Recent surveys have identified the presence of perchlorate, a natural compound and environmental contaminant, in forages and dairy milk. The ingestion of perchlorate is of concern because of its ability to competitively inhibit iodide uptake by the thyroid and to impair synthesis of thyroid hormones. A recent study established that milk perchlorate concentrations in cattle highly correlate with...

On the basis of lithium electrolyte mechanism, modified glassy polymers were developed by adding salts to poly(methyl methacrylate) (PMMA). This review summarizes how rheological and mechanical properties PMMA changed introducing various salts: perchlorate (LiClO4), trifluoroacetate (LiCOOCF3), trifluoromethanesulfonate (LiCF3SO3), nonafluorobutanesulfonate (LiC4F9SO3), bromide (LiBr). It was f...

Abstract A study is performed of the possibility using gas–liquid chromatography (GLC) to determine composition solutions lithium salts in aprotic dipolar solvents and solvate ionic liquids. The objects are perchlorate trifluoromethanesulfonate sulfolane complexes with obtained two ways: direct interaction initial components a given molar ratio common solvent its subsequent removal via evaporat...

Contamination of freshwater resources, fresh produce and some processed foods by perchlorate (ClO4 -) is a growing problem in the United States. The anion perchlorate is a naturally occurring as well as an anthropogenic chemical which occurs as salts of ammonium, sodium and potassium. The natural sources of perchlorate include Chilean caliche which is mined for use as a natural source of NaNO3 ...

Perchlorate has the potential to cause thyroid dysfunction by inhibiting iodide uptake by the sodium iodide symporter. Perchlorate-contaminated waters may lead to human exposure through drinking water and food chain transfer in crops by way of irrigation water. Perchlorate has been found in dairy milk collected nationally and internationally. This study was conducted to evaluate perchlorate in ...

The terahertz complex permittivity of the molecular plastic crystal succinonitrile (SN) or 1,2 dicyanoethane (N≡C−CH2−CH2−C≡N), doped with the lithium salts LiBF4, LiPF6, LiTFSI, and LiClO4 to form solid-state plastic crystal electrolytes, is measured and compared using temperature-dependent terahertz time-domain spectroscopy (THz-TDS). In contrast to the trends at low frequency, SN’s terahertz...

OBJECTIVE To review the epidemiological literature relevant to evaluating the risk of adverse effects on thyroid function associated with environmental perchlorate exposure. METHODS All studies investigating possible adverse effects of environmental perchlorate exposure on thyroid function in adults or in pregnant women and their newborns were critically evaluated. RESULTS There is no credi...
