Many other materials have a toxic effect on estuarine biota. These 

 materials may be present in various industrial wastes or be by-products 

 of interaction within the estuary. Examples are cyanides from metal - 

 plating wastes and sulfides from the anaerobic decomposition of 

 sewages and industrial wastes. 



Wastes from the chemical industry are highly variable and potentially 

 toxic. Ever-changing chemical technology leads to many new products, 

 each creating a new complex waste disposal problem. 



Included in the consideration of toxic materials are radionuclides 

 discharged to the estuarine waters. Ionizing radiation, when absorbed
