Residuos de plaguicidas en biomasa agrícola de chile (Capsicum annuum L.) usando un método QuEChERS acoplado a LC-MS/MS y GC-MS/MS

The intensive production of horticultural crops generates large amounts of agricultural biomass (BA), which is burned in the openfield or deposited in landfills becoming an environmental problem, especially if they are contaminated by pesticide residues. Thestudy aimed to evaluate the presence of pesticides in the BA of bell pepper, jalapeño pepper, and poblano pepper, using aQuEChERS method coupled to LC/MS-MS and GC/MS/MS. An analysis of the maximum residue limits was carried out,contrasting different regulations worldwide. Pesticide residues were quantified in the three BA, with jalapeño and poblano peppersbeing the most contaminated, highlighting lambda-cyhalothrin (1.11 mg/kg⁻¹), bifenthrin (1.62 mg/kg⁻¹), cypermethrin (0.34mg/kg⁻¹), imidacloprid (4.51 mg/kg⁻¹) and cyromazine (4.04 mg/kg⁻¹). Pesticide residues were identified in the BA, so its disposalis recommended to be regulated and monitored.
