“…Although chromium (Cr) exists in a variety of oxidation states, the most stable forms are +3 and +6 . Humans require chromium in its +3 form because of its unique nutritional and biological properties . Heavy metals are naturally occurring, but they are being produced and released into the environment at an alarming rate due to increased industrialization and urbanization (Table ).…”

Soil pollution from various anthropogenic and natural activities poses a significant threat to the environment and human health. This study explored the sources and types of soil pollution and emphasized the need for innovative remediation approaches. Nanotechnology, including the use of nanoparticles, is a promising approach for remediation. Diverse types of nanomaterials, including nanobiosorbents and nanobiosurfactants, have shown great potential in soil remediation processes. Nanotechnology approaches to soil pollution remediation are multifaceted. Reduction reactions and immobilization techniques demonstrate the versatility of nanomaterials in mitigating soil pollution. Nanomicrobial-based bioremediation further enhances the efficiency of pollutant degradation in agricultural soils. A literature-based screening was conducted using different search engines, including PubMed, Web of Science, and Google Scholar, from 2010 to 2023. Keywords such as "soil pollution, nanotechnology, nanoremediation, heavy metal remediation, soil remediation" and combinations of these were used. The remediation of heavy metals using nanotechnology has demonstrated promising results and offers an eco-friendly and sustainable solution to address this critical issue. Nanobioremediation is a robust strategy for combatting organic contamination in soils, including pesticides and herbicides. The use of nanophytoremediation, in which nanomaterials assist plants in extracting and detoxifying pollutants, represents a cuttingedge and environmentally friendly approach for tackling soil pollution.

“…Due to industrialization, clean water resources are becoming increasingly scarce. Water contaminants can be organic matter, microorganisms, metal particles, and others, which are extremely harmful to humans [ 121 ]. The detection of contaminants using silver based SPR sensors has become a popular application currently.…”

A series of novel phenomena such as optical nonlinear enhancement effect, transmission enhancement, orientation effect, high sensitivity to refractive index, negative refraction and dynamic regulation of low threshold can be generated by the control of surface plasmon (SP) with metal micro-nano structure and metal/material composite structure. The application of SP in nano-photonics, super-resolution imaging, energy, sensor detection, life science, and other fields shows an important prospect. Silver nanoparticles are one of the commonly used metal materials for SP because of their high sensitivity to refractive index change, convenient synthesis, and high controllable degree of shape and size. In this review, the basic concept, fabrication, and applications of silver-based surface plasmon sensors are summarized.

“…Nanomaterials can also be carriers of toxic metals, making them more accessible to organisms (Kansara et al, 2022). Examples of these NMs are noncarbon NMs like iron oxide magnetite nanoparticles, metal oxide nanomaterials, layered double hydroxides, nanomembranes/fibers, and nano-polymer composites, all of them are related to heavy metal contamination of water and in environmental cleanings (Baby et al, 2022).…”

The accelerated development of modern agriculture in order to feed a growing world population is one of the main causes of contamination in soil, water, and air, causing diseases in animals and humans. Among the most common pollutants are nitrogenous fertilizers, pesticides, hydrocarbons, and nanomaterials. As more food is produced, pollution increases, making it necessary the transition to sustainable agriculture, in which organic agriculture and precision agriculture stand out as ways to reduce emerging pollutants together with bioremediation. This review paper addresses three of the most common emerging pollutants in agriculture (pesticides, nanomaterials, and polycyclic aromatic hydrocarbons), their general description, biological effect, toxicity, norms of the maximum permissible values in Mexico, and ways to reduce them. Pesticides, nanomaterials, and polycyclic aromatic hydrocarbons are contaminants that can remain in soils damaging the ecosystem so strategies to reduce their effects include physical and chemical methods, the substitution of polluting products for organic equivalents, the use of plants and microorganisms alone or in combination as remedial agents and more recently nanotechnology and genetic engineering. The need for more food for the growing population is up today and directly related to the generation of more pollutants, deeper studies are needed to improve the effectiveness of these strategies and/or reduce their costs, in search of cleaner productions. From this review paper is possible to conclude that most of the pesticides used in the fields can affect biota, or are incorporated into the water table, the application of nanomaterials in agriculture, despite its usefulness, has also become a source of pollution because they can remain in the soil for long periods and polycyclic aromatic hydrocarbons have poor solubility so their removal is particularly difficult. In Mexico, even taking into account the damage caused by the pollutants described, there are currently no clear norms of the maximum permissible values for them.
