Uptake and excretion of total arsenic from monosodium methanearsonate (MSMA) in workers who applied the herbicide was followed during the spraying season. Urine, blood, and hair samples were collected and air samples were taken from the workers' breathing zone. Arsenic concentrations in air samples ranged from 0.001-1.086 micrograms/m3. Blood and urine arsenic values ranged from 0.0-0.2 mg/L and 0.002-1.725 mg/L, respectively. The geometric mean arsenic concentration in urine increased during the week but returned to base levels on weekends. Hair arsenic concentrations ranged from 0.02-358.0 mg/kg, increased during the spraying season, and returned to pre-season levels once herbicide application ceased. Three workers had higher than normal pre-exposure hair values. However, only one of the three workers had consistently above normal values throughout the study period.
在喷洒季节对使用除草剂甲胂酸钠（MSMA）的工人体内总砷的吸收和排泄情况进行了跟踪。收集了尿液、血液和头发样本，并从工人呼吸区域采集了空气样本。空气样本中的砷浓度范围为0.001 - 1.086微克/立方米。血液和尿液中的砷值分别为0.0 - 0.2毫克/升和0.002 - 1.725毫克/升。尿液中砷的几何平均浓度在一周内升高，但在周末恢复到基线水平。头发中的砷浓度范围为0.02 - 358.0毫克/千克，在喷洒季节升高，一旦停止使用除草剂就恢复到季节前水平。三名工人的暴露前头发砷值高于正常水平。然而，在整个研究期间，这三名工人中只有一人的值一直高于正常水平。
