A survey was undertaken within four dairy farms in Al-Kharj area, Saudi Arabia, to measure the selenium (Se) content in the soil, alfalfa, and water samples. Selenium was determined by Inductively Coupled Plasma Atomic Emission Spectrometry. Selenium content in the studied soil samples was low, and, in some farms, the Se content of alfalfa approached that in the low-Se zone in China. This may be reflected in the dietary Se-intake level of the Saudi population with an increased risk for developing Se deficiency-associated diseases. We suggest that extensive surveys of the Se status should be carried out in Saudi Arabia. Moreover, Se supplementation of the soil may be advisable.
在沙特阿拉伯哈吉尔地区的四个奶牛场进行了一项调查，以测量土壤、苜蓿和水样中的硒（Se）含量。采用电感耦合等离子体原子发射光谱法测定硒含量。研究的土壤样品中硒含量较低，在一些农场，苜蓿中的硒含量接近中国低硒地区的水平。这可能反映在沙特人群的膳食硒摄入量水平上，增加了患硒缺乏相关疾病的风险。我们建议在沙特阿拉伯广泛开展硒状况调查。此外，对土壤进行硒补充可能是可取的。
