0555369 MitraThe PI seeks to quantify the flux of particulate phase PAHs from re-suspended sediments as a result of the recent hurricanes in the Gulf of Mexico and compare that flux to PAH flux from the lower Mississippi River and Lake Pontchartrain, also having augmented levels of PAHs from having been a repository of hydrocarbon flux from petroleum contamination in New Orleans. The PI has quantified PAHs in suspended sediments in the Mississippi River, coastal Louisiana, and in the Gulf of Mexico and has pre-hurricane baseline levels of PAHs in these sediments. He will contrast these levels with sedimentary PAHs collected from cores west of the Mississippi River delta (Mississippi River - the realm of influence of Lake Pontchartrain) to that east of the Mississippi River delta (Mississippi River + the realm of influence of Lake Pontchartrain).

0555369 MitraThe PI试图量化由于墨西哥湾最近的飓风而导致的再悬浮沉积物中颗粒相多环芳烃的通量，并将该通量与来自密西西比河下游和庞恰特雷恩湖的多环芳烃通量进行比较，该通量也增加了新奥尔良石油污染引起的碳氢化合物通量的储存库中的多环芳烃水平。PI对密西西比河、路易斯安那州沿海和墨西哥湾的悬浮沉积物中的多环芳烃进行了定量，并在这些沉积物中确定了飓风前多环芳烃的基线水平。他将把这些水平与从密西西比河三角洲以西（密西西比河-庞恰特雷恩湖的影响范围）到密西西比河三角洲以东（密西西比河+庞恰特雷恩湖的影响范围）的岩心收集的沉积多环芳烃进行对比。
