The sorptive properties of natural estuarine colloids were investigated, with the herbicides atrazine and linuron used as model pollutants. Linear Freundlich adsorption constants for atrazine and linuron were 1850 and 6750, respectively. These high values indicate that natural colloids have the potential to be important substrates in the transport of hydrophobic contaminants in aquatic environments.
