摘要
目的:探索苯酐(PA)的慢性职业危害和对人体内微量元素的影响。方法:劳动卫生学调查和对82名接触工人及对照组行医学检查。结果:长期接触较高浓度PA,鼻炎、皮炎发病率增高、哮喘加重,血清锌及特异性免疫球蛋白G水平增高;后者呈明显剂量-效应关系。结论:PA是一种致敏原,建议将特异性免疫球蛋白和血清锌作为PA慢性接触的一种生物监测指标。
Objective: To evaluate the chronic hazard of 0 phthalic anhydride(PA) and effect of trace elements. Methods: Investigate labour hygiene and medical examination for 82 workers compared with control. Results: Long term exposed to higher concentration of PA, the incidence of rhenitis and dermititis were increased,asthma exaggerated, serum zinc and specific immunoglabulin G were elevated; the later showed dose effect relationship. Conclusion: PA was an allergen, the specific immunoglobulin and serum zinc may choiced as an index of biological monitoring for chronic exposed to PA.
