	abstract = {The Giant Mine began gold production in Yellowknife, North West Territories, Canada, in 1948. Soon after this it was decided to store the arsenic trioxide dust from the smelter underground. The current situation is that the mine has now ceased operations leaving 260,000 tons of 78\% by weight arsenic trioxide dust stored in 15 underground chambers. The first part of the talk will outline the management options that include leaving the dust in place or removing it to the surface where further processing or stabilizing would be required. The second part addresses the approach taken to assess risk associated with surface soil contamination from mining activities. Soils from Yellowknife were differentiated according to type and organic carbon content, and subjected to an extraction system modeling the human gastro-intestinal system. The solubility, or bioaccessibility, of arsenic in soils thus obtained were then used to estimate risk from human exposure to these soils. The incorporation of bioaccessibility allows more realistic estimations of risk to be made and, in turn, aids in the development of cost-effective cleanup options.},

	abstract = {The arsC gene is responsible for the first step in arsenate biotransformation encoding the enzyme arsenate reductase. The quantitative real-time PCR method was developed to quantify the abundance of the arsC genes in environmental samples contaminated with arsenic. Two sets of primers that showed high specificity for the target arsC gene were designed based on consensus sequences from 13 bacterial species. The arsC gene was used as an external standard instead of total DNA in the calibration curve for real-time PCR, which was linear over six orders of magnitude and the detection limit was estimated to be about three copies of the gene. Soil samples from arsenic contaminated sites were screened for arsC genes by using PCR and showed the presence of this gene. The copy numbers of the gene ranging from 0.88 x 10(4) to 1.56 x 10(5) per ng total DNA were found in eight arsenic contaminated samples. Soil samples from a bioreactor containing pulp mill biomass and high concentration of arsenate showed a tenfold higher count of arsC gene copies than soil samples collected underground from an arsenic-rich gold mine.

	abstract = {Mycobacterium neoaurum demethylates both methylarsonic acid and methylarsonous acid to mixtures of arsenate and arsenite. After 28 days of incubation, the yields of inorganic arsenic were 27\% from arsenate and 43\% from arsenite. A time study of the demethylation of methylarsonic acid by M. neoaurum showed that demethylation occurs rapidly during the growth and stationary phases of the bacterium, and indicates that MMA(V) is reductively demethylated to arsenite.

	abstract = {Microorganisms which are able to degrade phenanthrene and pyrene were isolated from both seawater and sediment samples collected from a polycyclic aromatic hydrocarbon (PAH) polluted environment, Kitimat Arm, British Columbia, Canada. Four strains from a seawater culture were isolated and examined. No additional PAH induction was necessary in the enrichment process, indicating that these PAH degrading microorganisms are previously exposed to PAHs in the environment under study. Microorganisms enriched with phenanthrene as the sole carbon and energy source also degraded pyrene readily. A metabolite, pyrene cis-4,5-dihydrodiol was observed from pyrene degradation, and this metabolite was further degraded after pyrene was utilized by the microorganisms.},
