Sýkorová Goffová Z., Kožárová I., Máté D., Marcinčák S., Gondová Z., Sopková D. (2012): Comparison of detection sensitivity of five microbial inhibition tests for the screening of aminoglycoside residues in fortified milk. Czech J. Food Sci., 30: 314–320. The assessment of detection sensitivity of five microbial inhibition tests (MITs), STAR (screening test for antibiotic residues) with the tes...

The levels of dichlorodiphenyltrichloroethane (DDT), dichlorodiphenyldichloroethylene (DDE), endosulfan, endosulfan sulfate, carbofuran, and cartap which were estimated in the flesh of Catla catla sampled from ten sites of Ravi River between its stretches from Shahdara to Head Balloki were studied to know the level of contamination of the selected pesticides by GC-ECD method. All fish samples w...

Access to high-quality and safe food is a basic need in our community and, consequently, the European Union has defined maximum residue levels (MRLs) for a number of antibacterial compounds. However, despite the obvious demand for quantitative multi-residue detection methods that can be carried out on a routine basis, there is currently a lack in the development of such systems. In particular, ...

Raspberry is one of the oldest fruits, used for millennia in the nutritional and medicinal purposes. Cultivation of this fruit in Poland is quite common because of its complex flavor and pharmacological effectiveness. The objective of this study was to investigate the residue levels of 130 pesticides on raspberries from north-eastern Poland producers during seven years (2005–2011). A risk asses...

A multi-residue method for simultaneous determination of 41 LC-amenable pesticides in rice, belonging to different chemical classes has been developed in Iran by LC-MS/MS. For the first time the pesticides were analyzed simultaneously in a single run using positive electrospray ionization with multiple reaction monitoring (MRM) after extraction with slightly modified QuEChERS method. The calibr...

A method for simultaneous determination of residues of six organophosphorus pesticides in animal liver samples has been developed and validated. The method is based on the extraction of organophosphorus pesticides with a mixture of acetone-petroleum ether, clean up on a gel permeation chromatography, further clean up on a small silica gel column, and finally determination by gas chromatography ...

Antibiotics, such as benzyl-penicillin (PenG) and cephalosporin, are the most common compounds used in animal therapy. Their massive and illegal use in animal therapy and prophylaxis inevitably causes the presence of traces in foods of animal origin (milk and meat), which creates several problems for human health. With the aim to prevent the negative impact of β-lactam and, in particular, PenG ...

In this paper, the application of modified genetic algorithms (MGA) in the optimization of the ARX Modelbased observer of the Pneumatic Artificial Muscle (PAM) manipulator is investigated. The new MGA algorithm is proposed from the genetic algorithm with important additional strategies, and consequently yields a faster convergence and a more accurate search. Firstly, MGA-based identification me...

Ozone-based treatment trains offer a sustainable option for potable reuse applications, but nitrosamine formation during ozonation poses a challenge for municipalities seeking to avoid reverse osmosis and high-dose ultraviolet (UV) irradiation. Six nitrosamines were monitored in full-scale and pilot-scale wastewater treatment trains. The primary focus was on eight treatment trains employing ozo...

In this assay, edible cattle tissues from local markets of Ardabil, a Province of Iran, were examined for residues of tetracycline antibiotics (tetracycline, oxytetracycline and chlortetracycline). In total, 110 samples of triceps, gluteal muscle, diaphragm, kidney and liver were randomly obtained from the local markets of the city of Ardabil. Solid-phase extraction (SPE) and high-performance l...
