Low-cost materials to face soil and water pollution

In this mini-review, the authors comment on selected papers focused on the use of low-cost materials to prevent/remediate environmental pollution (specifically, soil and water pollution). The authors have selected publications corresponding to the years 2021 and 2022, using the searching tools Scopus, Web of Sciences, and Google Scholar to find basic data about the papers, the countries where the researches were carried out, number of citations, and other details indicative of the relevance of the works. Overall, the field of research is receiving growing attention and efforts, providing useful data on classical and new low-cost materials, both raw and modified by means of low-cost procedures, which constitute a clearly interesting alternative to face environmental pollution currently and for the future.
