Evaluation and implications of organophosphate pesticide residues in cabbage (Brassicaoleracea)

The improper application of pesticides in cultivating vegetables has resulted in the buildup of pesticide residues on vegetables. This study evaluated organophosphate pesticide residue levels in cabbage with specific objectives of investigating the varieties of organophosphate pesticides employed by farmers and their awareness, assessing residue levels on cabbage using semi-structured questionnaires, and determining the distribution of pesticide residues within the layers of the cabbage head using 50 cabbage samples randomly collected from farmers from 14 cabbage-producing communities. The findings indicated that 98 % of the farmers applied pesticides in the morning, whereas 24 % preferred evening application. Meanwhile, 22 % applied pesticides twice in a day. Also, 18 % combined pesticides, 40 % applied 20 ml during the application, 72 % chose a particular pesticide based on the expected efficiency, 46 % applied pesticides between 1 and 5 times in a season and 66 % sprayed between 7 and 14 days. Pyrinex 48 EC and Perferthion emerged as the predominant organophosphates, with usage rates of 10 % and 12 % respectively. Also, eleven (11) organophosphate pesticide residues were identified in the cabbage samples. Profenofos and chlorpyrifos exhibited the highest concentrations of pesticide residues, with levels reaching 0.02 mg/kg, with 56.6 % of the samples containing chlorpyrifos pesticide residue. Nevertheless, all the identified pesticide residues did not exceed the maximum residue limits for cabbage. The study analysis disclosed the presence of various organophosphate pesticide residues in the first 10 layers of cabbage. However, it was noted that the innermost layers might not contain any detectable pesticide residues. The findings highlight the need for farmers to use pesticides judiciously and follow recommended application practices to minimize vegetable residues.

Changes of 22 pesticide residues and 3 metabolites during the common processing of Auricularia auricula-judae

It is of great significance to investigate the changes of pesticide residues during processing procedures to ensure the accuracy of dietary risk assessment of pesticide residues. At present, there are few reports about the influence of household processing on pesticide residues in Auricularia auricula-judae. In this study, the changes of 22 pesticides and 3 metabolites during drying and rehydrating process in Auricularia auricula-judae were analyzed, and changes of dietary risk of the residues were assessed. The pesticide residue concentrations increased by 2.8–15.4 times after drying, indicating drying could increase the dietary risk of Auricularia auricula-judae. Different rehydrating conditions, including temperature, duration, and solutions were investigated and compared. The removal rates were the highest (67%–96%) when the Auricularia auricula-judae was rehydrated in clear water at 20 °C for 2h, and the dietary risk could be further reduced for some pesticides using 1.0% NaHCO3 solution for the rehydration. This study provided data for the dietary risk assessment and establishment of maximum residue limits (MRLs) for pesticides in the processed products of Auricularia auricula-judae.

Organophosphate pesticide residue impact on water quality and changes in macroinvertebrate community in an Afrotropical stream flowing through farmlands.

River Chanchaga has experienced significant agricultural practices around its catchment, which involved the indiscriminate use of pesticides. However, residents of the study area are not well aware of the negative impact of pesticides on water quality and macroinvertebrates. In this study, the first report on the influence of organophosphate pesticide contamination on the abundance of the macroinvertebrate community was provided. Sampling for the determination of organophosphate pesticide residues was carried out during the peak of the two seasons, while macroinvertebrates and physicochemical variables were observed for 6 months. We examined 11 organophosphate pesticide residues using gas chromatography coupled with mass spectrometry, 12 water quality variables, and 625 macroinvertebrate individuals. The concentration of recorded organophosphate pesticide residues ranged from 0.01 to 0.52 μg/L. From the Canonical Correspondence Analysis plot, malathion, chlorine, and paraffin show a positive correlation with Unima sp., Hydrocanthus sp., Chironomus sp., and Potadoma sp. At station 3, depth shows a positive correlation with Biomphalaria sp. and Zyxomma sp., indicating poor water quality as most of these macroinvertebrates are indicators of water pollution. Diuron and carbofuran show a negative correlation with Lestes sp. and Pseudocloeon sp., and these are pollution-sensitive macroinvertebrates. The total mean concentration of organophosphate pesticide residues was above international drinking water standards set by the World Health Organization except for paraffin, chlorpyrifos, and diuron. In conclusion, the observations recorded from this research are useful in managing pesticide applications around the river catchment.

