  • Levels of 13 multi-class pesticide residues in Polish honeys determined by LC-ESI-MS/MS
    Publication

    Levels of 13 pesticides in 40 honey samples form Poland are reported. A rapid and sensitive method was developed for the LC-ESI-MS/MS determination of multi-class pesticide residues in honey samples. Liquid-liquid extraction (LLE) on a diatomaceous earth support (requiring the use of small amounts of organic solvent), followed by chromatographic separation on a C18 column and gradient elution were employed. The method quantifies...

  • Nowe metody do badań składników obcych w miodach pszczelich
    Publication

    - Year 2011

    Pszczoły, zbierając nektar, pyłek kwiatowy i spadź narażone są na częsty kontakt ze szkodliwymi substancjami (stosowanymi w rolnictwie) osadzonymi na roślinach i przenoszą te zanieczyszczenia - na powierzchni ciała lub wraz z pożytkami - do ula, i w konsekwencji zanieczyszczenia przedostają się do miodu.W związku z możliwością zanieczyszczenia miodu przez pestycydy należące do różnych klas związków chemicznych, pomocne okazuje...

    - SEPARATION AND PURIFICATION TECHNOLOGY - Year 2011

    The experimental study of transport properties of mixed matrix membranes (MMMs) based on PEBA-4033 with two types of zeolites is reported. Gas (CO2, O2, N2) and vapor (benzene, toluene, methanol, water) permeation measurements were performed using the differential flow permeameter at temperature of 298.15 K and at atmospheric pressure. Gas/vapor permeation was monitored by measuring the changes of the thermal conductivity of carrier...
