The Polluted Characters of Cr, Toluene and Dimethylbenzene in Contaminated Soil of Dongsheng Chemical Plant in Suzhou

Abstract:

We sampled total of 74 polluted soil samples in the polluted field, and set up 5 surface water inspect spots by means of setting plane sample points and deep well sampling according to the original produce layout and pollution situation of Dongsheng chemical plant. At the same time, we set 4 soil sampling points outside the polluted field, 6 inspect positions of surface water, and 4 atmospheres inspect stations. The total quantity and the concentration of active form of heavy metals elements in the soil samples were analyzed by atomic absorption spectra; and the volatility organic matters in the soil are measured using gas chromatography-mass spectrograph jointed measurement. The results show that the polluted concentration of Cr in sub-surface layer of the field is highest, and the largest concentrations of the total quantity of Cr, Cr6+, toluene and dimethylbenzene are 13900, 4840, 258 and 33.6 mg•kg-1, respectively. The datum show that the soil in the field is heavily polluted by toluene, dimethylbenzene, total Cr, and Cr6+, and some soil is characteristic of strong acid or strong alkali, and surface water inner the field exists heavy Cr6+ pollution.