Evaluation of Pesticides and Trace Metal Contaminants in Grains, Fresh Fruits and Vegetables from Odoluwa Market Ile Oluji; Ondo State Nigeria

Vegetables, fruits and grains are sources of food rich in vitamins, minerals, and fibers and also have beneficial ant oxidative effects Pesticides and trace metals typically contaminate these food products. Pesticides and trace metals are not biodegradable and have the potential for accumulation in different body organs, leading to unwanted side effects This study investigated the concentration of pesticide residues and some selected Trace metals in Vegetables, fruits and grains from Odolua market Ile-Oluji Ondo State. Samples were collected randomly from the market, representative portion of the samples was chopped into small pieces and blended using a blender..Quantitative determination of the pesticide for Herbicides, organochlorine and organophosphate was carried out using Gas Chromatography-Mass Spectrometer after liquid-liquid extraction. Trace Metal was determined using Inductively coupled plasma - optical emission spectrometry (ICP-OES). The results reveal the presence of pesticide residues in all the samples. The mean concentration of pesticides in the samples was below the maximum residue limits (MRs) value for World health organization (WHO) while some were higher. The results also shows that all the trace metals analyzed are present in the samples except for Cadmium which is below the detection limit while Lead and Cobalt are only detected in one sample each. Some concentrations of the trace metals were below the permissible limit for WHO while others were higher than the permissible limit.

Pesticide Residues in Organic and Conventional Agricultural Soils across Europe: Measured and Predicted Concentrations.

During the growing season of 2021, 201 soil samples from conventionally and organically managed fields from 10 European countries and 8 cropping systems were taken, and 192 residues of synthetic pesticides were analyzed. Pesticide residues were found in 97% of the samples, and 88% of the samples contained mixtures of at least 2 substances. A maximum of 21 substances were found in conventionally managed fields, and a maximum of 12 were found in organically managed fields. The number and concentration of pesticide residues varied significantly between conventional and organic fields in 70 and 50% of the case study sites, respectively. Application records were available for a selected number of fields (n = 82), and these records were compared to the detected substances. Residues from 52% of the applied pesticides were detected in the soils. Only 21% of the pesticide residues detected in the soil samples were applied during the 2021 growing season. From the application data, predicted environmental concentrations of residues in soil were calculated and compared to the measured concentrations. These estimates turned out not to be accurate. The results of this study show that most European agricultural soils contain mixtures of pesticide residues and that current calculation methods may not reliably estimate their presence.

Analysis of carbamate and organophosphorus pesticide in agricultural irrigation water by Liquid Chromatography - Mass Spectrometry

So far, the ultra-trace concentration of pesticide residues in environmental samples has challenged many analytical techniques, which are used to detect simultaneously organophosphorus and carbamate with various polarities. In this study, the OASIS-HLB column was modified by the reagent 1,8-Dihydroxy-2-(4-sulfophenylazo)naphthalene-3,6-disulfonic to enhance the retention of polar pesticides. Both real irrigation water and distilled water samples were applied to validate the determination method of ten carbamates and thirty-eight organophosphorus pesticides all together using LC-MS. According to the results, the linear interval of the method ranged from 1.0 to 100 µg/L, the detection limit was as low as 5.0 µg/L, the relative standard deviations presented less than 8.0%, and the recoveries were ranging between 60% and 112%. Moreover, in the irrigation water samples which were collected in both dry and rainy seasons in ten stations around the agricultural area, five compounds were found, including fenamiphos, terbufos, aldicarb, propoxur, and methiocarb. In the midst of those sampling areas, the Environmental Impact Quotient Field Use Rating of detected pesticide residues presented a high value - 272 at one station, which indicates a high risk for the surrounding environment as well as the local people’s health.

Impact of Washing and Fermentation on the Concentration of Pesticide Residues in Nigerian Staple Foods By IJISRT

