The no-observable effect level (NOEL) for toxicity of beryllium was 0.2mg/L in rats, which was determined by tests of acute intoxication, chronic intoxication accumulation effects carcinogenesis, teratogenesis and mutagenesis. A safety factor of 1,000 was suggested for establishment of water quality standard of beryllium, because a marked accumulation of the metal was found in the tissues of rats following prolonged feeding and granulation tissue was formed in the lungs of these rats. Therefore, 0.0002 mg/L was recommended as a potable water quality standard of beryllium.
