汞是一種化學元素，俗稱水銀。在常溫下為液態物質，常被廣泛的使用在日光燈管、水銀電池、水銀溫度計、血壓計、燈泡或鍊金等工業上，然而，由於汞極易蒸發，故常會造成勞工與環境的危害。目前勞委會規定汞蒸氣作業環境空氣中之八小時平均容許濃度為每立方公尺0.05毫克。本案例為個案參與私人鍊金，且當時工作環境並未有個人呼吸防護及環境控制。在數小時之後，即開始有不適的症狀，而二天後身體發現有多處的紅疹。在血液與尿液檢查證實汞中毒後，便給予治療，而紅疹在數日之後即消失。本文的目的是希望藉此病例及文獻之回顧，能使基層醫師對汞的危害能進一步的了解。

Mercury is a metal that is in liquid form at the room temperature. It is commonly used in industry to make thermometers, barometers, manometers, sphygmomanometers, and gold extraction. However, due to the characteristic of high vapor pressure, mercury vapor can damage human body by poisoning via inhalation. The occupational exposure limits (OEL) for mercury vapor in Taiwan is 0.05 mg/m^3 TLV. The case presented in this paper is a 60-year-old male who participated in gold extraction by amalgamation with his friend. With no personal respirator protector and environment control available at that time, several uncomfortable symptoms developed after several hours. Skin rash occurred 2 days later and the mercury level in blood and urine were all high to confirm diagnosis of mercury intoxication. After chelator therapy, the skin rash disappeared. With this case and other relevant documents, this article intended to provide doctors with further knowledge on mercury intoxication.
