“…Due to their high resolution, precise mass accuracy, outstanding full-scan sensitivity, and complete mass spectrometry information, high-resolution mass spectrometry (HRMS), such as time-of-flight mass spectrometry (TOF/MS) and quadrupole Orbitrap mass spectrometry (Obitrap/MS), can be used without additional sample injection. Under retrospective analysis, with these advantages, HRMS has been widely used in the field of food analysis [22,23]. Lehotay et al used GC-TOF to analyze 34 pesticides in flaxseed, dough, and peanuts [15].…”

Cottonseed hull is a livestock feed with large daily consumption. If pesticide residues exceed the standard, it is easy for them to be introduced into the human body through the food chain, with potential harm to consumer health. A method for multi-residue analysis of 237 pesticides and their metabolites in cottonseed hull was developed by gas-chromatography and liquid-chromatography time-of-flight mass spectrometry (GC-QTOF/MS and LC-QTOF/MS). After being hydrated, a sample was extracted with 1% acetic acid in acetonitrile, then purified in a clean-up tube containing 400 mg MgSO4, 100 mg PSA, and 100 mg C18. The results showed that this method has a significant effect in removing co-extracts from the oily matrix. The screening detection limit (SDL) was in the range of 0.2–20 μg/kg, and the limit of quantification (LOQ) was in the range of 0.2–20 μg/kg. The recovery was verified at the spiked levels of 1-, 2-, and 10-times LOQ (n = 6), and the 237 pesticides were successfully verified. The percentages of pesticides with recovery in the range of 70–120% were 91.6%, 92.8%, and 94.5%, respectively, and the relative standard deviations (RSDs) of all pesticides were less than 20%. This method was successfully applied to the detection of real samples. Finally, this study effectively reduced the matrix effect of cottonseed hull, which provided necessary data support for the analysis of pesticide residues in oil crops.

“…Simple indicators of pesticide hazard use even with rare data, which are easy to calculate and to communicate, are suitable [10]. Although there are several uncertainties in the capacity of these indicators to estimate the risk of pesticide use, they provide valuable information [34] when compared to costly environmental media sampling and monitoring for pesticides [35,36]. Accordingly, the use of these tools offers farmers a chance to minimize the environmental impact and human exposure to pesticide residues [37,38].…”

Different pesticides are widely used to protect the crops. However, they are considered to be one of the major causes of environmental pollution. Therefore, in this project, efforts are made to characterize the potential risks of pesticides applied, to study their effects on the environment, and to understand the local professional practices. A survey was conducted among market gardeners and farmers, in two main districts of Biskra Ziban, Algeria. Using pesticide environmental risk indicator model, an Environmental Risk Score (ERS), the final indicator of environmental risk (final indicator of ER), and the normalized final environmental risk were calculated for 18 pesticides, which are most commonly used. Six active ingredients had an ERS that reached a value of 5 and more. The highest final indicator of ER was obtained for the formulation based on the active substance diazinon (score = 120.00). Besides, the perception and attitude of farmers regarding risk from pesticide exposure were also observed and discussed. Consequently, the risk indicators allowed us to compare and identify the least environmentally hazardous pesticide among all the possible alternatives.During cultivation, vegetables and fruits require the use of a broad range of pesticides. Pesticides, when released into the environment, can follow many pathways [6]. Pesticides have a tendency to be sorbed to soil particles [7]; pesticides with high vapor pressures may be easily lost to the atmosphere or move downward into aquifers, whereas soluble pesticides are more leachable to soil and groundwater. Nevertheless, it may be lost as surface water runoff because of irrigation practices or rainfall [7,8]. Pesticides may be degraded and transformed by the biological and chemical processes such as photolysis, hydrolysis, oxidation, and reduction [7,[9][10][11][12].Pesticides benefit the crops, but they negatively impact the environment, particularly, when they move outside of the application site [13,[14][15][16]. Biodiversity is mainly threatened by the intensive use of pesticides [17]. Besides, insecticides or herbicides can be toxic to the hosts of other organisms, birds, aquatic life, beneficial insects, and non-target plants [18,[19][20][21]. Furthermore, pesticides can contaminate soil, water, turf, and

“…This diversity causes serious problems in the development of a -universal‖ analytical method having a widest possible scope. Gas chromatography (GC) and liquid chromatography (LC) have been utilized for the development of specific and sensitive methods for the determination of pesticides (Alder et al, 2006, Elbashir andAboul-Enein, 2017). Pesticides and other chemicals have been traditionally quantified using triple quadrupole mass spectrometers (LCMS-QQQ, Botero-Coy et al, 2011).…”

We have developed a novel yet efficient method for the multi residue analysis of organic compounds of diverse polarities in water using Liquid Chromatography-Time of Flight mass spectrometry (LC-MS-TOF) equipped with a jet stream Electrospray ionization (ESI) source. Use of three different fragmentor voltages (low, medium and high) enabled the qualitative and quantitative analysis of a diverse range of targeted organic compounds in environmental waters. No prior optimization of compounds being quantified was required, the limiting factors were ionization behaviour of compounds under conditions of ESI and good chromatography. Same data file could be subjected to repeated post-run data analysis to figure out the presence of non-targeted compounds, including designer drugs if any. The technique has been illustrated with reference to a group of pesticides having diverse chromatographic and ionization behaviours. The optimized Solid Phase Extraction (SPE) followed by method validation yielded a robust yet simple quantitative method for a group of fourteen pesticides. We were able to achieve quantitation at 10 ng/L or lower depending upon ionization behaviour of substrates against the usual regulatory requirement of 1000 ng/L. The method was used for targeted and non-targeted detection of pesticides in Nueces estuary waters, TX, USA, and several untargeted pesticides, pharmaceuticals and personal care products were identified.
