GC-ECD evaluation of dicofol toxicity to tropicalAstyanax bimaculatus schubarti

Chromatographia, 1996
Evaluation of the toxicity of Dicofol was carried out onAstyanax bimaculatus schubarti, a characteristic fish species living in tropical rivers and lakes. Experiments were under laboratory controlled conditions with atmospheric air flow and dilution water at 25°C in the static mode.

Determination of OCDD and OCDF in Soils and Biological Samples by GC/ECD

1991
This paper describes advancements in the gas chromatography-electron capture detector (GC/ECD) determination of octachlorodibenzodioxin (OCDD) and octachlorodibenzofuran (OCDF). OCDD and OCDF (OCDD/F) serve as markers or surrogates for the more toxic polychlorinated dibenzodioxins and dibenzofurans (PCDD/Fs).

Improvement of sensitivity in the determination of organochlorine pesticides using a PSS injector with GC-ECD

Analytical and Bioanalytical Chemistry, 2004
This paper describes the optimisation of a PSS injector in a gas chromatograph with a programmed pneumatic control (PPC) for the determination of 21 organochlorine pesticides. The injection of high volumes of sample (20 microl) improves the detection limits and allows a reduction in the amount of sample processed. The injection conditions were selected

Pesticide Residues Determination in Vegetables from Romania by GC-ECD

2009
Pesticide use raises a number of environmental concerns. Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, including non-target species, air, water, bottom sediments and food. Pesticide drift occurs when pesticides suspended in the air as particles are carried by wind to other areas, potentially

[Specific determination of deltamethrin and tralomethrin by preparative HPLC and GC-ECD].

Kokuritsu Iyakuhin Shokuhin Eisei Kenkyujo hokoku = Bulletin of National Institute of Health Sciences, 1998
Tralomethrin quickly changes to deltamethrin in gas chromatograph by debromination. Therefore deltamethrin and tralomethrin are not able to be distinguished by gas chromatographic determination. A method for specific determination of deltamethrin and tralomethrin was established.

DI-SPME for the Determination of Pesticide Traces in Tomato by GC-ECD

2013
The use of pesticides in agriculture has grown dramatically over the last decades. Environmental exposure of humans to agrichemicals is common and results in both acute and chronic health effects. In this study, the DI-SPME technique coupled with GC/ECD was developed for trace determination of nineteen chlorinated pesticides in tomato samples by using ...
