“…Oliveira Fernandes et al, (2021), in a scientometric analysis of research on mercury in soil, found that the 10 most cited articles were 4 from the journal Science of the Total Environment and one from Chemosphere [7]. It should be mentioned that [49] in their bibliometric analysis on hyperaccumulators for potentially toxic elements in the WoS database reported that International Journal of Phytoremediation ranked first, followed by Environmental Science and Pollution Research and Chemosphere, coinciding with the information reported in this study.…”

“…Volatile mercury is persistent and can be easily taken up by the plant system, accumulating in the food chain and entering the human body. The presence of reactive Hg in soil, under acidic conditions, low redox potential, and high concentration of organic matter, leads to the formation of methylmercury (MeHg) [7][8][9]. MeHg, the most common organic form, bioaccumulates efficiently in organisms and biomagnifies in the food chain.…”

Mercury is classified as one of the world’s most toxic and dangerous pollutants. It tends to bio-accumulate and biomagnify within the trophic chain and is persistent. Various approaches are available to remediate Hg-affected sites, including phytoremediation, which includes the use of plants to clean up contaminated environments. Phytoremediation of mercury contamination is at-tracting increasing attention because of its advantages: it is environmentally friendly, inexpensive, simple, and can improve soil fertility. In this report, VOSviewer, and Bibliometrix software were used to analyze 457 and 697 documents published from 2000 to 2023, retrieved from the data-bases WoS and Scopus, respectively. China, India, the United States, and Spain are the top four most productive countries. The largest topic area was environmental sciences, and the Chinese Academy of Sciences was the organization that contributed the most to the overall number of pub-lications. The keywords with the highest frequency, excluding phytoremediation and mercury in WoS, were heavy metals, accumulation, cadmium, soils, and phytoextraction. In Scopus, the most frequent keywords were bioremediation, heavy metals, soil pollution, bioaccumulation, biodeg-radation, and environmental. From the above analysis, we concluded that future research should focus on 1) finding native plants, 2) increasing remediation ability through assisted phytoremedi-ation, 3) studies of molecular mechanisms in plants with phytoremediation potential, and 4) ge-netic engineering applications. This study provides insight into trending themes and serves as a reference for future research.

“…Mercury (Hg), a potent neurological poison in fish, wildlife, and humans, is one of the most fatal pollutants threatening water bodies worldwide . In particular, postindustrial human activities, such as mining, have started to increase the mercury content of water by 3–10-fold . In 2017, the World Health Organization (WHO) declared that Hg is a toxic heavy metal and one of the “ten leading chemicals of concern” .…”

Gold nanoparticles (AuNPs) are useful nanomaterials as transducers for colorimetric sensors because of their high extinction coefficient and ability to change color depending on aggregation status. Therefore, over the past few decades, AuNP-based colorimetric sensors have been widely applied in several environmental and biological applications, including the detection of water pollutants. According to various studies, water pollutants are classified into heavy metals or cationic metal ions, toxins, and pesticides. Notably, many researchers have been interested in AuNP that detect water pollutants with high sensitivity and selectivity, while offering no adverse environmental issues in terms of AuNP use. This review provides a representative overview of AuNP-based colorimetric sensors for detecting several water pollutants. In particular, we emphasize the advantages of AuNP as colorimetric transducers for water pollutant detection in terms of their low toxicity, high stability, facile processability, and unique optical properties. Next, we discuss the status quo and future prospects of AuNP-based colorimetric sensors for the detection of water pollutants. We believe that this review will promote research and development of AuNP as next-generation colorimetric transducers for water pollutant detection.
