Analysis of MArkers of Exposure to Constituents of Environmental Tobacco Smoke (ETS)
PublicationTobacco smoke is a complex mixture of more than 4000 chemical compounds, many of which are harmful to human health. These compounds belong to various chemical classes, including amides, imides, lactams, carboxylic acids, aldehydes, ketones, alcohols, phenols, amines, hydrocarbons, ethers, and inorganic compounds. There are three types of tobacco smoke streams: the mainstream, the sidestream, and environmental tobacco smoke (ETS)....

Determination of thiocyanate as a biomarker of tobacco smoke constituents in selected biological materials of human origin
Publicationn order to protect human health, it is necessary to biomonitor toxic substances originating from tobacco smoke in biological materials sampled from persons with different exposures to tobacco smoke constituents. Thiocyanate anion is a biomarker of exposure to tobacco smoke components which is characterized by a relatively long half‐life in the human body, i.e. 6 days. In this work, we present the results of thiocyanate determinations...

Recent developments in biological sample testing methods for the confirmation of gestational exposure to tobacco smoke anddrugs of abused
PublicationSubstance use is most prevalent in reproductive-aged people also by women during pregnancy. In national prevalence surveys among women aged 15 to 44 years, 10.8 % of women reported using alcohol during pregnancy, 17 % reported smoking during pregnancy, and 4.4 % reported abusing any illicit substances during pregnancy. Virtually all illegal drugs, such as heroin and cocaine, pose dangers to a pregnant woman. Legal substances, such...

Środowiskowy dym tytoniowy - skład, oddziaływanie na organizm, problemy analityczne = Environmental tobacco smoke - chemical constituents, impact on human health, analytical problems
PublicationPalenie tytoniu jest przyczyną znacznego zanieczyszczenia powietrza wewnętrznego różnego typu pomieszczeń. Wiele związków chemicznych wydzielających się wraz z głównym i bocznym strumieniem dymu papierosowego wykazuje charakter rakotwórczy, a także wywołuje skutki toksyczne odległe w czasie. Różny stopień narażenia na szkodliwe składniki środowiskowego dymu tytoniowego obserwuje się zarówno u aktywnych, jak i biernych palaczy....

MECONIUM SAMPLES USED TO ASSESS INFANT EXPOSURE TO THE COMPONENTS OF ETS DURING PREGNANCY
PublicationThe aim of the study was to use meconium samples to assess fetal exposure to compounds present in environmental tobacco smoke (ETS). Material and Methods: In order to assess fetal exposure to toxic tobacco smoke compounds, samples of meconium from the offspring of women with different levels of tobacco smoke exposure, and the samples of saliva from the mothers were analyzed. Thiocyanate ion as a biomarker of tobacco smoke exposure,...

Determination of cyanide in urine and saliva samples by ion chromatography with pulsed amperometric detection
PublicationCommonly known as a highly toxic chemical, cyanide is also an essential reagent for many industrial processes. It naturally occurs in plant seeds as a cyanogenic glycosides. Another relatively common mode of cyanide exposure is inhalation of environmental tobacco smoke. This study concerns importance to determine cyanide ion in human biological samples. Urine and saliva samples were collected healthy volunteers exposed to tobacco...

Application of analytical procedure based on accelerated solvent extraction and ion chromatography technique for determination of thiocyanate and other inorganic ions in human placenta samples
PublicationExposure of a pregnant woman during pregnancy is a special case of exposure to toxic substances. Samples of placenta collected for the studies had been prepared with the technique of accelerated solvent extraction and later analyzed for the presence of thiocyanate ion and other inorganic ions, with the use of the technique of ion chromatography. The concentration of thiocyanate ion in placenta samples collected from active smokers...
