Gentamicin residues in eggs from 50 ISA brown laying hens were analysed using HPLC-fluorescence. The recovery study showed that approximately 90% of the gentamicin could be recovered from the egg. The lowest detection limit was 0.01 μg/g in the whole egg. The retention times of the combined peaks of three components of gentamicin were 4.0 to 4.1 min. Their initial concentrations of the gentamicin residues were retained for up to fourteen days at both refrigerated (+4°C) and room temperatures (15°-20°C), but started to lose strength on day 21 of storage. On the 28 th day, gentamicin residues in the eggs kept at room temperature were lower than those kept at the refrigerated temperatures. The different cooking procedures did not affect the ge...

Çevre kirliliğine neden olan maddeler çevrede kalıcılıklarına göre biyolojik olarak parçalanabilen ve parçalanmayan olmak üzere 2 sınıfa ayrılırlar. Biyolojik olarak parçalanabilen kirleticiler, çev-rede kolayca dekompoze olurlar ve yalnızca geçici sorunlara neden olurlar. Metaller, plastikler, bazı pestisitler, deterjanlar ile radyoetkin izotoplar gibi çevrede biyolojik olarak parçalanmayan maddeler ise uzun süreli ve kalıcı olumsuzluklara neden olurlar. Bunların çoğunluğu petrol rafine-rileri, organik kimya ve sentetik kimya endüstrileri, demir-çelik ile madencilik, tekstil ve kâğıt en-düstrilerinden kaynaklanır. Bu nedenle bu derlemede insan, hayvan ve bitki sağlığını sürekli tehdit eden ve biyolojik olarak parçalanmayan kirleticiler ve toksisiteleri üzerinde durulmuştur. Sonuç olarak sanayi tesislerinde kurulması zorunlu olan atık arıtma tesislerine rağmen, özellikle geliş-mekte olan ülkelerde çevrede bulunan önemli miktarda kirletici olumsuzluklara neden olabilir. İnsan/hayvan ve çevre sağlığının bu türden kirleticilerin olumsuz etkilerinden korunabilmesi için sıkı kurallar konulması ve bunlara uyulmasının sürekli denetlenmesi gerekir.

Biologically degredable contaminants are decomposed easily in the environment and cause only temporary problems. Among biologically nondegredable substances; metals, plasticizers, some pesticides , detergents and radioactive isotopes stay in the environment for a long time and cause adverse effects.

They were equally divided into two groups, control and experimental. The animals in the experimental group were intraperitoneally injected with amitraz at a dose of 1 mg/kg body weight. One hour after amitraz injections, erytrocyte, hematocrit, hemoglobin levels and also percent hemolysis of erytrocytes were measured in the blood samples taken from the control and experimental groups. In the experimental group, the value of hemoglobin was lower while the value of methemoglobin was higher than those of the control group (p

Without any significant difference between storage conditions at 20˚c and +4˚c, residue levels decreased within days, but were still present on day 28. Frying and boiling for 1 and 5 min yielded similar results to the storage conditions just described; there was a significant decrease in residue levels, but still not enough for decomposing. these findings indicate that FF and FFA residues are heat-labile.

These lipophilic pollutants are persistent in the environment and able to bioaccummulate in nontarget organisms. BPA, DEHP and PCB118 (dioxin-like PCB) are associated with endocrine disruption effects, while information on their effects on aquatic invertebrates are limited. In the current study, the effects of these compounds, which are ubiqutous and present at low concentrations in the environment, are studied in the primary hepatopancreas, muscle, gill, intestine and gonadal cultures of narrow-clawed crayfish (Astacus leptodactylus Eschscholtz, 1823), a widely distributed freshwater crayfish in Turkey with high economic importance. IC50 values following MTT assay ranged 0.27-12.61 nM; when compared with other tissues, the gonads were more affected with lower IC50 values. PCB118 induced higher cytotoxicity, while DEHP was the least toxic compound. This is the first study on the primary culture of A. leptodactylus¸ and the toxic effects of these compounds in this organism providing mechanistic insights on the responses and detoxification capacity of the organs. This study provides basis to unravel the mechanism of action of the tested EDCs in crayfish and improvement of cell culture conditions for ecotoxicity and screening assays.
