soil samples were analyzed …

Indivisible Injury Negligence And Nuisance Cases –Proving Causation Among Multiple-Source Polluters: A State-By-State Survey Of The Law For New England, And A Proposal For A New Causation Framework, Paul Homer

The University of New Hampshire Law Review

[Excerpt] "The skies, soil, and water of every state are polluted every day. Whether the pollutants enter the atmos phere from coal plants or the water-ways from large farms, materials a bnormal to the “natural” environment are regularly emitted by a variety of sources over wide regions of the nation. To some extent, such emissions are normal and acceptable activities in modern society."

Heavy Metal Contamination Of Mangrove Sediments And The Associated Biota In Dar Es Salaam, Tanzania, Sd Mremi, Jf Machiwa

Tanzania Journal of Science

Mangrove wetlands are efficient in trapping pollutants that may have detrimental effects on mangrove dependent food chains. Mangrove ecosystems that are within urban areas are likely to suffer more from chemical pollution than those in rural areas. Heavy metals in mangrove plant parts, sediments and crabs from mbweni, msimbazi and mtoni mangrove ecosystems in Dar es salaam were analysed using an atomic absorption spectrophotometer, in order to assess the impact of heavy metal pollution on mangrove biota. Sediment samples from msimbazi and mtoni mangrove areas which are located within the city, had higher levels of pb, zn and cu than …

Optimization Of Edxrf For The Study Of Heavy Metal Pollution Of Lake Victoria, Nk Mahommed, In Makundi

Tanzania Journal of Science

This study reports on the optimisation and calibration of the Energy Dispersive X-ray Fluorescence (EDXRF) spectrometer installed in the Department of Physics, University of Dar es Salaam. The spectrometer was subsequently utilized to determine concentrations of heavy metals in water hyacinth (Eichhornia crassipes (Mart) Solms.) found growing along the shore of Lake Victoria. The optimal conditions and detection limits were determined experimentally by variation of the excitation parameters. The study found that the use of a collimator with two apertures of diameter 4 mm each placed 8 mm apart and made of materials that do not interfere with elements to …

Assessment Of Heavy Metal Pollution In The Lupa Gold Field, Sw Tanzania, S. R. Mnali

Tanzania Journal of Science

The concentrations of AS, Cd, Cr, Cu, Hg and Pb were determined in water, stream sediments, soil, and mine tailings from Lupa Gold Field (LGF), SW Tanzania, in order to assess their pollution levels. As, Cd and Cr were determined by automated Graphite Furnace Absorption Spectrophotometry. Cu and Pb were analysed by Air-Acetylene Flame, while Hg was analysed by Cold Vapour Atomic Absorption Spectrophotometry. The mean concentrations obtained were: As: 0.44 ppb (water), 1.2 ppm (sediments), 0.44 ppm (soil) and 5.2 ppm (tailings); Cd: 0.03 ppb (water), 0.03 ppm (sediments), 0.03 ppm (soil) and 0.50 ppm (tailings); Cr: 1.4 ppb …

Heavy Metals And Organic Pollutants In Sediments Of Dar Es Salaam Harbour Prior To Dredging In 1999, J F Machiwa

Tanzania Journal of Science

Heavy metals and organic contaminants were analysed in the sediments of the inner area of the Dar es Salaam harbour. Complementary analytical parameters, such as, the organic carbon content and the silt/clay fraction of the sediments showed good positive correlation (r = 0.64). Stations that had high content of fine grain material in the sediment also indicated relatively high level of organic carbon and pollutants. The Florida criteria (MacDonald 1993) for assessment of pollution of tropical marine sediments was adopted in oredr to evaluate the extent of pollution in Dar es Salaam harbour sediments. The Florida criteria is one of …

Toxics Use Reduction: Pro And Con, Francine Laden, George M. Gray

RISK: Health, Safety & Environment (1990-2002)

With the Massachusetts Toxics Use Reduction Act as an example, important issues related to the goals and effectiveness of TUR are examined. The benefits as claimed by proponents are contrasted with shortcomings outlined by opponents in point-counterpoint style. Ultimately, the authors call for more balanced analysis.

Regulating Air Toxics In Rhode Island: Policy Vs. Technical Decisions, Julie A. Roque

RISK: Health, Safety & Environment (1990-2002)

Dr. Roqu6 recounts her work as a doctoral candidate at Brown in developing standards for the regulation of airborne carcinogens. Based in part on this experience, she argues that care needs be taken lest those who regulate Risk bury key policy decisions within a mass of often irrelevant technical details.
