چکیده

گوشت و بعضی از اندامهای بز و گوسفند به علت خوش مزاجی و طعم و مزه خوب، یکی از مهمترین و پرمصرف­ترین منابع تغذیه­ایی انسان می­باشند. بنابراین پایش سطوح غلظت فلزات در بافت­های حیوانات برای ارزیابی اثر آلودگی روی سلامت حیوان و ایمنی تولیدات با منشا حیوانی مهم هستند. این مطالعه به منظور تعیین سطوح فلزات مس، روی و کروم در بافت­های ماهیچه، کبد و کلیه گوسفندان و بزهای کشتار شده در شهرستان بیرجند با توجه به جنبه­های بهداشتی و سم­شناسی انجام گردید. مقادیر عناصر موجود در بافت­های مختلف بز و گوسفند با استفاده از دستگاه اسپکتروفتومتر جذب اتمی شعله تعیین گردید. آنالیز آماری داده­ها با استفاده از نرم افزار SPSS انجام و اختلاف معنی­دار در سطح 05/0 محاسبه شد. نتایج این مطالعه نشان داد که کبد و کلیه­ها دارای بیشترین و ماهیچه ها دارای کمترین مقدار فلزات فوق بودند. همچنین از نظر سطوح فلزات بین بافت­های یکسان بزها و گوسفندان اختلاف آماری معنی­دار (05/0p<) مشاهده شد. با توجه به نتایج، تمام مقادیر مس و روی در نمونه های مورد مطالعه پایین تر و مقدار کروم بیشتر از حد مجاز تعیین شده توسط  ANZFAبودند.

چکیده [English]

Owing to its wholesomeness and good taste, meat of goats and sheep is the most important human food resource. So, monitoring levels of mineral concentrations in animal tissues is important for assessing the effect of contamination on animal health and safety of animal origin products in human nutrition. This study was performed to monitor the metals levels of copper, zinc and chromium in liver, kidney and muscle of goats and sheep slaughtered in the city of Birjand with attention given to hygienic and toxicological aspects. The elements content in different tissues of goats and sheep were determined using flame atomic absorption spectrophotometer. Statistical analysis of data were performed with SPSS software and significance difference were considered with P value below 0.05.The results of this study showed that the liver and kidney had the highest levels of metals while the muscles were in the lowest levels metals. Also, a difference was observed between same tissues of goats and sheep in terms of the amount of metals. With attention to results all the copper and zinc values in the all samples were below and chromium content in the all samples was higher than the permissible limit set by ANZFA.
