Abstract The extraction of solid samples was performed to establish the analytical method of PAHs in environmental samples. The recovery efficiency of the soxhlet, accelerated solvent and microwave extraction were surveyed 64¡­120%, 68¡­100% and 22¡­81%, but the highest recoveries were obtained the dichloromethane(89, 90, 75%) and dichloromethane:methanol(10:1)(96, 94, 81%) in these three methods. The extraction recoveries of soxhlet and accelerated solvent extraction methods were surveyed high recovery efficiency compared to the microwave extraction method but the microwave extraction method can be used very easily. To establish the analytical method of the PAHs in the solid samples, the samples were extracted with the dichloromethane and dichloromethane:methanol(10:1) in the soxhlet, and eluted with 100§¢ of the 10% dichloromethane:n-hexane. Two(A and B) different kinds of the methods were applied to the soil and waste samples. As the result, the internal standards recoveries were obtained 93¡­94%, therefore the established methods can be used to analyzed the PAHs in the environmental samples. 1. ¼­ ·Ð ´ÙÀÌ¿Á½Å·ù(PCDDs/PCDFs), ´Ùȯ¹æÇâÁ·ÅºÈ­¼ö¼Ò·ù(PAHs), Æú¸®Å¬·Î¸®³×ÀÌƼµåºñÆä´Ò·ù(PCBs) µî ȯ°æ ÁßÀ¸·Î ¹èÃâµÇ´Â ¸¹Àº Á¾·ùÀÇ À¯±â¿À¿°¹°ÁúµéÀÌ ±×µéÀÇ µ¶¼ºÀ¸·Î ÀÎÇØ È¯°æÀÜ·ù¼º À¯±â¿À¿°¹°Áú(persistant organic pollutants)·Î ¾Ë·ÁÁ® ÀÖ´Ù1). ´Ùȯ¹æÇâÁ·ÅºÈ­¼ö¼Ò·ù(Polycyclic Aromatic Hydrocarbons, PAHs)´Â µÎ °³ ÀÌ»óÀÇ ¹æÇâÁ·°í¸®¸¦ Æ÷ÇÔÇÏ°í ÀÖ´Â À¯±âÈ­ÇÕ¹°·Î 100Á¾·ùÀÌ»óÀÇ PAHs°¡ ´ë±â ÀÔÀÚ»ó ¹°Áú ¹× ¼®Åº¿¬¼Ò ºÎ»ê¹°¿¡¼­ È®ÀεǾúÀ¸¸ç, ¼ö ¹é ¿©Á¾ÀÇ °³º°¹°ÁúÀÌ ºÒ¿ÏÀü¿¬¼Ò ȤÀº À¯±â¹°ÀÇ ¿­ºÐÇØ·Î ¹ß»ýµÇ¾î ÀÎü¿¡ ¿µÇâÀ» ¹ÌÄ¡´Â ȯ°æ¿À¿° ¹°Áú·Î ¾Ë·ÁÁ® ÀÖ´Ù. ¶ÇÇÑ, ÀÌµé ¹°ÁúÀº ¼®Åº¿¬¼Ò ¹èÃâ¹°, ÀÚµ¿Â÷ ¹èÃâ°¡½º, ÀÚµ¿Â÷ Æó¿ÀÀÏ, ´ã¹è¿¬±â¿Í °°Àº ¿©·¯ ȯ°æ¸Åü¿¡ ÇÔÀ¯µÈ PAHs°¡ ¹ß¾ÏÀáÀ缺ÀÌ ÀÖÀ½ÀÌ ¹àÇôÁ® À̵é PAHs Áß ¸î¸î ¹°ÁúÀ» ¿ì¼±´ë»ó¹°Áú·Î ÇÏ¿© ¹Ì±¹ EPA(16Á¾) ¹× WHO(33Á¾)µî¿¡¼­ °ü¸®ÇÏ°í ÀÖ´Ù2,3,4). º» ¿¬±¸¿¡¼­´Â PAHsÀÇ ºÐ¼®¹ýÀ» È®¸³Çϱâ À§ÇØ Àüó¸® ¹æ¹ý¿¡ ´ëÇÑ ½ÇÇèÀ» ¼öÇàÇÏ¿´À¸¸ç, È®¸³µÈ ºÐ¼®¹ýÀ» ÀÌ¿ëÇÏ¿© ½ÇÁ¦ ȯ°æ½Ã·áÀÎ Åä¾ç ¹× Æó±â¹° ½Ã·á¸¦ ºÐ¼®ÇÏ¿´´Ù.
