In this study, 1228 urine samples were collected from different centres in Zimbabwe and were analysed for aflatoxin contamination. The urine samples were extracted with chloroform and analysed by thin layer chromatography and high-performance liquid chromatography. The most commonly observed contaminant was aflatoxin M1, at an average concentration of 4.2 ng/ml of urine. Although the national average of urine samples contaminated was 4.3%, there were areas in which up to 10% of the urine samples were contaminated.
在本研究中，从津巴布韦不同中心收集了1228份尿液样本，并对其黄曲霉毒素污染情况进行了分析。尿液样本用氯仿提取，然后通过薄层色谱法和高效液相色谱法进行分析。最常检测到的污染物是黄曲霉毒素M1，尿液中的平均浓度为4.2纳克/毫升。尽管受污染尿液样本的全国平均比例为4.3%，但有些地区高达10%的尿液样本受到了污染。
