Abstract:
... Ocean acidification and plastic pollution are considered as potential planetary boundary threats for which crossing certain thresholds could be very harmful for the world's societies and ecosystems well-being. Surface oceans have acidified around 0.1 units since the Industrial Revolution, and the amount of plastic reaching the ocean in 2018 was quantified to 13 million metric tonnes. Currently, bo ...

Gaertn. pectin (NPGP) was found to synergistically interact with sodium alginate (SA) under an acidification process by glucono-δ-lactone (GDL) addition. This synergistic interaction led to the formation of much stronger NPGP/S ...

This makes it important to determine in what quantitates they occur in aquatic systems like seawater. However, even when using the most sensitive ICP-MS technique, quantification of very low seawater concentrations of ENPs is still concept rather than the fact. To approach ...
