GC-MS identification of the five most abundant aromatic and aliphatic compounds within the PHC mixture prior to, and after 48 hours of biodegradation.
|Compound||Day 0a||Day 2a|
aPercent the specific compound makes-up of the total PHCs in liquid degradation systems; Day 0 represents the starting percent for these compounds in this study.
bThe number listed represents the listed compounds percent of the total PHCs present in the sample.
cND=Not detectable(Minimum detection limit)
dOne of the two samples was not positively identified by the GC-MS (<90% match with the HP Chemstation library); ± is the standard deviation of two samples when positively identified by the GC-MS.
