A proportionate mortality ratio (PMR) analysis of 1071 deaths in pulp and paper mill workers in New Hampshire during 1975-85 showed an increase in cancers of the digestive tract and lymphopoietic tissues. A similar analysis of deaths for 452 timber cutters and loggers failed to show excess PMRs for cancers of these sites. Despite methodological constraints, these results suggest that one or more of the exposures experienced by pulp and paper mill workers may pose a significant carcinogenic risk. More definitive epidemiological studies are required to determine particular high risk processes or specific aetiological agents.
对1975年至1985年间新罕布什尔州纸浆和造纸厂工人的1071例死亡病例进行的比例死亡率(PMR)分析显示,消化道和淋巴造血组织癌症有所增加。对452名伐木工和伐木工人的死亡病例进行的类似分析未显示这些部位癌症的比例死亡率过高。尽管存在方法上的限制,但这些结果表明,纸浆和造纸厂工人接触的一种或多种物质可能构成重大致癌风险。需要更明确的流行病学研究来确定特定的高风险过程或特定的病因。
