Topic : Does the plastic pollution of the seas come from the rivers ?
Is the Mediterraean sea polluted ? (see ). According to my readings, this pollution comes from the rivers and it seems logic to look for the sources of such a pollution and for the solutions. In Netherland, an ecological organization has built a barge to collect plastic in a rivers.
 What about collecting wastes from a barge in the rivers (at the least in their estuary) before being in the seas or the oceans ? (is it possible ? for the most polluted rivers ?)
I can imagine that the European Countries are not the only ones to be responsible of the pollution of the mediterranean sea...

But I don't agree with you it's true pollution of sea come from rivers but the large amount of pollution also from sea port or from site. ( )

Dear Ms. A. Nicol,

Your assumption that the majority of marine litter, including plastic pollution, comes from rivers is correct based on our findings within our European environment, state and outlook report. Please see our chapter on the marine environment where it is stated that “Land-based sources contribute the largest proportion of litter, which is mostly transported by rivers or directly discharged from coastal activities.”

This is also backed up by the World Economic Forum that states that 90% of plastic polluting our oceans comes from just 10 rivers ([…]/ ) and by the Ocean Cleanup that states that rivers are the main source of ocean plastic pollution and that 1000 rivers are responsible for roughly 80% of the pollution ( ).

As regards your question on the feasibility of installing barges in rivers to collect waste, please note that the EEA does not develop any innovative technologies and is not in a position to comment on the effectiveness of the various technologies currently being applied in Europe. We could nevertheless suggest that you contact the Ocean Cleanup as they would have some insight of the feasibility and effectiveness of technologies preventing plastic from entering oceans from rivers. Other actors might also be looking into similar types of technologies.

We hope that this may be useful for you.

With kind regards,

My questions, when I read the 500 pages of your report, concerned the evaluation of the pollution : I was doubting because of the opposite information, on your map of the bathing water almost all the rivers seem to be very clean (dark blue). If the Mediterranean Sea is polluted (according to WWF), it is by the people living around this sea, not by the asian countries, right ? Do you believe that the WWF lies on the fact that the Mediterranean Sea is polluted ? (the "plastic continent" in the Pacific Ocean is well-known, but according to the WWF, the Mediterranean Sea is 4x more polluted ! who is responsible : the Chinese people ? Sorry to take their defense in that case).
But thanks to your work, he consciousness of the pollution of the rivers and the seas is now in our mind, I hope of course that the Mediterranean people living around the Mediterranean Sea will take care of that beautiful sea.

As per my opinion, plastic sticks to the ground under the river. It doesn't floats freely towards the see. Of course some of it does, but not all. So the major cause of plastic pollution is not the rivers only. If we throw/immerse the sculptures of our Lords into the sea and they are made of plastic. Then these Sculptures also cause plastic pollution in sea. We do it on Holi festival and Durga Puja. Find details here:

yes I'm also looking for the solution of pollution source. you can see some details here and i also read similar here
