“…Similarly, when comparing with mean concentration of pre‐lockdown phase the reduction for each metal was in the following order: Fe (85.31%) > Al (69.08%) > Ni (66.51%) > Zn (65.7%) > Pb (59.71%) > Cd (41.43%) > Mn (41.02%) > Cu (26.16%). From Exhibit 8 , a significant association between Fe with Pb (r = 0.57) was observed, indicating that they originate from the same source (Jeričević et al., 2019 ). The intercorrelation between element and pollutants recommends the homogenous potential pollution sources and are explained in their respective sections.…”

Reduction in air pollution level was prime observation during COVID‐19 lockdown globally. Here, the study was conducted to assess the impact of lockdown on the elemental profile of PM 10 in ambient aerosol to quantify the elemental variation. To quantify the variation, phase‐wise sampling of air pollutants was carried out using the gravimetric method for PM 10 , while NO 2 and SO 2 were estimated through the chemiluminescence and fluorescent spectrometric method respectively. The elemental constituents of PM 10 were carried out using an Inductively Coupled Plasma Optical Emission Spectrometer and their source apportionment was carried out using the Positive Matrix Factorization model. The results showed that PM 10 , NO 2 and SO 2 reduced by 86.97%, 83.38%, and 88.60% respectively during the lockdown sampling phase. The highest mean elemental concentration reduction was found in Mn (97.47%) during the lockdown. The inter‐correlation among the pollutants exhibited a significant association indicating that they originate from the same source. The metals like Mn and Cu were found at a higher concentration during the lockdown phase corresponding to vehicular emissions. The comparative analysis of the elemental profile of PM 10 concluded that the lockdown effectuated in reduction of the majority of elements present in an aerosol enveloping metropolitan like Kolkata.

“…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.

“…Scholars have studied the sources of various air pollutants in different research areas and consider that the sources of sulfur oxides and nitrogen oxides are industrial waste gas and biomass (coal, petroleum, etc.) combustion [ 12 , 13 , 14 , 15 ], while the gas conversion process of particles, road dust, and the main emissions combustion of biomass are the main sources of atmosphere pollutants [ 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ].…”

Water-soluble anions and suspended fine particles have negative impacts on ecosystems and human health, which is a current research hotspot. In this study, coastal suburb, coastal urban area, coastal tourist area, and coastal industrial area were explored to study the spatiotemporal variation and influencing factors of water-soluble anions and total suspended particles (TSP) in Zhanjiang atmosphere. In addition, on-site monitoring, laboratory testing, and analysis were used to identify the difference of each pollutant component at the sampling stations. The results showed that the average concentrations of Cl−, NO3−, SO42−, PO43−, and TSP were 29.8 μg/m3, 19.6 μg/m3, 45.6 μg/m3, 13.5 μg/m3, and 0.28 mg/m3, respectively. The concentration of Cl−, NO3−, PO43−, and atmospheric TSP were the highest in coastal urban area, while the concentration of SO42− was the highest in coastal industrial area. Moreover, there were significantly seasonal differences in the concentration of various pollutants (p < 0.05). Cl− and SO42− were high in summer, and NO3− and TSP were high in winter. Cl−, SO42−, PO43−, and TSP had significant correlations with meteorological elements (temperature, relative humidity, atmospheric pressure, and wind speed). Besides, the results showed the areas with the most serious air pollution were coastal urban area and coastal industrial area. Moreover, the exhaust emissions from vehicles, urban enterprise emissions, and seawater evaporation were responsible for the serious air pollution in coastal urban area. It provided baseline information for the coastal atmospheric environment quality in Zhanjiang coastal city, which was critical to the mitigation strategies for the emission sources of air pollutants in the future.
