    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. Reliable information about the coronavirus (COVID) is available from the World Health Organization (current situation, international travel).Numerous and frequently-updated resource results are available from this ’s WebJunction has pulled together information and resources to assist library staff as they consider how to handle . The Legnica copper smelter is a part of the mining and metallurgy complex founded in , which currently includes 4 mines, 3 ore enrichment plants and 3 smelters [16]. The complex has been producing approximately tons of copper annually, one.
