Spatio-temporal distribution of aerosols and volatile organic compounds in troposphere: libar and mass spectrometry

U disertaciji je prikazano istraživanje sprovedeno u cilju određivanja porekla, prostorne raspodele i dinamike isparljivih organskih jedinjenja i aerosola u urbanoj sredini Beograda. Baza podataka korišćena za analizu aerosola obuhvata višegodišnje masene koncentracije suspendovanih čestica PM10, podatke o njihovom hemijskom sastavu (sadržaj čađi, As, Cd, Cr, Mn, Ni, Pb, Cl-, Na+, K+, Mg, Ca, NO3 -, SO4 2-, NH4 + i benzo(a)pirena), meteorološke parametre i visinu planetarnog graničnog sloja. Podatke korišćene za analizu isparljivih organskih jedinjenja čine koncentracije 36 molekulskih masa izmerene masenim spektrometrom sa transferom protona (PTR-MS), koncentracije neorganskih gasnih oksida (NOx, NO2, NO, SO2 i CO), visina planetarnog graničnog sloja dobijena na osnovu Lidar merenja i meteorološki parametri. Detaljna analiza zagađujućih materija izvršena je primenom brojnih metoda, kao što su: polarna klaster analiza i CBPF za određivanje položaja i uticaja izvora u blizini mernog mesta; receptorski modeli PMF i Unmix za identifikaciju izvora i određivanje njihovog doprinosa izmerenim koncentracijama; TSA, TCA, PSCF i CWT modeli za utvrđivanje doprinosa transporta zagađujućih materija i geografskih oblasti iz kojih potiču; multivarijativne metode za prognozu emisije; i HYSPLIT model za određivanje disperzije prognoziranih epizoda velikog zagađenja. U disertaciji je predložen i nov pristup analizi transporta zagađujućih materija koji podrazumeva specifičnu selekciju i klasterizaciju reprezentativnih trajektorija i uklanjanje doprinosa lokalnih izvora. Rezultati istraživanja pokazuju da su koncentracije suspendovanih čestica u urbanoj sredini Beograda značajno više u odnosu na druge evropske gradove. Njihove varijacije tokom prethodnih dvanaest godina nastaju kao posledica različitih faktora, među kojima su najznačajniji prelazak na daljinski sistem grejanja i remont termoelektrana u okruženju, varijacije intenziteta saobraćaja, ali i promene meteoroloških uslova. Rezultati polarne klaster, CBPF i TSA analize pokazuju da su dominantni izvori suspendovanih čestica lokalnog karaktera. Doprinosi regionalnih izvora emisije menjali su se u zavisnosti od meteoroloških uslova i sezona, ali nisu prelazili 19% godišnjih srednjih vrednosti koncentracija.

The dataset used for the aerosol analysis include a multi-year database of PM10 mass concentrations, data on the chemical composition of the suspended particles (black carbon content, As, Cd, Cr, Mn, Ni, Pb, Cl-, Na+, K+, Mg, Ca, NO3 -, SO4 2-, NH4 + and benzo(a)pyrene), meteorological parameters and planetary boundary layer height (PBL). The database used for the VOC analysis includes concentrations of 36 molecular masses measured by means of protontransfer- reaction mass spectrometry (PTR-MS), concentrations of inorganic gaseous pollutants (NOx, NO2, NO, SO2 and CO), PBL height obtained by means of Lidar measurements and meteorological parameters. A detailed analysis of pollutants was performed by means of various methods such as: cluster analysis and CBPF for determining the location and influence of sources in the vicinity of the measurement site; PMF and Unmix receptor models for source apportionment and estimation of their contributions to measured concentrations; TSA, TCA, PSCF and CWT models for the assessment of the share of pollutant transport, as well as their geographical area of origin; multivariate methods for the purpose of emission forecast; and HYSPLIT model to determine the dispersion of forecasted high pollution episodes. Furthermore, the thesis proposes a new approach to the analysis of pollution transport, which implies the specific selection and clustering of representative trajectories and removal of local source contributions. Research results indicate that the concentrations of total suspended particles in an urban area of Belgrade are significantly higher than in other European cities. Over the past 12 years, their variations have been driven by numerous factors, predominantly by the transition to district heating system and overhaul of the neighbouring thermal power plants, variations in traffic intensity and changes in meteorological conditions. The results of bivariate cluster, CBPF and TSA analysis show that the dominant sources of PM10 are distributed in the vicinity of the measurement site. The contributions of potential regional emission sources varied depending on the meteorological..

