Arsenic is a widespread environmental contaminant whose toxicity depends on its valence and its chemical form. Arsenic species have been typically determined using high pressure liquid chromatography coupled to inductively coupled plasma mass spectrometry (HPLC-ICPMS), however ICPMS cannot...

Hydrotreating is the response to the necessity of a cleaner feed for downstream processes and reduced pollution. Hydrotreating catalysts are vital in this process; hence catalyst deactivation is a key issue. The principal objective of this research was the experimental study of hydrotreating...

An organoarsenic compound, 3-nitro-4-hydroxyphenyl arsenic acid (also known as Roxarsone), has been used as a feed additive. Roxarsone was approved by the Food and Drug Administration (FDA) to control diseases in poultry, and to improve weight gain, feed efficiency, and meat pigmentation....

We demonstrate the development of a real-time cell analysis (RTCA) platform for studying nanoparticle- and arsenic-induced cytotoxicity with potential applications to risk assessment, environmental toxicity monitoring, and drug development. RTCA is an impedance-based in vitro detection system...

Antimony is naturally occurring in the environment. The assessment of human exposure to environmental antimony is limited. This research focuses on the determination of antimony in water, beverages, and fruit. First, we explored whether there is a correlation between arsenic and antimony in...

The presence of arsenic in e-liquids of electronic cigarettes has rarely been studied and the few studies that have investigated the presence of arsenic have found either very low, or undetectable concentrations. Additionally, the individual species of arsenic have not been thoroughly explored...

Arsenic (As) concentration above the Health Canada and WHO drinking water guidelines of 10 µg L-1 in the Cold Lake area, Alberta is an issue of concern for environmental and human health. The source of groundwater As is ambiguous. This study was initiated to characterize the surficial deposits...

Arsenic is a proven human carcinogen and associated with a myriad of other adverse health effects. This metalloid is methylated in human liver to monomethylarsonic acid (MMAV), monomethylarsonous acid (MMAIII), dimethylarsinic acid (DMAV), and dimethylarsinous acid (DMAIII) and eliminated...

Arsenic is a worldwide environmental pollutant that is associated with skin and several types of internal cancers, such as liver, lung, kidney, urinary bladder, and prostate cancers. Recent reports revealed that organic arsenic metabolites, such as trimethylarsine oxide (TMAO), dimethylarsinic...

Industrial development of the Athabasca Bituminous Sands (ABS) in northern Alberta, Canada, has raised concerns that emissions of arsenic and selenium to the surrounding landscape and waterbodies have been increasing over time. To test this hypothesis, a comprehensive study of arsenic and...
