322-329. Two field-trials in Malaysian rubber plantations are described in which operators applied paraquat for weed control with hand-operated knapsack sprayers. The extent of systemic absorption was assessed by weekly estimation of urinary paraquat concentrations during and after a 12-week period of continuous spraying. Periodic medical examinations, including chest radiographs, were made before and during the trials and for some weeks afterwards. The conditions of continuous operation with paraquat were probably close to the extremes of exposure likely to occur in any agricultural operation, but the investigations have shown that ordinary care in personal hygiene is sufficient to prevent any hazard from surface injury or from systemic absorption.
322 - 329。本文描述了在马来西亚橡胶种植园进行的两项田间试验，试验中操作人员使用背负式手动喷雾器施用百草枯进行杂草控制。通过在连续喷洒12周期间及之后每周测定尿中百草枯浓度来评估全身吸收的程度。在试验前、试验期间以及之后的几周内进行了定期体检，包括胸部X光检查。使用百草枯连续作业的条件可能接近任何农业作业中可能出现的极端暴露情况，但调查表明，日常注意个人卫生足以防止因体表损伤或全身吸收而产生任何危害。
