This simulated field study investigated patterns of spray deposition on the clothing of lawn care applicators using a tank truck and handheld spray gun. The purpose was to provide a basis for designing a protective garment for lawn care specialists. The influence of flow rate and experience level of applicators on spray deposition was studied. FD&C Blue #1 dye was sprayed simultaneously by novice and experienced applicators in timed walks. There were four replications at full and at reduced flow rates. Spray garments were cut into 23 pieces representing body parts. Dye was recovered using four rinses of distilled water and analyzed by standard spectrophotometric techniques. Significantly more dye was deposited on the lower portion of the body, both front and back legs, than on other body parts. The amount on the lower legs accounted for 59% of the total, while hands accounted for 28%. There was a tendency for experienced applicators to have more dye on their clothing than the novice applicators. The amount of dye deposition did not differ significantly with flow rate. The findings provide a basis for designing clothing and developing recommendations to improve protection for lawn care specialists.
这项模拟实地研究使用一辆油罐车和手持式喷枪，调查了草坪护理施药人员衣物上的喷雾沉积模式。目的是为设计草坪护理专家的防护服提供依据。研究了施药人员的流速和经验水平对喷雾沉积的影响。新手和经验丰富的施药人员在定时行走过程中同时喷洒FD&C蓝色#1染料。在全流速和降低流速下各有四次重复。将喷雾服装剪成代表身体部位的23块。使用四次蒸馏水冲洗回收染料，并通过标准分光光度技术进行分析。沉积在身体下部，即前腿和后腿上的染料明显多于身体其他部位。小腿上的染料量占总量的59%，而手部占28%。经验丰富的施药人员衣物上的染料往往比新手施药人员更多。染料沉积量在流速方面没有显著差异。这些发现为设计服装和制定建议以改善对草坪护理专家的防护提供了依据。
