The objective of this study was to know the residuality and concentration of thiamethoxam in the papaya agroecosystem, in the main papaya fruit producing zone in the central area of the Gulf of Mexico. It was carried out during a papaya growing cycle with watermelon rotation; the taking of samples was according to the technique established by the NOM -AA-103-1988 for leaves and for fruit the NMX -FF-041-1996 by the method of quartering in papaya and watermelon, the samples were analyzed with a HPLC-UV, the data obtained were statistically analyzed by parametric and non-parametric Kruskal-Wallis tests. The presence of thiamethoxam was found in papaya and watermelon cultivation plants, the concentrations in papaya leaves reported a maximum value of 0.29 mg/kg, while for the leaves of the watermelon rotation fruit it was 0.15 mg/kg. In papaya fruit, thiamethoxam concentrations are within a range of 0.24 to 0.32 mg/kg. The concentrations and residuality of thiamethoxam mainly exceed the maximum tolerance and residuality limits of the EFSA and FAO. 2024 artículo científico 1390-6542 https://www.redalyc.org/articulo.oa?id=572278419010 https://www.redalyc.org/journal/5722/572278419010/ https://www.redalyc.org/journal/5722/572278419010/html/ https://www.redalyc.org/journal/5722/572278419010/572278419010.epub https://www.redalyc.org/journal/5722/572278419010/movil https://doi.org/10.29019/enfoqueute.1037 en http://www.redalyc.org/revista.oa?id=5722 Enfoque UTE application/pdf Universidad UTE Enfoque UTE (Ecuador) Num.3 Vol.15 |
