TABLE 4.
Mass balance of penta-, hexa-, and heptachlorobiphenyls dechlorinated to the four major tetrachlorobiphenyl products
 |
a
The decrease for this congener was based on 40% meta dechlorination of the 2345-chlorophenyl ring to a 245-chlorophenyl ring.
b
The decrease for this congener was based on 60% para dechlorination of the 2345-chlorophenyl ring to a 235-chlorophenyl ring.
c
This congener coelutes with 245-25-CB and could not be resolved. It is a likely intermediate, but its contribution could not be determined.
