摘要:

Different tissues from salmon treated with the quinolones oxolinic acid, flumequine, enrofloxacin and sarafloxacin were analysed in search of possible reservoirs of the drugs. Residues of oxolinic acid and flumequine seem to be especially bound to bone, enrofloxacin to skin, and sarafloxacin to both skin and bone. The results showed that residues of these drugs were present in the fish for prolonged periods after the end of treatment.

摘要:

The consumption of plutonium, americium and radiocaesium in locally collected shellfish is an important contributor to the radiation dose received by seafood consumers living in West Cumbria. Only a small fraction of the actinide activity is assumed to be absorbed via the gut whilst it is assumed that all the radiocaesium is. Solubilization studies reported here using anin vitrodigestion method support the former assumption but not the latter, suggesting that the proportion of the137Cs available for absorption could be significantly smaller than unity where a large percentage of the ingested Cs is adsorbed onto inorganic sedimentary material. Such a situation arises near the Sellafield nuclear‐reprocessing plant where a high proportion of the radiocaesium (and plutonium) in the winkles collected locally and subsequently cooked is associated with inorganic particulate matter.

摘要:

A method for the measurement ofo‐tyrosine in irradiated chicken has been developed. The procedure involves the solvent extraction and removal of freeo‐tyrosine, which is present in unirradiated tissue, followed by acid hydrolysis of boundo‐tyrosine in the proteinaceous residue and measurement of the cleaved residues by HPLC with fluorescence detection. Boundo‐tyrosine was not detected above 0.01 mg/kg in unirradiated tissue but was observed, in increasing amounts of up to 5.18 mg/kg, when the tissue was irradiated at doses of between 2.5 and 20 kGy. The precision of the analysis was assessed by duplicate determinations, the agreement between duplicates and their respective means averaged 1.7% as defined by the term [(a‐ b)/(a + b)]×100% whereaandbare the repeat determination values.

摘要:

Information on the dietary intake of chemical contaminants has been obtained from institutions participating in GEMS/Food. Contaminants studied include certain organochlorine and organophosphorous pesticides, PCBs, cadmium, mercury, and lead. The intakes are compared with toxicologically acceptable intake levels established by international expert groups.
