Abstract:

This thesis deals with the synthesis and development of 18F-labelled alkyl etomidate and vorozole analogues, and their use as positron emission tomography (PET) tracers for the imaging of the steroid enzymes 11β-hydroxylase and aromatase. Two synthetic 18F-labelling approaches to the etomidate and vorozole analogues were developed, and the analogues were evaluated in some biological assays. The two-step labelling method was used to synthesise many compounds for biological evaluation. In the first step, a 18F-labelled intermediate based on a ditosylate or a halogenated diethyl ether was synthes

Abstract:

Persistent organic pollutants (POPs) such as the organochlorine pesticide hexachlorocyclohexane (HCH) may undergo atmospheric transport and accumulate in regions remote from the source. It is important to develop techniques to help apportion source and identify transport or transformation processes to which HCHs and other mobile POPs may be subjected. Molecular tracers such as compound specific stable isotope and enantiomer ratios (ERs) may prove valuable in studying POP fate and transport. The objective of this study was to further develop the use of these two novel geochemical tools to evalu

Abstract:

Ionic materials in solution do not penetrate the skin following local (topical) application. Such a low permeability can, however, be altered by iontophoresis. Utilization of transmission and scanning electron microscopy and cryostat techniques has made it possible to demonstrate the penetration and site of deposition of ionic tracers in the skin of the rat. It has been found that the penetration of cationic dyes and metal cations is facilitated by positive iontophoresis while the penetration of anionic dyes is facilitated by negative iontophoresis. The extent of penetration is determined by t

Abstract:

Carbon-14 was measured in the dissolved organic carbon (DOC) in ground water and compared with ¹⁴C analyses of dissolved inorganic carbon (DIC). Two field sites were used for this study; the Stripa mine in central Sweden, and the Milk River Aquifer in southern Alberta, Canada. The Stripa mine consists of a Precambrian granite dominated by fracture flow, while the Milk River Aquifer is a Cretaceous sandstone aquifer characterized by porous flow. At both field sites, ¹⁴C analyses of the DOC provide additional information on the ground-water age. At the Stripa site the DIC from the recharge area

Antarctic seabirds including Adelie penguins (Pygoscelis adeliae), south polar skuas (Catharacta maccormicki), southern giant petrels (Macronectes gigantus) are high trophic level predators that accumulate persistent organic pollutants (POPs) present in the food webs in which they forage. Little is known about the levels of POPs in some Antarctic organisms (e.g. southern giant petrels), as well as the long-term trends of POPs in the Antarctic ecosystem. Samples from all three seabird species were collected post mortem, including eggs, from the Western Antarctic Peninsula (WAP) and in the Ross

Abstract:

Oceans store 685 Pg of organic carbon of which 662 Pg are in a dissolved form. The diversity of compounds that make up the dissolved organic matter (DOM) pool and the low concentration of each compound make the chemical characterization of this material a difficult task. For that reason, less than 11% of the oceanic DOM has been identified. A variable fraction of the DOM ¿between 20% in the open ocean and 70% in coastal areas- absorbs UV and visible radiation and it is known as coloured DOM (CDOM). A sub-fraction of the CDOM emits the absorbed radiation as fluorescence, although with a low qua

For perhaps eleven months of the year, surface water flow in the Santa Cruz River consists entirely of wastewater effluent from the Roger Road Wastewater Treatment Plant (RRWTP) and the Ina Road Water Pollution Control Facility (IRWPCF). Like other conventional plants that treat primarily domestic wastewater, effluents from the RRWTP and IRWPCF contain numerous trace organic contaminants--an unintended consequence of our reliance on water to carry waste from points of generation to central treatment facilities.
