Title: Pyeong-Koo Lee: Innovator in Soil Contamination Analysis

Introduction

Pyeong-Koo Lee is a notable inventor based in Daejeon, South Korea. He has made significant contributions to the field of environmental science, particularly in soil contamination analysis. With a total of five patents to his name, Lee's work focuses on innovative methods for evaluating and resolving soil contamination issues.

Latest Patents

One of Lee's latest patents is a method for resolving the contribution ratio to soil contamination by a plurality of polluters through a sequential extraction scheme and stable isotope analysis scheme. This method involves eluting lead (Pb) stable isotopes at five types of fractions, including cation exchange, carbonate, iron-oxide and manganese hydroxide, organic matters and sulfide, and residual fractions. The Pb stable isotopes obtained in each step are analyzed to determine the contribution ratio to soil contamination using a predetermined resolving equation. Another significant patent is a method for evaluating the final equilibrium pH of contaminated soil on-site by using paste pH. This method includes measuring the paste pH by adding a solution to the contaminated soil and evaluating the final equilibrium pH based on the initial pH.
