“…Carbaryl is an effective, long-residual, and broad-spectrum carbamate insecticide . Deng et al developed a polychromatic colorimetric sensor based on zinc (4-pyridinyl)porphyrin–dodecyl trimethylammonium bromide (ZnTPyP-DTAB) peroxidase activity and gold nanodouble-pyramid etching to detect carbaryls . The coordination interaction between zinc and nitrogen in the porphyrins was affected by the steric effects of the carbaryl group, which decreased the catalytic activity of ZnTPyP-DTAB.…”

A colorimetric sensor detects an analyte by utilizing the optical properties of the sensor unit, such as absorption or reflection, to generate a structural color that serves as the output signal to detect an analyte. Detecting the refractive index of an analyte by recording the color change of the sensor structure on its surface has several advantages, including simple operation, low cost, suitability for onsite analysis, and real-time detection. Colorimetric sensors have drawn much attention owing to their rapidity, simplicity, high sensitivity and selectivity. This Review discusses the use of colorimetric sensors in the food industry, including their applications for detecting food contaminants. The Review also provides insight into the scope of future research in this area.

“…Carbaryl residues, on the other hand, pose a significant environmental risk to humans, as well as causing damage to the body itself. Carbaryl is toxic to humans in many ways, damaging DNA and triggering chromosomal aberrations, leading to reproductive abnormalities in human sperm 4 . The main hazard of fenitrothion is the induction of lipid peroxidation and oxidative damage to polyunsaturated fatty acids, proteins and nucleic acids, which affects the function of various organs in animals and humans 5 .…”

Rice serves as a fundamental food staple for humans. Its production process, however, unavoidably exposes it to pesticides which may detrimentally impact its quality due to residues. Therefore, it is extremely necessary to monitor pesticide residues on rice during storage. In this research, the Quatformer model, which considers the effects of temperature and humidity on pesticide residues in rice grains, was utilized to forecast the amount of pesticide residues in rice grains during the storage process, and the predicted results were combined with actual observations to form a quality assessment index. By applying the K-Means algorithm, the quality of rice grains was graded and assessed. The findings indicated that the model had high prediction accuracy, and the MAE, MSE, MAPE, RMSE and SMAPE indexes were calculated to be 0.0112, 0.0814, 0.1057, 0.1055 and 0.0204, respectively. These findings provide valuable technical and theoretical support for planning storage conditions, enhancing pesticide residue decomposition, and monitoring rice quality during storage.
