Je. Conde et al., SOURCES OF TAR BALLS AND OIL-SLICKS ON THE COASTS OF THE CANARY-ISLANDS, International journal of environmental analytical chemistry, 62(1), 1996, pp. 77-84
Tar balls and oil slicks were sampled on several beaches in the Canary
Islands and analyzed, along with reference crude oils, for n-alkanes
and polycyclic aromatic hydrocarbons by gas chromatography and spectro
fluorimetry, respectively. Statistical treatment of the data including
intercorrelations, Factor Analysis and Cluster Analysis allow the ide
ntification of most of source-crudes.
