“…Numerous studies have shown that nZVI can be used in the remediation of soils contamianted with Cr [17][18][19][20]. Our present study further confirms that both B-nZVI and S-nZVI greatly decreased Cr(VI) concentrations in soil, but that S-nZVI was overall more efective than B-nZVI, particularly at a higher dose (three-way ANOVA results, see Table 2).…”

“…nZVI has been used to reduce leaching of toxic metals through adsorption, complexation and chemical reduction processes [10][11][12][13][14][15][16]. Numerous studies have reported applications of nZVI in the remediation of soils contaminated with Cr [17][18][19][20] as well as other toxic metals [14][15][16] and organic contaminants [21]. However, bare nZVI readily becomes aggregated and oxidized in aerobic environments, leading to a low remediation efficiency.…”

Nano-scale zero-valent iron (nZVI) is among the most common nanoparticles widely used for the treatment of various environmental contaminants. However, little is known about the combined effects of nano-zero-valent iron (nZVI) and other soil amendments on soil remediation and plant performance. For the first time, we studied the remediation of Cr(VI)-contaminated soil using bare nZVI (B-nZVI) and starch-supported nZVI (S-nZVI) in combination with either biochar (BC) or humic acid (HA), and the consequent effects on plant growth and Cr accumulation. Both S-nZVI and B-nZVI decreased the contents of Cr(VI) and available Cr in soil, but increased available Fe content, with S-nZVI generally showing more pronounced effects at a higher dose (1000 mg/kg). B-nZVI exerted no inhibition and even stimulation on plant growth, but 1000 mg/kg S-nZVI produced significant phytotoxicity, resulting in decreased plant growth, low chlorophyll content in leaves, and excessive accumulation of Fe in roots. Each nZVI decreased shoot and root Cr concentrations. BC and HA produced synergistic effects with nZVI on Cr(VI) removal from soil, but HA decreased soil pH and increased the availability of Cr and Fe, implying a potential environmental risk. Addition of BC or HA did not alter the effects of either nZVI on plant growth. In conclusion, combined application of 100 mg/kg nZVI and BC could be an ideal strategy for the remediation of soil contaminated with Cr(VI), whereas high-dose S-nZVI and HA are not recommended in the remediation of agricultural soils for crop production or in the phytostabilization of Cr(VI).

“…The tool has several functions for bibliometric mapping, including collaboration analysis (e.g., authors, institutions, and countries/regions), topics analysis (e.g., keyword or terms), and citation-based analysis (e.g., bibliographic coupling and co-citations). Several papers have already applied VOSviewer to do bibliometric mapping analysis in environmental protection and safety-related topics, such as climate change [ 29 ], heavy metal removal [ 30 ], carbon emissions [ 31 ], contamination of water bodies [ 32 ], carbon capture and storage [ 33 ], soil remediation [ 34 ], safety culture [ 25 ], construction safety [ 35 , 36 ], process safety [ 37 ], domino effect [ 38 ], laboratory safety in universities [ 39 ], road safety research [ 40 ], etc.…”

This paper presents a bibliometric overview of the publications in the principal international journal Process Safety and Environmental Protection (PSEP) from 1990 to 2020 retrieved in the Web of Science (WoS) database to explore the evolution in safety and environmental engineering design and practice, as well as experimental or theoretical innovative research. Therefore, based on the WoS database and the visualization of similarities (VOS) viewer software, the bibliometric analysis and scientometric mapping of the literature have been performed from the perspectives of document types, publication and citation distribution over time, leading authors, countries (regions), institutions, the corresponding collaboration networks, most cited publications and references, focused research fields and topics, research trend evolution over time, etc. The paper provides a comprehensive and quantitative overview and significant picture representation for the journal’s leading and evolutionary trends by employing specific aforementioned bibliometric analysis factors. In addition, by reviewing the evolutionary trends of the journal and the proposed investigated factors, such as the influential works, main research topics, and the research frontiers, this paper reveals the scientific literature production’s main research objectives and directions that could be addressed and explored in future studies.

Recebido em 05/12/2019; aceito em 05/02/2020; publicado na web em 14/04/2020 APPLICATION OF ZERO-VALENT IRON NANOPARTICLES (nZVI) ON THE REMEDIATION OF CONTAMINATED SOIL AND GROUNDWATER: A REVIEW. The remediation of contaminated soil and water is a relevant topic, being the focus of intense research. The use of nanoparticles to degrade contaminants has been consolidated as a sustainable remediation technology, with promising results worldwide. In this scenario, the zero-valent iron nanoparticles (nZVI) which, due to their properties, prove to be an important element to be used in remediation techniques, in addition to being efficient and low cost. In this article the objective is to present a bibliographic review on nanotechnology applied to soil and groundwater remediation, especially the application of nZVI, considering its main characteristics, reactivity performance, pollutants that can be degraded, application and transport techniques and main advantages and disadvantages. Issues related to toxicity and factors related to in situ applications are also presented. It is considered the results that have been observed, there is feasibility for the research to intensify even more, due to the efficiency of this nanomaterial on pollutants present in soils and waters, and it is important to expand the studies in Brazilian soils, since most of the research is international, and it is not possible to directly transfer knowledge acquired from temperate soils to residual soils of tropical and subtropical climate.
