镇江市某造纸企业噪声作业工人健康状况

Health status of workers exposed to noise in a papermaking enterprise of Zhenjiang City

目的调查造纸生产过程噪声对造纸作业人员身体健康的影响。方法选取镇江市某大型造纸企业,对其作业场所噪声强度进行监测;同时选择该企业接触噪声的1 717名作业人员作为观察组,其他单位410名行政管理人员作为对照组,对他们进行听力测定、血压、心电图等职业健康检查。对不同工龄接触噪声作业人员体检结果异常率进行统计分析。结果接触噪声作业人员高频听损率、语频听损率、高血压患病率和心电图异常率分别为22.6%、12.3%、10.4%、22.1%,均高于对照组的8.5%、4.6%、5.4%、16.3%,差异均有统计学意义(χ2值分别为41.1、5.6、9.7、6.7,均P<0.05)。结论该造纸生产企业噪声污染普遍存在。长期接触噪声对作业人员的听觉系统及心血管系统影响较大。因此,应对造纸行业的噪声危害采取切实有效的防范措施,以保护工人的健康。

[ Objective ] To investigate the influence of paper manufacturing noise to the health of the workers with exposure. [ Methods] The noise density of different work place was detected in a large papermaking enterprise. The papermaking workers who exposed to noise in the factory were selected as exposed group and some administration staffs in the other factory were recruited as control group. Their physical examination including audiometry, ECG and blood pressure. The abnormal rate of examination results between workers with different length of noise exposure was analyzed statistically. [ Results] The rate of high-frequency heating loss rate, speech frequency hearing loss rate, abnormal rate of hypertension and abnormal ECG in exposed group （22.6%, 12.3%, 10.4%, 22.1% respectively） was higher than those of control group（8.5%, 4.6%, 5.4%, 16.3% , respectively. There were significant differences （ all P 〈0.05 ）. [ Conclusion] Noise pollution is prevalent in the papermaking enterprise. The noise has great influence to the auditory system and cardiovascular system of workers. Therefore, it is necessary to take effective prevention measures in paper production industry to protect workers＇ health.
