| Abstract: | Some problems of quality control in detection of organic pollutants with gas chromatography are stated. The detecting precision and recovery of standard should be based on the property of samples and detected species. It is suggested that detecting methods of organic pollutants,quality control method and index for the reality in China should be established as soon as possible. |
