To this mixture, 0.25 M sodium carbonate buffer (2 mL) and 0.5 M tetrabutylammonium hydrogen sulfate (TBAHS) solution (1 mL, adjusted to pH 10) were added and mixed thoroughly. The extraction of target compounds was performed by the addition of 5 mL of methyl-tert-butyl ...
GC–MS/MS confirmed the identities of the compounds detected by GC. None of the pesticides found in kaki, cashew apple and guava was authorised for these crops in Brazil. The risk assessment has shown that the cumulative acute intake of organophosphorus or pyrethroid compounds from the ...
