“جزيرة النفايات الكبرى” سبب تغير لون المحيط الهادئ

ما يعرفه ريفو عن الخبر

ترتبط التغيرات في لون المحيط الهادئ بتراكم جسيمات البلاستيك الدقيق وتشكل بقعة النفايات الكبرى.
يساهم تراكم النفايات البلاستيكية في تعزيز الإشعاع في الجزئين الأخضر والأزرق من الطيف الضوئي.
تسمح هذه الخصائص البصرية باستخدام تغيرات لون المحيط لمراقبة انتشار البلاستيك وقياس تركيزه بدقة.
يدخل سنويا نحو 300 مليون طن من النفايات البلاستيكية إلى مياه الصرف والمكبات ولا تتحلل لمعظمها.

اكتشف علماء فيزياء من أوروبا أن التغيرات في لون بعض المناطق الشمالية في المحيط الهادئ التي رصدتها الأقمار الصناعية على مدى 20 عاما مرتبطة بتراكم جسيمات البلاستيك الدقيق في عمقه.
