en Investigation of Phosalone Residues in the Early and Late Varieties of Peach Products of Orchards Saman City, Chaharmahal and Bakhtiari Province in 2019 public specific orginal article <div style="text-align: justify;">Background: Nowadays, increasing the use of pesticides to manage the agriculture production resulted in increased pesticide residues in final products and concerns about environmental pollution and prevalence of emerging diseases. This study aims to investigate the residual amount of Phosalone toxin in the early and late varieties of peach orchards in Saman city located in Chaharmahal and Bakhtiari province. Methods: In this study, 60 samples of early and late peach varieties of peach orchards were selected randomly. Phosalone residues in early and late peach varieties before and after washing, and after peeling were extracted by QUECHERS method and the amount of extracted toxin were measured by high-performance liquid chromatography (HPLC). The data were analyzed using SPSS v.24 software. Results: Phosalone residues in early peach varieties before and after washing were 3.55 ± 0.94 and 0.31 ± 0.29 mg/kg, respectively. The concentration of Phosalone residues in unwashed early and late peach varieties before washing was 3.17 ± 0.97 mg/kg but decreased to 0.64 ±0.74 mg /kg after washing. Peeling reduced 97.79% of the Phosalone residues in late peach.   Early and late peaches covered by the plant pathology clinic and unwashed late peaches not covered by plant pathology clinic were significantly (P < 0.05) higher than the Iranian national standard (2 mg/kg). Conclusion: Washing and peeling the peach significantly decreased the toxin residues. In order to minimize the risk of exposure to Phosalone residues, integrated pest control management programs are essential.  </div> Toxin Residues, Phosalone, Peach 443 451 http://jnfs.ssu.ac.ir/browse.php?a_code=A-10-487-1&slc_lang=en&sid=1 Reza Faraji 0000-0002-6543-2803 No Department of Environmental Health Engineering, School of Health, Shahrekord University of Medical Sciences, Shahrekord, Iran Mehraban Sadeghi 0000-0002-0751-1254 No Department of Environmental Health Engineering, School of Health, Shahrekord University of Medical Sciences, Shahrekord, Iran Ramezan Sadeghi 0000-0002-3257-4215 Yes Department of Environmental Health Engineering, School of Health, Shahrekord University of Medical Sciences, Shahrekord, Iran Gashtasb Mardani 0000-0003-0312-4634 No Medical Plants Research Center, Shahrekord University of Medical Sciences, Sharhekord, Iran Morteza Sedehi 0000-0003-4403-1709 No Department of Epidemiology and Statistic, School of Health, Shahrekord University of Medical Sciences, Shahrekord, Iran Farshid Shabani Borujeni 0000-0003-3439-3829 No Organization of Agricultural Jahad, Plant Protection Management, Shahrekord, Iran
