【目的】:对于在职业上不接触锰的一般健康人的毛发、尿、血液中的锰含量,一年内每月进行一次测定,观察其个人的变动情况。【方法】: 样品采取:样品采取时问为1975年12月～1977年2月,受检者男女共计13例,在理发时采取头发,血液和尿标本。血液·尿中锰含量测定:用硝酸-高氯酸分解后,采用5％DDTC-乙基醋酸抽出的原子吸光法。毛发中锰含量测定:用乙醚洗净,再用硝酸-高氯酸分解后,用直接原子吸光法测定。
【Objective】: For the manganese content in hair, urine and blood of general healthy people who are not exposed to manganese in industry, the monthly measurement should be conducted within one year to observe the changes of the individuals. 【Method】: Sample taken: The sample taken from December 1975 to February 1977 asked a total of 13 men and women subjects, hair, blood and urine samples were taken at the haircut. Determination of manganese in blood and urine: Atomic absorption after extraction with 5% DDTC-ethyl acetate after decomposition with nitric acid-perchloric acid. Determination of manganese content in hair: washed with ether, and then nitric acid - perchloric acid decomposition, by direct atomic absorption spectrophotometry.
