The Dissipative Potential of Gamma Irradiation in Residues of Imidacloprid and Thiamethoxam in the Postharvest of Common Beans

Abstract: Pesticide residues remaining from bean cultivation, sensitive to optimal doses of gamma irradiation, can be transformed into other less harmful or nonharmful substances, increasing the quality of the beans before the food arrives at the consumer's table. Irradiation of the grains after harvest also eliminates the need for application of other pesticides to preserve the grains during storage, as the technique is capable of eradicating deteriorating agents, such as microorganisms and insects.

“…[6][7][8][9] The environmental behavior of IMI metabolites in soils, animals and plants has been researched extensively, but there has been no comprehensive study on the forced metabolic mechanism of IMI. Summarizing various research studies, the metabolic pathway of IMI can be summed up in four ways [10][11][12][13][14][15][16] (i) denitrification directly generates guanidine IMI, which is then further oxidized to carbonyl IMI (urea IMI); (ii) reducing nitro to nitroso derivatives, nitroso into guanidyl IMI; (iii) oxidizing imidazolidine rings, forming 5-OH IMI, 4-OH IMI or 4,5-dihydroxyl IMI (4,5-diOH IMI), then dehydration into olefin IMI; (iv) IMI forms different conjugates with coexisting small molecules (amino acids, maltose, glucose, succinic acid, etc.) ( Fig.…”

“…Por outro lado, apesar da irradiação de alimentos ter sido estudada por muitos cientistas, apenas alguns focaram no efeito da irradiação gama na remoção de resíduos de pesticidas de alimentos de origem vegetal, sendo a maioria dos estudos destinados à degradação dos pesticidas por radiação gama em água e embalagens (ARMELIM et al, 2018;CHOWDHURY et al, 2014;COSTA;TORNISIELO;WALDER, 2001;BASFAR;MOHAMED;AL-SAQER, 2012;MOHAMED et al, 2009;MORI et al, 2006).…”

“…Algumas pesquisas, demostraram que a dosagem de pesticidas na amostra pode influenciar na degradação; portanto, mais estudos são necessários para avaliar pesticidas em diferentes concentrações (LUCCHINI, 1955;MORI et al, 2006;KAUSHIK;SATYA;NAIK, 2009;MOHAMMED et al, 2009;BASFAR;MOHAMED;AL-SAQER, 2012;CHOWDHURY et al, 2014;ARMELIM et al, 2018). Além disso, devido à complexidade da matriz alimentar e às particularidades do grupo químico de cada pesticida, mais pesquisas são necessárias para compreender a interação entre a matriz alimentar, o grupo químico e a dosagem de radiação.…”
