Biogeochemical Processes of Natural Organic Matter and Emerging Organic Contaminants in Aquatic Ecosystems

Session ID#: 81704

Session Description:
Large water bodies such as rivers, lakes, and oceans play an important role in the global biogeochemistry of natural organic matter (NOM) and persistent organic pollutants (POPs) in the environment. The development of many novel techniques has tremendously advanced geochemical studies of NOM and its links with POPs. Meteorological conditions can also influence the mobility and fates of NOM and POPs. Understanding and quantifying the global dynamics and sinks of NOM and POPs are important to assess their environmental impacts and fates.

This session will address the new advances of following aspects:

  • Effects of anthropogenic activity and global climate change on NOM source, transport, and transformation in aquatic ecosystem.
  • The coupling relationships of POPs with NOM biogeochemical processes in aquatic environment.

The key factors of burial and sequestration of NOM and POPs in aquatic ecosystem.
