The par tition behavior of several aromatic pollutants was determined in a variety of Water-hydrophobic cosolvent mixture. It was found that the partition coefficients of solutes in cosolvent-water system are linearly related with the volume concentration of each hydrophobic solvent in organic phare and the partition coefficients of solutes in single solvent-water system. A quantitative relationship was proposed in this paper.

本文测定了几种芳烃污染物在多组份有机相与水相之间的分配系数,发现污染物在这种多组份两相体系的分配系数与组成有机相的各种有机溶剂对污染物的萃取常数及其体积分数有关,并提出了相应的定量关系式。

In this paper, changes of enzymes involved in the degradation of recalcitrant aromatic pollutants from white rot fungus Phlebia radiata I 5 6 and cometabolism of biphenyl and varatryl alcohol by this fungus under nitrogen nutrition rich were studied. Results from the experiment showed that C/N concentration ratio in the culture media played an important role on the activity of LiP. Under the condition of high concentration ratio of C/N or N/C, activity of LiP was higher, but higher activity of...

In this paper, changes of enzymes involved in the degradation of recalcitrant aromatic pollutants from white rot fungus Phlebia radiata I 5 6 and cometabolism of biphenyl and varatryl alcohol by this fungus under nitrogen nutrition rich were studied. Results from the experiment showed that C/N concentration ratio in the culture media played an important role on the activity of LiP. Under the condition of high concentration ratio of C/N or N/C, activity of LiP was higher, but higher activity of MnP only followed the low concentration of glucose or tartrate ammonium concentration in the media, when concentration of glucose or tartrate ammonium was more than 0 01 mol/L, the activity of MnP dropped down quickly. Veratryl alcohol increased the activity of LiP and MnP as well as the amount of ·OH radical free under different concentration of nitrogen or carbon source; ascorbic acid, a scavenger of ·OH radical free, brought the opposite effect to that of the veratryl alcohol on the LiP and MnP activity. Under nitrogen nutrition rich condition removal percentage of biphenyl was lower, however, under cometabolic condition of veratryl alcohol and biphenyl, the degradation was enhanced obviously, moreover, intermediate products accumulated in the media during the cometabolic degradation process of biphenyl and veratryl alcohol was different from these which was found in the process of separate degradation of biphenyl or veratryl alcohol.

In order to study pollution situation in coking areas, ambient air quality of rural settlements and aromatic pollutants in cultivated soils, several samples were collected in situ and analyzed. Aromatic pollutants, such as benzene and naphthalene, in the cultivated soils surrounding a coal gasification plant were analyzed and determined by Gas Chromatography (GC). The results showed that (1): the highest averaged values of TSP, SO2 and BaP daily were more than the Second-Level of the Ambient Air...

In order to study pollution situation in coking areas, ambient air quality of rural settlements and aromatic pollutants in cultivated soils, several samples were collected in situ and analyzed. Aromatic pollutants, such as benzene and naphthalene, in the cultivated soils surrounding a coal gasification plant were analyzed and determined by Gas Chromatography (GC). The results showed that (1): the highest averaged values of TSP, SO2 and BaP daily were more than the Second-Level of the Ambient Air Quality Standard (GB3095-1996) by 10.76, 3.53and 12.1 times, respectively. (2): Gaseous pollutant discharges in coking production had a significant effect on cultivated soils and plants. It was discovered that benzene content in soils rangedfrom 6.148 to 11.96 mg/kg, toluene 1.56 to 5.238 mg/kg, xylene 7.118 to 9.688 mg/kg. Benzene-like compounds in leaf coats were in the highest amount, with an order: benzene 36.8 mg/kg, toluene 10.22 mg/kg, and xylene 41.43 mg/kg.

通过实地采样 ,分析了炼焦地区的环境空气质量,同时用气相色谱法分析了焦化厂周围农业土壤中的多环芳烃类污染物的含量。结果表明:①焦炭生产地区TSP、SO2 和BaP日均最大值超过GB3095 -1996二级标准值的10、2.5和11.1倍。②焦化厂周围农业土壤受焦化厂气质污染物排放的影响 ,土壤中苯系物含量较高 ,其中苯的含量为6.148~11.96mg/kg,甲苯含量为1.56~5.238mg/kg,二甲苯含量为7.118~9.688mg/kg。焦化厂厂区植物叶片覆盖物中苯系物含量最高 ,含苯36.8mg/kg,甲苯10.22mg/kg ,二甲苯41.43mg/kg。
