调查了20名接触石油产品(清洗油罐时)的工人(油罐清洁工)的嗅觉。参照对象为上班族和看守人(N=20+20)。他们在性别、年龄和吸烟习惯方面都是匹配的。气味检测阈值和四种气味刺激物吡啶、二甲基二硫化物(DMDS)、正丁醇和取暖油蒸气(取暖油的气相)加热到+40度时的气味感知强度。C)，确定了它们的存在。结果表明，油罐清洗剂对正丁醇和石油蒸汽的绝对气味阈值高于参照物。罐体清洁剂和参照物的心理物理功能对于所有被测试物质的气味强度是不同的。坦克清洁工表现出一种类似于听力损失的气味缺陷，即对强刺激的正常感觉，但对弱刺激的感觉受损。这种气味缺陷因此被称为“气味强度招募”，在油罐清洁工中，似乎与职业接触石油蒸气有关。
The olfactory perception of 20 men (tank cleaners) exposed to petroleum products (while cleaning oil tanks) was examined. Office workers and watchmen were used as referents (N = 20 + 20). They were matched with regard to sex, age, and smoking habits. Odor detection thresholds and the perceived odor intensity of four odorous stimuli, pyridine, dimethyl disulfide (DMDS), n-butanol, and heating oil vapor (gas phase of heating oil heated to + 40.degree. C), were determined. The results suggested that the tank cleaners had higher absolute odor thresholds for n-butanol and oil vapor than the referents. The psychophysical function of the tank cleaners and referents differed for all the tested substances in respect to odor intensity. The tank cleaners displayed an odor deficit analogous to the hearing loss known as "loudness recruitment," ie, normal perception of strong stimuli but impaired perception of weak stimuli. This odor deficit was therefore named "odor intensity recruitment" and seems, in tank cleaners, to be associated with occupational exposure to oil vapor.
