افزایش چشمگیر پسماندهای پلاستیکی در اقیانوس‌ها از دهه ۱۹۹۰

نتایج یک مطالعه نشان می‌دهد حجم پسماندهای پلاستیکی در اقیانوس‌ها از دهه ۱۹۹۰ افزایش چشمگیری داشته‌ است.

به گزارش ایسنا، کارشناسان انگلیسی به بررسی اطلاعات جمع‌آوری شده طی مدت ۶۰ سال پرداخته و نتیجه گرفتند که در فاصله سال‌های ۱۹۵۷ تا ۲۰۱۶ تعداد پسماندهای پلاستیکی موجود در اقیانوس‌ها افزایش چشمگیری داشته‌ است. اشیاء پلاستیکی از قبیل کیسه، طناب و تور از جمله پسماندهایی هستند که در اقیانوس‌ها پیدا می‌شود.

همچنین محققان اظهار داشتند: قدیمی‌ترین زباله پلاستیکی کیسه‌ای بوده که سال ۱۹۶۵ از آب‌های شمال غرب ایرلند بیرون کشیده شده‌ است.

محققان در این بررسی از دستگاه جمع‌آوری کننده پلانکتون‌ها استفاده کردند. هدف اصلی این دستگاه‌ها جمع‌آوری پلانکتون‌ها بوده اما طی دهه‌های گذشته این دستگاه‌ها برای جمع‌آوری دیگر پسماندها از جمله میکروپلاستیک‌ها و ماکروپلاستیک‌ها مورد استفاده قرار گرفته‌اند.

میکروپلاستیک‌ها تکه‌های کوچکی هستند که بزرگی آن‌ها کمتر از پنج میلی‌متر است. ماکروپلاستیک‌ها قطعات بزرگتری از پسماندهای پلاستیکی هستند.

به گزارش روزنامه ایندیپندنت، بر اساس این مطالعه همچنین حجم ماکروپلاستیک‌های موجود در اقیانوس‌ها از دهه ۱۹۹۰ به طور چشمگیری افزایش پیدا کرده‌ است.