The use of pesticides in agriculture is linked to accumulation of toxic compounds in the soil, in food, and its accumulation in animal and human tissues. Pesticide residues are deposits of pesticides that remain on or in agricultural produce after harvest or during storage. This work examined the effects various processing steps on the levels of methoxychlor, dieldrin, p,p’-DDE and α- chlordane residues in common staples; maize, rice, beans and cassava. The treatments administered included cold water washing, hot water washing, and fermentation for 3 and 5 days. The Quick, Effective, Cheap, Easy, Rugged and Safe (QuEChERS) technique was adopted for extraction of pesticide residues while gas chromatography tandem mass spectrometry was used for quantification of the residues in the samples. The processing steps applied had various effects on the level of residues ranging from - 149% to 100% reduction in level of pesticide; in rice processing, washing with hot water had the greatest impact in reducing methoxychlor (55.5-97.1%) and α- chlordane (95.5%). Fermentation for 5 days had the greatest impact in reducing methoxychlor residue from cassava (13.6-26.3%), while fermentation of maize for 3 or 5 days had similar impact in reduction of the level of methoxychlor (35.5-79.5% and 39.1-78.4% respectively) and α-chlordane (100% and 100% respectively). Hot water washing of beans was most effective in eliminating methoxychlor (98.4%), p,p’-DDE (100%), α-chlordane (100%) and dieldrin (100%). Reduction in hazard index was also observed with processing, as a result of reduction in amount of pesticide going into the diet.

An Evaluation of Insecticidal Trunk Injections for the Control of the European Cherry Fruit Fly Rhagoletis cerasi L. (Diptera: Tephritidae)

Cherry productivity is challenging in Europe due to the presence of the cherry fruit fly (Rhagoletis cerasi). Trunk injection is an alternative method of insecticide delivery that may improve pesticide performance in controlling pests. In our study, four pesticides (abamectin, acetamiprid, flupyradifurone, and cyantraniliprole) were investigated for trunk injection against R. cerasi. Acetamiprid trunk injection in a minimum dose of 0.56 g/tree was suitable for protection against the pest, the efficacy of the control was over 95%, and the pesticide residue concentrations in the fruits were below the maximum permissible limit in each experiment. The trunk injection and foliar spray of the same dose of acetamiprid were equally effective. In the case of the other three active ingredients (abamectin, flupyradifurone, and cyantraniliprole), the trunk injection method did not prove suitable for practical use due to various reasons, which are detailed in the manuscript.

The article is devoted to topical issues of utilization of unusable pesticides buried and stored in toxic waste landfills on the territory of the Russian Federation.Aim and objectives are analysis of sub-standard pesticides handling in the Russian Federation and development of a method of their utilization to obtain components for chemical production.The materials for the study were unusable pesticides.The sources of information were official documents containing analytical information on the quality of the natural environment (Annual State Reports on the State of the Natural Envi-ronment in the Subjects of the Russian Federation) and generalized results of thesurvey of Russian soils for the content of pesticide residues in them (Yearbooks «State of Pesticide Contamination of Natural Environmental Objects of the Russian Federation»).The paper analyzes the amount of unusable pesticides currently stored in the Russian Federation on the basis of official data.The qualitative composition of pesticides requiring utilization and stored in warehouses and landfills of the Russian Federation is considered.The principal scheme of utilization of unusable pesticides with obtaining components for chemical production, which can be used as secondary raw materials, is proposed.

Application of solid-phase microextraction and LCMS/MS for the detection of pesticide residues

Aiming at the organophosphorus pesticide residues in tea, a method integrating solid-phase microextraction and liquid chromatography-mass spectrometry was investigated for the detection of organophosphorus pesticide residues in tea. Firstly, the conditions in the process were optimized; then the method was established to analyze the organophosphorus pesticides in tea; finally, the method feasibility was verified by using actual sample determination. In terms of the results, the standard curve correlation coefficients of the solid-phase microextraction and liquid chromatography-mass spectrometry methods used in the study were greater than 0.99, while the average recoveries ranged from 72 to 109% with the relative standard deviations (RSDs) of less than 9.0%. This indicates that the method has a good linear range, low detection limit and high recovery. In the application validation in real samples, the concentrations of organophosphorus pesticide residues in tea were within the safe range. The method was validated to be suitable for the monitoring and control of organophosphorus pesticide residues in tea with low cost and simplified sample preparation.

Habitat type strongly influences the structural benthic invertebrate community composition in a landscape characterized by ubiquitous, long-term agricultural stress

ABSTRACT The importance of small waterbodies for biodiversity and ecosystem processes has long been neglected in research and policy development. However, because of their heterogeneous characteristics and habitat structures, these waterbodies are biodiversity hotspots for various aquatic and terrestrial organisms, as previously shown for rotifers, aquatic birds, and amphibians. Knowledge of benthic invertebrate community structures in small waterbodies is scarce. Thus, we performed a comprehensive field study of these structures in an agricultural landscape in the northeastern German lowlands. We obtained a dataset containing biological (taxon abundances) and chemical (pesticide residue and nutrient concentration) data as well as data on environmental parameters (e.g., conductivity and habitat type) for 111 samples. The dataset was analyzed using generalized linear models, permutational multivariate analysis of variance, and partial redundancy analysis to understand the relationships among benthic invertebrate communities, agricultural stressors, and environmental parameters. The factor that best explained structural community composition was habitat type. Pesticide and nutrient concentrations were of minor importance in our analysis. Because of the ubiquitous and long-term occurrence of the agricultural stressors, the structural indices used in benthic invertebrate biomonitoring were not sufficiently sensitive to provide information on the main environmental variables that shape macroinvertebrate communities.

