A small number of trace elements, such as selenium, are neither metals nor radionuclides. Selenium occurs naturally in sedimentary rocks, shales, coal and phosphate deposits, and soils. Application of irrigation water, which contains dissolved oxygen, can caused selenium to be released from sediment into groundwater, particularly in arid areas. COVID Resources.

The primary objective was to provide students and professionals with a comprehensive book about many important aspects of trace elements in the environment. The present edition follows a similar format, but includes new chapters. Black copper consists of an impure form of copper produced by smelting oxidised copper ores or impure scrap, usually in a blast furnace.
