TL;DR: Bioaccumulation patterns showed that dust exposure is one of the major routes into human body for Cd, Pb, Co, Mn and Cr, while the burden of Zn, Cu, and Ni can be more linked to dietary sources.

TL;DR: More work is needed to investigate the speciation and bioavailability of Ca, Mg, Mn, W, and Se, and investigate whether chelating agents can increase trace metal bioavailability, and determine how trace metal dynamics change in an anaerobic membrane bioreactor (AnMBR).

TL;DR: In this paper, a model for quantifying the biological impact of particulate-bound metals in estuaries is proposed, which is strongly influenced by the partitioning of metals among sediment components at the oxidized sediment interface.

TL;DR: Trace elements are present in sea water at concentrations that range down to picomoles per litre (pmol 1-1) and even lower as discussed by the authors, and it is only recently that these have been fully overcome.
Abstract: Trace elements are present in sea water at concentrations that range down to picomoles per litre (pmol 1-1) and even lower. Such small concentrations pose extreme analytical problems, and it is only recently that these have been fully overcome. It is now known, for example, that contamination and the lack of sufficiently precise analytical techniques have led to reported concentration data that for some trace elements were too high by factors as much as 103. Because of this, real trends in the trace element data were sometimes totally masked by noise in the system, creating what Chester (1985) described as a ‘frustration barrier’, which prevented marine chemists from being able to relate trace metal distribution patterns to a consistent oceanographic framework. However, in a keynote review, Bruland (1983) pointed out that the mid-1970s had seen a quantum leap in our knowledge of the oceanic distributions of trace elements. This leap had become possible as a result of major improvements in both analytical and collection techniques, especially with regard to the elimination of sample contamination, which allowed the noise to be filtered out of the data. A selection of the new trace element concentration data in sea water is given in Table 11.1. At the same time that trace element concentration data were being refined, there were also advances in our understanding of the speciation of the elements in sea water.
