A multi-residue method was developed for monitoring antibiotic residues in milk using liquid chromatography coupled to a tandem quadrupole mass spectrometer (LC/MS-MS). Two very short extractions followed by two LC/MS-MS acquisitions allowed the screening of 58 antibiotics belonging to eight different families (penicillins, cephalosporins, sulfonamides, macrolides, lincosamides, aminoglycosides...

Abstract Chlorpyrifos is an organophosphate insecticide. It has low aqueous solubility, volatile and non-mobile, moderately persistent in soil, highly toxic to mammals, acetylcholinesterase inhibitor. The main use of chlorpyrifos control various types agricultural pests. This study aims determine the absorption residues maize plants. was conducted July-December 2019. Experimental research at Ja...

A qualitative method for the screening of organophosphorus pesticides (OPs) that could present in different types of vegetables has been established and validated. A typical multi-residue extraction procedure of OPs using ethyl acetate and sodium sulphate has been applied. No clean-up was required after extraction, and concentrated extracts were analysed by gas chromatography with pulsed-flame ...

The study was carried out to detect and quantify the left over residue of fenvalerate acephate in tomato yard long bean using Gas Chromatography coupled with Flame Thermionic Detector. Four supervised field trials were undertaken sprayed prescribed dose at rate 1mL/L water 2g/L water. samples collected 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 15 days after spray (DAS). detected up 11 DA...

Oxfendazole, methyl-5 (6)-phenylsulfinyl-2-benzimidazole carbamate, is a member of the benzimidazole family of anthelmintics. Anthelmintic benzimidazoles are widely used in meat producing animals (cattle, sheep and pigs) for control of endoparasites. The extensive use of veterinary drugs in food-producing animals can cause the presence of small quantities of the drug residues in food. Maximum r...

Over 800 pesticides are currently approved for use in one or more EU countries. The maximum residue levels (MRL) for agricultural pesticides are derived from field trials conducted under good agricultural practice (GAP). The MRL is a legally enforceable limit related to GAP. The results from field trials would only be used to establish MRLs if the estimated intake of residues did not exceed the...

On the occasion of quality controls in food business and during official food surveillance, didecyldimethylammonium chloride (DDAC) residues in excess of the currently applicable maximum residue level (MRL) of 0.01 mg/kg were detected in food. The first opinion on DDAC residues, which was issued by the Federal Institute for Risk Assessment (BfR) on 29 June 2012 (BfR opinion No 024/2012, availab...

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 ...

Part A: " Organic foods are not healthier than non-organic foods/Organic foods are unhealthy " Misconception Number 1: Pesticide residues in conventional foods are always within safe levels. Summary of Counter-Arguments-A significant percentage of conventional food products contain pesticide residues in excess of legally-defined, maximum, authorized residue limits in Europe and the US.-As a res...
