Preconcentration method for trace metals in natural waters using 4-morpholine dithiocarbamate [PDF]

Journal of the Serbian Chemical Society, 2002
The optimum conditions were found for the preconcentration of trace metals in natural waters and model samples with standard metals concentrations by using 4-morpholinedithiocarbamate. The formed complexes were extracted with chloroform.

The concentrations of trace metals in plants from phosphogypsum waste heap in Wiślinka, northern Poland

E3S Web of Conferences, 2013
The aim of this work was determination of trace metals (Pb, Zn, Ni, Cu and Fe) in different plants collected in the vicinity of phosphogypsum waste heap in Wiślinka (northern Poland). The concentrations of trace metals were determined by two methods: AAS

Nanocomposites for Electrochemical Sensors and Their Applications on the Detection of Trace Metals in Environmental Water Samples

Sensors, 2020
The elevated concentrations of various trace metals beyond existing guideline recommendations in water bodies have promoted research on the development of various electrochemical nanosensors for the trace metals’ early detection. Inspired by the exciting

‘Brine Management through brine mining of trace metals’ for developing Secondary sources of nuclear fuel

Nuclear Engineering and Technology, 2023
The brine and seawater are important and largely untapped sources of critical trace metals and elements. The coupling of selective recovery of trace metals from seawater/brine with desalination plants gives an added advantage of energy credits to ...

Levels of trace metals and their impact on oocyte: A review

Taiwanese Journal of Obstetrics & Gynecology
Trace metals play a vital role in a variety of biological processes, but excessive amounts can be toxic and are receiving increasing attention. Trace metals in the environment are released from natural sources, such as rock weathering, volcanic eruptions,

Data of OECD soil and leachate resulting from irrigation with aqueous solution containing trace metals at increasing sodium concentration

Data in Brief, 2019
The accumulation of trace metals in soils is one of the main drawbacks when reclaimed waters are used as irrigation sources in agriculture. Such secondary water sources often also contain high levels of salinity and in detail sodium.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

A metabolome-wide association study of in utero metal and trace element exposures with cord blood metabolome profile: Findings from the Boston Birth Cohort

Environment International, 2022
Background: Exposure to metals lead (Pb), mercury (Hg), and cadmium (Cd) and trace elements selenium (Se) and manganese (Mn) has been linked to the developmental origins of cardiometabolic diseases, but the mechanisms are not well-understood.
