The Pearl River Estuary Pollution Project (PREPP)

Continental Shelf Research, 2004
The Pearl River Estuary pollution project (PREPP) was conceived at the Hong Kong University of Science and Technology (HKUST) during the 1996 to 1998 period to complement some ongoing work by the Government of the Hong Kong SAR on water quality issues in Hong Kong waters.

3D Numerical Model for Pearl River Estuary

Journal of Hydraulic Engineering, 2001
A 3D numerical model with an orthogonal curvilinear coordinate in the horizontal direction and sigma coordinate in the vertical direction has been developed. This model is based on POM (Princeton Ocean Model). In this model a second moment turbulence closure submodel is embedded and the stratification caused by salinity and temperature is considered ...

Persistent organic pollution characterization of sediments in Pearl River estuary

Chemosphere, 2006
As a byproduct of rapid urbanization and industrial development in the Pearl River estuary of South China, excessive release of various types of persistent toxic substances were conveyed from agricultural, industrial and municipal discharges at upstream section down into the estuary largely via various river outlets. In this paper, a persistent organic

Trace Metals in Pearl River Estuary Organisms

2020
Important concepts when considering the biology of trace metals in aquatic organisms are uptake processes, bioavailability, bioaccumulation and toxicity. Recent decades have testified the dramatic progress in our understanding of these fundamental ecotoxicological aspects of trace metal biology.

Three-dimensional pollutant transport model for the Pearl River Estuary

Water Research, 2002
In this paper, the development and implementation of a three-dimensional, numerical pollutant transport model, which is based on an orthogonal curvilinear coordinate system in the horizontal direction and a sigma coordinate system in the vertical direction, is delineated.

Responses of the river plume to the external forcing in Pearl River Estuary

Aquatic Ecosystem Health & Management, 2012
The interaction of river flow, tidal mixing, basin morphology and wind produces a different type of river plume in the Pearl River Estuary. In this paper, a three-dimensional numerical model has been used to study the response of the river plume to different forcings in the Pearl River Estuary.

Sediment trapping by haloclines of a river plume in the Pearl River Estuary

Continental Shelf Research, 2014
Abstract Sediment trapping by the halocline of a river plume was investigated over a spring-neap tidal cycle in the 2010 dry season in the Pearl River Estuary. Benthic tripod observations and concurrent shipboard measurements were conducted to examine mean and turbulent flows, and sediment distributions.

Hong Kong at the Pearl River Estuary: A hotspot of microplastic pollution

Marine Pollution Bulletin, 2015
Large plastic (>5mm) and microplastic (0.315-5mm) debris were collected from 25 beaches along the Hong Kong coastline. More than 90% consisted of microplastics. Among the three groups of microplastic debris, expanded polystyrene (EPS) represented 92%, fragments represented 5%, and pellets represented 3%.

Distribution and Fate of Organochlorine Pollutants in the Pearl River Estuary

Marine Pollution Bulletin, 1999
Samples of surface sediment and suspended particulate matter (SPM) were collected from the Pearl River estuary, China, and the distribution and concentration of hexachlorocyclohexanes (HCHs), DDTs and polychlorinated biphenyls (PCBs) were extensively studied. The concentration ranges of HCHs, DDTs and PCBs in the sediments were 0.28–1.23 ng g−1, 1.36–8.
