This model was reduced according to the selection criteria described above. Because neither the generalized additive modeling nor the linear modeling indicated any effect of salinity or [DOC], the dose–response curve analysis package in R was used (with the 3‐parameter Weibull function) to construct a concentration–response curve of normal larval development (corrected to 100% normal control development) versus Cu accumulation after 48‐h exposure (described in Deruytter et al ) to determine the EC50 and EC10, expressed as a Cu body burden.…”

Predicting copper (Cu) toxicity in marine and estuarine environments is challenging because of the influence of anions on Cu speciation, competition between Cu(2+) and other cations at the biotic ligand and the effect of salinity on the physiology of the organism. In the present study the combined effect of salinity and dissolved organic carbon (DOC) on Cu toxicity to larvae of Mytilus galloprovincialis was assessed. Two statistical models were developed and used to elucidate the relationship between Cu toxicity, salinity, and DOC. All models based on dissolved Cu indicate a decrease in Cu toxicity with increasing DOC concentrations, which can partly be explained by complexation of Cu(2+) ions with DOC. These models also indicate an increase in Cu toxicity (modeled with dissolved Cu or Cu(2+) activity) with increasing salinity, suggesting a salinity-induced alteration in the physiology of the mussel larvae. When based on Cu body burdens, neither of the models indicates an effect of salinity or DOC. This shows that the Cu body burden is a more constant predictor of Cu toxicity, regardless of the water chemistry influencing Cu speciation or competition and possible physiological alterations or changes in Cu speciation or competition.

“…For a wide range of elements it has been shown that the bioavailability tends to decrease when they are bound to organic matter, e.g. Pb (Van Sprang et al, 2015), U (Trenfield et al, 2011a, b), Ni (Weng et al, 2004;Deleebeeck et al, 2009), Cu (Deruytter et al, 2014) and Zn (De Schamphelaere et al, 2005). In addition, it is possible that the plants are able to regulate the uptake and/or disposal of certain elements.…”

From soil water to surface water – how the riparian zone controls element transport from a boreal forest to a stream

et al. 2017

Abstract. Boreal headwaters are often lined by strips of highly organic soils, which are the last terrestrial environment to leave an imprint on discharging groundwater before it enters a stream. Because these riparian soils are so different from the Podzol soils that dominate much of the boreal landscape, they are known to have a major impact on the biogeochemistry of important elements such as C, N, P and Fe and the transfer of these elements from terrestrial to aquatic ecosystems. For most elements, however, the role of the riparian zone has remained unclear, although it should be expected that the mobility of many elements is affected by changes in, for example, pH, redox potential and concentration of organic carbon as they are transported through the riparian zone. Therefore, soil water and groundwater was sampled at different depths along a 22 m hillslope transect in the Krycklan catchment in northern Sweden using soil lysimeters and analysed for a large number of major and trace elements (Al, As, B, Ba, Ca, Cd, Cl, Co, Cr, Cs, Cu, Fe, K, La, Li, Mg, Mn, Na, Ni, Pb, Rb, Se, Si, Sr, Th, Ti, U, V, Zn, Zr) and other parameters such as sulfate and total organic carbon (TOC). The results showed that the concentrations of most investigated elements increased substantially (up to 60 times) as the water flowed from the uphill mineral soils and into the riparian zone, largely as a result of higher TOC concentrations. The stream water concentrations of these elements were typically somewhat lower than in the riparian zone, but still considerably higher than in the uphill mineral soils, which suggests that riparian soils have a decisive impact on the water quality of boreal streams. The degree of enrichment in the riparian zone for different elements could be linked to the affinity for organic matter, indicating that the pattern with strongly elevated concentrations in riparian soils is typical for organophilic substances. One likely explanation is that the solubility of many organophilic elements increases as a result of the higher concentrations of TOC in the riparian zone. Elements with low or modest affinity for organic matter (e.g. Na, Cl, K, Mg and Ca) occurred in similar or lower concentrations in the riparian zone. Despite the elevated concentrations of many elements in riparian soil water and groundwater, no increase in the concentrations in biota could be observed (bilberry leaves and spruce shoots).

“…Fast‐scanning high‐resolution XRF provides semi‐quantitative distribution images of histologically relevant chemical elements . The size and resolution of these images are comparable with the results of classical histological microscopy and show characteristic functional organelles and structures (dermal layers, including connective tissue with, for example, lipocytes, fibrillary networks and glands; arteries, veins, capillaries and blood corpuscles; nervous axon bundles and fine dendritic processes), which can be clearly distinguished and imaged.…”

Large‐scale high‐resolution micro‐XRF analysis of histological structures in the skin of the pigeon beak

Histological analysis of biological structures in the avian beak is performed by means of large-scalehigh-resolutionmicro-Xray fluorescence analysis using a Maia detector system. Element maps of S, K, Ca, Fe and Zn of square millimeter sizes show distinct cellular and subcellular tissue structures in semi-thin sections with a resolution at the (sub-)micrometer scale. Non-destructive qualitative and quantitative evaluation of the respective trace elements can be performed on the tissue samples. The elemental maps are compared with conventional differential histological stainings of parallel sections. This method is discussed as a pre-examination tool for subsequent analysis of selected structural sites by diffractive and spectroscopic X-ray nanoprobe techniques and, after additional ultrasectioning, also by transmission electron microscopy.
