“…All components present in related matrices as oils, hemp, or foods can negatively affect the extraction of the contaminants, provoking significant matrix effects. [30][31][32] QuEChERS (acronym of quick, easy, cheap, effective, rugged and safe) and solid-liquid extraction (SLE) were the common extraction methods developed for extracting harmful residues and contaminants (pesticides, mycotoxins, etc.) from cannabis products (Table 2).…”

In the last few years, the cultivation of cannabis has been increasing due to greater use in foods, recreational use, creams, oils, and other applications. Thus, analysis of contaminants (e.g. pesticides and mycotoxins) in cannabis products is necessary to ensure consumer safety. This review is focused on the analytical procedures, based on chromatographic techniques, used for the determination of contaminants in cannabis and related products, developed from 2015 to 2020. QuEChERS (acronym of quick, easy, cheap, effective, rugged and safe) was mainly used for the extraction of pesticides and other contaminants from cannabis because its versatility and capacity to extract a wide range of substances, and therefore, increasing the scope of the analysis. The most employed technique to determine pesticides and mycotoxins in cannabis products was liquid chromatography (LC) coupled to mass spectrometry (MS), although gas chromatography (GC) coupled to MS was also employed for the analysis of non-polar compounds, using triple quadrupole (QqQ) as mass analyzer. Nevertheless, new advances in cannabis analysis are also discussed, introducing techniques such as high-resolution mass spectrometry (HRMS), which allows for performing both targeted and untargeted (unknown and suspect) analyses.

“…2 to 15) differ slightly in terms of sensitivity and linear range from published results [7,[23][24][25] and may indicate sample matrix interference that should be further studied in future works. Suggestions on sample matrix removal include the use of dispersive solid-phase extraction using a microporous metal-organic framework [26] and fabric phase sorptive extraction in conjunction with gas chromatography and mass spectrometry [27].…”

Most of the locally consumed beans in our vicinity contain excess chemicals of pesticides residues which are harmful to humans and environmental hazards to ecosystem. Investigation of this study revealed contamination level of organochlorine pesticides residues in dried beans originating from Nigeria with a view to controlling them, it also studies crude fiber of beans showed that B4 has the highest fiber content, 27.85% and the order of decreasing value as B4, B5 , B1, B3 and B2. The least percentage of crude fiber was shown by B2 in all the beans samples analyzed. This study also investigated the pesticides residue components of the organochlorinated pesticides test. The presence of pesticide residues in all 14 types of organochlorine pesticides in beans is lower than a previously reported level. Despite this, the amount of organochlorine pesticides tested is more than the permitted levels of 0.01 to 0.2 mg/kg, indicating that the beans consumed in the Gombe metropolis included pesticide residues beyond the permissible limit.

“…Therefore, it is crucial to achieve rapid detection and reliable quantification of carbaryl. Traditional detection methods, such as chromatography [ 9 , 10 , 11 , 12 ], surface-enhanced Raman spectroscopy [ 13 , 14 , 15 ], immunoassay [ 16 , 17 ], etc., have been developed very well, with high sensitivity and accuracy in the determination of pesticide residues in water and agricultural products. However, the limitations lie in the complex sample handling process, the use of highly toxic organic solvents and the expensive and complex instruments that require professional testing [ 18 , 19 , 20 ].…”

A ratiometric electrochemical biosensor based on a covalent organic framework (COFThi-TFPB) loaded with acetylcholinesterase (AChE) was developed. First, an electroactive COFThi-TFPB with a two-dimensional sheet structure, positive charge and a pair of inert redox peaks was synthesized via a dehydration condensation reaction between positively charged thionine (Thi) and 1,3,5-triformylphenylbenzene (TFPB). The immobilization of AChE on the positively charged electrode surface was beneficial for maintaining its bioactivity and achieving the best catalytic effect; therefore, the positively charged COFThi-TFPB was an appropriate support material for AChE. Furthermore, the COFThi-TFPB provided a stable internal reference signal for the constructed AChE inhibition-based electrochemical biosensor to eliminate various effects which were unrelated to the detection of carbaryl. The sensor had a linear range of 2.2–60 μM with a detection limit of 0.22 μM, and exhibited satisfactory reproducibility, stability and anti-interference ability for the detection of carbaryl. This work offers a possibility for the application of COF-based materials in the detection of low-level pesticide residues.
