采集陕西省榆林市大骨节病病区蟒坑村，马家兔村及非病区长海则村和陕西省彬县大骨节病病区先锋村、韩家村的饮用水各２００ Ｌ，经ＸＡＤ７ 高效吸附树脂富集，甲醇丙酮洗脱后，采用色谱／质谱／红外光谱／计算机联机分析鉴定。病区水样共检出了１２ 种６ 类有机物，其中烷基、羟基二氢萘和临苯二甲酸酯均属含苯环的对人和动物有害的有机物，它们在病区水样有机物中的相对丰度均大于７４％ 。非病区水样检出了７ 种５ 类有机物，其中对人和动物有害的含苯环化合物在有机物中的相对丰度为３３％ ，与病区形成显著性差异。病区水样的红外光谱中特殊强吸收峰为１１００ ｃｍ － １、１６３０ ｃｍ － １和８５０ ｃｍ － １，主要是样品中含芳香烃、醇类和酰胺类化合物，而非病区水样的该吸收峰相对很低，形成显著差异。提示饮水中含苯环有机物（无论是芳香烃或者是烷基苯酚）可能是致大骨节病的主要有机物
The collection of drinking water 200 kilograms per kilogram of drinking water in the village of Kashin-Beck, Yasukuni Mabu Village and Changhai Village of non-ward and the Kashin-Beck disease area of Binxian County in Shaanxi Province were collected by XAD 7 efficient adsorption resin enrichment, methanol - acetone elution, using chromatography / mass spectrometry / infrared spectroscopy / computer analysis identified. A total of 12 species of 6 organic compounds were identified in ward water samples. Among them, alkyl, hydroxy-dihydronaphthalene and phthalates are all benzene and benzene-containing organism harmful to humans and animals. The relative abundance of organic matter are greater than 74%. Non-ward water samples detected seven kinds of five kinds of organic matter, of which human and animal harmful benzene-containing compounds in the relative abundance of organic matter was 33%, and the ward formed a significant difference. The special strong absorption peaks in the infrared spectrum of water samples in the ward are 1100 cm - 1, 1630 cm - 1 and 850 cm - 1, mainly containing aromatics, alcohols and amides in the sample, but not in the ward The absorption peak is relatively low, forming a significant difference. Prompt drinking water containing benzene ring organics (whether aromatic or alkylphenol) may be the main cause of KBD disease
