土壤样本于2005年5月27日至10月28日期间在日本秋田县由利本庄市采集。二嗪农是一种广泛使用的有机磷杀虫剂，检测到浓度很高。分析技术的最新进展使得能够通过测量二嗪农的 13C 同位素比来识别高含量二嗪农的来源。对主要在秋田县使用的八种二嗪农产品进行了分析。结果表明，二嗪农产品的同位素比范围为-31.25±4.071/2～-21.67±2.911/2，土壤样品中二嗪农的同位素比为-24.20±1.231/2。
Soil samples were collected between May 27 and October 28, 2005, at sites in Yurihonjo City, Akita Prefecture, Japan. Diazinon, an extensively used organophosphate insecticide, was detected in high concentrations. Recent advances in analytical techniques enabled identification of the source of the high levels of diazinon by measuring the 13C isotope ratio of diazinon. Eight diazinon products primarily used in Akita Prefecture were analyzed. The results show that the isotope ratio of the diazinon products ranged from -31.25 +/- 4.071/2 to -21.67 +/- 2.911/2, and the isotope ratio of the diazinon in the soil samples was -24.20 +/- 1.231/2.
