Abstract
The analysis of interference is a popular topic in sociolinguistics, and the researchers addressing it investigate the phenomena of interference with a special regard to mother tongue texts of speakers living in a linguistic minority. In order to analyse the phenomenon, one needs to be clear about the identity of the author of the particular text, in addition to the linguistic environment, the circumstances in which the phenomenon appears, etc., and this is particularly difficult in the case of historical texts. The most frequent interference phenomenon in Old Hungarian texts is the occurrence of Latin elements in the utterances of Hungarian mother tongue speakers; nevertheless, we can find other linguistic interferences as within the regions inhabited by Hungarians the speakers came in contact with and learned the language(s) of several communities with other mother tongues. In this study, I analyse Romanian words and phrases that appear in the texts of Hungarian-language testimonies given by Romanians living in Transylvania; these linguistic elements cannot be classified as regional borrowings in the Hungarian lexicon, and if they can, they were used by the Hungarian speakers for a very short period of time. Thus, my paper analyses phenomena of interference that are connected to mother tongue elements appearing in a foreign language text.

Abstract
The health risks associated with individual air pollutant exposures have been studied and documented, but in real-life, the population is exposed to a multitude of different substances, designated as mixtures. A body of literature on air pollutants indicated that the next step in air pollution research is investigating pollutant mixtures and their potential impacts on health, as a risk assessment of individual air pollutants may actually underestimate the overall risks. This review aims to synthesize the health effects related to air pollutant mixtures containing selected pollutants such as: volatile organic compounds, particulate matter, sulfur and nitrogen oxides. For this review, the PubMed database was used to search for articles published within the last decade, and we included studies assessing the associations between air pollutant mixtures and health effects. The literature search was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A number of 110 studies were included in the review from which data on pollutant mixtures, health effects, methods used, and primary results were extracted. Our review emphasized that there are a relatively small number of studies addressing the health effects of air pollutants as mixtures and there is a gap in knowledge regarding the health effects associated with these mixtures. Studying the health effects of air pollutant mixtures is challenging due to the complexity of components that mixtures may contain, and the possible interactions these different components may have.
