ملخص المقالة :
در سال‌های اخیر وجود نیترات و نیتریت در سبزیها به یکی از نگرانی‌ها در سطح افکار عمومی تبدیل شده است. هدف این تحقیق بررسی وضعیت تجمع نیترات و نیتریت در سبزی‌های عرضه شده در بازار شهرکرد بود. برای این منظور در زمستان 1390 و تابستان 1391 تعداد 222 نمونه جمع‌آوری و تجمع نیترات و نیتریت در آن‌ها اندازه گیری شد. نتایج نشان داد که میانگین تجمع نیترات در سبزی‌های مختلف دارای طیف گسترده ای از 9/310 میلی گرم بر کیلوگرم وزن تر در نعناع تا 1/3309 میلی گرم بر کیلوگرم وزن تر در مرزه بود. در بیش از 85 درصد از نمونه‌ها میانگین تجمع نیترات کمتر از حد استاندارد (2500 میلی گرم بر کیلوگرم وزن تر) بود، در حالی‌که در مرزه بیش از 3000 میلی گرم بر کیلوگرم وزن تر برآورد شد. هم‌چنین مشخص گردید که میانگین تجمع نیتریت در مقایسه با نیترات بسیار پایین و 65/1 میلی گرم بر کیلوگرم وزن تر بود. یافته‌ها نشان داد که تجمع نیترات در فصل تابستان به‌طور معنی داری (05/0p<) بیشتر بود اما در مورد نیتریت عکس این حالت مشاهده شد. بر اساس نتایج این پژوهش، میزان تجمع نیترات و نیتریت در سبزی‌های عرضه شده در شهرکرد تهدیدی برای سلامت مصرف‌کنندگان محسوب نمی‌شود، با این حال به‌کارگیری روش‌های موثر برای کاهش تجمع نیترات و نیتریت در سبزیها توصیه می‌گردد.
