Antagonism produced by hypertonic nutrient solutions on the depressive effect of carbofuran on isolated guinea pig atria
(Academic Press Ltd, 1996-04-01)
The action of hyperosmotic nutrient solutions on the depressive effects of carbofuran was studied on spontaneously contracting guinea pig atria. The force and frequency of contraction were recorded using an isotonic lever. ...
On-line extraction and determination of carbofuran in raw milk by direct HPLC injection on an ISRP column
(Vieweg, 1998-01-01)
A method has been developed for extraction and determination of carbofuran in milk. The method involved direct injection of raw milk on to a human serum albumin dimethyloctyl-silica gel (HSA-Cs) column and the use of 80:20 ...
DEVELOPMENT OF A BIOMIMETIC SENSOR MODIFIED WITH HEMIN AND GRAPHENE OXIDE FOR MONITORING OF CARBOFURAN IN FOOD
(Elsevier B.V., 2014-11-10)
A biomimetic sensor based on a carbon paste electrode modified with hemin complex and graphene oxide was developed as an alternative technique for the sensitive and selective analysis of carbofuran pesticide. The electrochemical ...
Camouflaging of seeds treated with pesticides mitigates the mortality of wild birds in wheat and rice crops
(São Paulo - Escola Superior de Agricultura Luiz de Queiroz, 2010)
Seeds used to plant wheat, corn and rice crops in Brazil are treated with the insecticide carbofuran associated with the dye rhodamine B, attracting granivorous birds and causing mortality during sowing. The objective of ...
Determination of carbofuran and 3-hydroxycarbofuran residues in coconut water by solid-phase extraction and liquid chromatography with UV detection
(Taylor & Francis Inc, 2006-01-01)
A simple method was developed to determine carbofuran and 3-hydroxycarbofuran in coconut water. The procedure involved solid-phase extraction using C-18 cartridges with acetonitrile for elution. The analysis of these ...
Combining electrochemically reduced graphene oxide and Layer-by-Layer films of magnetite nanoparticles for carbofuran detection
(Elsevier B.V., 2020-10-01)
Carbofuran (CBF) is a pesticide currently prohibited in many countries. It can cause serious damages in the nervous system and has been associated with cancer. However, CBF residues are still found in food samples around ...
Residues of carbosulfan and its carbofuran metabolites and 3-hydroxy-carbofuran in oranges
(Sociedade Brasileira de Fruticultura, 2004-08-01)
The objectives of this study were to evaluate the residues of the insecticide carbosulfan and its carbofuran metabolites and 3-hydroxy-carbofuran in orange compartments (whole fruit, bagasse and juice) and comparison between ...
Histological Changes in Targeted Organs of Nile Tilapia (Oreochromis niloticus) Exposed to Sublethal Concentrations of the Pesticide Carbofuran
(2020-05-01)
This study aimed to evaluate histological changes in targeted tilapia organs exposed to sublethal concentrations of carbofuran. Fishes with an average weight of 67.5 ± 2.0 g were exposed to sublethal concentrations (0.0044, ...
