Pesticide Residue Behavior and Risk Assessment in Celery after Se Nanoparticles Application

Abstract

This study investigates pesticide levels in celery, and compares their degradation, dissipation, distribution, and dietary risk after spraying with selenium (Se) nanoparticles. Abamectin, imidacloprid, acetamiprid, thiamethoxam, and lambda-cyhalothrin were sprayed at 1.6, 6.8, 2.0, 1.0, and 0.7 g a.i. ha−1 followed by a 2 g·ha−1 Se nanoparticle application during the growing period. Thiamethoxam, abamectin, imidacloprid, lambda-cyhalothrin, and acetamiprid in celery degraded following a first order kinetic model after 2 g·ha−1 Se nanoparticles application. With the exception of acetamiprid, the half-lives of thiamethoxam, abamectin, imidacloprid, and lambda-cyhalothrin were reduced from 2.4, 0.5, 1.2, 4.2 days without Se nanoparticles application to 1.4, 0.2, 0.9, 3.7 days with the addition of Se nanoparticles (2 g·ha−1), respectively. The chronic dietary exposure risk probability (RQc) and the acute dietary exposure risk probability (RQa) of celery after Se nanoparticles application were within acceptable limits for consumption except for abamectin.

Multiomics Explore the Detoxification Mechanism of Nanoselenium and Melatonin on Bensulfuron Methyl in Wheat Plants

“…An additional investigation found that the application of sodium selenite (Na 2 SeO 4 ) as a soil amendment resulted in increased levels of secondary metabolites (including total phenols, flavonoids, and anthocyanins) in Brassica juncea L. plants that were exposed to Cr . Kang et al showed that nano-Se application accelerated the decomposition of thiamethoxam, abamectin, imidacloprid, and λ-cyhalothrin in celery . Applying nano-Se (10 mg/L) via foliar reinforcement in tea plants has improved the adverse effects of pesticide stress caused by imidacloprid, acetamiprid, and difenoconazole.…”

“…38 Kang et al showed that nano-Se application accelerated the decomposition of thiamethoxam, abamectin, imidacloprid, and λ-cyhalothrin in celery. 39 Applying nano-Se (10 mg/L) via foliar reinforcement in tea plants has improved the adverse effects of pesticide stress caused by imidacloprid, acetamiprid, and difenoconazole. This improvement is achieved through the modulation and regulation of the antioxidant system, nutritional levels (specifically tea polyphenols and catechins), and secondary metabolism (total phenols and flavonoids).…”

Residue analysis and dietary risk assessment of abamectin in fresh corn, bitter melon, and Fritillaria

“…Abamectin was detected during field trials, and if fresh pods are consumed after harvest, the presence of these pesticides in food is anticipated to have a negative impact on human health. Several studies have assessed the risk of abamectin on various crops, including strawberries (Song et al, 2020), mangoes (Bian et al, 2020), okra (Ratnamma et al, 2020), celery (Kang et al, 2021), and wolfberry plants (Jing et al, 2021). However, there is currently no information in the literature regarding the risk assessment of abamectin application on fresh corn, bitter melon, and Fritillaria .…”

Effect of Selenium Nanocomposites Based on Natural Polymer Matrices on the Biomass and Storage of Potato Tubers in a Field Experiment

“…Nanotechnologies are being actively introduced into various spheres of human economic activity [18][19][20][21][22]. In particular, there are encouraging developments in the field of agrochemistry [23][24][25][26][27][28]. Innovative nanopesticides are nanomaterials developed for plant protection and characterized by the following properties: minimizing losses during the application, increasing leaf coverage, increasing stability, and reducing the amount of consumption of active substances.…”
