MEASUREMENT METHOD FOR POLLUTION INDEX USING ANALYSIS OF ELEMENT REDUCING A TOXICITY

摘要

PURPOSE: A method for measuring soil contamination by environmental factor is provided to predict toxicity of soil based on the concentration of heavy metal. CONSTITUTION: A method for measuring soil contamination comprises: a step of collecting and drying sample from soil; a step of mixing the dried sample with metal salt compound solution to prepare mixture solution; a step of filtering the mixture solution to separate particle and solution; a step of measuring ion concentration; a step of collecting toxicity by heavy metal; and a step of calculating CEC50 value of the heavy metal atoms.
