The aim of this study is to assess the pesticides residues in wheat and soil samples from Ghaziabadcity of India. Herein, wheat and soil samples were collected from fields in Ghaziabad city, India from2017 to 2019 and analyzed on GC-MS/MS & LC-MS/MS using QuEChERS method of extraction.One or multiple pesticide residues were detected in the wheat and soil samples. Cypermethrin,cyahalofep butyl and chlorpyrifos were frequently detected in the soil samples. Concentrations ofcarbendazim and chlorpyrifos in the paired soil and wheat samples exhibited significant positivecorrelations. The monitoring results showed that the concentrations of some pesticides in the wheatflour samples exceeded the FSSAI MRL standard, which implies possible intake risks via consumption.Hence, dietary risk assessments were conducted. The resulting hazard quotient (HQ) values fell within3.89-7.25 indicates that dietary risk of studied crop is low and their current residue concentrations inwheat would be safe for human consumption.
