Comparative study on the fatty acid composition of two marine vertebrates: striped dolphins and loggerhead turtles.

The fatty acid composition of total lipids extracted from seven different tissues (fat, liver, cerebrum, cerebellum, lung, kidney and muscle) of 10 striped dolphins (Stenella coeruleoalba) (weight 75.7 +/- 16.2 kg) found dead or moribund during a morbillivirus epizootic, and from two tissues (fat and liver) of 54 loggerhead turtles (Caretta caretta) (18.

Animal poisonings: the 10-year experience of a veterinary analytical toxicology laboratory.

Data on 10-y of chemical toxicological analyses carried out in a veterinary laboratory in Barcelona, Spain for suspected wild and domestic animal poisonings are summarized. The 218 cases involved more than 1 million animals, some 7,500 of which died. Pesticides, especially insecticides (46.

Organochlorine residues in tissues of striped dolphins affected by the 1990 Mediterranean epizootic: relationships with the fatty acid composition.

A simple and rapid method was developed for the simultaneous determination of fatty acids, organochlorine pesticides, and polychlorinated biphenyl (PCB) congeners in the same sample in order to explore possible connections between levels of contaminants and fatty acid composition. The method was applied to samples of melon, cerebrum, cerebellum, lung, liver, kidneys, and skeletal muscle obtained from 5 male and 5 female striped dolphins (Stenella coeruleoalba) found stranded in 1990 in the northeastern Spanish coasts during the morbillivirus epizootic that affected this cetacean in the Mediterranean Sea. The results indicate that PCBs were dominant in all tissues, with the highest geometric mean concentration being found in melon (903 micrograms g-1 wet wt); sigma DDTs were also found at high concentrations (111 micrograms g-1 wet wt, in melon).
