Living with copper
Copper is one of a few elements that are essential for life. It is a part of a number of biological molecules. For example, some enzymes that are involved in respiration contain copper.

Copper is both good and bad for living things. At very low concentrations, it is useful. But when the concentration increases, it becomes toxic and interferes with cell metabolism.

In this electronic resource (e-source), we'll look at how copper is essential for life and how it can be used as a biocide.
