Are more restrictive food cadmium standards justifiable health safety measures or opportunistic barriers to trade? An answer from economics and public health
(Elsevier, 2008)
In the past, Cd regulations have imposed trade restrictions on foodstuffs from some developing countries seeking to access markets in the developed world and in recent years, there has been a trend towards imposing more ...
Effect of cadmium on cortisol production and 11 beta-hydroxysteroid dehydrogenase 2 expression by cultured human choriocarcinoma cells (JEG-3)
(PERGAMON-ELSEVIER SCIENCE LTD, 2010-09)
Cadmium is a toxicant with known carcinogenic and endocrine disruptor effects. We have previously
reported that prenatal exposure to cadmium may induce low birth weight which is associated to
increased foetal exposure ...
Flow-through photometric sensor for the determination of cadmium at toe nanogram per millilitre level
(1993)
A sensor for the determination of cadmium based on retention of the Cdl4″ complex on a QAE Sephadex resin located in the flow-cell of a conventional photometric detector and on subsequent complex displacement reaction with ...
Cadmium-copper competitive sorption in soils
(Universita degli Studi di Pisa, Istituto di Chimica Agraria, 1992)
Wasterwastes of municipal and industrial origin used to irrigate farmlands contain heavy metals which are sorbed on the surfaces of soil particles. Among those metals are cadmium (Cd) and copper(Cu). The degree to which ...
Cadmium exposure during pregnancy reduces birth weight and increases maternal and foetal glucocorticoids
(2009)
Cadmium exposure induces low birth weight through unknown mechanisms. Since low birth weight is associated to foetal exposure to high glucocorticoids (GC) concentrations, we hypothesized that low birth weight induced by ...
Fetal growth restriction is related to placental levels of cadmium, lead and arsenic but not with antioxidant activities
(2009)
The objectives of this study were: to measure some essential metals and toxicants in placentas of mothers delivering neonates with fetal growth restriction, and to establish potential associations between environmental ...
Symmetry and thermodynamics of tellurium vacancies in cadmium telluride
(Elsevier B.V., 2019)
The equilibrium geometries and thermodynamic properties of anion vacancies in cadmium telluride, as predicted by density functional theory, are revisited using semilocal and hybrid density functionals. We find that stable ...
Synthesis of bifunctional receptor for fluoride and cadmium based on calix[4]arene with thiourea moieties
(Elsevier B.V., 2017)
© 2017 Elsevier B.V. A new calix[4]arene thiourea derivative bearing a benzothiazolyl moiety (L) was synthetized and characterized by single crystal X-ray, NMR and ESI-TOF. The binding ability of the bifunctional receptor ...
Performance of modified Lennard-Jones potential to seed ab initio calculations of small cadmium clusters
(2013)
Weakly bonded Cadmium clusters have, even for small number of atoms, many isomers that are stable structures. Before any attempt to use ab initio calculations on these clusters, a limited set of good possible stable isomers ...
Rice Grain Cadmium Concentrations in the Global Supply-Chain
(Springer, 2020)
One of cadmium's major exposure routes to humans is through rice consumption. The concentrations of cadmium in the global polished (white), market rice supply-chain were assessed in 2270 samples, purchased from retailers ...
