رودخانه ها ممکن است میکروپلاستیک های بیشتری از آنچه قبلا تصور می شد به اقیانوس های جهان حمل کنند

Rivers may be carrying more microplastics into the world's oceans than previously thought

Microplastics are a modern environmental menace and a potential threat to human health. These tiny pieces of plastic, measuring from 1 to 5,000 micrometers, come mainly from larger plastics as well as sources such as paints and cosmetics. They are found in almost every corner of the planet, and a new study published in Science suggests rivers may be carrying far more of them into the ocean than previously thought.
