The data presented in this paper show statistically significant dose response relations between cumulative exposure to benzene (ppm-months) and mortality from both all lymphopoietic cancer combined and leukaemia. Chemical workers with a cumulative exposure to benzene of at least 720 ppm-months experienced a relative risk of 3.93 for lymphatic and haematopoietic cancer when compared with workers with no occupational exposure. The dose response relation between cumulative exposure and non-Hodgkin's lymphopoietic cancer was of borderline statistical significance (p = 0.06). No dose response relation was detected for any other causes of death.
本文所呈现的数据表明,苯的累积暴露量(ppm-月)与所有淋巴造血系统癌症合并死亡率以及白血病死亡率之间存在具有统计学意义的剂量反应关系。累积接触苯至少达720 ppm-月的化学工人,与无职业暴露的工人相比,患淋巴和造血系统癌症的相对风险为3.93。累积暴露与非霍奇金淋巴造血系统癌症之间的剂量反应关系具有临界统计学意义(p = 0.06)。未检测到其他任何死因的剂量反应关系。
