Gp. Serrazanetti et al., ALIPHATIC-HYDROCARBONS AND LINEAR ALKYLBENZENES IN ZOOPLANKTON FROM THE GULF OF TRIESTE, Chemosphere, 28(6), 1994, pp. 1119-1126
It has been shown that linear alkylbenzenes (LABs) and aliphatic hydro
carbons are present in zooplankton in the Gulf of Trieste. Samples wer
e collected in December of 1990, May and August of 1991. The total hyd
rocarbon levels for August were higher than those for December and May
. This may be explained by high concentrations of biogenic hydrocarbon
s in this period. Odd and even n-alkane distribution in analyzed sampl
es shows a partial contamination by fossil hydrocarbons. Among various
isomers of linear alkylbenzenes, the ones isolated in the greatest qu
antities were generally those with the largest linear chain. We also i
dentified several tetrapropylene alkylbenzenes isomers (TABs), which m
ay still be used for sulfonate detergents in some countries.
