Rivers Carry Plastic Debris Into The Sea

Every year, millions of tonnes of plastic debris ends up in the sea - a global environmental problem with unforeseeable ecological consequences. The path taken by plastic to reach the sea must be elucidated before it will be possible to reduce the volume of plastic input. To date, there was only little information available on this. It has now been followed up by an interdisciplinary research team who were able to show that plastic debris is primarily carried into the sea by large rivers.

The decline in emissions also has negative implications

In large parts of Europe and North America, the decline in industrial emissions over the past 20 years has reduced pollution of the atmosphere and in turn of soils and water in many natural areas. The fact that this positive development can also have negative implications for these regions has been demonstrated by scientists at the Helmholtz Centre for Environmental Research (UFZ) in the journal Global Change Biology. According to their findings, declining nitrate concentrations in the riparian soils surrounding the tributary streams of reservoirs are responsible for the increasing release of dissolved organic carbon (DOC) and phosphate and a deterioration in water quality. In the case of drinking water reservoirs this can cause considerable problems with respect to water treatment.
