“…NPs have also been proven eff ective for soil remediation; such is the case of nano-iron NPs that have been shown to remove organic pesticides from the soil with an effi ciency of 25-100% [31]. On the other hand, of even greater effi cacy are the metal-organic NPs that have also been used for water remediation [32].…”

Agrochemical contamination is a severe problem that damages the ecosystem and reduces the quality of life of the people exposed; to remedy this problem, nanotechnology is an attractive bioremediation alternative for these types of chemicals. This study emphasizes bioremediation actions such as investing in alternatives, for example, the method of photocatalysis using Titanium Dioxide (TiO2) and Zinc Oxide (ZnO), and alternatives that aid in the degradation of most chemicals such as sonolyisis or ozonolysis to improve their effectiveness are of great interest. In this paper, the uses of nano remediation to reduce the effects of chemicals in agricultural soil were reviewed and its use is highly recommended.

“…The plant extract was prepared according to the procedure reported elsewhere [21]. Briefly, twenty milliliters (20 mL) of filtrate of Mentha leaf extract was mixed with 5 mM silver nitrate solution in a 1:2 v/v ratio at 60 • C and heated using a microwave {INPUT: 230-240 V~50 Hz 1200 W (MICRO), OUTPUT: 700 W 2450 MHz (Boss international company)} set at 48 • C. A visible brown color change occurred within 2 min, which indicated the formation of NPs.…”

“…Through the green approach, NPs generally have a broad size distribution, because of the presence of several reducing species and a variety of capping agents in an extract, which necessitate control and optimization [16][17][18][19][20]. Another green approach involves the use of microwave-assisted reactions (MAR), which supports the biosynthesis of NPs by providing the high temperature needed for the nucleation process, thereby enhancing the reaction kinetics and reducing the reaction times and associated energy costs [21][22][23]. NPs produced through microwave heating have excellent crystallinity as microwaves provide great control over the morphology and shape of the nanostructured particles [21].…”

The removal of pesticide pollution is imperative, because of their high environmental load and persistence, and their potential for bioaccumulation in, and toxicity to the environment. Most pesticides are found to be toxic even at trace levels. AgNPs can be effectively used for the adsorption of pesticides, and the incorporation of the AgNPs onto a support polymeric membrane enhances their effectiveness and reduces the potential unwanted consequences of intentionally adding free nanoparticles to the environment. Here, silver nanoparticles (AgNPs) were synthesized using a reliable, eco-friendly, and one-step “green” method, by reacting Mentha Piperita (mint) extract with AgNO3 aqueous solution at 60°C in a microwave. The resulting high surface area nanoparticles are both economic and effective environmental remediation agents, playing a promising role in the elimination of aquatic pesticide pollution. Embedding the nanoparticles into a cellulose membrane at a low concentration (0.1 g) of AgNPs was shown to result in effectively adsorption of representative pesticides (Cypermethrin, Paraquat, and Cartap) within 60 min, while increasing the concentration of nanoparticles incorporated into the membrane further enhanced the removal of the exemplar pesticides from water. The high adsorption capacity makes the cellulose-AgNPs membrane an excellent substrate for the remediation of pesticide-polluted water.
