The investigation on 316 samples of urine from persons that are not professionally subject to the action of chromium or its compounds, demonstrated the following: - chromium is absent in the 8% of tested people; - average chromium concentration is 6.6 micrograms/l; - maximum chromium concentration is 36.6 micrograms/l. The average chromium concentration with regard to tested people living in the districts of Bergamo, Bolzano and La Spezia (4.21 - 4.16 - and 5.32 micrograms/l respectively) is 40% lower than chromium concentration observed in people living in the districts of Agrigento and Milan. The high rate of chromium elimination in people living in Milan (10,39 micrograms/l) depend upon the high chromium concentration in drinking water of this city (10.40 micrograms/l). In the 78% of urine samples a chromium concentration was found corresponding to or lower than 10 micrograms/l.
对316份非职业接触铬或其化合物人员的尿液样本进行的调查显示如下：- 8%的受测人员尿液中未检测到铬；- 铬的平均浓度为6.6微克/升；- 铬的最高浓度为36.6微克/升。居住在贝加莫、博尔扎诺和拉斯佩齐亚地区的受测人员的铬平均浓度（分别为4.21 - 4.16 - 和5.32微克/升）比居住在阿格里真托和米兰地区的人员的铬浓度低40%。居住在米兰的人员铬的高排出率（10.39微克/升）取决于该市饮用水中铬的高浓度（10.40微克/升）。在78%的尿液样本中，发现铬浓度等于或低于10微克/升。