Seasonal screening of pesticide residues in beehive products collected from different districts in Egypt

Pesticides are of immense importance in agriculture, but they might contaminate bees’ products. In this study, samples of honey, pollen, and beeswax were collected, seasonally, from apiaries in Toshka (Aswan), El-Noubariya (El-Beheira), and Ismailia (Ismailia) cities in Egypt. The pesticide residues were analyzed using the GC-MS after being extracted and cleaned using the QuEChERS method. Results showed that samples from El-Noubariya had great content of residues followed by Ismailia, and finally Toshka. Samples collected during fall and winter had the highest pesticide residue contents. Specifically, the phenylconazole fungicide group was repeatedly detected in all the examined samples along with organophosphate insecticides. Beeswax samples had the greatest amounts of pesticide residues followed by pollen and then honey samples. Chlorpyrifos (0.07–39.16 ng/g) and profenofos (1.94–17.00 ng/g) were detected in honey samples and their products. Pyriproxyfen (57.12 ng/g) and chlorpyrifos-methyl (39.16 ng/g) were detected in great amounts in beeswax samples from Ismailia and El-Noubariya, respectively. Yet, according to health hazard and quotient studies, the amounts of pesticides detected in honey do not pose any health threats to humans.

Determination of pesticide residue content in fruits and vegetables from Lagos, Nigeria.

Developing countries like Nigeria are increasingly employing pesticides to boost the productivity of their agriculture and food supply, despite the fact that doing so poses a health risk to the general populace. The purpose of this study was to assess pesticide residue levels in Lagos, Nigeria. A total of 18 samples from three neighbourhood markets were collected, and they were then examined for the presence of organochlorine (Endosulfan I, Pentachlorophenol, Heptachlor epoxide, and Endosulfan II) and organophosphate (Dichlorvos, Dimethoate, Phorate, and methyl parathion) residues. During the pre-treatment, the multi-residue Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS citrate) method with the addition of acetonitrile was used, and then samples were analysed using GC-MS. All of the samples contained dichlorvos, but the orange sample's concentration was below the limit of quantification, making quantification impossible. Dimethoate concentrations were below MRLs except waterleaf sample. With a concentration of 0.043 μg/mL, Waterleaf had the highest quantity of dimethoate in the sample. The findings of this study indicate that in order to safeguard the health of consumers, it is necessary to closely monitor organochlorine and organophosphate use nationwide, along with other related pesticides, and to test for pesticide residues in food products.

Biochemical Response of the Endogeic Earthworm (Balanteodrilus extremus) Exposed to Tropical Soils

This work evaluated the biochemical responses of the endogeic earthworm Balanteodrilus extremus exposed for 14 and 48 days (d) to soils collected from two tropical agricultural systems: maize-sorghum (MS) and soybean-sorghum (SS). A soil without agricultural management (WAM) and the use of pesticides was selected as a reference. The presence of organochlorine (OC) and organophosphate (OP) pesticide residues was quantified in MS and SS soils. Biomarkers of detoxification [glutathione S transferase (GST)], neurotoxicity [acetylcholinesterase (AChE)] and oxidative stress [superoxide dismutase (SOD), catalase (CAT) and lipoperoxidation (LPO)] were evaluated in B. extremus. The concentration of OP pesticide residues was higher in SS than in MS. Activity of AChE in B. extremus exposed to SS soil for 14 d was significantly more inhibited (78%) than in MS soil (68%). B. extremus has been shown to be a good bioindicator of contaminated soils in tropical regions.

