Abstract: Organic dyes have become an important type of organic pollutants occurred in environment of China.Bio-concentration factors(BCF)of reactive X-3B red dye and its distribution in corp tissues were studied using the ecologically microcosmic method of water culture and soil culture.The results indicated that BCF was 252.1~409.4 under the experimental conditions.According to the tested BCF values and relevant judging standards,the ability of living organisms concentrating the dye was at middle levels.The concentration of the dye accumulated in roots of the tested crops was higher than 10 times of that in their overground parts,in particular,the trend in radish whose roots are used as human food was very obvious.As for the crops whose overground seeds are used as human food and due to the integrality of soil-crop systems,the concentration of the dye accumulated in these crops and their tissues was in order of soybean>wheat>rice,and rootstem>leaf>seed without hulls.The maximum concentration of the dye accumulated in rice seed without hulls could be even up to 23.33μg·kg-1,although the accumulation was lowest among the three crops.Therefore,ecological risk from pollution of the dye cannot be neglected.
