为了解某电镀厂镀铬车间职业危害情况,对该车间进行了现场卫生学调查,测定车间空气中三氧化铬浓度,并对车间90名作业工人进行职业健康检查。结果显示,镀铬车间空气中三氧化铬浓度符合国家职业卫生标准;临床检查发现,铬作业工人鼻咽部自觉症状如鼻塞、流涕、鼻衄、鼻灼痛、嗅觉减退和鼻部异常体征如鼻黏膜充血、鼻中隔黏膜糜烂、鼻中隔黏膜溃疡、鼻中隔穿孔的检出率与对照组比较,差异有统计学意义(P<0.05或P<0.01);工龄<10 a与≥10 a的2个工龄段,铬鼻病患病率比较,差异有统计学意义(P<0.01)。提示,长期接触低浓度铬对作业工人鼻部损害较明显,不容忽视,应积极采取措施进行综合防治。
In order to understand the occupational hazards of a chrome plating plant in an electroplating factory, an on-site hygiene investigation was conducted on the workshop to determine the concentration of chromium trioxide in the air of the workshop and 90 occupational health workers in the workshop were inspected for occupational health. The results showed that the concentration of chromium trioxide in the air of chrome-plated workshop accorded with national occupational health standards. The clinical examination found that the nasopharyngeal subjective symptoms of chromium workers such as stuffy nose, runny nose, epistaxis, nasal burning, hyposmia and nasal abnormal signs Nasal mucosal erosion, mucosal erosion of the nasal septum, mucosal ulcer of the nasal septum and perforation of the nasal septum compared with the control group, the difference was statistically significant (P <0.05 or P <0.01); 2 years of service <10 years and ≥10 years Section, the prevalence of chromium rhinopathy, the difference was statistically significant (P <0.01). Tip, long-term exposure to low concentrations of chromium on the nose damage workers more obvious, can not be ignored, should take active measures to carry out comprehensive prevention and treatment.
