(一)环境中铍铍(Be)是40多种常见矿物中的一种基本或次要成分。金属工业和动力发电厂的排出物以及工业废水和城市污水中,铍浓度高达18～21 mg/m~3(IARC,1980)。海水含铍量不高(0.0006 mg/m~3),而淡水中的铍浓度可达0.3 mg/m~3。陆地植物平均含被量低于0.1mg/kg;但Peterson等(1981)发现有些植物含铍量达到10 mg/kg或甚至高达100 mg/kg。空气中铍的自然本底浓度约为0.1 ng/m~3。巴西、阿根廷、印度、苏联、非洲国家和
(A) Beryllium (Be) is one of the more than 40 common minerals in the environment. Beryllium concentrations of up to 18-21 mg / m 3 (IARC, 1980) were found in effluents from metal and power plants as well as from industrial and municipal wastewater. The beryllium content in seawater is not high (0.0006 mg / m ~ 3), while the concentration of beryllium in freshwater can reach 0.3 mg / m ~ 3. On average, terrestrial plants contain less than 0.1 mg / kg; however, Peterson et al. (1981) found that some plants contain beryllium up to 10 mg / kg or even up to 100 mg / kg. The natural background concentration of beryllium in the air is about 0.1 ng / m3. Brazil, Argentina, India, the Soviet Union, African countries and
