Beryllium is found at low levels geologically in Canada, mostly in northern British Columbia and the Northwest Territories (CAREX ). Beryllium occurrences in Canada fall File Size: KB. Beryl occurrences in Canada are mostly associated with either Archean pegmatites in the Canadian Shield or Mesozoic/Cenozoic granitoids in the Cordilleran. The late Archean Superior and Slave provinces host several examples of rare-element (i.e., beryllium) bearing pegmatites (Breaks et al., ; Tomascak et al., ). This document contains a review of the chemical and physical properties of beryllium, the sources and emissions in Canada, the distribution and behaviour of beryllium in the environment and the toxicological effects of beryllium in humans and mammalian Size: KB. Back to Rocks and Minerals Articles Kathy Feick The mineral Beryl was known to a number of ancient societies. The element beryllium however, was not recognized until when French Scientist, Nicholas Louis Vauquelin discovered it as a component of beryl. This led to the element being named beryllium. It is also suspected that the word brilliance is probably derived from the.
Warning! Inhaling beryllium dust or fumes can be fatal. Beryllium is a confirmed human carcinogen. The critical effects of exposure to beryllium are lung cancer and berylliosis. The present ACGIH TLV (the legal exposure limit) for beryllium is only 2 micrograms of the element per cubic meter of inhaled air and is under review. Therefore. Aquamarine beryl from Zealand Station, Canada: a mineralogical and stable isotope study Kristy-Lee BEAL*, Beryllium is a relatively rare element in the Earth’s crust. Beryllium, chemical element that is the lightest member of the alkaline-earth metals of Group 2 of the periodic table. It is used in metallurgy as a hardening agent and in many outer space and nuclear applications. It is a steel-gray metal that is quite brittle at room g: Canada. Beryl Pit (Quadeville East mine), Lyndoch Township, Renfrew County, Ontario, Canada: The initial discovery of beryl on this property was by Miller in It was first opened in by T. B. Caldwell of Perth and pounds of beryl were obtained in The property was dormant.

Beryllium is a toxic bivalent element, steel gray, strong, light-weight, primarily used as hardening agent in alloys. Beryllium has one of the highest melting points of the light metals. It has excellent thermal conductivity, is nonmagnetic, it resists attack by concentrated nitric acid and at standard temperature and pressures. For readability purpose, only non-confidential use descriptors occurring in more than 5% of total occurrences are displayed. The described Product category (i.e. the products in which the substance may be used) may refer to uses as intermediate and under controlled conditions, for which there is no consumer exposure. More help is available here. Beryllium and beryllium compounds were considered by previous IARC Working Groups in , , , and (IARC, , , , ). Since that time, new data have become available, these have been incorporated in the Monograph, and taken into consideration in the present evaluation.
