The relationship between polycyclic aromatic hydrocarbons (PAHs) in wetland surface sediments and adjacent land use was assessed in the Elizabeth River, VA, an urbanized sub-estuary of the Chesapeake Bay. Significant differences (p<0.05) in surface sediment PAH concentration between sites indicated adjacent land use had a substantial influence on PAH concentration in wetland sediments. Wetlands adjacent to parking lots and petroleum industrial sites exhibited the highest PAH concentrations of all wetlands examined. Overall, commercial land uses had the highest PAH concentrations and automotive sources dominated (52-69%) PAH input to wetland surface sediments irrespective of adjacent land use.
在切萨皮克湾一个城市化的河口——弗吉尼亚州伊丽莎白河中，评估了湿地表层沉积物中多环芳烃（PAHs）与相邻土地利用之间的关系。各采样点表层沉积物中PAH浓度存在显著差异（p<0.05），表明相邻土地利用对湿地沉积物中PAH浓度有重大影响。在所有被检测的湿地中，毗邻停车场和石油工业场地的湿地PAH浓度最高。总体而言，商业用地的PAH浓度最高，无论相邻土地利用情况如何，汽车源在湿地表层沉积物PAH输入中占主导地位（52-69%）。
