Spinach is a frequently consumed vegetable worldwide. Chemical pesticides are widely used to produce spinach with high yield and quality. However, the unregulated use of negatively impacts human environmental health. A simple efficient method using dispersive solid-phase extraction (d-SPE) combined field experiments was conducted study residue dissipation methoxyfenozide, chlorantraniliprole, i...

Systematic control of antibiotic residues includes analysis and selection of large number of samples, and requires a wide range of screening methods. Screening tests should satisfy the following requirements: they must be capable to detect antibiotics of interest, detection limits must comply with the requirements (MRLmaximum residue limit), they must be easy to perform and cost effective, test...

Chlorpyrifos® (Thaion Agro Chemical CO., Ltd. Yannawa, Bangkok 10120, Thailand) (an almost water insoluble organophosphate insecticide) has been extensively used, resulting in the presence as a surface contaminant foodstuffs, streams and soils. It is thus critically essential to develop methods degrade or remove eliminate this pollutant from environments. very limited solubility so it primarily...

گوجه ­فرنگی یکی از محصولات پرمصرف در کشور ماست که تولیدکنندگان برای کنترل آفات این محصول به فواصل کوتاه از آفت­ کش­ ها استفاده می­ کنند. به­ علت دوره زمانی کوتاه بین آخرین سم ­پاشی تا برداشت محصول احتمال آلودگی محصول به آفت­ کش در زمان ورود به چرخه مصرف وجود دارد. این مطالعه برای اندازه­ گیری دوره کارنس دو آفت­ کش متداول کلرپیریفوس و دلتامترین صورت گرفت. گوجه­ فرنگی­ ها در 2 گلخانه کاشته شده و ...

A study was performed to determine the residues in edible tissues of healthy pigs after continuous administration of doxycycline with drinking water for five consecutive days at a dose rate of 10.5 mg doxycycline kg-1 body weight (BW) per day. Quantitation was performed using a validated HPLC method with fluorescence detection. The method was able to separate doxycycline and its 4-epimer, 4-epi...

We provide an ex-post econometric examination of the harmonization and tightening of the EU Maximum Residues Limit (MRL) on aflatoxins in 2002, and its impact on African exports of groundnut products. We show that the MRL set by the EU has no significant trade impact on groundnut exports from Africa across various methods of estimation. African domestic supply plays an important role in the det...

Fish from Dutch markets were analysed for concentrations of polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDD/Fs) and dioxin-like polychlorinated biphenyls (DL-PCBs) and compared with the new European maximum residue levels (MRLs), set in 2006. In a first study on 11 different fish and shellfish from various locations, concentrations of PCDD/Fs were nearly all below the MRL for PCDD/Fs [4 p...
