“…At the same time, the migration rate of Cd in the soil decreased from 45.8 to 19.0%, and the effect of the addition of FMSN on the soil properties was negligible [77]. In addition, FMSN reduced the leaching rate of Cd in the soil (36.0%) and bioavailability (54.3%); the concentration of Cd in crops decreased more than 50% [73].…”

“…Although the direct use of FMSN in food safety is new, the successes to date provide further evidence of the materials' wide-ranging applications, across diverse chemical conditions. However, perhaps, it is the use of FMSN to combat soil pollution that might be the materials' greatest contribution to our future food safety [73].…”

Innovative actions towards a pollution free-planet" is a goal of the United Nations Environment Assembly (UNEA). Aided by both the Food and Agricultural Organisation (FAO) and its Global Soil Partnership under the 3rd UNEA resolution, a consensus from > 170 countries have agreed a need for accelerated action and collaboration to combat soil pollution. This initiative has been tasked to find new and improved solutions to prevent and reduce soil pollution, and it is in this context that this review provides an updated perspective on an emerging technology platform that has already provided demonstrable utility for measurement, mapping, and monitoring of toxic trace elements (TTEs) in soils, in addition to the entrapment, removal, and remediation of pollutant sources. In this article, the development and characteristics of functionalized mesoporous silica nanomaterials (FMSN) will be discussed and compared with other common metal scavenging materials. The chemistries of the common functionalizations will be reviewed, in addition to providing an outlook on some of the future directions/applications of FMSN. The use of FMSN in soil will be considered with some specific case studies focusing on Hg and As. Finally, the advantages and developments of FMSN in the widely used diffusive gradients-in-thin films (DGT) technique will be discussed, in particular, its advantages as a DGT substrate for integration with oxygen planar optodes in multilayer systems that provide 2D mapping of metal pollutant fluxes at submillimeter resolution, which can be used to measure detailed sediment-water fluxes as well as soil-root interactions, to predict plant uptake and bioavailability.

T HE human activities include the agricultural, industrial and other activities. The agricultural sector is considered the main source for our life's supplies. However, the agricultural activities or practices might result many pollutants such as applied mineral fertilizers, pesticides, effluents from domestic and industrial sewages and vehicular emissions. Therefore, a remediation to remove or decrease the pollutants in soil and water is needed for the environment protection. This remediation has several classic strategies several years ago, but a promising and new approaches have been established particularly nano-remediation. This nano-remediation depends on the applied nanomaterials in removing pollutants from soils and water through nano-bioremediation and nano-phytoremediation. The most important nanomaterials that have potential in removing pollutants from contaminated soils and water are nano-silica, nano-zero-valent of iron, nano-sized iron sulfide particles, nano-ZnO and others. However, many challenges or open questions are still needing a justification because using nanomaterials in higher concentrations are toxic to plants and agro-environment. Are these nanomaterials stable under environmental conditions or will be converted into toxic ones or still need to be identified for sustainable nano-remediation? Is there any possibility to enter the nanomaterials or other toxic compounds the food chain through these plants? Therefore, a lot of further research is needed concerning the nano-remediation in removal the agro-pollutants.
