Bioconcentration and Elimination of Nitrobenzenes by the Alga

In the paper,the law of bioconcentration and elimination of nitrobenzene by aquatic organisms(algaes) are studied which offered scientific basis for effects of ecology and environment and ecological risk assessment.The results are as follows:Through enriched culture in the culture condition in organic salt,the natural algaes in the Songhua River are done in the test.The concentration of NB added to the medium is 8.3±1.0mg/L.The results are as follows:both the rate of enrichment and release by algaes are rapid.
