Lipid nanoparticles (LN) composed of biodegradable lipids and produced by green methods are candidates for the encapsulation of pesticides, potentially contributing to decreasing their release in the environment. From a safety-by-design concept, this work proposes LN for the encapsulation of insecticide active ingredients (AI). However, given the complexity of nanoparticles, ecotoxicological studies are often controversial, and a detailed investigation of their effects on the environment is required. Accordingly, this work aimed to produce and characterize LN containing the insecticide lambda-cyhalothrin (LC) and evaluate their safety to crops (Solanum lycopersicum and Zea mays), soil invertebrates (Folsomia candida and Eisenia fetida), and soil microbial parameters. The average particle size for LN-loaded with LC (LN–LC) was 165.4 ± 2.34 nm, with narrow size distribution and negative charge (−38.7 ± 0.954 mV). LN were able to encapsulate LC with an entrapment efficacy of 98.44 ± 0.04%, maintaining the stability for at least 4 months. The LN–LC showed no risk to the growth of crops and reproduction of the invertebrates. The effect on microbial parameters showed that the activity of certain soil microbial parameters can be inhibited or stimulated by the presence of LN at highest concentrations, probably by changing the pH of soil or by the intrinsic properties of LN.

Carbon nanomaterials (CNMs) are extensively employed in diverse fields and will inevitably be discharged into the soil to affect the soil microbial community. Numerous related studies have investigated the effects of exposure to CNMs on soil microbial communities, yet a consensus on their effects still needs to be discovered. This study conducted a global meta‐analysis by synthesizing 474 pairs of experiments from 20 screened publications in the literature from 2000 to 2022. The findings indicate that: exposure to CNMs significantly reduced microbial biomass carbon (MBC) by 17.02% and increased soil Shannon index by 2.63% (p < 0.05), which had no significant effect on soil microbial community composition and only reduced the proportion of Proteobacteria by 6.83%. The type of CNMs was one of the important influencing factors. The exposure to multi‐walled carbon nanotubes (MWCNTs) significantly reduced the soil MBC (p < 0.05). It reduced the proportion of Acidobacteria, Bacteroidetes, and Proteobacteria in soil, which had less effect on soil microbial diversity and was more suitable as a crop growth promoter. The exposure of single‐walled carbon nanotubes exhibited a comparable impact on soil microbial biomass as MWCNTs while significantly increasing soil microbial diversity. The exposure of fullerene (C60) had no significant effect on soil microbial biomass but significantly decreased microbial diversity (p < 0.05). In addition, soil pH, CNMs exposure dose, and exposure time significantly affect the effects of CNMs (p < 0.05). This research recommends that CNMs be used in high pH soil with high electrical charge intensity while avoiding exposure doses exceeding 1000 mg/kg and limiting exposure time to 50–100 days to minimize long‐term exposure effects on the soil. MWCNTs are less toxic to microbial communities compared with the other CNMs and are more suitable as crop growth promoters. In conclusion, CNMs show great potential for promoting agricultural production.
