Heavy metal distribution in some French forest soils: evidence for atmospheric contamination [PDF]
, 2003 This study is one of very few dealing with the distribution and the origin of heavy metals in French soils from a priori non-polluted forest areas. The abundance of heavy metals measured in these soils decreases as follows: Cr) Zn)Pb)Ni)Cu)Co4Cd. Total

Interactions between metals and soil organic matter in various particle size fractions of soil contaminated with waste water [PDF]
, 2009 Only scarce field studies concern the consequences of natural soil organic matter (SOM) and metal interactions on SOM dynamics in soils. We investigated the interactions of four metals (Pb, Zn, Cu and Cd) with the SOM associated to five different size ...

Adsorption of heavy metals on sonicated activated sludge
Ultrasonics Sonochemistry, 2009 The objective of this work is to assess heavy metals fixation capacity on sonicated activated sludge. Ultrasonic treatment of sludge has lead to its desintegration and changes physico-chemical characteristics such as soluble chemical oxygen demand, proteins or particle size distribution.

High Performance Copper Based Metal Organic Framework for Removal of Heavy Metals From Wastewater
Frontiers in Materials, 2022 The biggest challenge of this century is the generation of wastewater which is released to the environment due to industrial expansion. Industrial development has caused the release of various pollutants including heavy metals such as Cd, Pb, and Cr into

Temporal and spatial trends for trace metals in streams and rivers across Sweden (1996-2009) [PDF]
, 2011 Long term data series (1996 through 2009) for trace metals were analyzed from a large number of streams and rivers across Sweden varying in tributary watershed size from 0.05 to 48 193 km(2).

Adsorptive Removal of Heavy Metals by Microalgae [PDF]
Journal of Phycological Research, 2019 In the present study, the optimization of immobilization structures along with Scenedesmus sp. and the determination of heavy metals (Ni, Cr) absorption rate have been investigated. Polymers in combination with salts were performed in alginate in order to study the stability of formed structures in cross linking agents.

Multi-metal contamination of a calcic cambisol by fallout from a lead-recycling plant [PDF]
, 2008 The present study deals with the impact of a lead-recycling plant on metal accumulation in soils, evaluated by a global pedological analysis. This general approach can be used on various contaminated sites to evaluate impact of an anthropogenic activity ...

Removal of mercury (II) from aqueous solution by using rice residues [PDF]
, 2013 Sorption potential of rice residues for Hg(II) removal from aqueous solution was investigated. Rice husk (RH) and rice straw (RS) were selected and treated with sodium hydroxide (NaOH).
