“…The chemical attack is often accompanied by erosion and wear of the metallic surface, which involves the physical degradation of the object [5]. In general terms, corrosion is promoted by the presence of water and oxygen, whereas their combination with acids accelerates the deterioration mechanisms, which are mainly responsible for the lifespan reduction of materials [6][7][8].…”

“…Searle and Mitchell [89] investigated the effects of diesel and coat particulate on Portland limestone, highlighting that the diesel particulate had worse effects on the surface erosion of this material, catalysing the formation of gypsum. The degradation of stone materials is therefore governed by many factors [7]. The conversion of limestone into gypsum is accelerated when compounds such as nitrogen oxides (NO x ) and other peroxides are present in the atmosphere [90].…”

“…On the other side, the frequency of occurrence of fluorinated side chains along the macromolecule strongly influence the photo-chemical stability [107]. More recently, a co-polymer, MMA(methyl methacrylate)_POMA (3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl methacrylate), and two ter-polymers, MMA(methyl methacrilate)_nBuMA(N-butyl methacrylate) _POMA (3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluoro-octyl methacrylate), and EMA(ethyl methacrylate)_nBu MA(N-butylmethacrylate)_POMA (3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluoro-octyl methacrylate), were synthesized via free radical polymerization, and their performance when used as protective coatings for stones have been evaluated in several articles, giving in some cases very promising results [104]. In other fields of application, C8 fluorochemicals and their derivatives have been eliminated from commercial products due to the risks on human health and environment [108].…”

In the last decades, the interest in the development of protective coatings for movable and immovable Cultural Heritage (CH) assets has decidedly increased. This has been mainly prompted by the raising consciousness on preservation requirements for cultural artefacts and monuments, which has consequently determined the development of new protective products. From acrylic resins used at the end of the last century to the up-to-date biomaterials and nanoparticles employed nowadays, the research has made a giant step forward. This article reviews the progresses, the technical challenges, and the most recent advances in protective coatings for archaeological metal, glass, and stone artefacts. It aims at offering a comprehensive and critical overview of the progressions in conservation science and displaying how research has optimized polymers in order to solve deterioration problems. Attention is given to recently developed materials, hybrid coatings, and corrosion inhibitors. This work seeks to provide a reference point for future research and to offer a wide-ranging introduction on the newly available material technologies to restorers and conservators.

“…NOx, a mixture of nitric oxide (NO) and nitrogen dioxide (NO2), or organic, i.e. volatile organic compounds (VOCs), yet the infamous PM2.5, that is a cocktail of chemicals (hydrocarbons, salts and other compounds given off by vehicles, cooking stoves and industry) and other natural components like dust and microorganisms [2]] in urban areas has serious health effects [3] and it is also a key factor in the degradation of surfaces of historical buildings and monuments [4].…”

Indoor and outdoor air pollution remains a major health risk for human beings. Nitrogen oxides and volatile organic compounds are amongst the major pollutant found outdoor. Thus, actions to diminish such risks and to provide safer outdoor / indoor environment are required. In this research work, we have decorated the surface of TiO2 with noble-metal oxides (Ag and/or CuxO) to improve the photocatalytic performances (removal of nitrogen oxides and benzene) under simulated solar-light irradiation. By means of advanced X-ray methods it has been shown that noble metals did not enter the TiO2 crystal structure, although they retarded the anatase-to-rutile phase transition and crystal growth. Photocatalytic activity was assessed in the gas-solid phase, monitoring the degradation of NOx and benzene, using a lamp simulating the solar radiation. Results showed that TiO2 modified with an Ag:Cu molar ratio equal to 1:1 (with Ag+Cu = 0.5+0.5 mol% = 1 mol%), was that exhibiting best de-NOx and benzene removal performances.

“…Good air quality pertains to air which is clean, clear and free from gaseous and particulate pollutants. It is required for preserving the exquisite balance of life on Earth and preserving heritage areas (with monuments thereon) and ecology (Brimblecombe 2003;Ivaskova et al 2015;Turo et al 2016). In contrast, poor air quality can adversely affect human health, plants and animals and degrade the environment (Mohnen et al 1993;Ghio and Devlin 2001;Shindell et al 2012;Stocker et al 2013;Janssen et al 2013;Wu et al 2013;Burney and Ramanathan 2014;Forouzanfar et al 2015;Fuzzi et al 2015;Kelly and Fussell 2015) which in turn may complicate small-to large-scale interactions of various atmospheric parameters, namely physical, chemical, optical and meteorological, leading eventually to climate change and its deleterious repercussions (Colvile et al 2001; 1 Orru et al 2017).…”

PM 2.5 never crosses the safe limit of the National Ambient Air Quality Standards of Nepal (NNAAQS) in the monastic and control areas but either crosses the NNAAQS occasionally or remains in its vicinity at the other two locations. The PM 10 concentration frequently exceeds the safe limit in the industrial area but not in the other remaining areas. The analysis indicates the dominance of the impact of local sources and boundary layer thickness on the atmospheric loadings of the particulate matter. The daily average mixing ratio of surface ozone remains normally low at all the four observational sites although the mixing ratio of ozone at Panditarama Lumbini International Vipassana Meditation Centre is much lower than the NNAAQS but higher than that observed at Tilaurakot.
