TLDR
The physico-chemical changes such as reduction in pH and salinity in water environment induced by land reclamation appear to be responsible for metal mobility in the sediment-groundwater system.About:

Journal ArticleDOI
Heavy metal fractions and ecological risk assessment in sediments from urban, rural and reclamation-affected rivers of the Pearl River Estuary, China
TL;DR: The redundancy analysis (RDA) revealed that both urbanization and reclamation processes would cause similar metallic characteristics, and sediment organic matter (SOC) might be the prominent influencing factor.
Journal ArticleDOI
Characterization and environmental impact analysis of sea land reclamation activities in China
TL;DR: Li et al. as mentioned in this paper combined qualitative and quantitative information to focus on reclamation activities in China and highlight the major impacts: eco-system damage and geological disasters, and the deterioration of marine environmental quality resulting from polluted air, water, soil, and sediment.
Journal ArticleDOI
Speciation and mobility of heavy metals in mud in coastal reclamation areas in Shenzhen, China
TL;DR: In this article, a sequential extraction method was used to study the operationally determined chemical forms of five heavy metals (Cu, Ni, Pb, Zn, and Cd) in the mud samples.
Journal ArticleDOI
The role of radial oxygen loss and root anatomy on zinc uptake and tolerance in mangrove seedlings
TL;DR: Investigation of root anatomy, radial oxygen loss (ROL) and zinc uptake and tolerance in mangrove plants revealed that B. gymnorrhiza, which possessed the 'tightest barrier' in ROL spatial patterns among the three species studied, took up the least Zn and showed the highest Zn tolerance.
Journal ArticleDOI
Metal (Pb, Zn and Cu) uptake and tolerance by mangroves in relation to root anatomy and lignification/suberization.
Hao Cheng,Zhao-Yu Jiang,Yong Liu,Zhihong Ye,Mei-Lin Wu,Cui-Ci Sun,Fu-Lin Sun,Jiao Fei,You-Shao Wang +8 more
TL;DR: A barrier property of the lignified/suberized exodermis is proposed in dealing with the stresses of heavy metals, such that the mangroves which possessed more extensive lignification/Suberization within the exodermal cell walls appeared to exhibit higher metal tolerance.

Spatial variation of heavy metals in surface sediments of Hong Kong mangrove swamps
Nora F.Y. Tam,Yuk Shan Wong +1 more
TL;DR: Field observation reveals that seven mangrove stands received industrial, livestock and domestic sewage as well as pollution from mariculture activities, suggesting that anthropogenic input is the main source of heavy metal contamination in Hong Kong mangroves.
Journal ArticleDOI
Heavy metal distribution in marine sediments from the southwest coast of Spain
TL;DR: It is found that Zn is the most mobile metal and showed the highest percentages in the acid-soluble fraction (the most labile), especially in the central coastal area, where the samples contained over 50% of this element associated with this fraction.
Journal ArticleDOI
The study of metal contamination in urban soils of Hong Kong using a GIS-based approach.
TL;DR: Several hot-spot areas of metal contamination were identified from the composite metal geochemical map, mainly in the old industrial and residential areas, and the Pb isotope composition of the contaminated soils showed clear anthropogenic origins.
Journal ArticleDOI
Trace and Toxic Metals in Wetlands—A Review
TL;DR: The mobility and plant availability of many trace and toxic metals in wetland soils is often substantially different from upland soils as discussed by the authors, and metals tend to be retained more strongly in the wetland soil compared with the upland soil.
Journal ArticleDOI
Normalization and elemental sediment contamination in the coastal United States.
TL;DR: The spatial extent of contamination has been examined, and it was found that severe contamination is mostly limited to small areas near large population centers.
