Safety
  • Treatment: EYES: irrigate opened eyes for several minutes under running water. INGESTION: do not induce vomiting. Rinse mouth with water (never give anything by mouth to an unconscious person). Seek immediate medical advice. SKIN: should be treated immediately by rinsing the affected parts in cold running water for at least 15 minutes, followed by thorough washing with soap and water. If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. INHALATION: supply fresh air. If required provide artificial respiration.

  • Toxicity summary: Selenium readily substitutes for sulfur in biomolecules and in many biochemical reactions, especially when the concentration of selenium is high and the concentration of sulfur is low. Inactivation of the sulfhydryl enzymes necessary for oxidative reactions in cellular respiration, through effects on mitochondrial and microsomal electron transport, might contribute to acute selenium toxicity. Selenomethionine (a common organic selenium compound) also appears to randomly substitute for methionine in protein synthesis. This substitution may affect the structure and functionability of the protein, for example, by altering disulfide bridges. Inorganic forms of selenium appear to react with tissue thiols by redox catalysis, resulting in formation of reactive oxygen species and causing damage...

  • OSHA Standards: 允许暴露限值:8小时时间加权平均值:0.2 mg/m³。/硒化合物(以Se计)/
  • Cleanup Methods: SRP:来自污染物抑制、防护服/设备清洁或污染地点的废水应被收集并评估主体化学物质或分解产物的浓度。浓度应低于适用的环境排放或处置标准。或者,只有在经过主管部门审查并确保不会发生"穿透"违规的情况下,才允许进行预处理和/或排放到许可的废水处理设施。应适当考虑修复工人的暴露(吸入、皮肤接触和摄入)以及在处理、转移和处置过程中的命运。如果不以这种方式管理化学品,则必须根据EPA 40 CFR第261部分进行评估,特别是...
