Special Issue Information

Dear Colleagues,

Nanomaterials have emerged as a revolutionary force in environmental science and technology, providing innovative solutions to pollution and degradation challenges. Escalating pollution, driven by industrialization and urbanization, demands urgent remediation. Nanomaterials, with their high surface area, reactivity, and versatility, are uniquely suited for tackling this crisis. They catalyze pollutant degradation, efficiently adsorb contaminants, and enable precise analysis. These materials also promote sustainable resource management and ecosystem restoration. Researchers across disciplines are harnessing nanomaterials to develop efficient, sustainable pollution control measures, offering hope for a cleaner and healthier environment in the face of escalating environmental challenges.

This Special Issue serves as an exclusive platform for researchers to comprehensively explore the multifaceted realm of nanomaterial applications in environmental remediation and pollution control. Encompassing a wide array of topics, it delves into critical areas such as photocatalysis for water and air purification, advanced oxidation processes (AOPs), the development of nanomaterials tailored for selective pollutant capture and analysis, and their application in enhancing both water and soil pollution control strategies. We encourage the submission of original research articles and systematic reviews. Researchers and experts are invited to share their cutting-edge research and insights in these nanomaterial-related fields, fostering advancements in environmental science and technology.

Arsenic (As)-contaminated soil reduces soil quality and leads to soil degradation, and traditional remediation strategies are expensive or typically produce hazardous by-products that have negative impacts on ecosystems. Therefore, this investigation attempts to assess the impact of As-tolerant bacterial isolates via a bacterial Rhizobim nepotum strain (B1), a bacterial Glutamicibacter halophytocola strain (B2), and MgO-NPs (N) and their combinations on the arsenic content, biological activity, and growth characteristics of maize plants cultivated in highly As-contaminated soil (300 mg As Kg−1). The results indicated that the spectroscopic characterization of MgO-NPs contained functional groups (e.g., Mg-O, OH, and Si-O-Si) and possessed a large surface area. Under As stress, its addition boosted the growth of plants, biomass, and chlorophyll levels while decreasing As uptake. Co-inoculation of R. nepotum and G. halophytocola had the highest significant values for chlorophyll content, soil organic matter (SOM), microbial biomass (MBC), dehydrogenase activity (DHA), and total number of bacteria compared to other treatments, which played an essential role in increasing maize growth. The addition of R. nepotum and G. halophytocola alone or in combination with MgO-NPs significantly decreased As uptake and increased the biological activity and growth characteristics of maize plants cultivated in highly arsenic-contaminated soil. Considering the results of this investigation, the combination of G. halophytocola with MgO-NPs can be used as a nanobioremediation strategy for remediating severely arsenic-contaminated soil and also improving the biological activity and growth parameters of maize plants.
