HRGC/HRMS ANALYSIS OF MIREX IN SOIL IN LIYANG, CHINA
China is a country with the greatest diversity of termites and the most severe termite damage in the world. Mirex has been widely used in China for termite control. Liyang city, located in the south of Jiangsu Province, China, is an important production base of mirex. Soil samples were collected from 23 sites in Liyang city in February, 2009. HRGC/HRMS (high-resolution gas chromatography /high-resolution mass spectrometry) was employed for mirex analysis. It was found that the detected levels of mirex in soil in Liyang were 2.9 ～ 4300 pg/g dw (dry weight), with the geometric mean 26.83 pg/g dw and the geometric standard deviation 5.02. The highest level occurred at the site near the Guanghua Chemical Company, which has produced mirex for more than 10 years. It implied the contribution of industrial activities to the mirex levels in the environment in Liyang city. However, the emission from the factory only influenced a rather limited adjacent area. The distribution and fate of mirex in Jiangsu Province were also discussed using fugacity model. It is estimated that the total amount of mirex in the environment in Jiangsu province is about 460 kg. Most of the mirex existed in soil, accounting for more than 95％ of the total amount of mirex.
