The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

Removal of heavy metals from wastewater using granular coalSaravanabawan, Thirugnana January 1980 (has links)
Batch tests were performed to evaluate the relative performance of four B.C. coals (Hat Creek Oxidised, Kaiser-stock pile refuse, Kaiser-special plant feed and Cominco Ash) in removing heavy metals copper, lead, zinc and mercury from filtered primary sewage treatment plant effluent. Emphasis was placed on metal concentrations of 10 mg/l and less. Hat Creek coal was found to be much superior to the other three and its efficiency is comparable to that of Darco activated carbon 12 x 20.
Hat Creek and Kaiser-stock pile refuse coals were further used in column tests to evaluate the relative performance of these coals in removing copper, lead and zinc under dynamic conditions. Again emphasis was placed on influent metal concentrations of 10 mg/1 and less and once more the performance of Hat Creek coal was much superior to that of Kaiser coal. Tests with activated carbon indicate Hat Creek coal to be a close competitor for use in advanced waste treatment for heavy metal removal. / Applied Science, Faculty of / Civil Engineering, Department of / Graduate

Assessment of Contamination Levels and Estimation of Dietary Intake of Heavy Metals from Selected Imported Fruits and Vegetables in GhanaDzimado, Eric 07 May 2016 (has links)
Levels and dietary intake of heavy metals were assessed and evaluated in thirty two samples of fruit and vegetables collected from supermarkets in Accra, Ghana using atomic absorption spectroscopy. Differences (p <= 0.05) existed in Pb, Cd and Ni concentrations across the commodities collected. Levels of Pb, Cd and Cr exceeded safe limits established by FAO and EU. Washing reduced Cr in cabbage by 59% (p <= 0.05) but only reduced Pb in grapes by 12% (p ˃ 0.05). Estimated daily and weekly intake through fruit and vegetable consumption were below provitional tolerable dietary intake established by the FAO. Although estimated dietary intake obtained in this study were below the maximum established limits, increased comsumption of these fruit and vegetables may bring about adverse health implications for the exposed population.
