不同处理方法去除有机质对沉积物吸附有机农药和非离子表面活性剂的影响

Effect of different sediment treatments on the adsorption behaviors of organic pesticides and nonionic surfactant on sediment

沉积盆地内能够形成天然气水合物的先决条件包括：富含分散有机质的沉积物中充有地下水、深水区的水动力处于滞流状态、存在生物成因的气体、压力与温度具有特定的相关关系等。

Formation of natural gas hydrate in a sedimentary basin depends upon sediments rich in organic matter that are hydrated , static hydrodynamic conditions in deep water areas , existence of biogenic gas , and pressure specifically related to temperature .

水系中泥炭沉积物可吸附活动态金属元素，在背景地段可形成次生富集和假异常。有机质影响水系沉积物异常，为干扰因素，应消除有机质影响。

沉积物总汞与有机质显著相关，沉积物中高汞含量的地点都在高水汞点的下游，与河流的动力沉积特点一致。

Locations with high mercury content in sediment are in the downstream of locations with high mercury content in water .

这表明δ13Corg与C/N在重塑柱状样中各端元有机质的贡献量时依然具有重要指示意义，尽管有机质不可避免的受到沉积物早期成岩和降解作用的影响。

It indicates that δ 13Corg and C / N still have an important role in reconstructing the contribution of end-member organic matter , despite of the inevitable early diagenesis and degradation .
