An Anaerobic Biosensor Assay for the Detection of Mercury and Cadmium
Published on: December 17, 2018
Abstract:
Among a wide spectrum of heavy metals, mercury is one of the most toxic ones that have a negative effect. The studies of hydrocoles have ascertained a certain association of the fish content of mercury with the pollution of water spaces. The content of mercury in finished fish products can be reduced, by correctly choosing manufacturing operations.

01:27The Periodic Table and Organismal Elements
Elements are the smallest units of matter that cannot be broken down further by chemical processes. There are 118 known elements, but not all of these are naturally occurring, and only a few of them are essential for life. Living matter is composed primarily of carbon, nitrogen, hydrogen, and oxygen, with smaller amounts of other elements like calcium, phosphorus, potassium, and sulfur. Other elements are also necessary for life but only in trace amounts.
