| ABSTRACT |
| The pot-culture method combined with chemical and statistical analyses was used to get basic data for determination of the food-security indexes related to combined pollution of Cr and phenol in soil-rice systems. Regression analyses according to the experimental result indicated that the critical concentrations of Cr and phenol in brown rice were 0.37 and 0.33 mg kg-1, respectively, under the condition of Cr-phenol combined pollution. |
| Key Words: chromium, combined pollution, food-security index, phenol, soil-rice system |
