This study determined pesticide residue levels in some fruits Tokat province, Turkey and assessed health risks associated with the residues. A analytical method was validated to determine 260 pesticides by using liquid chromatography–tandem mass spectrometry (LC–MS/MS). Pesticide solutions (10 50 µg kg­¹) were applied pesticide-free apple matrix for validation of method. The linearities (R2), l...

abstract- crop residue is applied to amend soil properties and increase crop yield. in this study, the effects of rapeseed residues and different rates of nitrogen on grain yield and yield components of sunflower and weed dry matter were investigated. the experiment was conducted at the experimental farm of college of agriculture, shiraz university, located at badjgah, shiraz, iran in 2007-2008...

This report represents the conclusions of a Joint FAO/WHO Expert Committee convened to evaluate the safety of residues of certain veterinary drugs in food and to recommend maximum levels for such residues of food. The first part of the report considers general principles regarding the evaluation of residues of veterinary drugs within the terms of reference of the Joint FAO/WHO Expert Committee ...

In this study, tetracycline group antibiotic residue was investigated in plain and flavored UHT milk of different brands. A total 90 samples (62 28 flavored) were analyzed by ELISA method. Tetracycline residues detected all as a result the analysis. The mean level determined 6.98±0.38 ppb 6.53±0.48 milk. Residue levels found to comply with legal limits announced European Union (EU) commission T...

satellite imagery was used as a rapid and spatially explicit method to delineate crop residue cover and to estimate the use and intensity of conservation tillage. the potential of multispectral high-spatial resolution of worldview-2 local data was evaluated using 11 satellite spectral indices and linear spectral unmixing analysis (lsua). experimental plots were examined; residue cover was measu...

to study the effects of two irrigation regimes and application of barley residue, zeolite and superabsorbent polymer on forage yield and some physiological traits of maize and sorghum, an experiment was conducted over two years in kerman, iran. a randomized complete block design arranged in a factorial split was used with three replications. two irrigation regimes of normal irrigation and water...

A computational method is presented for characterizing residue usage, i.e., site-specific residue frequencies, in aligned protein sequences. The method obtains frequency estimates that maximize the likelihood of the sequences in a simple model for sequence evolution, given a tree or a set of candidate trees computed by other methods. These maximum-likelihood frequencies constitute a profile of ...

Isolation and enrichment of multiclass pesticides’ residue, namely, fungicides (benalaxyl), herbicides (atrazine), carbamate insecticides (carbofuran), organophosphate (chlorpyrifos), organochlorine (4,4′-DDT), pyrethroid (bifenthrin), were made by combining acetone-based salting-out assisted extraction with the dispersive liquid-liquid microextraction (SADLLME) method, followed high-performanc...
