皮毛尘作业工人职业癌发生特点的探讨

调查中国华北地区５个皮毛厂接触皮毛尘工人的全部癌发病率为５０４．４１／１０＾５。同对照组全癌发病率１４９．７６／１０＾５比较有非常显著差别（Ｐ＜０．０１）。其中单纯接触皮毛尘癌发率为７２１．６５／１０＾５，接触混有化学物质（包括有致癌性的ＣｒＯ３等化学物质）皮毛尘的癌发率为４１８．９８／１０＾５，两者间没有明显差异（Ｐ＞０．０５）。说明皮毛尘可以引起癌病变发，且与生产过程中加入的各种化学物质没有明

The Study on the Occurrence of Cancers in Workers Exposed to Fur dust

Cancer incidence of workers exposed to fur dust was studied in five fur processing factories.The results showed that the incidence of all cancers was 504.41/105.Concerning cancers in different sites,incidences of the cancer of digestive tract and respiratory tract were 329.81/105 and 126.10/105,respectively.The incidence of total cancers,digestive tract cancers and respiratory tract cancers were 149.76/105, 85.58/105 and 64.18/105,respectively in control group.There was significant difference for all cancers and digestive tract cancers between the fur dust group and controls(P<0.01; P<0.05)The incidences of all cancers in workers exposed to pure fur dust and to mixture fur dust were 721.65/105 and 418.98/105,respectively and there was no statistical significance.It was suggested the fur dust increased the risk of cancer incidence.
