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５０４．４１／１０５．同对照组全癌发病率１４９．７６／１０５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７２１．６５／１０５，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４１８．９８／１０５，两者间没有明显差异（Ｐ＞０．０５）。说明皮毛尘可以引起癌病高发，且与生产过程中加入的各种化学物质没有明显关系，主要是皮毛尘的作用。
The survey found that the incidence of all cancers in contact with fur workers in five fur factories in North China was 504.41 / 105. Compared with the control group, the incidence of total cancer was 149.76 / 105, there was a significant difference (P <0.01). Among them, the incidence rate of dermatosis with simple contact dermatosis was 721.65 / 105. The incidence of dermatosis with chemical substances mixed with carcinogenic chemicals (including CrO3 with carcinogenicity) was 418.98 / 105, with no significant difference between the two (P> 0.05). Description fur dust can cause high incidence of cancer, and with the production process has no obvious relationship between the various chemicals, mainly the role of fur dust.
