“…AR has been a serious global problem for several decades in many regions, and the response of various ecosystems to AR stress and the profound negative effects have been studied [16,78,79]. Recently, many studies have focused on the metallic material electrochemical behavior (including corrosion behavior) [82][83][84][85], reinforced-concrete structure seismic behavior and performance [86], composites wear behavior [87,88], and element leaching behavior in metal-contaminated soil [89] under AR stress. Phosphorus-related research has also become attractive to researchers.…”

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.

“…HULIS extracted from weathered coal is a potential organic resource with abundant reserves and diverse grades . For example, HULIS extracted from weathered coal could serve as an adsorbent of the contaminant norfloxacin in environmental matrices and as a soil conditioner to reduce the concentration of heavy metals in soil . Other studies have shown that HULIS had positive effects on the dry biomass, root activity, and carbohydrate, lipid, protein and nucleic acid contents in maize .…”

BACKGROUND: Humic-like substances (HULIS) for use in controlling soil-borne diseases have been a research focus, but obtaining HULIS with high fungistatic activity via different extraction solvents has been challenging. In this work, three solvents were selected to extract HULIS from weathered coal. Inhibition rates against phytopathogens were used to evaluate the fungistatic activities of HULIS. Element contents (C, N, S, and O) and carbon-13-cross polarization magic-angle spinning nuclear magnetic resonance ( 13 C-CP-MAS NMR) spectra were used to evaluate the chemical composition. The relationships between the chemical compositions and fungistatic activities were assessed by redundancy analysis (RDA) and partial least squares regression (PLSR). RESULTS: The results showed that HULIS extracted with different solvents varied in the element contents, organic carbon structures and fungistatic activities. HULIS extracted with potassium hydroxide-ethanol had the highest content of C, the lowest contents of N and O, and the highest fungistatic activities (up to 71.86%). Consistent results through RDA and PLSR shows that C and S had positive effects on the fungistatic activity, while N and O had negative effects. Aliphatic C in HULIS had positive effects on the fungistatic activity, while the aromatic fraction and anomeric C had negative effects.CONCLUSION: In summary, different solvents extracted different fractions from weather coal. Mixed solvents with organic and inorganic solvents were more beneficial for extracting active fractions with higher fungistatic activity of HULIS from weather coal. The results of this work provide a good theoretical basis for the application of HULIS extracted from weathered coal. Fungistatic activityThe inhibition rates of HULIS against 13 phytopathogenic fungi were measured, and the results are summarized in Table 1. For J Chem Technol Biotechnol 2020; 95: 585-593

“…Considering the stable brown color of Vinasse, the removal of which is another problem in the treatment of these wastewater, the issue of treating wastewater of ethanol production factories has turned into a global problem (7). Heavy metal pollu- tion has progressively become a widespread problem with increasing industrial and agricultural activities (8,9). It is responsible for causing adverse effects on human health through food chain contamination (9,10).…”

Background: The wastewater of alcohol plants is called Vinasse. After conversion of molasses to alcohol and other derivatives, this compound must be removed as waste from the factory. If released without careful planning and proper management and supervision, this wastewater can cause serious and several social, economic, and environmental consequences. Therefore, it is very important to eliminate heavy elements before the waste goes deep into the soil or to underground water reservoirs.
