Israeli study: Seasonal streams release microplastics into the Mediterranean Sea in “release” waves after rains

An Israeli study has revealed that seasonal streams are dumping large amounts of microplastics into the Mediterranean Sea. In the summer, the plastic particles accumulate, and during the rains, they are released in a large wave into the sea.
