TL;DR: In this article, the authors investigated the relationship between the extent to which a trace metal is soluble in seawater and the degree to which it is held in exchangeable associations in non-remote marine aerosols.

TL;DR: In this article, the authors presented the first detailed data on aerosol concentrations of trace metals (Cd, Pb, Cu, Zn, Cr, Mn, Fe and Al) at the SE Mediterranean coast of Israel, and assessed their sources and fluxes.

TL;DR: In this article, the concentration of 20 elements (Mn, Fe, Na, Mg, Al, K, Ca, V, Co, Ni, Cu, Zn, Rb, Cd, Cs, Ba, La, Ce, Pb, Ni and Pb) were determined in 18 Fe-Mn nodules from two alfisols, which are subject to periodic waterlogging.

TL;DR: Interspecific variation in the body concentrations of zinc, copper and cadmium in crustaceans collected from clean and metal-contaminated sites is highlighted.
Abstract: Invertebrates accumulate trace metals in their tissues whether or not these trace metals are essential to their metabolism. Different invertebrates accumulate different trace metals to different degrees and accumulated concentrations vary greatly at tissue, organ and body levels (Eisler, 1981; Depledge and Rainbow, 1990; Rainbow, 1990a, 1993; Rainbow et al., 1990; Phillips and Rainbow, 1993; Chapter 8). Whether an accumulated concentration is high or low, therefore, cannot be assessed on an absolute scale, but the significance of an accumulated concentration depends greatly on the specific tissue and the specific invertebrate (Rainbow, 1987,1988, 1990a, 1993, 1996; Dallinger, 1993). To take one taxon as an example, tissue and body concentrations of trace metals vary greatly in crustaceans, even in the absence of anthropogenic input of trace metal contaminants (Bryan, 1968, 1976; Moore and Rainbow, 1987; Rainbow, 1987, 1988, 1989, 1990a,b, 1993; White and Rainbow, 1987; Ridout et al., 1989). Table 9.1 highlights this interspecific variation in the body concentrations of zinc, copper and cadmium in crustaceans collected from clean and metal-contaminated sites.

TL;DR: In this article, trace metal sorption by coagulated humic acid and peat materials can be described macroscopically either as a complexation or a cation exchange phenomenon.
Abstract: Trace metal sorption by coagulated humic acid and peat materials can be described macroscopically either as a complexation or a cation exchange phenomenon. Model equilibrium constants or selectivity coefficients for trace metal sorption by H‐form humic materials are special cases of two general models which do not depend on the sorption mechanism. Sorption mechanisms can be elucidated by spectroscopic techniques, both optical and magnetic resonance, but no information about mechanisms can be inferred from equilbrium constants.
