TL;DR: Analyses of two short sediment cores collected from the Pearl River Estuary showed that concentrations of BDE-209 rapidly increased in the upper layers of both cores, coincident with the growth of the electronics manufacturing capacities in the PRD region.

TL;DR: A recent review as mentioned in this paper highlights the major progress over the last decade on characterization of geochemically heterogeneous soil/sediment organic matter (SOM) and the impacts of SOM heterogeneity on sorption and desorption of hydrophobic organic contaminants (HOCs) under equilibrium and rate limiting conditions.

TL;DR: The data preliminarily reveal the state of contamination in this region and give insight into the fate of POPs in this sub-tropical area.

TL;DR: It is shown that residents in Guiyu are at a high risk of exposure to dioxins and the total PCDD/F intake doses far exceed the WHO 1998 tolerable daily intake limit of 1-4 pg of W-TEQ kg(-1) day(-1).

TL;DR: Compared to the soil background contents in Guangdong Province, the mean concentrations of Hg, Cd, Zn, Pb and As in soil of Huizhou are higher, especially Hg andCd, which are 2.82 and 1.79 times the background values, respectively.
