Dose and Diet - Sources of Arsenic Intake in Mouse in Utero Exposure Scenarios.

In humans, early life exposure to inorganic arsenic is associated with adverse health effects. Inorganic arsenic in utero or in early postnatal life also produces adverse health effects in offspring of pregnant mice that consumed drinking water containing low part per billion levels of inorganic arsenic. Because aggregate exposure of pregnant mice to inorganic arsenic from both drinking water and food has not been fully evaluated in experimental studies, quantifying arsenic exposure of the developing mouse is problematic.

Nitarsone, Inorganic Arsenic, and Other Arsenic Species in Turkey Meat: Exposure and Risk Assessment Based on a 2014 U.S. Market Basket Sample.

Background: Use of nitarsone, an arsenic-based poultry drug, may result in dietary exposures to inorganic arsenic (iAs) and other arsenic species. Nitarsone was withdrawn from the U.S.

Determination of the trypanocidal drug melarsoprol and its conversion products in biological fluids with HPLC-ICPMS/ESMS.

Although melarsoprol, an organoarsenic compound, is widely used for the treatment of trypanosomiasis (human African sleeping sickness), very little is known about its fate in the human body, its active metabolites passing the blood-brain barrier and the mode of action. Previous pharmacological studies based on the determination of melarsoprol by HPLC-UV or by a bioassay method produced different results. We report a HPLC-ICPMS method suitable for determining melarsoprol and its metabolites in biological fluids.
