Claim Text:
1. A method for verifying representativeness of samples collected in a contaminated soil, the method comprising: horizontally and vertically collecting the samples from the contaminated soil on a basis of a stratum of the contaminated soil at a predetermined sampling interval; measuring a total concentration of trace elements by using a chemical analysis instrument to analyze the collected samples according to the sampling interval, wherein the total concentration of the trace elements is measured through a pretreatment by using aqua regia and a chemical analysis by using an inductively coupled plasma-atomic emission spectroscopy (ICP-AES) instrument as the chemical analysis instrument; and determining horizontal and vertical sampling intervals and a sample number based on a statistical analysis result for the total concentration of the trace elements, wherein the horizontal collecting of the samples comprises regularly setting the sampling intervals and gradually widening the sampling intervals in a horizontal direction by a predetermined distance; wherein the vertical collecting of the samples comprises regularly setting the sampling intervals and gradually widening the sampling intervals in a vertical direction by a predetermined distance, and wherein the horizontal sampling interval is regularly set within 30 m, the vertical sampling interval is set to at least 2 m, the sample number of vertically collected samples is at least 4, and an area for vertically collecting the samples is at least 500 m
