The present paper describes a method known as the solid phase micro-extraction(SPME)to determine the organic compounds in monitoring the environment.In comparison with the existing technologies,SPME offers more advantages,such as simplicity,speed and greater sensitivity.It has been widely used for monitoring different phases,e.g.air,water,soil and sediment,as well as biological purposes.In air monitoring,the combination of SPME with GC/MS can be used to identify 75 contaminants,including 40 alkanes,1 alkene...
