The ubiquitous occurrence of microplastics (MPs) in terrestrial ecosystems has been a significant environmental issue attributable to their recalcitrance and ecotoxicological effects. This review synthesizes the state of knowledge on the contamination of the soil environment by MPs, including sources, transportation processes, adsorption onto soil components, and effects on ecological and human health. It is derived from various human activities and penetrates agricultural soils, urban soils, and natural environments. MPs notably change soil physico-chemical properties by modifying pH and porosity (~88 mg/kg). It suppresses enzymatic activity (LDPE MPs at 0.50% [w/w] β-glucosidase [~31%], urease [~14%] as well as dehydrogenase [~41%]) through adsorption and altering the soil microenvironment and disturbs biological indices of soil (~1000 mg/kg), thereby impacting nutrient cycling, soil fertility, and crop yield (PS at 50 mg L−1 in faba beans). MPs also interact, adsorb (through electrostatic binding), and co-transport heavy metals and pollutants, which increases the toxicity risk in the soil–plant system. In plants, uptake and translocation of MPs (through apoplastic, symplastic, and crack-entry pathways) are dependent on particle size, charge, and plant species. It has been documented in the edible parts, raising concerns about food safety. MPs' vertical and horizontal transfer is facilitated by soil organisms such as earthworms and insects, affecting ecological processes. Research on MNPs has risen from 2009 to 2025, emphasizing their detection in human tissues and their links to endocrine malfunction, reproductive issues, neurotoxicity, and carcinogenesis. This study highlights the immediate necessity for multidisciplinary research, sustainable plastic alternatives, and efficient mitigation strategies to protect health and ecosystems. © 2025 John Wiley & Sons Ltd.

Mushrooms are regarded as multifaceted, packed with nutrients featuring established health advantages. Ancient Greeks believed that mushrooms might give troops strength during battle. Romans and Egyptians referred to mushrooms as "Food of the God" and said they were a particular delicacy. There have been thousands of years of Chinese use of mushrooms as food and medicine. Among the top mushroom producers in the world are China, the United States, Italy, the Netherlands, and Poland. In addition to providing food, mushrooms are currently a solution to other issues facing people. Using mycoremediation, mushrooms also aid in the development of greener environmental restoration technologies. A key component of "clean technology" is the biotransformation and purification of water into valuable products, as well as increased productivity and minimal trash creation. Mycelia, a component of mycoremediation, serves as both a protein source and a bioremediation technique. The propensity of mushroom species to secrete a number of breaking down and oxidizing enzymes, which have attracted study interest in the farming of mushrooms and waste remediation sector, can be ascribed to their effectiveness in the generation of food protein (biomass/fruiting bodies) from junk. Food security, human health, and eliminating environmental pollution are the key issues that mushrooms aim to solve. All these characteristics of mushrooms make it essential to combine resources for more thorough research by multiple international technological and scientific agencies. The market global for mushrooms is expected to expand as a result of their potential nutritional and health benefits, including those for weight control, oral health, and cancer prevention. © 2024 Walter de Gruyter GmbH, Berlin/Boston.

The unrestricted release of various toxic substances into the environment is a critical global issue, gaining increased attention in modern society. Many of these substances are pristine to various environmental compartments known as contaminants/emerging contaminants (ECs). Nanoparticles and emerging sorbents enhanced remediation is a compelling methodology exhibiting great potential in addressing EC-related issues and facilitating their elimination from the environment, particularly those compounds that demonstrate eco-toxicity and pose considerable challenges in terms of removal. It provides a novel technique enabling the secure and sustainable removal of various ECs, including persistent organic compounds, microplastics, phthalate, etc. This extensive review presents a critical perspective on the current advancements and potential outcomes of nano-enhanced remediation techniques such as photocatalysis, nano-sensing, nano-enhanced sorbents, bio/phyto-remediation, which are applied to clean-up the natural environment. In addition, when dealing with residual contaminants, special attention is paid to both health and environmental implications; therefore, an evaluation of the long-term sustainability of nano-enhanced remediation methods has been considered. The integrated mechanical approaches were thoroughly discussed and presented in graphical forms. Thus, the critical evaluation of the integrated use of most emerging remediation technologies will open a new dimension in environmental safety and clean-up program. © 2024 Elsevier B.V.
