This technique involved modification of a comonly used procedure.2
The a c i d i c e x t r a c t s were analyzed f o r n i c k e l and vanadium content on a PerkinE l m e r Node1 403 atomic absorption spectrophotometer; standard s o l u t i o n s were
prepared and t h e o p e r a t i n g conditions were e s t a b l i s h e d i n accordance w i t h t h e reconmendation of t h e manufacturer. RESULTS AND DISCUSSION
The average s e a s o n a l d i s t r i b u t i o n s of vanadium and n i c k e l during 1972 a r e presented i n Table 1. Both metals show s t r o n g s e a s o n a l f l u c t u a t i o n s t h a t are i n v e r s e l y p r o p o r t i o n a l t o t h e average seasonal, ambient temperature.

Since samples were a v a i l a b l e f o r t h e y e a r 1966 a t many Boston l o c a t i o n s , i t was decided t h a t a one-month period in t h e w i n t e r would b e analyzed f o r

The
purpose of t h e intended comparison was t o determine t h e e f f e c t of r e g u l a t i o n s imposed during t h e i n t e r v e n i n g y e a r s t h a t s e v e r e l y l i m i t e d t h e combustion of r e s i d u a l f u e l oils i n favor of t h e cleaner burning d i s t i l l a t e f u e l s .
As

A s can be observed i n Table 3, n i c k e l and
vanadium concentrations were narkedly higher in Eastern Massachusetts during 1966 because of t h e increased use of r e s i d u a l f u e l o i l s during t h a t period. During t h e r e c e n t energy c r i s i s t h e r e has been considerable s p e c u l a t i o n a s t o t h e e f f e c t of burning r e s i d u a l o i l s of high s u l f u r content i n s t a t i o n a r y power p l a n t s and t h e impact which t h i s s i t u a t i o n n i g h t have on t o t a l contamfnat i o n of t h e atmosphere.
