摘要
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。
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.
