Electrochemical sensing of methyl parathion on magnetic molecularly imprinted polymer
(2018-10-30)
The electrochemical detection of methyl parathion in fish was performed by preconcentrating the pesticide on magnetic molecularly imprinted polymer and further readout on magneto-actuated electrode by square wave voltammetry. ...
Dynamics and orientation of parathion dissolved in a discotic nematic lyomesophase
(CSIRO Publishing, 2008)
Parathion, an organophosphorous pesticide, presents serious hazards to the environment and health. It inhibits acetylcholinesterase, an enzyme incorporated in the cell membrane. A study on the behaviour of parathion in a ...
Layer-by-Layer Films of Graphene Nanoplatelets and Gold Nanoparticles for Methyl Parathion Sensing
(Amer Chemical Soc, 2019-02-01)
The wide use of pesticides in agriculture makes necessary the development of cost-effective, easy, and rapid methods aiming for environmental and health protection. We propose the fabrication and investigation of layer-by-layer ...

Cortisol response to acute stress in jundiá Rhamdia quelen acutely exposed to sub-lethal concentrations of agrichemicals
(2008-09-01)
Exposure to agrichemicals can have deleterious effects on fish, such as disruption of the hypothalamus-pituitary-inter-renal axis (HPI) that could impair the ability of fish to respond to stressors. In this study, fingerlings ...

Square wave adsorptive cathodic stripping voltarnmetry automated by sequential injection analysis - Potentialities and limitations exemplified by the determination of methyl parathion in water samples
(ELSEVIER SCIENCE BV, 2008)
This paper describes the development and evaluation of a sequential injection method to automate the determination of methyl parathion by square wave adsorptive cathodic stripping voltammetry exploiting the concept of ...
Eficácia do paration metílico e do extrato aquoso de folhas secas de nim no controle de anacanthorus penilabiatus (monogenoidea) em pacu (piaractus mesopotamicus)
(Inst Pesca, 2008-01-01)
This work determined the efficacy of the insecticide methyl parathion and the natural pesticide azadirachtin present in the aqueous extract of dry neem leaves (AEDNL) to Anacanthorus penilabiatus (Monogenoidea) control in ...
