Journal ArticleDOI
Assessment of fluoride concentration and daily intake by human from tea and herbal infusions.
TL;DR: The fluoride content in infusions of commercially available black, green, oolong, pu-erh and white teas was determined by ion-selective electrode and it is found that brewing time does increase the fluoride content, which ininfusions of black tea (5 min brewing) was higher than that in the other types of tea.
Journal ArticleDOI
High-performance liquid chromatography method for the simultaneous determination of thiamine hydrochloride, pyridoxine hydrochloride and cyanocobalamin in pharmaceutical formulations using coulometric electrochemical and ultraviolet detection.
TL;DR: The HPLC method for the quantification of Vitamins B1, B6 and B12 in pharmaceutical preparations and dietary supplements was successfully applied and characterized by wide concentration range, high sensitivity and good accuracy.
Journal ArticleDOI
Mercury and major essential elements in seals, penguins, and other representative fauna of the Antarctic.
TL;DR: The results suggest that several control mechanisms operate to maintain physiologically required levels that decreases any effect of heavy metal toxicants such as Hg and Cd.
Journal ArticleDOI
Oxidative stress parameters in rats exposed to fluoride and caffeine.
TL;DR: Caffeine administered intragastrically, as an antioxidant, was relatively efficient in alleviating the adverse effects of F on nitric oxide and total antioxidant status in serum, brain, liver and kidney of rats.
Journal ArticleDOI
Urinary concentrations of pyrethroid metabolites in the convenience sample of an urban population of Northern Poland.
TL;DR: The findings suggest wide exposure to pyrethroid insecticides in the Polish general population and a continuous need to further study the exposure to synthetic pyrethroids among the general population since there is a strong, increasing trend in their usage.
