Application of ion chromatography for the determination of inorganic ions, especially thiocyanates in human saliva samples as biomarkers of environmental tobacco smoke exposure

Meconium samples used to assess infant exposure to the components of ETS during pregnancy

“…The previously conducted studies indicate that the thiocyanate ion can be determined in biological fluids using ion chromatography. It was determined in samples of saliva (concentration range: heavy smokers 0.015-0.847 mg/g, 0.046-0.7 mg/g moderate smokers, passive smokers 0.046-0.277 mg/g) and in samples of semen (concentration range: heavy smokers 0.00004-0.058 mg/g, moderate smokers 0.00008-0.043 mg/g, passive smokers 0.00004-0.028 mg/g) [22,23]. Moreover, the results on thiocyanate ion determination in the samples of saliva collected from the mothers, Pearson's correlation coefficient values for the relationships between ion concentrations in the samples of meconium and maternal saliva and F-Snedecor and t-students test to ion concentrations in meconium samples are reported.…”

The Effect of Salivary Calcium and Fluoride Toothpaste on the Formation of KOH-Soluble Fluoride: In Vitro Study

“…No malo se zna o učincima pušenja na sastav sline, posebno na njezin anorganski dio. Nedavne studije pokazale su da pušenje duhana znatno utječe na kemijski sastav prirodne sline (10). Svrha ovoga preliminarnog istraživanja bila je ustanoviti razliku u ugradnji alkalno topljivih fluorida na površinu cakline iz sline pušača i nepušača, uz pretpostavku da postoji razlika u koncentraciji kalcija u slini.…”

“…(6) However, little is known about the effects of smoking on the composition of saliva and, in particular, on its inorganic constituents. Recent studies showed that tobacco smoking has an important impact on the chemical composition of natural saliva (10). The aim of this preliminary study was to assess the difference in fluoride uptake by enamel from a smoker's saliva and a nonsmoker's saliva, assuming the difference in salivary calcium concentration.…”

Sequential Injection Analysis of Thiocyanate Ions Using a Microfluidic Polymer Chip with an Embedded Ion-Selective Electrode

“…For these reasons, there is a need to develop a useful analytical method for the determination of thiocyanate, featuring high accuracy, high sensitivity, high selectivity and easy analytical operation. Existing determination methods for thiocyanate, including those based on spectrometry, 2,3 fluorometry, 4 atomic absorption spectrometry 5 and ion chromatography, 6.7 require expensive instrumentations. Furthermore, the procedures in these methods are time-consuming and complicated.…”
