摘要

選取高雄市47所牙科診所訪視其汞衛生環境，並收集47名牙醫師，8名牙科助手，以及29名對照組之晨尿以測定其含汞量；結果顯示牙科執業人員之尿汞濃度平均值為4.61μg／l，然其值仍在尿汞濃度正常值範圍內，且低於外國學者所發表的數值。在造成牙科執業人員不當吸入多量汞之因素中，以汞齊調拌方式及殘汞處理兩方面之不良習慣最應提出以求改進。

The use of amalgam in dentistry may cause mercury contamination to the dental professions. This study is to investigate this possibility from 47 dental clinics in Kaohsiung City, Taiwan. Morning urine of 47 dentists and 8 assistants and 29 individuals who worked in non-mercury environment were collected. Urinary mercury was determined with atomic absorption spectrophotometer (Type IL-751). Our results indicated that the average mercury concentration (4.61 μg/l) of the 55 dental professions are apparently
higher than those of 29 non-dental professions (2.41 μg/l), (t=2.73, p＜0.05). Our investigation also suggested two major factors causing mercury contamination in these dental clinics: the improper mixing of amalgam and poor treatment of residual mercury. Although the present results showed the average urinary mercury concentration of our dental professions is lower than that in other countries, recommendations for the correction of the above mentioned two bad factors should be implemented.
