为探讨丁二烯对肝脏的影响，对某公司橡胶厂丁苯、聚合、单体车间，长期接触低浓度丁二烯的４４名青年作业工人进行了肝脏Ｂ超和肝功能化验检查，并分别与本公司生产条件基本相同，不接触任何毒物的热电厂青年作业工人进行了比较，对长期接触低浓度丁二烯的青年作业工人进行了跟踪自身对比观察。结果显示，Ｂ超检查，观察组肝右叶最大斜径和肝右叶前后径与对照组比差异有显著性（Ｐ＜０．０５）；肝功能化验检查略高于对照组，但差异无显著性。观察组肝脏Ｂ超自身对比检查，４年后与４年前相比肝脏各径线均有所增大（Ｐ＜０．００１）。检查结果表明，长期接触低浓度丁二烯可能对肝脏有一定影响
In order to explore the impact of butadiene on the liver, 44 young workers exposed to butadiene, polymerization, monomer plant and long-term low-concentration butadiene in a rubber plant of a certain company were inspected for liver B-test and liver function test, respectively Compared with the young workers in the thermal power plant who are basically the same in production conditions and do not touch any poison, the young workers who have been exposed to low concentrations of butadiene for a long time are tracked and compared with each other. The results showed that there was a significant difference between the B-mode ultrasonography and the observation group in the maximum oblique diameter of the right lobe and the anteroposterior diameter of the right lobe (P <0.05), and the liver function test was slightly higher than that of the control group Significance. Liver biopsies in the observation group were compared with each other. After 4 years, all diameters of the liver were increased (P <0.001) compared with 4 years ago. Test results show that long-term exposure to low concentrations of butadiene may have some impact on the liver
