“…We, therefore, developed a clean-up step using common chromatographic sorbents prior to LC injection. We examined the highly-polar neutral alumina that possesses properties close to silica gels that are commonly used to remove aromatic and aliphatic compounds [ 29 , 30 ]. PSA (primary secondary amine) is a weak anion exchanger that can remove fatty acids, sugars and other components that can form hydrogen bonds [ 31 ].…”

We developed a method for determination of imidacloprid and its metabolites 5-hydroxy imidacloprid, olefin imidacloprid, imidacloprid urea and 6-chloronicotinic acid in Procambarus clarkii (crayfish) tissues using quick, easy, cheap, effective, rugged, and safe (QuEChERS) and high-performance liquid chromatography-triple quadrupole mass spectrometry. Samples (plasma, cephalothorax, hepatopancrea, gill, intestine, and muscle) were extracted with acetonitrile containing 0.1% acetic acid and cleaned up using a neutral alumina column containing a primary secondary amine. The prepared samples were separated using reverse phase chromatography and scanned in the positive and negative ion multiple reaction-monitoring modes. Under the optimum experimental conditions, spiked recoveries for these compounds in P. clarkii samples ranged from 80.6 to 112.7% with relative standard deviations of 4.2 to 12.6%. The limits of detection were 0.02–0.5 μg·L−1, the limits of quantification were 0.05–2.0 μg·L−1 and the method of quantification was 0.05–2.0 μg·kg−1. The method is rapid, simple, sensitive and suitable for rapid determination and analysis of imidacloprid and its metabolites in P. clarkii tissues.

“…LC-MS/MS can be employed to detect a broad variety of polar and moderately polar pesticides. While only GC-MS/MS can be used to determine highly non-polar pesticides (Maestroni et al, 2020). Therefore, in the current study, both LC-MS/MS and GC-MS/MS techniques were used to gure out the simultaneous residue determination of a large number of pesticides in ve herbal plants collected from uncontrolled traditional local markets in three Egyptian governorates (Cairo, Beni Suef, and Fayoum).…”

In developing countries, herbal plants are not only sold under controlled conditions (in markets and pharmacies), but also sold in traditional markets without proper control conditions. For this reason, a total of 120 samples of five different medicinal plants were collected from local markets in three different Egyptian governorates (40 samples for each governorate), and the presence of a wide range of pesticides residues was tested. The collected samples were extracted and cleaned up by an accredited analytical method, based on the known QuEChERS extraction approach and using GC-MS/MS and LC-MS/MS. Results revealed that 63 pesticide residues were found in samples collected from three different governorates. Notably, more than fifteen pesticides were detected in eight samples. Furthermore, chlorpyrifos was the most frequently detected pesticide. Additionally, thiophanate-methyl had the highest concentration with a concentration of 5.65 mg kg-1, followed by malathion with a concentration of 2.55 mg kg-1, both of which were detected in Cairo Governorate. In conclusion, these results not only indicate the presence of uncontrolled pesticide practices in herbal agriculture production but also suggest the existence of an uncontrolled import of highly contaminated herbs. Furthermore, a probability of pesticide treatments during their storage stage may be occurred in the uncontrolled local traditional market.

“…Hence, this increase requires that the analytical method is fast, ingenious, accurate, and convenient. In order to accelerate the process of internationalizing and modernizing traditional Chinese herbal medicine, analysis methods, including GC,LC,GC/MS,LC/MS,SFC,CE,CE/MS and ELISAs for the detection of pesticide residues have been used to determine pesticide residues [23][24][25][26] . Great progress has been made on new analytical methods and techniques at present, especially in pesticides multiresidue analyses method.…”

A fast and sensitive multi-residue analytical method was developed for the determination of organophosphorus pesticide residues in Panax notoginseng and Aucklandia lappa decne by comparing an ultrasonic extraction and homogenate extraction approach coupled with automated solid-phase extraction system and gas chromatography-mass spectrometry (GC/MS). Various factors affecting the homogenate extraction and purification efficiency were investigated in detail. The optimum conditions for homogenate extraction of organophosphorus pesticide residues from Panax notoginseng and Aucklandia lappa decne were 60 mL dichloromethane, 10000 r/min of extracting revolution speed and 2 min of extracting time. The extracts were cleaned up by automated solid-phase extraction system and determined by GC/MS. Under the optimum conditions, the results of the homogenate extraction approach were compared with those of the ultrasonic extraction, and the homogenate extraction approach was used to extract the samples. The average recoveries of the method by a homogenate extraction approach coupled with automated solid-phase extraction system and GC/MS ranged from 72.56% to 96.70%, and RSDs were 0.05~0.14%, which allowed the determination of 16 organophosphorus pesticide residues in Panax notoginseng and Aucklandia lappa decne. The results indicated that the proposed method can apply for the determination of organophosphate pesticides residues in Panax notoginseng and Aucklandia lappa decne with high accuracy and precision.
