Abstract - Pesticide (vinclozolin, iprodione and methyl tiophanate) residues were determined in honey, pollen and bee bread from a plantation of cherry (Prunus cerasus) cv. English morello. The least contaminated were honey samples, which contained up to 0.1 mg·kg-1 and pollen with up to 0.25 mg·kg-1, and the most contaminated was bee bread with up to 23.6 mg·kg-1 of the used fungicides. Obtained results suggest that residues of vinclozolin and iprodione present in pollen grains are chemically modified (possibly conjugated) and thus undetected by the method used. During fermentation of bee bread the conjugates are hydrolysed and free pesticides released. Experiments showed that both vinclozolin and iprodione applied to old leaves were transported to young leaves and flowers. Thus, despite contact mode of action declared by producers, they also show systemic properties. This assumption may be corroborated by the dynamics of pollen contamination (4-5 days of lag period between the spray time and time of incidence of maximum contamination). © Inra/DIB/ AGIB/Elsevier, Paris

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access.

An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

  • If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
  • You can define your own OpenURL resolver with your EDPS Account.
    In this case your choice will be given priority over that of your library.
  • You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see You should disable this module if you wish to use the OpenURL server that you or your library have defined.
