长期接触低浓度氨工人肝功能的改变

Changes of liver function in workers long-term exposed to low-level ammonia

对长期接触低浓度氨工人血氨和血清ALT进行测定 ,以探讨长期接氨对肝功能的影响。结果表明长期低浓度氨接触可使肝功能出现轻微异常 ,脱离氨作业环境后 。

In order to study effect of long-term exposure to low-level ammonia on liver function in exposed workers,blood ammonia level and activities of serum alanine aminotransferase(ALT)were determined.Results showed that only mild liver dysfunction was found in the workers long-term exposed to low-level ammonia,which could be gradually recovered to normal after remove from their exposed position.
