The analysis of 4 borehole cores shows that the paleo-valley of the Yangtze River in Nanjing reach has several imbedded terraces, with deep paleo-channel below –60 m. The 14C ages confirm that the deep incised-valley below -60 m at Nanjing reach
is Yangtze River paleo-valley during the LGM. Appropriate formula was selected to calculate the velocity of flow, discharge, etc. according to the paleo-valley configuration and the particles size grading of sediments on the bottom of the valley.
Identification of the sources of polycyclic aromatic hydrocarbons on molecular and isotopic characterization from the Yangtze estuarine and nearby coastal areas

Samples of suspended particulate matters (SPMs), surface sediment and road dust were collected from the Yangtze estuarine and nearby coastal areas, coastal rivers, and central Shanghai. The samples were analyzed for the presence of 16 polycyclic
. Principal component analysis (PCA) integrated with molecular mass indices indicated that gasoline, diesel, coal and wood combustion and petroleum-derived residues were the main sources of PAHs in the Yangtze Estuary.
