Bisphenols are increasingly recognized as environmental pollutants with endocrine-disrupting potential. Nonetheless, the study of environmental occurrence and some endocrine-disrupting activities of some bisphenols came widely into focus of research only recently. The aims of the present study were to: 1) determine the predominant bisphenols in Nor...

Treated wastewater ponds (TWPs) serve as recipients and passive tertiary treatment mediators for recycled water. These nutrient-rich habitats are increasingly utilised in aquaculture, nevertheless multiple loads of various contaminants with adverse effects on aquatic fauna, including fish, have been recorded. In the present study, we investigated t...

In this research was aimed to investigate the sensitivity to drug (ivermectin) in Kangal and Akbaş breed dogs, which are dog breeds native to Turkey, via the MDR1 gene mutation. For the research, blood, hair and intraoral swap samples were taken from 30 Kangal and 20 Akbaş breed dogs (male female mixed, adult) with ethical permission and approval f...

In this study, it was aimed to determine the kinetics of florfenicol (FF) given intramuscularly and gavage in a single dose (10 mg/kg) in Black Sea Turbot (Psetta maxima), whose growing possibilities were investigated in Turkey in recent years. The study was carried out in black sea water, in closed system pools within the Trabzon Fisheries Central...

From the past to the present, teleost fishes have played a significant role as the source of protein for both humans as well as animals. Within the rising world’s population and developing technologies, aquaculture is the fastest expanding market and one of the significant contributors to global food production. However, there are critical concerns...

Fundamentals of Aquatic Veterinary Medicine provides systematic, highly practical guidance on the treatment of aquatic mammals, amphibians, fish, and invertebrates in veterinary practice. Mapping to each of the nine core areas of the WAVMA Certified Aquatic Veterinarian (CertAqV) Program, this comprehensive clinical reference covers taxonomy, anat...

Gelişmekte olan su ürünleri endüstrisi hayvansal protein üretiminin önemli bir miktarını karşılamaktadır. Ancak nüfusun giderek artması, iklim değişikliği, çevresel bozulmalar ve özellikle hastalıklar üretimi etkilemekte, bu durum ise ülke ekonomisini makro düzeyde etkilemektedir. En sık karşılaşılan hastalık etmenleri Aeromonas spp., Vibrio spp.’d...

Permanent organic pollutants (POPs) are chemicals that can remain intact in nature for a long time and affect the health of humans, animals and the environment. In this study, cytotoxicity and 7-Ethoxyresorufin O-deethylase (EROD) activity of water (6 stations) and sediment (12 stations) samples collected from Ankara Stream for 12 months were evalu...

The effects of biofloc technology (BFT) on growth and hepatopancreas histology of speckled shrimp Metapenaeus monoceros (initial weight: 8.32±0.69 g) were investigated for 30 days. The trial was conducted in fiberglass tanks (45 L) with biofloc (zero-water exchange) and without biofloc (water exchange 50% day-1). Different carbon sources (corn s...

The aim of this study was to determine, muscle residue level (MRL) and withdrawal time (WT) of florfenicol (FF), in healthy and infected rainbow trout (Oncorhynchus mykiss) with Lactococcus garvieae. Fish were divided into the four groups, Group I (Infected fish fed with FF free diet, n = 10), Group II (Healthy fish fed with FF free diet, n = 10),...

Persistent organic pollutants (POPs) are banned in almost all countries due to their adverse health effects while they are still present in the environment due to their persistence. As the dissipation and the emission factors of POPs change by temperature and other environmental factors current study aimed to determine selected POPs, including poly...

Among environmental contaminants polychlorinated biphenyls (PCBs) are still a concern due to their persistence in environment. As an emerging contaminant, they are directly linked to climate change and few studies are available for their relation between microbiota including bacteria. Antibiotic resistance (AMR) as an increasing global issue, is st...

Organic and conventional animal products may include residues of veterinary drugs and environmental contaminant. Food contaminants can cause consumer illness such as allergy, immunosuppression, cancer, teratogenicity, mutagenicity and genotoxicity. Therefore, their control is an important issue in terms of public health. In this article, informatio...

A new method is reported to determine polychlorinated biphenyls (PCBs) in marine sediments using ultrasound-assisted extraction and dispersive liquid-liquid microextraction with gas chromatography – mass spectrometry. To optimize the method, acetone, acetonitrile, and methanol were characterized for extraction from the sediments. Acetone provided t...

In the current study, organic and conventionally produced rice and lentil samples purchased from the supermarkets in Ankara, Turkey were analyzed for their nutritional composition, nitrate/nitrite content and aflatoxin contamination. Nitrate/nitrite concentrations were found to be significant (p<0.05) only for nitrate (higher in organic) and nitrit...

Veterinary drug residues and their metabolites in food are regularly investigated by local authorities; however their fate in the environment is still unknown. Despite the importance of the aquaculture industry and the widespread use of antibiotics; limited scientific information regarding their residue in natural fish, sediment and sea water are a...

The aim of this study was to evaluate the effects of storage conditions (room temperature, refrigerator) and cooking methods (frying, boiling) on florfenicol (FF) and florfenicol amine (FFA) residue levels in eggs. Without any significant difference between storage conditions at 20˚C and +4˚C, residue levels decreased within days, but were still pr...

Among persistent organic pollutants, polychlorinated biphenyls (PCBs) are subject to restrictions internationally, due to their adverse health effects including endocrine disruption and concern for their residues in several matrices. Sediment is one of the major sinks of PCBs in aquatic environment. The analysis of sediment samples for PCBs levels...

The possibility of using in vitro biomonitoring systems to evaluate the anthropogenic aquatic toxicology as a screening tool especially with regards to the endocrine disrupting chemicals (EDC) is challenging and received importance over the past decade. Growing concern worldwide about human-animal health and wildlife effects of EDCs is focused on i...

The objective of this study was to investigate the effects of hydrolyzed and live forms of yeast products from Saccharomyces cerevisiae on in vitro fermentation of a 50:50 forage:concentrate substrate using the rumen simulation technique (Rusitec). The Rusitec system consisted of nine fermentation vessels: three of them received daily 0.5 g/L hydro...

Abstract 1. The aim of this study was to develop a suitable method for the analysis of florfenicol (FF) and its metabolite florfenicol amine (FFA) in chicken eggs and to determine FF and FFA residue depletion in eggs of laying hens. 2. The analytes were extracted from yolk, albumen, and whole egg by phosphate buffer and ethyl acetate. Following pur...
