Chlorophyll fluorescence as a marker for herbicide mechanisms of action
(Academic Press Inc. Elsevier B.V., 2012-03-01)
Photosynthesis is the single most important source of 02 and organic chemical energy necessary to support all non-autotrophic life forms. Plants compartmentalize this elaborate biochemical process within chloroplasts in ...

Simultaneous determination of pesticides in fruits by using second-order fluorescence data resolved by unfolded partial least-squares coupled to residual bilinearization
(Hindawi, 2018)
Abstract: In the present work, a chemometric-assisted spectrofluorimetric method has been developed for the simultaneous determination
of natural fluorescent pesticides, carbaryl, carbendazim, and thiabendazole, in orange ...
Chlorophyll fluorescence as a marker for herbicide mechanisms of action
(Academic Press Inc. Elsevier B.V., 2014)
Four-way kinetic-excitation-emission fluorescence data processed by multi-way algorithms. Determination of carbaryl and 1-naphthol in water samples in the presence of fluorescent interferents
(Elsevier Science, 2010-09)
Four-way data were obtained by recording the kinetic evolution of excitation-emission fluorescence matrices for samples containing the analytes carbaryl and 1-naphthol, two widely employed pesticides, in the concentration ...
Chitosan nanoparticles loaded the herbicide paraquat: The influence of the aquatic humic substances on the colloidal stability and toxicity
(Elsevier B.V., 2015-04-09)
Polymeric nanoparticles have been developed for several applications, among them as carrier system of pesticides. However, few studies have investigated the fate of these materials in the environment in relation to colloidal ...
