Abstract
Selenium has been recognized as an important element from the perspective of human health and environmental geochemistry because it is either essential or toxic depending on its concentration and chemical form. The present work proposes a method for the determination of the total selenium and inorganic selenium species in wine samples using high performance liquid chromatography-inductively coupled plasma-mass spectrometry detection (HPLC-ICP-MS). Wine samples were collected from shops in Beijing. Selenium was found in all these samples, with the concentration of total selenium ranging from 7.0 to 94.0 ng mL−1. Inorganic selenium species in some wine samples were detected, ranging from 1.7 to 8.5 ng mL−1 for Se (IV) and 1.8 to 14.7 ng mL−1 for Se (VI). The concentration of Se (VI) compound in two samples was more than 10 ng mL−1, and represents a potential danger for the health of people who consume these alcoholic beverages.