Formula model established through field application of glass slides and rapid analysis of pesticide residues in vegetables by ion mobility spectrometry

The prevalence of pesticide usage has brought the matter of pesticide residues to the forefront, necessitating the development of effective detection methods as a crucial step towards addressing this issue. This study presents a novel approach for detecting pesticide residues in vegetables using glass slide-formula-ion mobility spectrometry (IMS). The approach enables swift analysis of 36 different pesticides across three vegetable species with glass slides. To establish a formula for calculating pesticide residues in vegetables using glass slides, the vegetable samples and glass slides were placed in a spray tower and evenly sprayed pesticides. The per unit area of glass slides was used to calculate the pesticide loading capacity and total pesticide loading area of vegetables. The original residues were analyzed with ultra high-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS). The field experiment yielded consistent results between the model values of the formula and the actual measured values, with correlation coefficients (R2) ranging from 0.927 to 0.983. The slide-formula model-IMS method was found to be effective for field applications, as it proved to be simple, rapid, and accurate in predicting pesticide residue concentrations in vegetable samples. This approach could be a valuable tool for monitoring pesticide residues in vegetable cultivation globally.

Comparative analyses of pesticide residues, elemental composition and mycotoxin levels in Spanish traditional and novel ciders

The apple cultivar, known for its adaptability and diverse varieties, has been extensively utilized for cider production, particularly in climatically suitable regions. Cider, an age-old alcoholic beverage derived from fermenting apple juice, is gaining popularity, especially among younger generations. Despite this trend, comprehensive knowledge regarding the toxicological profile of ciders remains limited, leaving room for potential chemical contaminants from raw ingredients or production methods. To address this gap, we conducted an unprecedented study analyzing sixty-eight cider samples from the Spanish market, encompassing both traditional ciders and newly developed apple-based flavored drinks referred to as “ciders.” Our investigation focused on pesticide residues, elemental profiles, and mycotoxin residues. In a groundbreaking approach, our study integrated the analysis of 225 pesticide residues, 50 Persistent Organic Pollutants (POPs), 11 mycotoxins (AFB1, AFB2, AFG1, AFG2, DON, FB1, FB2, H-2, HT-2, OTA, PAT, and ZEN), and a total of 50 elements. Pesticide residues were identified using GCMSMS and LCMSMS, elemental composition determined via ICPMS, and mycotoxins analyzed using LCMSMS. The significance of our research lies in addressing the dearth of toxicological analyses of ciders, despite their burgeoning global consumption and production. For pesticide residues and elemental composition, our results underwent statistical processing, revealing distinct differences between the elemental profiles of traditional ciders and “ciders.” Additionally, disparities were observed between cider and other low-alcohol fermented beverages like wines and beers. Concentrations of most pesticide residues and elements in the cider samples were deemed non-toxic, falling below allowable limits established by international organizations for other beverages such as water or wine. However, certain elements, notably Br and Pb in traditional ciders, raised potential concerns. Our findings underscore the necessity of establishing regulatory limits for pesticide residues, potentially hazardous elements, and mycotoxins in cider, a regulatory framework currently lacking on a global scale.

Polyaniline-coated kapok fibers for convenient in-syringe solid-phase microextraction and determination of organochlorine and pyrethroid pesticide residues in aqueous samples

Pesticides used in agriculture have low polarity and a tendency to accumulate in fatty tissues, posing potential risks to human health. Effective pre-treatment is crucial due to complex sample matrices and low concentrations of pesticide residues typically encountered in instrument analysis. In this study, polyaniline-coated kapok fiber (PANI-KF) was synthesized successfully using in-situ oxidative polymerization for use as sorbents in in-syringe SPME of pyrethroid pesticides (PYRs) and organochlorine pesticides (OCPs) from aqueous samples. Coating the natural KF with PANI maintained the hollow microtubular structure and fiber morphology while significantly enhancing the extraction efficiency. The extraction process was easily conducted by simply pulling and pushing the syringe plunger. The entire extraction process, utilizing 3 mg of PANI-KF, could be completed in approximately 3 min. Density functional theory results indicated that the adsorption mechanism of PANI-KF towards OCPs and PYRs mainly involved van der Waals interactions, π-π interactions, and weak hydrogen bonding interactions. With the coupling of gas chromatography-mass spectrometry, a quantification method was established that exhibited good linearities (R2 > 0.990), and relative recoveries (87.2–108.5 %). The limits of detection ranged from 0.4 to 2.0 ng mL−1 and the matrix effects were negligible (−12.3–16.4 %). The validated in-syringe SPME-GC-MS method was successfully applied to determine pesticide residues in fruit juices, oral liquids and herbal extract granules with satisfactory accuracy and precision. PANI-KF exhibits remarkable promise as a sorbent for the extraction and enrichment of pesticide residues in aqueous samples, thereby contributing to the advancement of pesticide residue determination methodologies.

