Linking trace element variations with macronutrients and major cations in marine mussels Mytilus edulis and Perna viridis

Marine mussels have long been used as biomonitors of contamination of trace elements, but little is known whether variation in tissue trace elements is significantly associated with those of macronutrients and major cations. Here, we examined the variability of macronutrients and major cations and their potential relationships with bioaccumulation of trace elements. We analyzed the ...

Histochemical properties and trace element concentrations in Parietaria L.from urban sites (Palermo, Italy)

We examined leaf and pollen histochemical properties in Parietaria L. and measured trace element concentrations in urban sites in Palermo, Sicily, affected by different stress valence levels. Urban pollution affects histochemistry macro-, micro-, and toxic element concentrations in Parietaria. We therefore decided to determine whether this plant can be used as a simple biomonitor or ...

Trace elements - controlling emissions from coal combustion

International and national legislation is increasingly being applied to trace element emissions. Although emissions have decreased for a variety of reasons in many developed countries, continued use of coal and more successful control strategies in other sectors mean that coal combustion is still a relatively important source of some trace elements, especially mercury. Existing pollution control ...

How are trace elements mobilized during the postweaning fast in northern elephant seals?

Northern elephant seal (Mirounga angustirostris) pups undergo a substantial intertissue reorganization of protein, minerals, and other cellular components during their postweaning development, which might entail the mobilization of associated contaminants.The authors investigated the changes in concentrations of 11 elements (Ca, Cd, Cr, Cu, Fe, Hg, Ni, Pb, Se, V, and Zn) in a longitudinal study ...

Alleviation of environmental risks associated with severely contaminated mine tailings using amendments: Modeling of trace element speciation, solubility, and plant assssccumulation

Tailings are considered one of the most relevant sources of contamination associated with mining activities. Phytostabilization of mine spoils may need the application of the adequate combination of amendments to facilitate plant establishment and reduce their environmental impact. Two pot experiments were set up to assess the capability of 2 inorganic materials (calcium carbonate and a red ...

Atmospheric concentration and fluxes of trace elements in Visakhapatnam City of India

Airborne PM10 samples were collected during winter and summer at three different sites in a coastal city, Visakhapatnam, India. Average individual trace element concentrations fluctuated between 19 ng m−3 (Cd) and 4,802 ng m−3 (Zn). Average trace element concentrations for winter were observed higher than those of summer. Dry deposition flux was estimated using metal concentration in ambient air ...

Determination of trace elements composition in dawadawa, a food condiment used in West and Central Africa

Dawadawa, obtained by alkaline fermentation of the matured dawadawa pod, is a culinary product used to enhance taste, flavour and intensify meatiness in soups, sauces and other dishes in West and Central Africa. It is believed to cure cholera, stomachache, diarrhea, bronchitis, pneumonia, leprosy, hypertension, and pain in the bones. The trace element contents of the fermented dawadawa pods were ...

Assessment of Trace‐Element Impacts on Agricultural Use of Water from the Dan River following the Eden Coal Ash Release

Catastrophic events require rapid, scientifically sound decision‐making to mitigate impacts on human welfareandthe environment. The objective of this study was to analyze potential impacts of coal‐ash‐derived trace elements on agriculture following a 35,000‐tonne release of coal ash into the Dan River at the Duke Energy Steam Station in Eden, NC. We performed scenario calculations to assess ...

Spatial differences in trace element bioaccumulation in turtles exposed to a partially remediated coal fly‐ash spill

Large‐scale releases of environmental contaminants from industrial facilities can cause considerable damage to surrounding ecosystems and require remediation. The expense and/or undesirable environmental side effects of physical removal may constrain remediation efforts. In 2008, approximately 4.1 million cubic meters of fly‐ash were released into the Emory River at a coal burning power plant ...

Element-enrichment factors in Parmotrema bangii and Cryptomeria japonica of Portuguese islands of the central North Atlantic

Owing to their abundance and ability to accumulate airborne elements, the epiphytic lichen Parmotrema bangii (Vain.) Hale and bark from its phorophyte, the Japanese cedar Cryptomeria japonica (L. fil.) D. Don, were chosen as atmospheric biomonitors and collected at five islands of the Azores archipelago, in the central North Atlantic - Sao Miguel and Santa Maria (eastern group); Terceira, Sao ...

Impact of Redox Cycles on manganese, iron, cobalt, and lead in Nodules

Redox processes are responsible for Fe and Mn segregation as Fe–Mn oxide coatings or nodules. These nodules are also trace element scavengers in soils. Redox processes are of particular importance in seasonally saturated soil containing naturally high concentrations of trace metals. We investigated the dynamics of Fe–Mn nodules and two associated trace elements, Co and Pb, under controlled redox ...

Trace elements accumulation in edible tissues of five sturgeon species from the Caspian Sea

This study is focused on twenty trace elements (Ag, Ba, Bi, Cd, Co, Cr, Cs, Cu, Ga, In, Mn, Mo, Pb, Rb, Sb, Sn, Sr, Ti, V, Zn) accumulation in muscles of five sturgeon species (Acipenser guldenstaedti, A. persicus, A. nudiventris, A. stellatus and Huso huso) from the southern part of the Caspian Sea. Moreover the relationships between some biological characteristics and the levels of the selected ...

The use of assemblage models to describe trace element partitioning, speciation and fate: A review

The fate of trace elements in soils, sediments and surface waters is largely determined by their binding to reactive components of which organic matter, metal oxides and clays are considered most important. Assemblage models, combining separate mechanistic complexation models for each of the reactive components, can be used to predict the solid‐solution partitioning and speciation of trace ...

Influence of carbon and lipid sources on variation of mercury and other trace elements in polar bears (Ursus maritimus)

In the present study, the authors investigated the influence of carbon and lipid sources on regional differences in liver trace element (As, Cd, Cu, total Hg, Mn, Pb, Rb, Se, and Zn) concentrations measured in polar bears (Ursus maritimus) (n = 121) from 10 Alaskan, Canadian Arctic, and East Greenland subpopulations. Carbon and lipid sources were assessed using δ13C in muscle tissue and fatty ...

Geochemical classification of groundwater using multivariate statistical analysis in Latvia

Multivariate statistical methods – principal component analysis (PCA) and hierarchical cluster analysis (HCA) – are applied to identify geochemically distinct groundwater groups in the territory of Latvia. The main processes observed to be responsible for groundwater chemical composition are carbonate and gypsum dissolution, fresh and saltwater mixing and ion exchange. On the basis of major ...

Environmental pollution and its effects on living matter

The present knowledge of elements essential for life is summarised. Pollution of air, water and soil can modify the availability of elements essential to living matter. Because of narrow range of adequacy for most species this can result in different abnormalities. Among human activities which mobilise large amount of elements, a significant role is played by energy production and ...

Zebra mussels (Dreissena polymorpha) as a biomonitor of trace elements along the southern shoreline of lake michigan

The invasive zebra mussel (Dreissena polymorpha) has become an accepted biomonitor organism for trace elements, but it has yet to be studied along the Lake Michigan shoreline. Likewise, the relationships between tissue concentrations of elements, organism size and sediment concentrations of elements have not been fully explained. This study found that a variety of allometric variables such as ...
