Marine Pollution with Hazardous Chemicals and Monitoring

Abstract

In recent years, numbers and amounts of hazardous chemical substances used for industrial and domestic purposes have rapidly increased. It is said that these substances are finally accumulated in seawater and sediment. However, the distribution and the temporal variation of the hazardous chemical substances in marine environment have not been clarified yet in a global scale due to the limited number of observation data. I believe that more frequent spatial and temporal observations are required in order to understand the marine pollution mechanism.
