【摘要】目的：探讨与分析长期低剂量苯及苯系物接触人群的肝脾超声异常情况。方法：采用回顾性研究方法，选取2019年1月—2020年1月在本单位门诊部进行职业健康检查的393例长期低剂量苯及苯系物接触人员作为接触组，同期选择在本单位门诊部进行职业健康检查的357例不接触化学毒物人群作为对照组，所有人群都给予腹部超声，记录肝脏与脾脏损害情况。结果：接触组的超声异常总检出率为44.27%，明显高于对照组的21.01%，差异有统计学意义(P<0.05)；接触组脂肪肝检出率为31.04%，明显高于对照组的14.57%，差异有统计学意义(P<0.05)；接触组肝实质回声增粗检出率为6.36%，明显高于对照组的0.84%，差异有统计学意义(P<0.05)；两组肝血管瘤、肝囊肿及脾肿大检出率对比差异均无统计学意义(P>0.05)。结论：长期低剂量接触苯及苯系物会对人群的肝脏产生损害，尤其增加了脂肪肝、肝实质回声增粗等疾病的发生率，要积极进行职业卫生防护，以保障接触人群健康。
