Abstract: PURPOSE: A method for evaluating toxicity in a plant is provided to estimate the concentration of heavy metals in soil by a plant germination test in a heavy metal solution, and to evaluate toxicity. CONSTITUTION: A method for evaluating toxicity in a plant due to heavy metals in soil comprises: a step of performing a first germination test in a heavy metal solution and preparing regression analysis equation 1(y=97.96_e^-0.008x1) of plant toxicity index(y) with respect to the concentration(x1) of the heavy metals; a step of performing a second germination test and preparing regression analysis equation 2(y=84.146_e^-0.001x2) of plant toxicity index(y) with respect to the concentration of the heavy metal(x2); a step of preparing equation 3(x_2=8x1-151.904) when the plant toxicity index(y) in equations 1 and 2 is identical; and a step of estimating the concentration of the heavy metals in the soil through the equation 3. The heavy metals are cadmium(Cd) or lead(Pd). The plant toxicity index includes germination rate and the length of a germinated root. [Reference numerals] (AA) Cd concentration in solution(mg/L); (BB) Aqueous solution; (CC) Soil; (DD,GG) Germination percent(%); (EE) Cd concentration in soil(mg/kg); (FF) Pb concentration in solution(mg/L); (HH) Pb concentration in soil(mg/kg)
