    • 摘要: Effects of soil particles on the adsorption performance of chloredane,and the subsequent acute toxicity of the contaminated soil on luminescent bacteria,were studied in this paper.The research results indicate that the adsorption capacity of chloredane by soil particles followed the sequence of clay (< 2 μm) ≈ silt (2 ~ 20 μm) >coarse sand (200~2 000 μm) > fine sand (20 ~200 μm).It was most reasonable to describe the adsorption behavior using a Freundlich isotherm model,as its tninimal linear correlation coefficient (R2) value was 0.84.Analysis of the adsorption dynamics indicated that a pseudo-first-order model fits the experimental data very well,as its maximum linear correlation coefficient (R2) value reached 0.999.The inhibitory rate of acute toxicity from contaminated soil particles on luminescent bacteria was as follows:fine sand (-21%) ≈ coarse sand (-21%) > silt (-13%) > clay (-9%),indicating that the acute toxicity to luminescent bacteria was negatively correlated with the adsorption performance of the soil particles.%以典型有机氯农药氯丹为研究对象,重点研究了不同粒径土壤颗粒对氯丹的吸附特性及其对发光菌急性毒性的影响.研究结果表明,不同粒径的土壤颗粒对氯丹的吸附性能依次为:粘粒(<2 μm)≈粉粒(2~ 20 μm)>粗砂(200~2 000 μm)>细砂(20~200 μm).Freundlich等温吸附模型的线性相关系数最小为0.84,对不同粒径土壤吸附数据的拟合均优于Langmuir等温吸附模型.对吸附氯丹的吸附数据更符合准一级吸附动力学,其线性相关系数最高达到0.999.四种土壤颗粒浸出液对发光菌毒性的发光抑制率依次为细砂(-21%)≈粗砂(-21%)>粘粒(-13%)>粉粒(-9%),即发光菌的急性毒性与土壤颗粒的吸附性能负相关.

    • 摘要: 采用微波辐照技术修复氯丹污染土壤,以氯丹的挥发率和分解率为主要评价指标,研究了微波辐照条件对土壤修复效果的影响。实验结果表明:氯丹的挥发率随微波辐照功率的增大而增大,而氯丹的分解率则无明显变化;当活性炭与土壤质量比为9∶120时,氯丹的去除效果最好,去除率达89%;氯丹的挥发性能在前20 min内随微波辐照时间的延长而增强,而氯丹的分解性能则刚好相反;当土壤含水率为15%时,氯丹的挥发率最高,为2.5%,而氯丹分解率最小,为16.8%;在酸性偏中性范围内氯丹的去除效果较差,随土壤pH的不断增大,氯丹的挥发率明显升高,且氯丹的分解率也增大。%The chlordane-contaminated soil was treated by microwave irradiation technology. The effects of microwave irradiation conditions on soil remediation were studied using volatilization rate and decomposition rate of chlordane as the main evaluation index. The experimental results show that:The volatilization rate of chlordane increases with the increase of microwave irradiation power,while the decomposition rate of chlordane does not change obviously;When the mass ratio of activated carbon to soil is 9∶120,The removal effect of chlordane is the best with 89%of removal rate;The volatile performance of chlordane is enhanced with the extending of microwave irradiation time within the first 20 min,while the decomposition performance of it is opposite;When the water content of the soil is 15%,the highest volatilization rate of chlordane is 2.5%and the lowest decomposition rate of chlordane is 16.8%;The removal effect of chlordane is poor in acidic neutral range,while the volatilization rate and decomposition rate of chlordane are increased with the increasing of soil pH.

    • 摘要: 在实验室模拟条件下,研究了白腐真菌Phlebia lindtneri GB1027对有机氯农药氯丹污染土壤的修复作用及影响因素.结果表明,白腐真菌在土壤中较少受到土著微生物的竞争影响,在灭菌和未灭菌土壤中对氯丹的去除率相差不大.木屑、秸秆和马铃薯均可作为营养物和生长载体促进白腐真菌对土壤中氯丹的降解,其中木屑的强化效果最佳,其次为秸秆.本试验条件下,白腐真菌接种量越大,对氯丹的去除效果越好,当接种量为15~20 mL时生物修复效率最高.在氯丹浓度为5~100 mg/kg的污染土壤中,菌株均显示出较好的修复效果,尤其对100 mg/kg的氯丹的30 d平均降解速率达到最高的1.71 mg/(kg·d).菌株对土壤温度和pH具有较宽的适应范围,污染土壤生物修复的最适温度范围是25~35°C,最适pH范围是4.0~6.0.本研究结果表明该白腐菌株具有应用于氯丹污染场地修复的潜力.

