对某炭素厂职业人群健康调查结果表明,煤焦沥青烟接触者皮肤损害症征、神衰综合征、呼吸系统症状及女职工的妇科疾病检出率均显著增高。与非接触者比较,这些暴露人群外周血T淋巴细胞显著减少,且呈现随沥青烟接触强度的增高及接触时间的延长而逐渐减少的趋势,据此,可以推断煤焦沥青烟除引起一般健康危害外,还可能影响这些职业接触人群的细胞免疫功能。
The results of health survey of occupational groups in a carbon factory showed that the detection rate of skin damage, Shen Syndrome, respiratory symptoms and gynecological diseases among female employees were significantly higher. Compared with non-contact group, the T lymphocytes in peripheral blood of these exposed groups decreased significantly, and showed a trend of decreasing gradually with the increase of contact intensity of bitumen smoke and prolongation of contact time. Based on this, it was concluded that addition of coal tar pitch smoke caused general health Harm, but also may affect the cellular immunity of these occupational exposure groups.
