چکیده

آلودگی محیط‎زیست با پسماند‌های خطرناک و زیان‌آور در بسیاری از موارد غیر قابل اصلاح است. آفت‌کش‌های تاریخ منقضی در انبارهای سراسر جهان یکی از این نوع پسماندها هستند. عدم توجه و رسیدگی به این انبارها پیامدهای ناگواری برای انسان‌ها و محیط‎زیست در پی دارد. این تحقیق با هدف بررسی امکان بازیافت سموم تاریخ منقضی موجود در انبارهای شرکت خدمات حمایتی کشاورزی انجام شده است. تست‌های کنترل کیفی نمونه‌ها براساس دستورالعمل‌های فائو،‌ اتحادیه بین المللی شورای تجزیه شیمیایی آفت‌کش‌ها و شرکت‌های سازنده آفت‌کش‌ها انجام شد. نتایج میزان تجزیه شدن این آفت‌کش‌ها بر اساس مدت زمان تولید آن‎ها، نوع فرمولاسیون، شاخص‌های کنترل کیفی و شرکت‌های تولید‎کننده فرمولاسیون EC دسته‎بندی شد. تجزیه و تحلیل آماری بر اساس آزمون کای دو  برای تعیین اختلاف بین متغیرهای مورد مطالعه و آزمون ریسک برای نشان‌ دادن ریسک نسبی تجزیه شدن انجام شد. نتایج نشان داد که در نمونه‌های مورد بررسی همبستگی معنی‌داری بین مدت زمان تولید آفت‌کش‎ها و درصد تجزیه شدن آن‎ها وجود ندارد. درصد تجزیه شدن در فرمولاسیون‌های EC، SC، WP و SL به ترتیب معادل 62%، 60%، 32% و 38% بود. ماده مؤثره در سه فرمولاسیون EC، SL، WP و pH در فرمولاسیون SC بیشتر از سایر شاخص‌های کنترل کیفی دچار تغییرات غیر قابل قبول شده بود. هم‎چنین نتایج نشان داد آفت‌کش‌های تولید داخل از ماندگاری بالاتری نسبت به تولیدات هندی/ چینی در فرمولاسیون EC برخوردار بوده‌اند.

چکیده [English]

In many cases environmental contamination with hazardous and harmful wastes is irreversible. Expired pesticides stockpiles in worldwide warehouses are considered as one of these types of wastes. Lack of attention to these warehouses makes the horrible effects to human’s health and environment. This study investigated the possibility of recycling the expired pesticide stockpiles of agricultural supportive services company. Quality control tests were performed according to the FAO, CIPAC and pesticide manufacturers' guidelines.The results were classified based on the date of production, type of formulation, quality control parameters and EC formulations manufacturers. Data were analyzed by Chi-Square test, in case of significance; the risk test was performed to determine the relative risk for the variables. Result showed a no-significant correlation between the time lagged after production of pesticides and percentage degradation of pesticides. The percent degradation of EC, SC, WP and SL formulation were 62%, 60%, 32% and 38 % respectively. Active ingredient in three formulations included EC, SL, WP and pH in SC formulation were unacceptable changes more than other the quality control parameters.Also, theresults showed that pesticides with EC formulations were produced in the country have more durability than Indian/Chinese.
