Abstract

Nuolat modernėjant pramonei vis labiau į akiratį patenka metalo apdirbimo darbinėje aplinkoje esantys organizmai ir jų galimai sukeliami apdirbimo procesų metu išsiskiriančių kietųjų dalelių, patekusių į gyvų organizmų vidų, neigiami padariniai. Smulkiausios kietosios dalelės, patekusios į žmogaus organizmą, patenka ne tik į plaučių bronchinio medžio smulkiausius taškus, tačiau gali užteršti ir kraujotaką, todėl tyrimo metu buvo nuspręsta identifikuoti kietųjų dalelių taršos pokytį galandinimo proceso metu, įvertinti darbinės aplinkos trūkumus ir pateikti efektyvius problemos sprendimo būdus.

Abstract

Automobilių transporto sukeliama vandens telkinių tarša yra aktuali aplinkosaugos problema Lietuvoje. Siekiant ją išspręsti, vykdomi įvairūs moksliniai tyrimai ir eksperimentai, kuriais įvertinamas transporto intensyvumo šalia vandens telkinių esančiose gatvėse poveikis vandens kokybei bei dugno nuosėdų sankaupų susidarymui. Šiame straipsnyje, remiantis atliktais moksliniais tyrimais, analizuojama, kokį poveikį Šešupės upės atkarpai Marijampolėje turi dvi ją kertančios tarptautinės „Via Baltica“ magistralės atšakos. Tyrimų rezultatai rodo, kad miesto gatvėmis važiuojantis sunkusis transportas kelis kartus padidina teršalų kiekį gatvių lietaus nuoplovose. Tyrimų duomenimis, į Šešupę išleidžiamos gatvių lietaus nuotekos yra nepakankamai išvalomos, todėl kelia pavojų upės ekologinei būklei. Rekomenduojama lietingą rudenį riboti tranzitinio sunkiojo transporto eismą miestų gatvėmis nukreipiant jį aplinkkeliais ir taip mažinant gatvių teršalų patekimą į vandenį.

Abstract

Particulate matters – affected air pollution and air pollution sources in the Northern part of Klaipeda are being analysed in the final work. The first part of the work focuses on the air pollution in Lithuania and worldwide, leteron methods and devices for measuring the concentration of the particulate matters in the air are being analysed. Earlier research works on this subject are being analysed together with various information sources. With the help of modern efficient air polution measurement devices, particulate matters – affected air pollution and air pollution causes in the Northern part of Klaipeda were examined. After collecting data on transport concentration in certain streets of the seaport, it was possible to do the modelling of segments of these streets. the resuls of the modelling are being compared with the results of the pre-existing research. The conclusions and recommendations of the final work are based on the analyses of the particulate matters – affected air pollution and itas spread in Klaipeda. the work consists of 8 parts; the Introduction, the Literature overview, the analyses of the air pollution estimation methods and devices, Particulate matters – affected air pollution analyses in Klaipeda city, the modelling of the particulate matters spread in the seaport, Conclusions, Suggestions and References. The volume of work is 119 p., excluding appendices, 56 illustrations, 17 Figures, 58 reference sources. Articles for publication and publications... [to full text]
