Coumaphos is a common organophosphorus pesticide used in agricultural products. It is harmful to human health and has a strictly stipulated maximum residue limit (MRL) on fruits and vegetables. Currently existing methods for detection are complex in execution, require expensive tools and are time consuming and labor intensive. The surface plasmon resonance method has been widely used in biomedi...

A highly sensitive and rapid food-screening test based on disposable screen-printed biosensors was developed, which is suitable for monitoring infant food. The exposure of infants and children to neurotoxic organophosphates and carbamates is of particular concern because of their higher susceptibility to adverse effects. The European Union has, therefore, set a very low limit for pesticides in ...

Residues of benzoylphenylurea insecticides (diflubenzuron, hexaflumuron, and flufenuxuron), carboxamide acaricides (hexythiazox), and carbamate insecticides (benfuracarb) were determined in 150 orange fruit samples from September 1998 to June 1999, to estimate exposure of the Valencian population to oranges contaminated with these newly developed pesticides. The method for monitoring these resi...

A high-performance liquid chromatographic (HPLC) method for the simultaneous determination of tilmicosin, tylosin, spiramycin, and its major metabolite neospiramycin was developed that is suitable for porcine, bovine, and poultry muscles. Macrolide residues were extracted from muscle with acetonitrile, fat was removed by liquid-liquid extraction with isooctane, and the extract was then cleaned ...

Abstract As veterinary drugs available for fish is very restricted, there growing trials repurposing livestock as aquatic animal drugs. Tylosin one of the most effective antibiotics to treat bacterial infections approved livestock, and would be used in fish. Hence, we investigated toxicological microbiological aspects tylosin establish health-based guidance value (HBGV) maximum residue limit (M...

A multiresidue quantitative screening method covering 39 antibiotics from 7 different families by ultra-high-pressure-liquid-chromatography-tandem mass spectrometry (UHPLC-MS/MS) is described. Sulfonamides, trimethoprim, tetracyclines, macrolides, quinolones, penicillins and chloramphenicol are simultaneously detected in liver tissue. A simple sample treatment method consisting of extraction wi...

Zearalenone (ZEN) is a mycotoxin of the genus Fusarium which belongs to group macrocyclic lactones. ZEN contamination occurs during cereal harvest or in early phase storage if drying was insufficient. The aim this study determine level feed mixtures given pigs fattening period at three different farms Republic Croatia, as also levels urine and meat taken from same animals. examined correlation ...

Herbicide residue analysis has gained importance worldwide, mainly for food quality control to minimize potentially adverse impacts on human health. A Gas chromatography-tandem mass spectrometry (GC-MS) method quantitative of acetochlor and s-metolachlor in maize soybean straw been developed, validated applied analyze the residues anilide herbicides. Straw material was dried, homogenized extrac...

Insecticide, acaricide, nematicide and metabolite residues were assayed in 104 potato samples collected from local markets Tokat, Türkiye 2022 the potential health risk for consumers assessed. Analytical method verification was performed 135 pesticide active substances matrices by liquid chromatography-tandem mass spectrometry gas chromatography-mass spectrometry. Matrix-matched calibration cur...

Abstract We aimed to quantify spray drift-based exposure of fruits and vegetables grown in gardens or allotments next agricultural areas plant protection products (PPP). The amount drift transported into during the treatment tall growing crops field was simulated. Two different test systems an outdoor wind tunnel were used, approximating conditions for application both crop types. For experimen...
