STREAM-SUBSURFACE EXCHANGE, SUSPENDED SEDIMENT TRANSPORT, AND THE COUPLED TRANSPORT OF COLLOIDS AND CONTAMINANTS IN SEDIMENT BEDS

引用

International Journal of Sediment Research 2003年第2期 199-207页

作者： jianhong ren ,Aaron I. PACKMAN Department of Civil and Environmental Engineering Northwestern University Evanston IL USA

Recent interest in the role of sediments in contaminant transport and stream ecology has motivated additional study of both stream-subsurface exchange flows and suspended sediment transport, deposition, and resuspension. Detailed consideration of the hydrodynamic coupling of stream and pore water flows indicates that there will often be a considerable exchange flux between streams and porous stream beds. As a result, suspended sediments are readily carried from the stream into the subsurface where they can deposit due to physico-chemical interactions with the bed sediments. These processes can greatly influence the transport of fine sediments in streams, and also have important implications for the transport and fate of contaminants. Stream-subsurface exchange allows contaminants to interact with streambed sediments, and contaminants such as metals can sorb to colloidal phases, so that contaminant fate also depends to a large extent on the fate of the suspended sediments. Various degrees of interaction between colloids, contaminants, and stream bed sediments can result in a wide range of transport behavior. In addition, contaminant-particle and particle-particle interactions both depend on the background water chemistry (e.g., pH and ionic strength). Fundamental understanding of the underlying processes allows prediction of the coupled transport of suspended sediments and contaminants. These problems have been analyzed by combining fundamental fluid mechanics with appropriate chemical or physico-chemical interactions between contaminants, colloids, and bed sediments. Long-term modeling of fine sediment and contaminant transport in streams will require consideration of dynamic interactions between stream-subsurface exchange hydrodynamics and fine particle transport.

为了探索实际传输过程中H2S在非金属管材中的渗透规律,以不同温度条件下H2S在多层聚合物复合管道中的渗透系数实测值为基准,建立了H2S在多层聚合物复合管道中的渗透模型,并利用渗透理论和渗透公式获得了不同温度、压力条件下H2S在非金属管道增强层中产生的气压和渗透量随时间变化的规律。结果发现:①H2S在聚偏氟乙烯(PVDF)和高密度聚乙烯(HDPE)薄膜中的渗透规律符合Arrhenius关系;②H2S在管道中的渗透气压随温度和管内压力升高而急剧升高,且很快达到平衡,而其渗透量呈一次函数持续增加;③H2S通过内衬层管材的渗透量随温度和管内压力的增大而线性增大,但前者对H2S渗透行为的影响大于后者引起的影响。

Nicosulfuron is the leading acetolactate synthase inhibitor herbicide product, and widely used to control gramineous weeds. Here, we investigated the metabolic process of nicosulfuron into foxtail millet and maize, in order to clarify the mechanism of the difference in sensitivity of foxtail millet and maize to nicosulfuron from the perspective of physiological metabolism and provide a theoretical basis for the breeding of nicosulfuron-resistant foxtail millet varieties. We treated foxtail millet(Zhangzagu 10, Jingu 21) and maize(Nongda 108, Ditian 8) with various doses of nicosulfuron in both pot and field experiments. The malonaldehyde(MDA) content, target enzymes, detoxification enzymes, and antioxidant enzymes, as well as related gene expression levels in the leaf tissues of foxtail millet and maize were measured, and the yield was determined after maturity. The results showed that the recommended dose of nicosulfuron caused Zhangzagu 10 and Jingu 21 to fail to harvest;the yield of the sensitive maize variety(Ditian 8) decreased by 37.09%, whereas that of the resistant maize variety(Nongda 108) did not decrease. Nicosulfuron stress increased the CYP450 enzyme activity, MDA content, and antioxidant enzyme activity of foxtail millet and maize, reduced the acetolactate synthase(ALS) activity and ALS gene expression of foxtail millet and Ditian 8, and reduced the glutathione S-transferase(GST) activity and GST gene expression of foxtail millet. In conclusion, target enzymes, detoxification enzymes, and antioxidant enzymes were involved in the detoxification metabolism of nicosulfuron in plants. ALS and GST are the main factors responsible for the metabolic differences among foxtail millet, sensitive maize varieties, and resistant maize varieties.
