In general, aquatic invertebrates are substantially more sensitive to petroleum hydrocarbons than algae (Mahoney and Haskin, 1980). LC50S of 1-5 mg L have been reported for the water-soluble fraction of many types of crude oil, but this range can be extended to <0.1-100 mg L depending... [Pg.130]

The last class of lipids being considered here are the hydrocarbons. Hydrocarbon markers include alkanes derived from algae or plant leaves, and polycyclic aromatic hydrocarbons (PAH) derived mainly from crude petroleum and fuel spills. PAH can also be found in combustion products of fuels such as heating oil, gasoline and wood. Coastal sediments act as the ultimate reservoirs for these compounds when they are transported unaltered through the water column. [Pg.205]

The following are examples of TLC analyses in which SFE was the method used for sample preparation lipids in wool (analysis by TLC-FID) hpids in fish feed (TLC-FID) the pesticide chlorpyrifos and its degradation products in soil hydrocarbons in heavy petroleum products (TLC-FID) aromatic and ahphatic hydroperoxides in solid matrices (online sample transfer to TLC plates) colored fractions from a Mediterranean brown alga essential oil in foods " and cyanazine from soil (silica gel TLC-densitometry at 220 nm).
