以直链烷基苯(linear alkyl benzenes,LABs)为人文活动示踪物,研究其在黄河三角洲潮间带环境中的分布和降解特征。沉积物样品采集于2007年9月、2008年4月和7月,结果表明,调查区域表层沉积物中LABs(C10～C14)含量为(0.33～37.33)×10-6(干重),呈现由近岸向离岸,由接近河口区向远离河口区逐渐降低的趋势,反映出人文活动对潮间带的水平影响过程。沉积物柱状样中LABs(C10～C14)的含量为(5.67～79.67)×10-6,其随深度的波动变化,表征出该区域中心城市洗涤剂用量的季节特点和年度变化。
Linear alkyl benzenes (LABs) were used as tracers for human activities to study their distribution and degradation characteristics in the intertidal zone of the Yellow River Delta. Sediment samples were collected in September 2007, April and July 2008, and the results showed that the content of LABs (C10 ~ C14) in the surface sediment of the survey area was (0.33 ~ 37.33) × 10-6 (dry weight) From near shore to offshore, from the estuary area gradually away from the estuary trend, reflecting the level of human activities on the impact of the intertidal process. The content of LABs (C10 ~ C14) in column sediment samples was (5.67 ~ 79.67) × 10-6, which showed the seasonal characteristics and annual changes of detergent dosage in the central city in the region with the variation of depth.
