Environmental systems can be polluted with nanoparticles and infective particles (viruses, bacteria, parasites) mainly through sewer systems, wastewater discharge, sanitary landfills, septic tanks, and agricultural practices. The presence of biocolloids in environmental systems increases the risk of human infection and disease. Similarly,
engineered nanoparticles may have adverse effects on aquatic biosystems and human health. Consequently, understanding the factors that control fate and transport of biocolloids and nanoparticles in environmental systems is of major significance.

In this session all contributions examining the fate and transport of biocolloids and (engineered) nanoparticles in environmental systems are invited. More specifically the contributions may be focused on:

• fate and transport of biocolloids and nanoparticles in environmental systems
• interactions between biocolloids, nanoparticles and solid surfaces
• biocolloid biodegradation in the presence of solids
• aging and weathering of engineered nanoparticles
• toxicity of products generated from biological disruption of pollutants in the presence of biocolloids
• adverse effects of nanoparticles on aquatic microorganisms
• effects of climate change on biocolloid and nanoparticle migration
• public health risks associated with water and air polluted with biocolloids and nanoparticles
