A new tetradentate Schiff base (SB), (E)-4-fluoro-2-(1-((2-(piperazin-1-yl)ethyl)imino)ethyl)phe-nol, was synthesized from condensation of 2-(1-piperazinyl)ethylamine and 5-fluoro-2-hydroxyacetophe-none. This ligand was ...
Concentrations of essential and toxic elements and health risk assessment in brown rice from Qatari market
(
Elsevier
, 2022 , Article)
Twenty-two brown rice varieties available in the Qatari market were analyzed for essential and toxic elements by ICP-MS. Found concentrations (µg/kg) were: As: 171 ± 78 (62–343), Cd: 42 ± 60 (4–253), Cr: 515 ± 69 (401–639), ...

1-(4-nitrobenzyl)-4-dimethylaminopyridinium chloride, [O2N-Ph-CH2-Py = N(Me)2]+[Cl]−, was made available in good yield and within one minute using microwave assisted reaction (MW). The ionic liquid product resonance structure ...
The Carcinogenic and Non-Carcinogenic Health Risks of Metal(oid)s Bioaccumulation in Leafy Vegetables: A Consumption Advisory
(
Frontiers Media
, 2021 , Article)
High levels of metal(oid)s in soil or food pose a severe health risk to humans. The potential toxicants find their way into the living systems via the food chain, following bioaccumulation in edible plants, including leafy ...
Systematic laboratory approach to produce Mg-rich carbonates at low temperature
(
Royal Society of Chemistry
, 2021 , Article)
Dolomite is a common Mg-rich carbonate in the geological record, but the mechanism of its formation remains unclear. At low temperature, the incorporation of magnesium ions into the carbonate minerals necessary to form ...
Immobilization of heavy metals by microbially induced carbonate precipitation using hydrocarbon-degrading ureolytic bacteria
(
Elsevier
, 2022 , Article)
Crude oil contamination introduces multiple threats to human health and the environment, most of which are from toxic heavy metals. Heavy metals cause significant threats because of their persistence, toxicity, and ...
