Abstract
The final effect of pesticides and their mixtures on living organisms is determined by the particular toxicodynamics of the system. Oxidative stress is one of the most studied molecular mechanisms of toxicity due to increasing evidence supporting its association with the toxic effects of different agrochemicals. In the present study we evaluated the presence of redox balance alterations in the cell lines HEp-2 and A549 exposed to formulations of glyphosate (March®) and cypermethrin (Superfina®) used separately or in combination (in a proportion equivalent to that used in soybean fields). We determined the activity of catalase, superoxide dismutase, glutathione S-transferase, intracellular GSH content, content of oxidized proteins (as measure of damage) and intracellular ROS content in both cell lines at two different mixture concentrations. Additionally, we evaluated the presence of statistical interaction to determine if the effect of the mixture on the parameters evaluated was additive, synergistic, or antagonistic. For this purpose, we used the Combination Subthresholding, Cooperative Effect and Statistical Linear Interaction approaches. We found that the interaction between pesticides depended on their concentration and the cellular models studied.

Abstract
Iprodione is a dicarboximide fungicide that is widely used in agriculture around the world. A reliable and rapid detection method is needed for the on-site monitoring of iprodione residues in a variety of agricultural products. Herein, a colloidal gold immunochromatographic test strip was developed based on a selected coating antigen and a specific monoclonal antibody against iprodione. The particle size of colloidal gold, the preparation technique of the conjugate pad, the composition of the loading buffer, and the extraction solvent were comprehensively optimized for the test strip. A cut-off value of 0.9 mg kg-1 (50 ng mL-1) and a visual limit of detection of 0.09 mg kg-1 (5 ng mL-1) were achieved in a complex matrix of tobacco. No cross-reactivity was observed for iprodione metabolite and four other widely used pesticides during tobacco growth. Furthermore, the developed colloidal gold immunochromatographic test strip was applied to determine iprodione residues in tobacco samples, and the obtained results were in good agreement with those obtained by liquid chromatography tandem mass spectrometry. Additionally, the test strip was found to be stable afterlong-term storage at 37 °C for two months. The developed colloidal gold immunochromatographic test strip showed excellent accuracy, sensitivity, specificity, and stability, therefore, it is suitable for the rapid detection of iprodione residues in complex matrices.

Abstract
Devices based on lateral flow assay (LFA) have been gaining more and more space in the detection market mainly due to their simplicity, speed, and low cost. These devices have excellent sensing format versatility and make these strips an ideal choice for field applications. The COVID-19 pandemic boosted the democratization of this method as a "point of care testing" (POCT), and the trend is that these devices become protagonists for the monitoring of pesticides in the environment. However, designing LFA devices for detecting and monitoring pesticides in the environment is still a challenge. This is because analytes are small molecules and have only one antigenic determinant, which makes it difficult to apply direct immunoassays. Furthermore, most LFA devices provide only qualitative or semi-quantitative results and have a limited number of applications in multi-residue analysis. Here, we present the state of the art on the use of LFA in the environmental monitoring of pesticides. Based on well-documented results, we review all available LFA formats and strategies for pesticide detection, which may have important implications for the future of monitoring pesticides in the environment. The main advances, challenges, and perspectives of these devices for a direction in this field of study are also presented.

Food Chem X 2021; 9:100117. [PMID: 33778481 PMCID: PMC7985707 DOI: 10.1016/j.fochx.2021.100117] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2020] [Revised: 02/16/2021] [Accepted: 02/18/2021] [Indexed: 12/02/2022] Open
Abstract
An ICA was developed for P. aeruginosa detection. The ICA strip showed a limit of detection of 2.41 × 104 CFU/mL. The ICA could be applied to detect P. aeruginosa in water and food samples.
Pseudomonas aeruginosa (P. aeruginosa) is the common infection-causing bacterial pathogen. Conventional methods for the detection of P. aeruginosa are time-consuming, and therefore, a more rapid analytical method is required. Here, monoclonal antibodies (Mabs) against P. aeruginosa (CICC 10419) were prepared and based on paired Mabs, an immunochromatographic assay (ICA) was developed. The ICA strip showed a limit of detection of 2.41 × 104 CFU/mL and the linear range of detection was 3.13 × 104-1.0 × 106 CFU/mL. No cross-reactivity was observed when other common Gram-negative and Gram-positive bacteria were used. The analytical performance of the ICA strip indicated that the developed ICA had good specificity and stability. Moreover, the feasibility of the ICA strip was verified by detecting P. aeruginosa (CICC 10419) in spiked water and food samples. The ICA strip could detect samples contaminated with a low-level of P. aeruginosa (CICC 10419) after 8 h enrichment.
