目的 探讨磷化氢(PH_3)作业对工人健康的影响。方法 对某县的粮食管理所6个仓库空气中PH_3浓度进行测定和对PH_3作业人员体内钙磷代谢情况及其健康情况进行调查。结果 接触组血磷、血钙浓度均高于对照组(t值分别为5.182和2.666,P<0.01),差异有非常显著性,且作业工人体内血磷、血钙异常与工龄无关,接触组神经衰弱综合征、呼吸道和消化道的刺激症状发生率均显著高于对照组(P<0.05)。结论 从事PH_3作业可对工人的健康造成一定影响。
Objective To investigate the effect of phosphine (PH_3) on workers’ health. Methods The concentration of PH_3 in the air of 6 warehouses in a county’s grain management station was measured and the metabolism of calcium and phosphorus in PH_3 workers and their health were investigated. Results The levels of serum phosphorus and calcium in the exposure group were higher than those in the control group (t = 5.182 and 2.666, respectively, P <0.01). There was a significant difference between the two groups Neurasthenic syndrome, respiratory and gastrointestinal irritation symptoms were significantly higher than the control group (P <0.05). Conclusion PH_3 operations can have some impact on the health of workers.
