Bibliometric Analysis of Phytotechnologies for Remediation: Global Scenario of Research and Applications

Abstract

Phytoremediation is often a low cost alternative to conventional remediation. To assess trends, a bibliometric approach using data from SciVerse Scopus, SciVerseHub, and GoogleTM Trends was used. Globally there is a linear increase in publications containing the word phytoremediation as a percent of all published papers in SciVerse Hub, with China, India, and the Philippines concentrating relatively more research in phytoremediation. Furthermore there was an inverse correlation between a country's Human Development Index (HDI) and a country's phytoremediation research output as a percent of total research. Results show a focus on phytoremediation in countries with low HDI values. This suggests that academic experts are available for advancing phytoremediation applications in countries where the majority of the effected population do not have the education, finances, and political leverage to obtain expensive conventional remediation efforts on their land. Phytoremediation can combine expert advice with affected parties commitment and labor to help mitigate the harms of polluted landscapes.

Phytoremediation of Heavy Metal Pollution: A Bibliometric and Scientometric Analysis from 1989 to 2018

“…The number of publications non-linearly increased over time. This same trend was observed in Koelmel et al [85]. The linear model can better describe the research trends in phytoremediation of HMs.…”

Progresses in restoration of post-mining landscape in Africa

“…For instance, a search of the Scopus database on ''phytoremediation'' (one form of restoration of mine wasteland) returns 9698 hits. On the global scale, research output in phytoremediation has been increasing at a faster rate than other restoration techniques over the past decade, particularly in Southeast Asia (Koelmel et al 2015). This large and spatially scattered body of knowledge has been systematically reviewed, covering a range of issues from ecological impacts , concepts and applications (Ali et al 2013), to restoration challenges (Pietrzykowski 2015;Mahar et al 2016;Nirola et al 2016) and potential restoration techniques (Rajkumar et al 2012;Paz-Ferreiro et al 2014;Sarwar et al 2017).…”

Self-Healing Asphalt: A Systematic Bibliometric Analysis for Identification of Hot Research Topics during the 2003–2018 Period

“…This leader country was followed by the Netherlands (43 papers and 19.8%, figures that implied that China doubled the production of the second-most productive country). Although the USA is usually found among the top contributors in most scientific and engineering fields [47,48], in this case, the American production (29 papers and 13.4% contribution) was ranked third, closely followed by the United Kingdom in fourth (24 papers and 11.1% contribution). Finally, the relevant production of a South American country like Chile must be highlighted, since it occupied the sixth position in the ranking, just after Spain.…”
