· Selenium as an element lies at a narrow boundary of micronutrient and toxicant due to its chronic health effects when consumed above 10 ppb. A minimum of 40 µg/day of selenium is, however, recommended to intake in a daily diet. However, its consumption beyond a permissible limit through consumption of contaminated water/food has adverse health effects. Thus, the selective detection of ...
