“…The closer it is to 1, the higher the cluster homogeneity. Once it is above 0.5, the cluster result is highly reliable and rational [33,35]. The parameter of Mean (Year) reflects the average year of the terms in a specific cluster, which is valuable to determine whether the cluster is new or old [32].…”

“…In contrast, NO X emission keeps increasing because of the increasing amount of vehicles, and therefore makes greater contributions to the occurrence of AR, which has been changing Yu et al [32] applied CiteSpace to analyze the current state and explore the development trends in carbon emission trading area based on a co-citation analysis. Sun et al [33] provided an insight into stage-based characteristics of research on polycyclic aromatic hydrocarbons in food with cluster analysis and citation analysis using CiteSpace and HistCite. Ouyang et al [34] applied keyword co-word analysis and term co-occurrence analysis to investigate the knowledge structure of heavy metal loss from agricultural watersheds to aquatic systems and presented the global development trends.…”

With the continuation of industrialization and urbanization, acid rain (AR) has aroused extensive concern because of its potential negative effects on ecosystems. However, analysis of the current status and development trends in AR research area has seldom been systematically studied. Therefore, we motivated to conduct a bibliometric analysis of AR publications (1900–2018) using HistCite and CiteSpace software programs. Compared to traditional reviews by experts, this study offers an alternative method to quantitatively analyze and visualize the development of AR field at a large time scale. The results indicated that the overall concern of AR research studies had increased from 1900 to 2018. The most productive country was the United States, while the institution with the most publications was Chinese Academy of Sciences. “Environmental Sciences” was the most popular subject category, Water, Air, and Soil Pollution was the dominant journal, and C.T. Driscoll was the most prominent author in AR field. There were three hotspots in the field of AR, including analyzing AR status and its control policies in Europe, the United States, and China in the past few decades, investigating the ecological consequences of AR on plant histological, physiological, and biochemical traits, as well as surface water and soil properties, and the model application for quantitatively assessing AR and its effects on terrestrial and aquatic ecosystems at regional scale. Further, “behavior”, “phosphorus”, “fractionation”, “soil acidification”, “corrosion”, “performance”, “recovery”, “rainwater”, “trace element”, and “surface water” have been emerging active topics in recent years. This study can help new researchers to find out the most relevant subject categories, countries, institutions, journals, authors, and articles, and identify research trends and frontiers in the field of AR.

“…Necessary monitoring and detection methods should be developed to facilitate the governing, of which the applicable methods should also be green in order to alleviate the pollution pressure. PAHs (polycyclic aromatic compounds) derive from the incomplete combustion of coal, wood, gasoline, wood and agricultural waste, which are widely present in soils, rivers, atmosphere, and foods [4][5][6][7]. Long-term exposure under PAHs may lead to cancer [8][9][10].…”

Ionic liquids found a wide application in catalysis and extraction due to their unique properties. Herein, ethylene glycol dimethacrylate as the cross-linker and 1-vinyl-3- butylimidazolium tetrafluoroborate as functional monomer via thermally initiated free-radical polymerization was prepared as a novel copolymer solid phase micro-extraction (SPME) coating. A surface modified stainless-steel wire was implemented as the substrate. Factors affecting the extraction performances of the copolymer, including the molar ratio of monomers to cross-linkers, the amount of porogen agent, and polymerization time were evaluated and optimized. To evaluate the extraction performance, five commonly seen polycyclic aromatic hydrocarbons (PAHs) were taken as the analytical targets. The potential factors affecting extraction efficiency were optimized. The as-prepared SPME device, coupled with gas chromatography, was successfully applied for the determination of PAHs in water samples. The wide linear range, low detection limit, good reproducibility, selectivity, and excellent thermal stability indicate the promising application of the newly developed SPME fiber in environmental monitoring as well as in other samples having complex matrices.

“…These processes are investigated since the 1980's and their rate is clearly increasing. Figure 1 presents number of publications in the world in 1997-2017 concerning only PAH (Sun et al, 2019). It shows that their number exceeded 1100 but increased from 11 in 1997 to 127 in 2017.…”

“…It should be emphasised that in Poland still there are not many people who pay attention to threats which may occur during the process, which not always results from the lack of knowledge but often from ignoring the health threat (Zachara et al, 2017). (Sun et al, 2019) Despite clear, proved health threats, there is still scarce knowledge and awareness on the scope of these threats and on possibilities of their reduction, significant during processes where temperature of processing exceeds 120ºC. Frying, particularly grilling, that is performed improperly, may constitute a health hazard.…”

The objective of the paper is to review the present state of knowledge on health threats that occur as a result of some thermal processing of food products. Depending on the type and properties of raw materials and conditions of processes, carcinogenic, mutagen and genotoxic substances may be formed out of them, which may be treated as a process contamination. They are produced in processing plants, where their content is obligatorily controlled and organic, as well as in the conditions of food production in gastronomic units and households. The paper emphasises the second area of food processing, in particular, house-holds and popularised grilling processes, where there are no other possibilities of control of the threat level and awareness of people who prepare food and consumers is insufficient. The paper presents the most often occurring hazardous compounds, the most important regulations and admissible limits of consumption, as well as principles of thermal processing in a safe manner, and possibilities of limiting the levels of those substances in products
