FOREWORD 



These Proceedings result from the third symposium held by Project 02.02- 

 13 under the aegis of the US-USSR Joint Agreement in the Field of Environ- 

 mental Protection, established in May, 1972. 



Both broad review and narrowly specific papers were presented by parti- 

 cipants from both countries in an effort to continue the joint procedural, 

 technological and methodological exchange and familiarization begun at the 

 two preceeding symposia in 1975 and 1976. Learning does not occur de novo 

 and subsequent understanding and application must be based on a foundation 

 of fact. The atmosphere of mutual interest, candor and respect which sur- 

 rounded this symposium enabled another series of steps in the learning pro- 

 cess. Perhaps the philosphy underlying this symposium, and the project it- 

 self is best expressed by an old saying, which transliterated from the 

 Russian approximates: Vyek zhee-vee, Vyek oo-chee. Live a lifetime, learn 

 a lifetime.
