• Nanomaterials: <100nm in at least 1 dimension
• quantum mechanical effects often dominate
• surface area per unit volume increases
• materials that exhibit unique optical, mechanical, magnet conductive and sorption properties
•Nanotubes:




 • will enter the environment at some stage
 Questions:
 • How do they behave in the environment
 • How do they interact with marine organisms
 • How to they interact with other contaminants

Editor's Notes

  • #10 Apical end of the gill lamellae – cirri are clearly visible as hair-like structures (arrow)
  • #11 Particles (black) caught in gill mesh; cilliar transport towards food groves (Dots on right hand diagramme)
  • #12 Transport of particles incorporated in mucus across the surface of gill mesh
  • #14 Transport of food particles along a food grove.
