“…The concentration of metals (Pb, Cd, Cu, Zn, Fe, Mn) shows increased values of Fe (2.676 μg/m 3 ) and Mn (3.495 μg/m 3 ) compared to samples collected before and after the intense dust event (Table 3). These concentrations are also several times higher than those normally measured in the same area (Mifka et al, 2021). Normally, the concentrations of Fe and Mn, as well as Ca and Ti, are higher during Saharan dust advection than the annual mean values for a given area (Federici et al, 2018).…”

The uncharacteristically extreme outbreak of particulate matter took place over the Balkan region from 27 to 30 March 2020. Observations at air quality stations in Croatia recorded hourly PM10 concentrations up to 412 μgm−3. The meteorological analysis shows that the increase in PM10 concentrations was primarily due to the advection of dust from the deserts east of the Caspian Sea. The anticyclone north of Croatia and the cyclone over Anatolia formed a strong pressure gradient driving transport from the east. Both back trajectories and satellite products pointed to the dry Aral Sea as the main source of dust. A dust plume influenced the PM10 increase observed in Croatia, starting at the easternmost air quality stations. The modeling study shows that the vertical extent of the dust plume was up to ∼2 km. However, the chemical and morphological (scanning electron microscope analysis) composition of PM10 at the sites in the northeastern Adriatic Sea showed mainly the presence of Saharan dust. Prior to the advection of the Asian dust, the transport of Saharan dust, driven by Sharav cyclone, was observed in the PM10 values at several stations in the Adriatic Sea and on the Croatian mainland on 26 March 2020. Modeling results showed that the Saharan dust transport occurred at altitudes below ∼8 km. The mixing of the Asian and Saharan dust plumes over the Balkans was favored by the subsidence due to anticyclonic high‐pressure conditions and is the most likely explanation for the observed PM chemical and morphological results.

“…For the first time, the climatological aspects of dust transport and the annual cycle of dust deposition over the Adriatic Sea are evaluated. Despite some studies dealing with air‐quality monitoring for the eastern Adriatic (Alebić‐Juretić & Mifka, 2017; Cvitešić Kušan et al., 2020; Jeričević et al., 2016, 2019; Merico et al., 2020; Mifka et al., 2021; Telišman Prtenjak et al., 2009, 2013), this research is mainly focused on detecting the synoptic situations (modes) related to the most intense dust deposition events. For each synoptic mode, the goals were to examine and determine (a) dust emission intensity and source locations, (b) the atmospheric transport routes and spatial distribution of dust deposition in the Adriatic, (c) the threshold for dust deposition events (DDEs) for the entire study area, and (d) their annual averages.…”

Atmospheric mineral dust deposition plays an important role in providing nutrients to marine ecosystems. In this study, the climatology of dust deposition in the Adriatic Sea area was determined for the first time based on Modern‐Era Retrospective Analysis for Research and Applications, version 2 reanalysis from 1989 to 2019. The annual cycle of deposition exhibits two maxima: a stronger maxima in March–April and a weaker maxima in November. Wet deposition is a dominant process with a relative contribution to overall deposition from 67.35% to 88.53%. Deposition hot spots are along the Montenegrin coast and Otrant. The average contribution of dust deposition events (DDEs) is 16.5% (60.2 dy yr−1), with the strongest deposition during 1999–2009 and a positive trend in deposited mass during the study period. The effect of dust deposition on primary production is observed by a high level of oxygen saturation up to 250% (usually it is lower, up to 150%) in the stratified middle water layer (5–8 m) of the central Adriatic marine system (Rogoznica Lake) during an intense wet deposition episode. Such extreme values of oxygen saturation can be taken as an indication of biological activity related to an increase in phytoplankton abundance and activity, diatoms in particular.

“…This study has been conducted in collaboration with other research on the quantification of metals found in emissions from ships in Guanabara Bay, located in Rio de Janeiro, Brazil, by means of the MOUDI particle impactor (Micro-Orifice Uniform Deposite Impactor) for sampling. Although there are several studies on metal emissions from maritime transport, studies with multi-stage impactors are more limited (Gregoris et al, 2021 ; Mifka et al, 2021 ). The present work seeks to expand the information on the impact of maritime transport for measurements segregated by sizes of metals and to assist public policymaking for air quality with regard to ships, as their emissions need to be regulated at local, regional, and international levels.…”

In the world of growing maritime fleets, ships powered by fossil fuels are being widely used that are responsible for atmospheric emissions such as particulate matter (PM). When inhaled, these can cause serious injury to the body and affect internal organs, because the particle size is on a tiny scale. The International Convention for the Prevention of Pollution from Ships (MARPOL) regulates the standards for emissions from marine diesel engines. However, although they pose risks to human health and the environment, the metals present in PM are not covered by Brazilian national current legislation. This study is based on the results of sampling of PM in the atmosphere of Guanabara Bay, Rio de Janeiro, Brazil, by means of the MOUDI cascade impactor, followed by acid opening of the collected PM and subsequent chemical analysis by ICP-MS for the determination of Ba, Ca, Cd, Co, Cu, Cr, Fe, Mg, Mn, Ni, Pb, V, and Zn. In coarse particles, the mean values ranged from 0.11 ng m −3 for Ba to 24.9 ng m −3 for Fe; in fine particles, from 0.07 ng m −3 for Co to 25.0 ng m −3 for Fe; and in ultrafine particles, from 0.11 ng m −3 for Ba to 9.71 ng m −3 for Fe. Finally, the nanoparticles (Ba and Ca) were not detected and the maximum value obtained was 5.32 ng m −3 for Mn.
