The relative scavenging abilities of suspended particulate oxides (SPOX), and organic matter (SPOM) for Cd, Zn and Cu were evaluated in a small, anthropogenically influenced river.

In addition, the factor most important in influencing the sorption density (Ad: metal concentration associated with a given phase divided by the concentration of that geochemical Cited by: Abstract. We examined particle size distributions of suspended particulate matter (SPM); physical and environmental influences on the observed distributions; and relationships between particle size and geochemical partitioning of metals, over the fall and winter period in a small urban river (Don River, Toronto, Ontario, Canada).Cited by: Trace metal composition of particulate matter of the Danube River There have been fewer studies of trace elements in river particulates, but both natural and anthropogenic sources Danube River (suspended) 13, 13, 34 −.

There have been fewer studies of trace elements in river particulates, but both natural and anthropogenic sources can be important. Many trace metals adsorb strongly on particles (Balistrieri et al.,Balistrieri and Murray, ) and thus they are preferentially associated with particulate matter in rivers (e.g.

The dynamics of trace metals and the complexation behavior related to organic matter in the interface between water and sediment would influence water quality and evolution in the lake system.

Mostofa, Sen Xu, Zhongliang Wang. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): It is possible that metal–organic complexation enhances the uptake of gaseous organic compounds and the solubility of metals in aerosols and atmospheric water.

We investigated potential atmospheric organic ligands and the enhanced uptake of hydroxy- oxo- and dicarboxylic acids as well as. Trace metal clean sampling and analysis techniques were used to examine the temporal patterns of Hg, Cu, and Zn concentrations in shallow ground water, and the relationships between metal concentrations in ground water and in a hydrologically connected river.

Hg, Cu, and Zn concentrations in ground water ranged from to ng L−1, to μg L−1, and. INTRODUCTION. Urban storm water is recognized as a major source of trace metal pollution to many of the nations waterways [].Because metals typically are associated with fine particles in storm water runoff [2, 4], they have the potential to accumulate in the sediments of downstream receiving mson and Morrisey [] reported that metals from urban watersheds.

Introduction. Industrial pollution has been and continues to be a major cause of environmental degradation. Numerous studies have already demonstrated that areas in close proximity to industrial activities are marked by noticeable contamination of air, soil, and water [1–3].Hence, such activities can affect the air we breathe, the water we use, and the soil we stand on and Cited by: Fig.
