“…The composition of Al-Fe-rich particles was similar to that of oil and coal fly ash emitted from local sources such as oil-and coal-fired boilers ( Figure 5), and similar in composition to oil and coal ash as reported in the scientific literature [66][67][68][69][70][71][72][73]. This makes it possible to use these values as source diagnostic ratios for source apportionment, regardless of study area location.…”

The aim of this study was to select chemical species characterized by distinctly different proportions in natural and anthropogenic particulate matter that could be used as tracers for air pollutant sources. The end-member mixing approach, based on the observation that the chemical species in snow closely correlated with land use are those that exhibit differences in concentrations across the different types of anthropogenic wastes, was used for source apportionment. The concentrations of Si and Fe normalized to Al were used as tracers in the mixing equations. Mixing diagrams showed that the major pollution sources (in descending order) are oil, coal, and wood combustion. The traces of several minor sources, such as aluminum production plants, pulp and paper mills, steel rust, and natural aluminosilicates, were also detected. It was found that the fingerprint of diesel engines on snow is similar to that of oil combustion; thus, future research of the role of diesel engines in air pollution will be needed. The insufficient precision of source apportionment is probably due to different combinations of pollution sources in different areas. Thus, principles for the delineation of areas affected by different source combinations should be the subject of further studies.

“…However, lower concentrations of elemental sulfur and inorganic sulfides were also observed. Moreover, sulfate was found in greater concentration in PM 2 [25] They also mentioned that HFOA had a low degree of crystallinity. Mofarrah et al reported that the structure of HFOA carbon is graphitic and amorphous in nature.…”

“…Al-Degs et al reported that the particle size of HFOA was in the range of 21.2-91.5 μm, while the arithmetic mean diameter was around 70.5 μm. [25] Mofarrah et al reported that the HFOA particles were grey in color, highly porous (macro-to meso-pores), and spherical in shape with a wide range of particle sizes, from a few to several μm with a mean aerodynamic diameter of 53.49 μm. [26] It was also reported that the pores were located randomly on the individual particle surface, resulting from the gas explosion in the particles at the time of burning and the phase formation process.…”

Heavy fuel oil ash (HFOA) is generated as an industrial waste material during the combustion of heavy fuel oil in power/desalination plants. With increasing energy demands, a significant volume of HFOA is generated. It is generally disposed of in landfills, causing environmental pollution, as it contains several toxic elements. Recently, efforts were made towards developing strategies for reusing industrial waste materials and creating value-added products from the waste materials. Despite significant information available in the literature on the utilization of HFOA, there is still a need for a thorough and systematic review on the characterization and utilization of HFOA in various applications. Consequently, this paper aims to present a critical review of the literature on HFOA generation, its chemical composition, physical properties, morphology, and applications. It is encouraging to note that HFOA has been used in several potential applications, such as the preparation of activated carbon and carbon nanotubes, metal recovery, environmental pollutant removal, polymer composites and construction materials, etc. However, the development of several value-added materials utilizing HFOA and its applications in other areas such as coatings, cathodic protection systems, and phase change materialswould emerge as a new topic of research. It is expected that this review will act as a precursor for further research on the use of HFOA in industrial applications. Since the use of HFOA will lead to environmental, economic, and technical benefits, research in the utilization of this industrial waste material is highly recommended.
