The present study was undertaken to detect and quantify the left over residue of Diazinon and Carbosulfan in brinjal and Quinalphos in yard long bean and comparison between the detected residue level with maximum residue level (MRL) set by FAO (1970). Three supervised field trials (two for brinjal and one for yard long bean) were carried out sprayed with the field dose (1.5 ml/L of water) of Di...

The depletion times of the anticoccidial nicarbazin administered individually and of nicarbazin and narasin administered in combination were evaluated by determining the presence and levels of 4,4'-dinitrocarbanilide (DNC), the marker residue for nicarbazin, and narasin residues in the muscle tissues of broiler chickens subjected to a pharmacological treatment. A high-performance liquid chromat...

background: tetracyclines (tcs) are broad-spectrumantibiotics that are widely used in veterinary medicine. thepresence of tcs residues in milk is a public health concern allover the world. objectives:this study aimed to determine tcsresiduals in pasteurized milk marketed by some dairy companiesin tehran from april 2011 to march 2012. methods: 432pasteurized milk samples were purchased from supe...

pesticides are one of the major pollutants in the environment. the residue of pesticides has been reported to be at a critical level in agricultural crops, especially in greenhouse crops. tomato is considered as an important vegetable in iranian food basket and is produced in fields and greenhouses. so, the current study aimed to assess diazinon and oxydemeton-methyl levels in tomatoes sampled ...

To assess whether the maximum residue level proposed to CCPR, for use as a MRL, provides sufficient consumer safety, available residue data are combined with cultural dietary information to estimate potential residue intake by consumers. The consumer is considered to be adequately protected when estimated dietary intake of pesticide residues does not exceed the acceptable daily intake (ADI) or ...

On the occasion of quality controls in food business and during official food surveillance, benzalkonium chloride residues in excess of the currently applicable maximum residue level (MRL) of 0.01 mg/kg were detected in food. The Federal Institute for Risk Assessment (BfR) derived toxicological reference values for benzalkonium chloride and assessed whether the detected residues pose a health r...

This study was carried out to determine the pesticide residue levels and health risk assessments in tomato, pepper, cucumber grown Tokat province of Turkey. A analytical method verified 260 pesticides by using a liquid chromatography-tandem mass spectrometry (LC-MS/MS). Pesticide solutions at 10 50 µg kg­¹ doses were fortified with pesticide-free matrix for verification method. The linearities ...
