414名镍钴作业者与100名非镍钴作业者进行对照研究,镍钴作业空气中镍钴污染比对照组分别高2.7～18倍和3.69～11.1倍。尿镍发镍,尿钴发钴也比对照组明显高,有显著性差异,且与镍钴作业空气中的镍钴含量呈明显正相关。镍钴作业者与对照组相比,角膜缘色素沉着、结膜炎、晶体混浊均有明显增高并有非常显著性差异。晶体混浊随镍钴指数的增高而增多,呈正相关(r=0.6339)。镍钴对晶体的损害是较轻的混浊,对视力无明显影响。
A total of 414 nickel and cobalt operators compared with 100 non-nickel and cobalt operators. Nickel and cobalt contamination in nickel and cobalt were 2.7 to 18 and 3.69 to 11.1 times higher than those in the control respectively. Nickel nickel, cobalt cobalt hair cobalt than the control group was significantly higher, with significant differences, and nickel and cobalt air in the nickel and cobalt content was positively correlated. Compared with the control group, the operators of nickel and cobalt showed significantly increased corneal hyperpigmentation, conjunctivitis, and crystal opacity with very significant differences. Crystal opacity increased with increasing nickel-cobalt index, showing a positive correlation (r = 0.6339). Nickel and cobalt damage to the crystal is lighter turbidity, no significant effect on visual acuity.
