小东江底泥中挥发酚的垂向分布研究

The Study of Vertical Allocation of Volatile Phenol in Xiaodong River's Sediments

将沿小东江流域布点采集到的底泥样 ,根据其理化性质 ,从上到下分为A( 0～ 10cm)、B( 10～ 2 0cm)、C( 2 0～ 35cm)、D( 35～ 65cm)层 ,分析发现 :挥发酚含量B >A >C >D层 ;A～D层挥发酚含量最高点分别对应的是细砂土、面砂土、砂粘土和面砂土。

According to their physical and chemical properties,the sediment samples from the Xiaodong River were divided into four layers from up to down:A (0～10 cm),B(10～20 cm),C(20～35 cm),D(35～65 cm).It was found that the content of volatile phenol in B-layer is the highest,that on D-layer is the lowest,and that the vertical distribution is generally B>A>C>D.The highest points of volatile phenol content in A,B,C and D layers are respectively correspondent with fine sand soil,grain sand soil,sandy clay and grain sand soil.
