2231. Real-time characterization and source apportionment of fine particulate matter in the Delhi megacity area during late winterVipul Lalchandan, Varun Kumar, Anna Tobler, M.T.

Prévôt, Sachchida Tripathi, 2021, original scientific article Abstract: National Capital Region (NCR) encompassing New Delhi is one of the most polluted urban metropolitan areas in the world.
Real-time chemical characterization of fine particulate matter (PM1 and PM2.5) was carried out using three aerosol mass
spectrometers, two aethalometers, and one single particle soot photometer (SP2) at two sites in Delhi (urban) and one site located
~40 km downwind of Delhi, during January-March, 2018. The campaign mean PM2.5 (NR-PM2.5 + BC) concentrations at the two
urban sites were 153.8±109.4 μg.m-3 and 127.8±83.2 μg.m-3, respectively, whereas PM1 (NR-PM1 + BC) was 72.3 ± 44.0 μg.m-3
at the downwind site. PM2.5 particles were composed mostly of organics (43-44)% followed by chloride (14-17)%, ammonium
(9-11)%, nitrate (9%), sulfate (8-10)%, and black carbon (11-16)%, whereas PM1 particles were composed of 47% organics,
13% sulfate as well as ammonium, 11% nitrate as well as chloride, and 5% black carbon. Organic aerosol (OA) source
apportionment was done using positive matrix factorization (PMF), solved using an advanced multi-linear engine (ME-2) model.
Highly mass-resolved OA mass spectra at one urban and downwind site were factorized into three primary organic aerosol
(POA) factors including one traffic-related and two solid-fuel combustion (SFC), and three oxidized OA (OOA) factors.
Whereas unit mass resolution OA at the other urban site was factorized into two POA factors related to traffic and SFC, and one
OOA factor. OOA constituted a majority of the total OA mass (45-55)% with maximum contribution during afternoon hours
~(70-80)%. Significant differences in the absolute OOA concentration between the two urban sites indicated the influence of local emissions on the oxidized OA formation. Similar PM chemical composition, diurnal and temporal variations at the three
sites suggest similar type of sources affecting the particulate pollution in Delhi and adjoining cities, but variability in mass concentration suggest more local influence than regional.

2234. Bivališča Branislave Sušnik : dokumenti, besedila, podobe, pričevanjaBarbara Pregelj, Francisco Tomsich, scientific monograph Abstract: Antropologinja, arheologinja in jezikoslovka Branislava Sušnik (Medvode, Slovenija, 1920 ̶ Asunción, Paraguay, 1996) je eno od najpomembnejših imen intelektualne panorame sodobnega Paragvaja. Njene raziskave s področja zgodovine, jezikov in kultur številnih staroselskih ljudstev z juga Južne Amerike pa tudi njena razmišljanja o paragvajski identiteti sestavljajo enciklopedično in subverzivno panoramo, ki jo je šele treba odkriti. Njena življenjska pot je bila zapletena, njeni življenjepisi so polni protislovij in skrivnosti.
Ta v celoti dvojezična knjiga, prva monografija o njenem življenju in delu v slovenščini, prinaša rezultate interdisciplinarne raziskave, ki je potekala v različnih smereh in pri kateri so sodelovali pisatelji, raziskovalci in umetniki iz Paragvaja in Slovenije. Monografija prinaša še večinoma neobjavljene dokumente, besedila, podobe in pričevanja, ki skušajo vsaj deloma osvetliti življenje Branislave Sušnik, preizprašujejo njeno dediščino ter odpirajo nove možnosti prebiranja in udejanjanja njenega dela tako v Sloveniji kot v Paragvaju.
