Application of ion chromatography for the determination of inorganic ions, especially thiocyanates in human saliva samples as biomarkers of environmental tobacco smoke exposure.
Environmental tobacco smoke is a major factor influencing the indoor air quality. Various toxic compounds emitted during tobacco smoking into the environment have a significant influence on the chemical composition of human biological fluids. The thiocyanate concentration in saliva is a biochemical measure, frequently used as an objective indicator of tobacco consumption. The goal of this study was to find significant relationships between salivary thiocyanates and other inorganic ions, which are constituents of natural saliva (Na(+), K(+), Mg(2+), Ca(2+), Cl(-), PO(4)(3-)) and to present the effectiveness of the proposed sample preparation procedure combined with ion chromatography technique for the determination of inorganic ions in human saliva samples collected from passive, moderate and heavy smokers.
