In our analytical investigation, N-butylbenzene has never been detected in all samples, but DBCP has been detected in four soil samples. We present not only analytical results but also analytical methods and analytical conditions as a function of analytes and matrices. 1. ¼­ ·Ð ³»ºÐºñ°è Àå¾Ö¹°ÁúÀº ³»ºÐºñ°èÀÇ Á¤»óÀûÀÎ ±â´ÉÀ» ¹æÇØÇÏ´Â ¹°Áú·Î¼­ ȯ°æ Áß ¹èÃâµÈ ¹°ÁúÀÌ Ã¼³»¿¡ Èí¼öµÇ¾î ¸¶Ä¡ È£¸£¸óó·³ ÀÛ¿ëÇÑ´Ù°í ÇÏ¿© ȯ°æÈ£¸£¸ó1,2,3)À̶ó°íµµ ºÒ¸® ¿ö Áø´Ù.
