Special Issue Information

Dear Colleagues,

Pesticide residues in food and environmental samples pose significant risks to public health and ecological systems. These residues, including parent compounds, isomers, enantiomers, and metabolites, frequently occur in diverse matrices, posing challenges for accurate detection and regulatory compliance. This Special Issue aims to showcase innovative research and advancements in pesticide residue analysis, emphasizing methodologies that enhance food safety and environmental protection.

We welcome contributions focusing on the development and application of reliable, sustainable, sensitive, and regulatory-compliant analytical methods. Topics of interest include, but are not limited to, liquid-phase and solid-phase microextraction, QuEChERS, chromatographic techniques, mass spectrometry, ultraviolet and fluorescence detection, colorimetric assays, electrochemical analysis, enzyme-linked immunosorbent assays, and sensor-based technologies. Studies investigating innovative or integrated approaches for detecting pesticide residues in complex matrices are particularly encouraged.

This Special Issue covers a wide array of sample types, including fruits, vegetables, grains, juices, wines, water, soil, and atmospheric samples, spanning both food and environmental systems.

We invite original research articles and reviews that contribute to accurate and reliable solutions for the analysis of pesticide residues.

The global application of neonicotinoids (NEOs) has precipitated pervasive contamination of agricultural matrices, with China’s staple crop lands representing critical exposure hotspots. The occurrence and ecological risks of ten NEOs in the field soils of three major crops (i.e., rice, wheat and corn) in China were investigated in the present study. Employing an optimized UPLC-MS/MS method (LOQ = 0.01–1.7 ng/g, RSD < 12.21%), ten NEOs across 69 representative field soils (rice: 23, corn: 18, wheat: 28) were quantified. It was found that the detection frequency (DF) of the NEOs was 100% in the soil. The DFs of NEOs in the soil followed the rule: imidacloprid (IMI, 100%) > thiamethoxam (TMX, 88.4%) > clothianidin (CLO, 87.0%) > acetamiprid (ACE, 46.4%) > dinotefuran (DIN, 7.2%) > nitenpyram (NIT, 1.4%). Mean total detected NEOs concentrations exhibited crop-dependent type: wheat (1.77–214.55 ng/g) > corn (0.79–97.53 ng/g) > rice (0.75–72.97 ng/g). The IMI, CLO and TMX triad constituted over 90% of the total contribution of detected NEOs. In addition, CLO and TMX in the rice soils, IMI, CLO and TMX in the corn soils and IMI, CLO and TMX in the wheat soils had medium ecological risks. Therefore, it is particularly important for agricultural ecological protection to strengthen monitoring and take effective measures to protect agricultural ecology. Full article
