为了解某橡胶厂1,3-丁二烯(BD)作业人员的健康状况,选择该厂BD作业人员200名作为接触组,同厂不接触BD的锅炉工人和行政人员89名作为对照组,比较接触组和对照组血常规主要指标水平。结果表明,接触组肝功能与对照组比较,肝功能异常率差异无统计学意义(P>0.05);肝B超异常率(脂肪肝、肝血管瘤、肝囊肿和胆石症)差异无统计学意义(P>0.05)。此外,心电图、高血压、高血脂、肾和胆囊B超异常、尿血阳性和白细胞降低(低于4.0×109/L)发生率两组比较,差异均无统计学意义(P>0.05)。男性或者女性的白细胞、红细胞、血小板计数和红细胞压积接触组与对照组比较,差异无统计学意义(P>0.05),接触BD导致工人血红蛋白含量增高,男女工人均如此,男性更为明显。提示,长期接触低浓度BD,对身体各项指标的影响不大,但可引起血红蛋白含量升高,原因尚待探讨。
In order to understand the health condition of 1,3-butadiene (BD) workers in a rubber plant, 200 BD workers in the plant were selected as the contact group and 89 boiler workers and administrators without BD contact were taken as the control group. Compare the main indexes of blood routine in contact group and control group. The results showed that there was no significant difference in liver function abnormalities between the exposed group and the control group (P> 0.05). There was no significant difference in the abnormal rate of B-ultrasound (fatty liver, hepatic hemangioma, hepatic cyst and cholelithiasis) Significance (P> 0.05). In addition, there was no significant difference between the two groups in the incidence of electrocardiogram, hypertension, hyperlipemia, renal and gallbladder abnormalities, hematuria, and leukopenia (less than 4.0 × 109 / L) (P> 0.05). There was no significant difference in leucocyte, erythrocyte, platelet count, and hematocrit exposure between men and women and control group (P> 0.05). Exposure to BD resulted in an increase of hemoglobin in workers, both in male and female workers, and men were more obvious. Tip, long-term exposure to low concentrations of BD, the body of the indicators have little effect, but can cause hemoglobin levels, the reasons remain to be explored.
