RP247 Environmental risk assessment for shipwrecks: a fault-tree model to assess probability of contaminant release H. Landquist, I. Hassellov, Chalmers University of Technology / Shipping and Marine Technology; L. Rosen, Chalmers University of Technology / Civil and Environmental Engineering; F. Lindgren, Chalmers University of Technology / Shipping and Marine Technology; I. Dahllof, The Plastic preproduction pellets are found in environmental samples all over the world and their presence is often linked to spills during production and transportation. To better understand how these pellets end up in the environment we assessed the release of plastic pellets from a polyethylene produ … Alexander Hassellöv is on Facebook.

AV: From 2011 – 2012 he worked with Prof. Martin Hassellov in a second post-doc at the University of Gothenburg on sensitive detection methods for engineered nanoparticles in complex environmental samples, mainly based in single-particle ICP-MS.

Heteroaggregation of engineered nanoparticles (ENPs) with suspended particulate matter (SPM) ubiquitous in natural waters often dominates the transport behaviour and overall fate of ENPs in aquatic environments.
Heteroaggregation of engineered nanoparticles (ENPs) with suspended particulate matter (SPM) ubiquitous in natural waters often dominates the transport behaviour and overall fate of ENPs in aquatic environments. In order to provide meaningful exposure predictions and support risk assessment for ENPs, environ Application of single particle ICP-MS (spICPMS) for measurement of the size and number concentration, cp, of nanoparticles is currently hampered by insufficient accuracy.
Manufactured and unintentionally produced nanoparticles have been of environmental concern owing to potential harm to humans and ecosystems, but very little is known of the actual concentrations of these owing to limitations of available methods. In order to understand both the potential adverse effects and the underlying natural processes, improved measurement Given the previously mentioned complexities, physical and chemical characterisation of NPs in suspensions is a difficult task, although there are a variety of analytical and metrological techniques available (Hassellov et al., 2008, Tiede et al., 2009, Wigginton et al., 2007) (), which can in principle measure all relevant parameters. Additionally, it is extremely difficult to differentiate ENMs that are expected in low concentrations from NNMs and the natural background during analysis (Duester et al., 2014, Hassellov et al., 2008, Howard, 2010, Kammer et al., 2012, Tiede et al., 2008, Walser and Gottschalk, 2014). 3.1.

Since the start of commercial plastics production in the 1940s, global production has rapidly accelerated, doubling approximately every 11 years. Despite this increase and clear evidence of plastics loss into the oceans, including a substantial standing stock, previous research has not detected a temporal trend in plastic particle concentration in the surface ocean.

Using a generalized Heteroaggregation of engineered nanoparticles (ENPs) with suspended particulate matter (SPM) ubiquitous in natural waters often dominates the transport behaviour and overall fate of ENPs in aquatic environments. In order to provide meaningful exposure predictions and support risk assessment for ENPs, environ Although atmospheric transport and deposition could be an important pathway of terrestrial pollutants to the ocean, little information concerning the presence and distribution of these suspended atmospheric microplastics in marine air is available. We investigated, for the first time, the occurrence and distribution of suspended atmospheric microplastics (SAMPs) in the west Pacific Ocean.