Pesticide Residues and Associated Public Health Risks in Vegetables from Irrigated Farms Adjacent to Rift Valley Lake Ziway, Ethiopia

The overuse of pesticides has resulted in the accumulation of harmful residues in vegetables, which requires monitoring to assess the risks to human health. This article presents the levels of 35 pesticide residues in 15 composite vegetable samples from irrigated farmlands adjacent to Lake Ziway, Ethiopia, using the QuEChERS extraction method (Quick, Easy, Cheap, Effective, Rugged, and Safe) and then analyzes them using GC-MS. The study also estimated the health risks associated with the consumption of contaminated vegetables in children and adults, including carcinogenic and noncarcinogenic risks. The predominant pesticide residues found in tomatoes were α-endosulfan (0.58 mg/kg), β-BHC (0.04 mg/kg), heptachlor (0.02 mg/kg), and malathion (0.03 mg/kg), all of which were above the safety limits. Similarly, the mean concentration of heptachlor epoxide (0.04 mg/kg) and propargite (0.11 mg/kg) was higher than the allowed levels of the safety limits for onions. The concentration of pesticide residues detected in 10.6% and 7.9% of tomato and onion samples was above the maximum residual limits of the European Commission (EU-MRLs), respectively. Noncarcinogenic health risk estimates show that onion heptachlor epoxide had THQ > 1, indicating the possibility of systemic health risk in both adult and child consumers. The carcinogenic health risk (CHR) showed that heptachlor epoxide in adults and children and only heptachlor in children had CHR > acceptable limit (10−4) for tomato and onion. Therefore, it is critical to raise awareness among stakeholders while simultaneously implementing sound monitoring policy actions to protect the ecosystem and the health of the population in the study area and beyond.

One step cleanup of 160 pesticides and veterinary drugs in aquatic products using melamine-based automatic pressure filtration purification method combined with HPLC-MS/MS

A 15-channel pressure filtration purification method was presented for high throughput sample preparation of aquatic products. A cost-effective device was constructed and melamine sponge was selected as the cleanup sorbent. Upon interfacing with HPLC-MS/MS, the analytical procedure demonstrated its suitability for quantifying 160 pesticides and veterinary drug residues in aquatic products such as fish, shrimp, and crab. The method achieved sample recoveries ranging from 61.3 to 124.9 %. The detection limits were established between 0.5 and 1.0 μg/kg, while the quantitation limits were confirmed to be within the range of 1.0–2.0 μg/kg. The method was applied to quantify the pesticide and veterinary drug residues in mostly consumed aquatic products from five coastal provinces in China. The results showed significant differences between different aquatic products in the concentrations of pesticide and veterinary drug residues, implying the necessity of supervision for the accurate determination of pesticides and veterinary drugs.

Kinetics of the dissipation of azoxystrobin, quizalofop-p-ethyl, fluazifop-p-butyl and clomazone in fermented legume seeds

In this study, four plant matrices, including soybean, chickpea, pea, and lens, underwent fermentation by Bacillus subtilis var. natto. Then, the process influence on the content of four pesticides (clomazone, azoxystrobin, fluazifop-p-butyl, and quizalofop-p-ethyl) was evaluated, depending on the fermentation length. Fermentation was conducted for 312 h in controlled conditions of temperature and relative humidity (37 °C, 75%). The pesticide residue content in fermented seeds was assessed with the QuEChERS multiresidue method, combined with gas chromatography coupled with tandem mass spectrometry (GC-MS/MS). The studies demonstrated that Bacillus subtilis can biodegrade pesticides in legume seeds, with those microorganisms having a greater potential to degrade herbicides, especially fluazifop-p-butyl, and quizalofop-p-ethyl, than azoxystrobin and clomazone. The highest pesticide degradation occurred during first hours of fermentation. The quizalofop-p-ethyl and fluazifop-p-butyl levels reached < 0.02 mg/kg in nearly all studied seeds already after 48 h. At the end of fermentation (after 312 h), the azoxystrobin and clomazone levels ranged from 0.0203 mg/kg (soybean) to 0.0475 mg/kg (lens) and from 0.001 mg/kg (chickpeas) to 0.0753 mg/kg (lens), respectively. In all studied plant matrices, levels of pesticide residues were below the established MRLs, with clomazone being the sole exception.