    • 摘要: Objective] This study almed to compare the effects of three absorbing medium on microwave degradation of chIordane in contaminated soiI under alkaline condition. [Method] SoiI sampIes were coI ected from the original site of a reIocated pesticide production enterprise as experimental materials, to investigate the effects of Cu2O, MnO2 and activated carbon powder as absorbing medium on soiI warming and removal rate of chIordane under alkaline condition with 20% moisture content. In addition, the effects of activated carbon as the optimal absorbing media on the removal rate of chIordane in contaminated soiI were analyzed, and the effects on the removal rate of chIordane in different weights of soiI sampIes were investigated. [Result] The effects of three different absorbing medium on the removal rates of chIordane demonstrated a descending order of activated carbon > MnO2 > CuO2. Under the same microwave condition, the removal rate of chIordane decreased with the increase of soiI weights, but the utiIization efficiency of microwave was improved continuousIy and tended to be stabiIized with the increase of soiI weights. [Conclu-sion] This study provided a theoretical basis for further Iarge-scale appIication in soiI remediation.%[目的]比较碱性条件下3种吸波介质对微波法降解土壤中氯丹的影响。[方法]以农药生产企业搬迁遗留场地土壤为研究对象,研究了在含水率为20%、碱性条件下 Cu2O、MnO2、粉末活性炭3种吸波介质对土壤升温及氯丹去除率的影响;同时以活性炭为最佳吸波介质,研究了其添加前后对土壤中氯丹去除率的影响,并考察了增大土壤处理量对氯丹去除率的影响。[结果] Cu2O、MnO2、粉末活性炭3种吸波介质对氯丹去除率的影响大小排序为:粉末活性炭>MnO2>Cu2O。相同微波条件下,氯丹去除率随土样质量增加而降低,但微波利用效率随土样质量增加而不断提高并趋于平衡。[结论]为进一步的工程应用提供了理论依据。

    • 摘要: Chlordane, endosulfan and endosulfan sulfate in the surface seawater of Laizhou Bay and its adjacent sea area were analyzed in order to provide a scientific data for the appraisal of ecological risk and the quality of seawater. In August and September of 2012, 51 stations were set up evenly in the study sea area. The surface seawater collected from these stations was analyzed by GC-ECD. Concentrations of chlordane, endosulfan and endosulfan sulfate were N.D. (Not detected)~0.58 ng/L, N.D.~0.85 ng/L, N.D.~2.18 ng/L in August and N.D.~0.84 ng/L, N.D.~2.13 ng/L, N.D.~1.94 ng/L in September respectively. Distribution of two organic chlorinated pesticides was affected by the inputs of terrestrial pollution, and their concentrations showed a decreasing trend from the inshore to offshore waters. Pollution of the two organic chlorinated pesticides was at an acceptable level. But the new inputs and accumulation of endosulfan should be concerned.%对莱州湾及其邻近海域表层海水中氯丹、硫丹及硫丹硫酸盐含量进行调查研究,为该海域海水质量状况及生态风险评价提供科学数据。2012年8月、9月,在调查海域设置51个站位,取其表层海水,用气相色谱法对氯丹、硫丹及硫丹硫酸盐含量进行检测。8月氯丹、硫丹及硫丹硫酸盐浓度范围依次为N.D.(Not detected)~0.58 ng/L、N.D.~0.85 ng/L、N.D.~2.18 ng/L,9月依次为N.D.~0.84 ng/L、N.D.~2.13 ng/L、N.D.~1.94 ng/L。两种有机氯农药受陆源性输入影响,呈现出由近岸向远海递减的趋势;研究海域整体污染程度处于一个可接受的水平,但海域中有新的硫丹污染物输入和积累,需要引起一定重视。
