Aliphatic Hydrocarbons in Birds of Prey from Galicia (NW Spain)

摘要

Eleven aliphatic hydrocarbons, unresolved over resolved ratio (U/R), carbon preference index (CPI), pristane/C17 ratio, and totals were determined in six classes of tissues (heart, liver, intestine, muscle, lung, and kidney) of 10 buzzards (Buteo buteo), 10 barn owls (Tyto alba), and five tawny owls (Strix aluco) from Galicia (NW Spain). Among individuals detected at quantifiable levels, in general, C18 was found to be the most abundant. Total aliphatic hydrocarbons were detected in 77/100 tissue samples. Phytane was detected in only three samples: intestine and muscle of two buzzards and lung of one barn owl.
