Public concern over the deleterious effects of atmospheric deposition (AD) has grown rapidly due to its adverse effects (teratogenicity, toxicity, and carcinogenicity) to human, animals, and materials. The aim of this review is to describe the effect of the AD on sculptures, measures for its reduction, and case studies on maintenances of sculptures against the AD. To this end, a step-by-step review is outlined to discuss the harmful effect of AD contamination on many important sculptures. The review paper is also extended to describe preventive steps to reduce AD on sculptures to help reduce the risks associated with AD.

“…The sampling apparatus was placed on the roof of a three-story building, 8 m away from a roof fence and 200 m above sea level. With an area of approximately 500 m 2 , this sampling location is a 'super' scientific monitoring station affiliated to Chongqing Forestry Bureau and has been used previously by researchers to observe atmospheric deposition of polycyclic aromatic compounds (Tian et al, 2017) and inorganic nitrogen (NO 3 and NH 4 + ) (Wang et al, 2018). In this study, PM 2.5 samples were collected on quartz filters (20×25 cm 2 , T2600, Pall Corporation, Port Washington, NY, USA) using a PM 2.5 sampler (ASM-1, Guangzhou Mingye Huanbao Technology Company, Guangzhou, China) at a flow rate of 300 L min -1 .…”

“…Deposition processes represent some important mechanisms of PAH removal from the atmosphere to the Earth’s surface and play a key role in their biogeochemical cycling in the environment, on local, regional, and global scales [ 9 , 10 ]. Deposition fluxes of PAHs are temporally and spatially variable, being the result of a large variation in PAH loadings over different regions and time periods [ 11 , 12 ]. It has been indicated that the size-dependent deposition velocity of semi-volatile compounds can vary greatly, mainly due to the fact that this parameter is closely linked to meteorological conditions, properties of the receptor surface, aerosol hygroscopicity and chemical composition [ 13 ].…”

This study combines an interseasonal variation of deposition profiles of fine-particulate-bound polycyclic aromatic hydrocarbons (PM2.5-bound PAHs) with source apportionment analysis. Comprehensive measurements were conducted in four representative periods of 2019 in the coastal urban region of the Baltic Sea in Poland. The mean daily deposition flux of Σ13PAHs was 229 ng m−2 day−1, which was lower than in other urban/industrial sites of Europe and Asia. The seasonal PAHs distribution exhibited a clear U-shaped pattern, reaching maximum values in January and December and the minimum in June. A strong influence of local/regional anthropogenic emissions and meteorological factors (precipitation, ambient temperature, wind regimes) was observed. The contribution of medium molecular weight PAHs (fluoranthene, pyrene, benzo(a)anthracene, chrysene) to the total sum of PAHs deposition fluxes increased from 24% in spring to 38% in summer, as a result of photochemistry, urban traffic, and shipping emissions. The highest contribution of 5- and 6-ring PAHs occurred primarily in autumn (55%), followed by winter (39%), spring (35%), and summer (26%). Benzo(a)pyrene (human carcinogenic compound) had a relatively high deposition flux in winter, which was almost 14 and 20 times higher than the values registered in spring and summer, respectively. The FLEXTRA dispersion model was used to study potential pollution regions for PM2.5-bound PAHs and to investigate changes in the PAH deposition regime in different seasons. This study reveals that the winter contribution of PAHs was mostly impacted by local urban activities (i.e., residential heating and coal-fired power plants). Winter PAH deposition fluxes were particularly associated with atmospheric particles transported from surrounding areas and industrially impacted regions of SE–S–SW Poland and Europe.
