对接触红外辐射的167名炼钢工人进行了晶状体混浊的调查,结果显示,红外辐射可致炼钢工人晶状体混浊。其人(眼)检出率为37.1(32.0)％,与对照组的21.7(18.3)％比较P<0.05(P<0.01)。炼钢工人20岁组即出现晶体混浊,且与高龄组比较无显著性差异。为排除年龄影响,标化后混浊仍显著高于对照组(P<0.01);随工龄延长,晶状体混浊检出率随之增高。此外,炼钢工人组晶状体混浊形态除与对照组共有的点状、线条状外,还查见有蛛网状、放射状、片状及星状混浊。
Investigations of lens opacity by 167 steelmakers exposed to infrared radiation showed that infrared radiation caused turbidity in the steelmaker’s lens. The detection rate of human (eye) was 37.1 (32.0)%, P <0.05 compared with that of control group (21.7%) (P <0.01). The 20-year-old steelmaking workers showed crystal opacity and no significant difference compared with the senior group. To exclude the influence of age, the turbidity after standardization was still significantly higher than that of the control group (P <0.01). With the increase of service life, the detection rate of lens opacity increased. In addition, the group of workers in the steelmaking group had opacity, arachnoid, radiate, flaky and stellate turbidities in addition to the dot-shaped and the line-shaped common to the control group.