Seasonal mortality variations of cardiovascular, respiratory and malignant diseases in the City of Belgrade

The main purpose of this paper is to examine seasonal variations in mortality resulting from cardiovascular diseases, respiratory diseases and cancer, as well as to provide a review of environmental factors underlying such phenomenon. The herein presented study was conducted on the territory of Belgrade based on the data on daily mortality rates obtained from the Institute of Public Health in Belgrade for the period 2009-2014, as well as the data on annual mortality rates provided by the Statistical Office of the Republic of Serbia for the period 2000-2014. The analysis of mortality variations was performed by the use of Theil-Sen method, smooth trend method and cubic spline interpolation, whereas desriptive tools, such as winter/summer ratio and dissimilarity index, were used to examine the seasonal pattern. According to the Institute of Public Health, over 113430 deaths were registered in Belgrade area for the period 2009-2014, out of which 53.25% is attributed to cardiovascular diseases, 4.01% to respiratory diseases and 27.50% to cancer. The annual mortality rates caused by cardiovascular diseases and cancer on the territory of Belgrade are among the highest ranking in Europe. The leading causes of death in the observed period included: cardiomyopathy, heart attack and stroke with accompanying complications, breast cancer in women, prostate and colorectal cancer in men, lung and bronchus cancer for both genders, and chronic obstructive pulmonary disease. Cardiovascular and respiratory mortality rates are significantly higher among people aged 65 and over, whereas more than one third of deaths caused by cancer is observed among younger people aged between 45 and 64 years. Research results show that seasonal variations were most pronounced in mortality resulting from cardiovascular and respiratory diseases, with highest mortality rates recorded in February and March and lowest during the summer season. Also, the number of deaths due to cardiovascular diseases increased twice, namely at the end of June and October, which is assumed to be the result of sudden temperature changes. Nonetheless, no such seasonal variations were observed in mortality caused by cancer. Seasonal variations in mortality resulting from cardiovascular diseases also indicate gender differences, which is why sudden temperature changes in interim periods affect more women than men. As regards deseasonalized trend, mortality caused by cardiovascular diseases stagnates, while mortality caused by cancer and mortality caused by respiratory diseases records moderate to severe increase. This is a uniform trend in almost all municipalities in Belgrade, with average mortality rates being higher in central zones than in suburbs over the last 15 years, particularly mortality caused by cancer. A slight increase in the overall mortality can also be attributed to aging of the population, which cannot be verified due to lack of available accurate data on the average age structure of Belgrade population for the observed period. A better understanding of seasonal variations in mortality caused by chronic non-communicable diseases can contribute to improving the population health care and rising awareness of the population concerning greater health care in changeable weather conditions due to global warming and climate change. These findings can also enhance preventive action on environmental risk factors that are not limited exclusively to weather conditions, such as air pollution

Quantification and mechanisms of BTEX distribution between aqueous and gaseous phase in a dynamic system

In this study an analytical system was developed for determination of quantitative characteristics of BTEX distribution between gaseous and aqueous phase. Dynamic dilution system was coupled with Proton Transfer Reaction Mass Spectrometer (PTR-MS) to provide conditions for partitioning between the two phases resembling the interactions during rainfall. The amount of the target species retained in water were significantly higher than suggested by theoretical predictions indicating that dissolution is not the major mechanism of gaseous BTEX uptake in aqueous phase. Distribution coefficients and enrichment factors were calculated, and the possible mechanisms of partitioning were considered. As concluded, the interfacial adsorption and van der Waals interactions play significant role, whereas hydrogen-bond interactions have no major contribution to BTEX partitioning.
