目的为进一步研究噪声对血液系统的影响，对接触噪声的工人进行了调查。方法采指尖血进行血细胞计数及血红蛋白测定，并测定作业现场噪声强度。结果接触噪声强度平均为８６ｄＢ（Ａ）的工人血红蛋白降低的阳性率（１３．３％）明显高于对照组（１．７％），差异有非常显著意义；１０年工龄组工人血红蛋白降低的阳性率（２０．４％）显著高于１年工龄组（５．３％），差异有显著意义；噪声组工人白细胞总数（５．６７×１０９／Ｌ）减少，主要为中性粒细胞减少（０．５７５），而淋巴细胞０．３６３，单核细胞０．０４５，嗜酸细胞０．０１及嗜碱细胞数（０．０１）明显增高，与对照组比较，差异均有非常显著意义或有显著意义，１０年工龄组工人中性粒细胞降低和淋巴细胞相对增高与１年工龄组有显著性差异。结论长期接触噪声对血液系统确有一定影响，且以１０年工龄组工人尤为明显。
Objectives To further investigate the effects of noise on the blood system, workers exposed to noise were investigated. Methods Finger blood was taken for blood cell count and hemoglobin determination, and the intensity of noise at work site was measured. Results The positive rate of hemoglobin decrease (13.3%) was significantly higher in workers with an average exposure noise of 86dB (A) than that in control group (1.7%). The difference was significant The rate (20.4%) was significantly higher than that in the 1-year group (5.3%), and the difference was significant. The total number of white blood cells (5.67 × 109 / L) in the noise group decreased mainly for neutropenia 0.575), while lymphocytes 0.363, monocytes 0.045, eosinophils 0.01 and basophils (0.01) were significantly increased compared with the control group, the differences were significant or Significantly, workers in the 10-year-old workers with neutropenia and relatively high levels of lymphocytes and 1-year age group were significantly different. Conclusion Long-term exposure to noise has some effect on the blood system, especially in the 10-year-old group of workers.
