Abstract. This study was specifically aimed to determine the levels of beryllium in environmental samples near the vicinity of the beryllium metal plant (BMP). Air particulate samples collected at the BMP site, in the non-monsoon and monsoon seasons, showed an average beryllium concentration of 0.3 and 0.1 ng m −3 …
Beryllium (Be) is a silver-white and very light metal. It has a very high melting point at 2349 °F (1287 °C). It is found in nature primarily as bertrandite, which is mined in Utah, or as beryl. The combination of its lightweight and high melting point makes it valuable for making metal alloys which are used in electronic and electrical ...
