TLDR
The degree of metal bio-accumulation in leaves and pneumatophores suggest contrasting hydrological behaviors and near-surface geochemical conditions favoring differential metal uptake by mangrove plants in the two sites.About:

Trace metal geochemistry in mangrove sediments and their transfer to mangrove plants (New Caledonia)
TL;DR: Assessment of the distribution of some trace metals in the tissues of various mangrove plants developing downstream highly weathered ferralsols in New Caledonia found Cu and Zn metals had a greater mobility in the plant, and were characterized by high bioconcentration and translocation factors compared to the other metals.

Accumulation of trace metals in grey mangrove Avicennia marina fine nutritive roots: The role of rhizosphere processes
TL;DR: Investigation of mangrove sediments and associated fine nutritive roots collected from five major embayments of Sydney estuary (Australia) for geochemical studies finds a strong linear correlation between metal concentrations in fine nutritives roots vs. total and bio-available contents in sediments.

Ecological risk and pollution history of heavy metals in Nansha mangrove, South China
Qihang Wu,Qihang Wu,Nora F.Y. Tam,Jonathan Y.S. Leung,Xizhen Zhou,Jie Fu,Bo Yao,Xuexia Huang,Lihua Xia +8 more
TL;DR: Results found that the surface sediment in Nansha mangrove was severely contaminated with heavy metals, probably due to the discharge of industrial sewage into the Pearl River Estuary, indicating that heavy metal pollution has been deteriorating since 1979.

Changes in acidity and metal geochemistry in soils, groundwater, drain and river water in the Lower Murray River after a severe drought.
Luke M. Mosley,Luke M. Mosley,Luke M. Mosley,Rob Fitzpatrick,Rob Fitzpatrick,David J. Palmer,Emily Leyden,Paul Shand,Paul Shand,Paul Shand +9 more
TL;DR: P pH neutralisation and rapid oxidation, hydrolysis, and precipitation of solid Al and Fe phases occurred in a localised area and Acidity is persisting (>3 years) following a return to pre-drought water levels.
Journal ArticleDOI
Assessment of biotic response to heavy metal contamination in Avicennia marina mangrove ecosystems in Sydney Estuary, Australia.
TL;DR: This study supports the notion that A. marina mangroves act as a phytostabilizer in this highly modified estuary thereby protecting the aquatic ecosystem from point or non-point sources of heavy metal contamination.

Determination of carbonate and organic matter in calcareous sediments and sedimentary rocks by loss on ignition; comparison with other methods
TL;DR: In this article, a modified ignition loss method is described for determining organic and carbonate carbon in calcareous sedimentary materials using equipment found in most laboratories and has been found to equal or excel the accuracy and precision of other methods tested and has the advantage of being considerably faster if large numbers of samples are to be analyzed.

Abstract: This handbook of chemical tests for diagnostic, agricultural, and environmental purposes promotes the use of consistent methods, procedures and terminologies in soil and land surveys undertaken throughout Australia. Soil and water chemical methods include sampling and sample preparation, and measuring electrical conductivity and pH. Soil analysis includes: chloride, carbon, nitrogen, phosphorus, sulfur, gypsum, Other CABI sites

Trace metal behaviour in estuarine and riverine floodplain soils and sediments: A review
TL;DR: Iron and manganese (hydr)oxides were found to be the main carriers for Cd, Zn and Ni under oxic conditions, whereas the organic fraction was most important for Cu.

Pyritization of trace metals in anoxic marine sediments
TL;DR: In this paper, the pyritization of reactive trace elements in different anoxic marine sediments was investigated to determine the importance of factors such as reactive-Fe, pyrite content and salinity in controlling this process.
