  • Description: Phytoremediation is an effective and low-cost method for the remediation of soil contaminated by potentially toxic elements (metals and metalloids) with hyperaccumulating plants. This study analyzed hyperaccumulator publications using data from the Web of Science Core Collection (WoSCC) (1992–2020). We explored the research status on this topic by creating a series of scientific maps using VOSviewer, HistCite Pro, and CiteSpace. The results showed that the total number of publications in this field shows an upward trend. Dr. Xiaoe Yang is the most productive researcher on hyperaccumulators and has the broadest international collaboration network. The Chinese Academy of Sciences (China), Zhejiang University (China), and the University of Florida (USA) are the top three most productive institutions in the field. China, the USA, and India are the top three most productive countries. The most widely used journals were the International Journal of Phytoremediation, Environmental Science and Pollution Research, and Chemosphere. Co-occurrence and citation analysis were used to identify the most influential publications in this field. In addition, possible knowledge gaps and perspectives for future studies are also presented.

  • Description: It is now widely recognized that natural vegetation and many economically important crop species are significantly harmed by a variety of compounds that are found in the atmosphere in the form of pollutants. These pollutants are the result of anthropomorphic actions, which lead to increasing concentrations of harmful chemicals in the atmosphere. These include oxides of sulfur and nitrogen, ozone (O 3), volatile organic compounds (VOCs), carbon monoxide, fluorides, and organic particulate matter (PM). With regard to the effect of these chemicals on crops and other vegetable species, the amount and type of damage depend on the concentration of gaseous pollutants in the atmosphere, the duration of the exposure time for the crops, and the nature of the growing season. Furthermore, the genotype of the plant governs the extent of damage caused by these atmospheric pollutants and can result in either acute or chronic damage. Polluting chemical contaminants have a variety of direct impacts on vegetation, which can include the plants' heat exchange parameters, together with their biological properties, antimicrobial activities, gene functions, and yielding characteristics. In addition, they frequently show modifications to the foliar structure and photosynthetic processes, which can cause an increase in the emission of reactive oxygen species, which are harmful to the plants' biological, physiological, and biochemical processes. These species can include hydroxyl radicals, singlet oxygen, and hydrogen peroxide, and, consequently, the health of crops, for example, will require remedial action, such as the neutralization of free radicals by the formation and coordinated action of enzymatic and nonenzymatic antioxidants. In order to contribute to such remediation processes, this chapter has focused on these air pollutants and their impact on vital physiological functions such as photosynthesis, respiration, carbon allocation, and the stomatal function of plants. © The Author(s).
