Determination of Eleven Organophosphorus Pesticide Residues in Textiles by Using HPLC-HRMS.

Analytical sciences : the international journal of the Japan Society for Analytical Chemistry

Hu TT, Lu CM, Li H, Zhang ZX, Zhao YH, Li J.
PMID: 28890486
Anal Sci. 2017;33(9):1027-1032. doi: 10.2116/analsci.33.1027.

The overuse of organophosphorus pesticides on cotton production is a big concern in China today. Therefore, developing methods for the rapid screening and confirming of pesticide residues in textiles has become a top public health security priority. Here, a...

Ozone as degradation agent of pesticide residues in stored rice grains.

Journal of food science and technology

de Ávila MBR, Faroni LRA, Heleno FF, de Queiroz MELR, Costa LP.
PMID: 29085152
J Food Sci Technol. 2017 Nov;54(12):4092-4099. doi: 10.1007/s13197-017-2884-1. Epub 2017 Sep 26.

This work aimed to study the kinetics of bifenthrin and deltamethrin residues degradation in rice grains under exposure to ozone and evaluate the effect of ozonization on rice grains marketing standards. The grains sprayed with pesticides were exposed to...

Stereoselective Behavior of the Chiral Herbicides Diclofop-Methyl and Diclofop During the Soy Sauce Brewing Process.

Chirality

Lu Y, Zhang D, Liao Y, Diao J, Chen X.
PMID: 26501920
Chirality. 2016 Jan;28(1):78-84. doi: 10.1002/chir.22545. Epub 2015 Oct 26.

Chiral pesticides are now receiving more and more attention in the food-making process. This experiment studied the enantioselective behavior of diclofop-methyl (DM) and its main metabolite, diclofop (DC), during the soy sauce brewing process. Two kinds of commonly used...

A wind tunnel for measuring the gaseous losses of environmental chemicals from the soil/plant system under field-like conditions.

Environmental science and pollution research international

Stork A, Witte R, Führ F.
PMID: 24234380
Environ Sci Pollut Res Int. 1994 Dec;1(4):234-45. doi: 10.1007/BF02986536.

Volatilization from treated areas is a major source of pesticide residues in air, fog, and rain. This may lead to long-range transport of pesticide residues to remote areas. Up to now most information on pesticide volatilization has come from...

Determination of Trichlorfon Pesticide Residues in Milk via Gas Chromatography with μ-Electron Capture Detection and GC-MS.

Toxicological research

Hem L, Khay S, Choi JH, Morgan ED, Abd El-Aty AM, Shim JH.
PMID: 24278518
Toxicol Res. 2010 Jun;26(2):149-55. doi: 10.5487/TR.2010.26.2.149.

The pesticide trichlorfon is readily degraded under experimental conditions to dichlorvos. A method has therefore been developed by which residues of trichlorfon in milk are determined as dichlorvos, using gas chromatography with μ-electron capture detection. The identification of dichlorvos...

Assessment of Pesticide Residues in Human Blood and Effects of Occupational Exposure on Hematological and Hormonal Qualities.

Pakistan journal of biological sciences : PJBS

PMID: 29023046
Pak J Biol Sci. 2016;19(3):95-105. doi: 10.3923/pjbs.2016.95.105.

Pesticides are the first choice by farmers for use against plant pathogens, nevertheless their adverse effects to the environment. Current study was designed to measure pesticides residues in blood of spray farmers and to assess their possible effects. Blood...

Farmers' Exposure to Pesticides: Toxicity Types and Ways of Prevention.

Toxics

Damalas CA, Koutroubas SD.
PMID: 29051407
Toxics. 2016 Jan 08;4(1). doi: 10.3390/toxics4010001.

Synthetic pesticides are extensively used in agriculture to control harmful pests and prevent crop yield losses or product damage. Because of high biological activity and, in certain cases, long persistence in the environment, pesticides may cause undesirable effects to...

Pesticide Residues in Commercial Lettuce, Onion, and Potato Samples From Bolivia-A Threat to Public Health?.

Environmental health insights

Bolivia does not have a surveillance program for pesticide residues in food. The few published studies have suggested that pesticide contamination in food may present a public health problem. Data are lacking for all foods except tomatoes and breast...

Detection of pesticides in popular medicinal herbs: a modified QuEChERS and gas chromatography-mass spectrometry based approach.

Journal of food science and technology

Tripathy V, Saha A, Kumar J.
