Biogeochemical cycle of atmospheric Selenium
Selenium (Se) is an essential micronutrient for human health; however, the recommended dietary intake is narrow. In fact, both deficiencies and surplus can cause disease and illness. The atmospheric component of selenium’s biogeochemical cycle is of particular importance, as it can help identify agricultural soils that may be at risk for Se-deficiency.
Currently, members of the NBD group are utilizing Se concentration time series of long term sites from the Interagency Monitoring of Protected Visual Environments (IMPROVE) Network and National Air Pollution Surveillance (NAPS) Program to ascertain temporal and spatial variability of Se across the United States and Canada.
