on June 24, 1980 at this station, shows a degradation (or dissolution) 

 of the alkylated cycloparaf fins to C3 and C4 . Concerning the thio- 

 phenic derivatives, some benzothiophenic alkyls disappear to become 

 C5, while the initial alkylate derivatives of dibenzothiophene become

In the sampling taken in January 1980, an abnormally high res-
