 not polluted, to what degree, and the measures that must 

 be taken to alleviate the polluted conditions. 



Determination of water pollution through 

 measurements of primary productivity and the use of the 

 Pacific oyster embryo bioassay technique was critically 

 commented upon by the pulp and paper industry. 



Referring first to the primary productivity 

 studies, we feel that this matter was resolved by the 

 speakers and the conference chairman. However, for the 

 record we have attached a report (Westley, I967) indicating 

 the interactive effect of sulfite waste liquor on photo- 

 synthesis in estuarial waters. 



With regard to the oyster larvae bioassay, 

 we feel that most of the questions are adequately answered 

 in Appendix I of the original statement presented by the 

 Washington Department of Fisheries to the conferees and

 Oyster Embryo Bioassay" submitted for the record as part 

 of this supplement. 



However, we will take this opportunity to 

 offer our comments on some statements made by Messrs. 

 Donald Benson, Gene Haydu, and Roger Tollefson. We must
