The sedimentary fluxes of polycyclic aromatic hydrocarbons in the Yangtze River Estuary coastal sea for the past century

How polluted is the Yangtze river? Water quality downstream from the Three Gorges Dam

“…), and polycyclic aromatic hydrocarbons were analyzed in the sediments of the Yangtze estuary (Liu et al, 2001(Liu et al, , 2003aChen et al, 2002a;Guo et al, 2007). Wu et al (1999) found relatively small sediment concentrations of persistent organochlorines in spite of the high production and usage in China.…”

Contamination status of dioxins in sediment cores from the Three Gorges Dam area, China

“…POPs such as halogenated compounds (HCH, DDT, PCB, OCP, etc.) and polycyclic aromatic hydrocarbons (PAHs) were analyzed in the sediments of the Yangtze estuary (Chen et al 2002;Guo et al 2007). Recent study investigated dissolved and particle-associated organic pollutants in the river downstream of the TGD (Müller et al 2008); some articles related to PCDD/Fs, PCBs, PAHs, and OCPs in water of Three Gorges Reservoir (TGR) were published (Chen et al 2008;Wang et al 2009).…”

Variability and Significance of Labile Metals in the Offshore Mud Area of the East China Sea

“…Generally, the sediment cores reveal lower concentrations of metals in deep depth, while increasing concentrations in upper sediments for much more serious worldwide human pollution recently [20][21][22][23] . Therefore, trace metals are important indexes to researches concerning sediment sources, geochemical processes and human influences.…”
