摘　　要：根据全国多家实验室的监测数据,系统地研究了地表水中51种有机物的加标回收率质量控制水平,提出了两种概率下的质量控制指标。研究表明,51种有机物的实际样品加标回收率的控制范围比空白样品的加标回收率范围宽,大部分有机化合物的加标回收率可控制在60%～120%之间,个别化合物的回收率需要放宽至40%～140%。Based on the monitoring data from labs of the country, the quality control of spike recoveries for 51 organic pollutants in surface water was studied systematically and the quality control indexes in two kinds of probability were proposed. The results showed that the quality control ranges for the spike recoveries of the samples of the 51 organic pollutants were wider than that of the blank samples. The spike recoveries for most of the organic pollutants could be controlled in the range of 60% - 120%, while it should be widen to 40% ~ 140% for some individual compounds.
