2 Sustainable production and management of biological resources from land, forest and aquatic environment Activity 2.1: Sustainable production and management of biological resources from land, forest and aquatic environment

3 KBBE : Deepened and enlarged cooperation between phytosanitary (statutory plant health) research programmes - ERA-NET Funding scheme: Coordination and Support Action (supporting action). The requested European Community contribution shall not exceed EUR requiring enhanced research efforts. The aim is to prevent the introduction into the community of organisms harmful to plants or plant products or their spread within the Community. Due to climate changes and globalization, new threats are continuously emerging and the number and complexity of plant health problems increases every year, requiring enhanced research efforts.

4 KBBE : Integrated pest management in farming systems of major importance for Europe Funding scheme: Collaborative Project (large scale integrating project). The requested European Community contribution shall not exceed EUR better targeted use of all available pest control measures, including preventive measures, observation and pest monitoring, pesticides and biocontrol agents, modelling and experimentation, including physiological and molecular understanding of plant-pathogen interactions and development of symptoms targeting farming systems in which reduction of pesticide use and better control of pests and pathogens is expected to have major effects at the European scale

5 Jaká jsou rizika pro konzumenty? Je lepší volit bioprodukty?

6  Samples from Czech market 23 extra virgin olive oils from organic farming (O1 – O23) 23 extra virgin olive oils from conventional farming (C1 – C23)  Method of analysis GCx GC/TOF MS GCx GC/TOF MS EXTRA VIRGIN OLIVE OIL The oil obtained from the fruit of the olive tree solely by mechanical or other physical means under the conditions. particularly thermal conditions, that do not lead to alternations in the oil, and which has not undergone any treatment other than washing, decantation, centrifugation and filtration. OLIVE OIL

7 Sum of 16 PAH = Sum of B[a]A, Chr, CP[cd]P, 5-MeChr, B[c]Fln, B[b]F, B[k]F, B[j]F, B[a]P, DB[ah]A, B[ghi]P, I[cd]P, DB[ah]P, DB[al]P, DB[ai]P, DB[ae]P PAHs in olive oil Benzo(a)pyrene)
