Abstract: In this work, we aim to clarify the empirical paradigm that bears on two aspects of syntactic locality in Slovenian. First, building on previous work, we investigate how robustly Slovenian observes the syntactic locality constraint precluding constituent sub-extraction out of subject noun phrases. Second, we ask whether Slovenian allows Left Branch Extraction in interrogative and non-interrogative sentences. To elucidate both issues, we conducted a magnitude estimation study, the results of which support our previous claim that there is a subject island effect in Slovenian. Furthermore, our results suggest that Slovenian disallows Left Branch Extraction, in contrast with some other Slavic languages. We also discuss theoretical consequences of our empirical findings.

Abstract: Plastic resin pellets are one of the main components of plastic fragments in the marine environment. They are small granules, generally cylinder or disk-shaped, with a diameter of a few millimetres used as industrial raw material for the production of plastic manufactured items. Resin pellets can be unintentionally released to the environment during manufacturing and transport, and can reach the ocean through processes such as surface run-off. Because of their environmental persistence, they are widely distributed in the oceans and on the beaches, all over the globe. Plastic pellets are also a sink of toxic compounds such as polychlorinated biphenyls (PCBs) that are present in the environment. During this thesis, we designed a protocol for extracting and analysing PCBs from marine plastic resin pellets. Although pressurized fluid extraction (PFE) is not commonly used in the field of microplastics, it is a reliable and efficient technique applied in other research areas. Thus, this method was tested in this work. PCBs were extracted from plastic pellets with PFE at 65 ºC and under 100 bar with hexane. Then, the extracts were concentrated to 1 mL, cleaned up on Florisil cartridge through solid-phase extraction. Prior to analysis on GC-ECD, the cleaned extracts were concentrated again. In the second part of the thesis, the following four extraction techniques of PCBs from plastic resin pellets were compared: Soxhlet extraction, PFE, ultrasonication and maceration. The obtain results have shown that the best efficiency and repeatability of extraction is achieved with PFE. In case of Soxhlet extraction, the results were unrepeatable. Maceration and ultrasonication had 40-45 % lower extraction efficiencies than PFE.
