用兔肺泡巨噬细胞测试系统，以国产标准石英（Ｑ．Ｓ）为对照，选用细胞半数致死浓度（ＬＣ５０）、乳酸脱氢酶（ＬＤＨ）活性等指标，研究了ＧＢＷ０４１０１—ＧＢＷ０４１０５（Ｎｏ．１—Ｎｏ．５）５种标准铀矿样粉的体外细胞毒性。结果表明：国产标准石英毒性最强，１号和２号铀矿粉次之，３号和５号铀矿粉毒性较弱，４号铀矿粉毒性最弱。该工作可为定量评价粉尘样品的细胞毒性提供简便的方法。
Using rabbit alveolar macrophages test system, domestic standard quartz (Q.S) as a control, selected by the cell half lethal concentration (LC50), lactate dehydrogenase (LDH) activity and other indicators studied GBW04101-GBW04105 (No. In vitro cytotoxicity of five standard uranium ore samples. The results show that the domestic standard quartz is the most toxic, followed by the No.1 and No.2 uranium ore powder, the No.3 and No.5 uranium ore powder weaker and the No.4 uranium ore powder weakest. This work provides an easy way to quantitatively evaluate the cytotoxicity of dust samples.
