Sources, Fate, and Toxic Hazards of Oxygenated Polycyclic Aromatic Hydrocarbons (PAHs) at PAH- contaminated Sites
Abstract In this paper we show that oxygenated polycyclic aromatic hydrocarbons (oxy-PAHs) are important cocontaminants that should be taken into account during risk assessment and remediation ofExpand

Secular variation in carbon isotope ratios from Upper Proterozoic successions of Svalbard and East Greenland
Analyses of stratigraphically continuous suites of samples from Upper Proterozoic sedimentary successions of East Greenland, Spitsbergen and Nordaustlandet (Svalbard) provide an approximation to theExpand

Detailed review of transgenic rodent mutation assays.
Induced chromosomal and gene mutations play a role in carcinogenesis and may be involved in the production of birth defects and other disease conditions. While it is widely accepted that in vivoExpand

Identification and characterization of SnrA, an inducible oxygen-insensitive nitroreductase in Salmonella enterica serovar Typhimurium TA1535.
The biological activity of many nitrosubstituted compounds, many of which are produced commercially or have been identified as environmental contaminants, is dependent on metabolic activationExpand

Palaeoenvironment and carbon isotope stratigraphy of Upper Proterozoic carbonates of the Yangtze Platform
The δ13C values for Phanerozoic marine carbonates display secular trends, mainly in the range –1 to 2‰1. These have been interpreted as primary features reflecting changes in the carbon isotopeExpand

Melting of Gabbro (Quartz Eclogite) with Excess Water to 35 Kilobars, with Geological Applications
Crystalline, fine-grained, high-alumina olivine tholeiite with excess water was reacted in sealed platinum capsules in piston-cylinder apparatus between 10 and 35 kbar pressure. Runs were planned toExpand

Geochemical investigations of deep-seated rocks in the Australian shield
Medium to high pressure granulite facies rocks are relatively uncommon at the earth's surface and are probably formed at considerable depth in the continental crust. Low pressure granulite faciesExpand

Detection of induced male germline mutation: correlations and comparisons between traditional germline mutation assays, transgenic rodent assays and expanded simple tandem repeat instability assays.
Several rodent assays are capable of monitoring germline mutation. These include traditional assays, such as the dominant lethal (DL) assay, the morphological specific locus (SL) test and theExpand

Salmonella typhimurium mutagenicity tester strains that overexpress oxygen-insensitive nitroreductases nfsA and nfsB.
We have designed and constructed a series of plasmids that contain the major and/or minor Escherichia coli nitroreductase genes, nfsA and nfsB, in different combinations with R plasmid mucA/B genesExpand
