“…It has already been reported that bifenthrin is toxic to earthworms (PPDB 2020). Patra et al (2020) reported moderate to low level of risk of pyridalyl to earthworms in the tomato and cabbage field soils. Indoxacarb was also predicted to pose moderate to low level of risk to earthworms in the tomato field soil (Sakthiselvi et al 2020).…”

Termites are one of the major pests of sugarcane. Bifenthrin has label claim for use against sugarcane termites and is applied at the time of planting over the cane setts in the furrows. A thorough knowledge on the dissipation kinetics of bifenthrin in the soil and cane setts provides an insight into its dynamic behavior in the soil-plant-environment continuum, and hence, was studied in detail. The recoveries of the method adopted to determine the residues of bifenthrin in the soil, sugarcane setts, stem, and leaf were in the range of 92.78-98.19% at three levels of fortification ranged between 0.01 and 0.1 μg/g of matrix. At the recommended dose (100 g a.i./ha), bifenthrin was found to persist in the soil and cane setts up to 60 and 75 days after treatment (DAT) with the half-lives of 16.4 and 25.0 days, respectively. The dissipation kinetics of bifenthrin followed the biphasic model. At double the recommended dose, the residues persisted up to 75 DAT and reached below the detectable limit (< 0.01 μg/g) on 90 DAT both in the soil and setts. The half-life of bifenthrin was 22.0 days in the sandy clay loam soil and 17.6 days in/on the sugarcane setts. In the present study, dissipation by photolysis has been ruled out, as the treated setts were not exposed to sunlight. This could be one of the reasons for longer persistence of bifenthrin in the sugarcane setts up to 75 DAT with the half-life of more than 2 weeks. The bifenthrin residues were not detected in the leaf and stem of sugarcane plant throughout the experimental period. There could be harmful effects to earthworms (risk quotient > 1.0) due to the presence of bifenthrin residues in the soil of tropical sugarcane ecosystem.

“…ADI values of chlorantraniliprole and λ-cyhalothrin are 1.58 mg/kg bw/day ( European Food Safety Authority, 2012 ) and 0.02 mg/kg bw/day ( World Health Organization, 2015 ). Numerically, the RQ value is more than 1 indicates the chemical poses risk to the consumers ( Sanchez-Bayo et al., 2002 ; Patra et al., 2020 ; Botle et al., 2020 ).…”

“…The long-term risk assessment of intakes compared to pesticide toxicological data was assessed by calculating the risk quotient (RQ), dividing the EDI by the relevant acceptable daily intake (ADI) nization, 2015).

Pigeonpea ( Cajanus cajan L.) is an annually cultivated food and forage crop, attacked by a large number of pests mainly pod borer ( Helicoverpa armigera ). For the control of this insect pest, a combination of broad-spectrum insecticides viz., chlorantraniliprole and λ-cyhalothrin have been in use to reduce the pod damage and increase crop production worldwide. Therefore, a field trial was conducted to study dissipation and persistence behavior of insecticides combination (Chlorantraniliprole 9.26 % + λ-cyhalothrin 4.63 % ZC) in/on pigeonpea at the recommended dose (RD) 30 g a.i./ha and double recommended dose 60 g a.i./ha (2RD). The quantitative analysis was performed using ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) for chlorantraniliprole and Gas chromatography with electron captured detector (GC-ECD) for λ-cyhalothrin. The Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) method was validated for its accuracy, precision and sensitivity. The chlorantraniliprole persisted upto 30 days and λ-cyhalothrin persisted upto 10 days at RD and 20 days at 2RD. The half-lives (DT 50 ) of chlorantraniliprole and λ-cyhalothrin were from 4.95 to 5.78 days and 2.48–4.33 days at recommended and double recommended dose in pigeonpea, respectively. However, residues of both insecticides measured from soil at 30 th day and harvest time were below the limit of quantification (LOQ). The waiting period deciphered for chlorantraniliprole and λ-cyhalothrin applied as combi-product was 9 days at recommended dose. Dietary risk assessment (Risk quotient<1) was performed on the basis of field trial suggested the application of chlorantraniliprole and λ-cyhalothrin as combi-product at recommended dose is safe for the consumers.

“…Nowadays, pesticides are widely used in the agricultural industry to reduce the impact of pests, weeds, and diseases in different crops, leading to increases in productivity and a higher quality of crops [ 5 ]. However, the improper use of pesticides involves risks for human health, as pesticide residues remain in fresh vegetables [ 6 , 7 , 8 ], food [ 9 ], soil [ 10 ], and water bodies [ 11 ] after harvest. Hence, the overuse and misuse of pesticides can greatly impact the environment [ 12 , 13 ] and poses a serious risk for human health, since short- or long-term exposure to pesticide residues may cause acute or chronic toxicity [ 14 ].…”

In recent years, the official authorities in Chile have reported transgressions in the maximum residue levels of pesticides in fresh vegetables. There is no official information about traceability, pesticide levels, and potential health risks. The aim of this study was to analyse pesticide residues and their corresponding dietary risk assessments in tomatoes from supermarkets in the Metropolitan Region. Pesticides were extracted using the Quick, Easy, Cheap, Effective, Rugged and Safe, QuEChERS method, and their concentrations were determined by using chromatography with HPLC-FL/UV and GC-MS/ECD/NPD, following the Analytical Quality Control and Method Validation Procedures for Pesticides Residues Analysis in Food and Feed, SANTE guide and ISO 17025:2017 standard. In addition, a dietary risk assessment was carried out by comparing Chilean data to international references. The results reported that 9% of the samples had pesticide residue levels above the maximum residue levels permitted in Chile. All the scenarios evaluated revealed the highest estimated daily intake and hazard quotients for methamidophos and chlorpyrifos. Both the active substances used were acetylcholinesterase inhibitors and were neurotoxic under chronic risk assessment. The results showed the highest chronic hazard index in the Chilean scenario for all age groups and genders. The evidence obtained revealed that methamidophos, methomyl, and chlorpyrifos should be restricted for their use in Chilean agriculture.
