Determination of selected polyaromatic hydrocarbons by gas chromatography–mass spectrometry for the analysis of wood to establish the cause of sinkin…
2014
Abstract The aim of this paper was to establish the cause of sinking of an old wooden vessel by polycyclic aromatic hydrocarbon (PAH) analyses because wood combustion is a source of PAHs. In particular, the molecular PAH patterns generated by each source are like fingerprints and it is possible to determine the processes that generate PAHs by studying their distribution in wood samples. The relative abundance of high molecular weight PAHs, together with the PAH compound ratios and with total index (proposed by us) has demonstrated that samples owe their PAHs in wood archaeological material to a predominant single mode of origin, i.e. combustion processes, therefore we can say that the sinki…
A Short Review of Simple Analytical Methods for the Evaluation of PAHs and PAEs as Indoor Pollutants in House Dust Samples
2022
Studies on indoor air quality are indispensable when considering that people spend approximately 85% of their time in confined environments. This short review mostly takes into consideration research that uses passive samplers to evaluate the quality of indoor environments (houses, school, cars, etc.). This short review summarizes most analytical methods to detect and quantify PAHs and PAEs in house dust used as a passive sampler. The objective of house dust analysis is to identify the presence, amount and distribution of specific hazardous substances in confined spaces and, if possible, to identify their sources. Household dust and the compounds present in it can enter the human body by in…

Pētera Šmita sarakste ar latviešu un lietuviešu filologu, etnogrāfu Eduardu Volteri
1917
Vēstulē P. Šmite pateicas par saņemtajiem materiāliem, lūdz atsūtīt citus, arī pazaudēto "Литовские свадебные народные песни = Lietuviškos svotbinės dajnos", kuras pierakstījis Antanas Juška (Антон Юшкевич), kā arī spriež par dažādu vārdu, piemēram, "bajārs" u.c. parādīšanos latviešu tautas folklorā, salīdzina tos ar citām valodām.
