Influence of Environmental Conditions on Chemical Leaching and Sorption to Microplastic Debris – 2013

Research investigating the influence of environmental parameters on chemical sorption and leaching to/from microplastics

Project Abstract

Scientists at the Virginia Institute of Marine Science are investigating the influence of a suite of environmental parameters on the processes that govern chemical sorption and leaching to/from microplastic debris. In particular, the project uses laboratory techniques to investigate the following:

  1. the leaching of persistent, bioaccumulative, and toxic (PBT) substances from four classes of synthetic polymers;
  2. the sorption from water of two PBT mixtures to two classes of synthetic polymers;
  3. and in the process, will investigate the influence of polymer size, weathering, biofouling, and environmental parameters (e.g., temperature, salinity) on sorption and leaching processes.

The influence of these environmental conditions will be compared and contrasted to develop a broader understanding of environmental influences on the chemical impacts of microplastics.This research project is ongoing.
