Micr monitor of certaine pesticide residues in green beans and pomegranate in minia governorate (egypt)‎

Abstract EN

The present study was carried out to investigate a simple monitoring Program.

Monitoring study of pesticide residues was carried out in Minia Governorate (Egypt) during October 2018.

Forty- two samples of green beans and pomegranates collected from 6 local markets in El-Minya Governorate (i.

e.

Bani Mazar- Matai –Samalout-Minia-Abu Qurqas-Malawi).

Samples were extracted using (QuEChERS) method and analyzed using (LC-MS/MS) and (GC-MS/MS).

Results showed that 21.43% of the samples had no detectable pesticide residues.

However, 59.57% contained detectable residues without violation and 19% contained residues that exceeded the maximum residues limits (MRL's).

Green Beans samples recorded the highest contamination percentages without exceeding of the levels of MRL's (i.

e.72.22% ), followed by pomegranate (i.

e.50% ).

Data showed that pomegranates recorded the highest violation (i.

e.33.33% ), while green bean samples free of violation pesticide residues.

The highest frequently detected pesticide in all samples were Cypermethrin(13) followed by Imidacloprid(13) carbendazim(11), acetamiprid(8), Cyfluthrin(7), Thiophanate-methyl(7), lambada-cyhalthrin(5), Spirodiclofen(4), chlorpropham(3), Chlorpyrifos(3), Fenpyroximate(2) and Methomyl(2), and the synergist pipernyl butoxide which detected three times.

While the lowest frequently detected pesticides, which detected only one time in these samples were Carbofuran, carbofuran3-hydroxy, Diazinon, Dimethoate, Lufenuron, Methoxyfenozide, Omethoate, Profenofos and Tetramethrin.

The violation pesticides in pomegranate were seven i.

e.

Acetamiprid, Cyfluthrin, Chlorpyrifos, Dimethoate, Omethoate, Methomyl and Thiophanate- methyl.

The most contaminated green beans samples and pomegranate were found in Minia and Matay market followed by Abu Qarqas then Bani Mazar followed by Malawi and Samalut and farm in Malawi.

The results also showed that fifteen samples contained residues of one pesticide and two samples contained residues of eight pesticides
