Marine nanoparticles

Human-made nanoparticles are either engineered, purposely designed and used e.g. in paint and food additives, or incidental, undesired byproducts from combustion, mechanical wear or mineral processing. Marine nanoparticles aimed to better understand the impact of nanoparticles on the marine environment.

The first project goal was establishing a screening method for determining nanoparticles in the marine environment using single particle inductively coupled plasma mass spectrometry (SP-ICP-MS). This method was implemented to better understand the distribution and accumulation of NPs in the marine environment. Incidental nanoparticles from the fine-particulate fraction of mining waste deposited into the ocean through submarine tailings deposition was one subtopic of interest.
