以和田市城区2014年采集的大气PM_(2.5)样品为实验对象,将0.1 g的PM_(2.5)样品膜与2-硫代巴比妥酸(0.2%)和三氯乙酸(20%)混合显色液反应,用可见光分光光度计测定反应产物的吸光度,通过正交实验来优化PM_(2.5)膜中丙二醛(MDA)的提取及测定条件,结果表明,在反应温度90℃、超声和加热时间40 min、显色剂用量为45 mL时,反应产物在532 nm处具有稳定的最大吸收峰。对和田市城区PM_(2.5)及MDA质量浓度的变化特征分析结果表明,和田市城区4个季节PM_(2.5)平均质量浓度由高到低顺序分别为春季(1 096.67±369.60)μg/m~3、夏季(1 016.16±708.00)μg/m~3、秋季(686.88±525.00)μg/m~3和冬季(214.54±94.70)μg/m~3。MDA平均质量浓度的变化范围为1.10～7.75 ng/m~3,其平均值最高为夏季(4.43±1.80)ng/m~3,最低为春季(1.42±0.60)ng/m~3,冬季与秋季相当,分别为(2.93±0.70)ng/m~3和(2.83±0.80)ng/m~3;最终,将PM_(2.5)膜中MDA的质量浓度与相应的TD_(30)(体外DNA氧化损伤达到30%的剂量)进行相关性分析得出,无论是全样还是水样的TD_(30)值均随MDA浓度的升高而呈降低的趋势。其中,全样与MDA质量浓度的相关性更为显著(r=-0.597,显著性P0.01)。
