بررسی مقدار باقی‌مانده سم دیازینون در پرتقال تامپسون

Background and purpose: Nowadays, the accumulation of toxins in food, water, land and air, is one of the most important arguments regarding human health and environment. The important feature is the chronic toxicity of pesticides they can accumulate in the body. The accumulation of toxins in the body occurs directly through exposure due to contact or indirectly through food, inhalation or absorption through the skin. The aim of this research was to evaluate the amount of residue “Diazinon” in orange products of citrus gardens in Sari. Material & methods: The extraction of this toxin was done using the organic solvent “n- hexane” from the samples of orange from the different regions in Sari. In this study, the evaluation the Diazinon amount was taken cared of by using gas chromatography which was equipped with mass spectrometry detector (MS). In this research, the sensitivity is set to ppb to determine the amount of toxin. All the results were statistically analyzed using one way-ANOVA and student t-test. Then Tukey-posttest was applied to compare the pesticides residue levels found in the samples (P< 0.05). Results: All results obtained from the different areas were in the normal range. Normal range for Diazinon residues in citrus fruits, according to the WHO is 0.7 Ppm. Conclusion: According to the results of this study, Diazinon was found in all samples. All values are normalized based on global standards.
