Última Passive Sampling in Regulatory Chemical Monitoring of Nonpolar Organic Compounds in the Aquatic Environment ArchiMer Booij, Kees; Robinson, Craig D.; Burgess, Robert M.; Mayer, Philipp; Roberts, Cindy A.; Ahrens, Lutz; Allan, Ian J.; Brant, Jan; Jones, Lisa; Kraus, Uta R.; Larsen, Martin M.; Lepom, Peter; Petersen, Joerdis; Proefrock, Daniel; Roose, Patrick; Schaefer, Sabine; Smedes, Foppe; Tixier, Celine; Vorkamp, Katrin; Whitehouse, Paul. We reviewed compliance monitoring requirements in the European Union, the United States, and the Oslo-Paris Convention for the protection of the marine environment of the North-East Atlantic, and evaluated if these are met by passive sampling methods for nonpolar compounds. The strengths and shortcomings of passive sampling are assessed for water, sediments, and biota. Passive water sampling is a suitable technique for measuring concentrations of freely dissolved compounds. This method yields results that are incompatible with the EU's quality standard definition in terms of total concentrations in water, but this definition has little scientific basis. Insufficient quality control is a present weakness of passive sampling in water. Laboratory performance...

Farmers’ experiments are an integral element of agricultural practice, contribute to the development of local knowledge and form the precondition for local innovations. This study addresses organic farmers’ experiments in Austria, and specifically video as tool for capturing and sharing lessons learned from farmers’ experimentation, as well as the potential of video to trigger farmers’ experiments. For 85 % of the surveyed organic farmers (n=34) farmers’ experiments were considered to have high relevance in the course of their farming activities. The elaborated videos stimulated 71 % of the farmers to conduct experiments. The videos were successfully applicable in adult and student agricultural education. After watching them, 12 of 16 students (75 %) came...

Ano: 2013 URL: http://orgprints.org/21346/1/21346_mayer.pdf A field trial on the effects of pure sodium propionate and a combination with herbal extracts on short term development of subclinical ketosis Organic Eprints Dorn, Katharina; Leiber, Florian; Sundrum, Albert; Holinger, Mirjam; Mayer, Philipp; Walkenhorst, Michael. While glucogenic substances in ketosis prevention are commonly used, there is a lack of clinical studies about the effectiveness of ketosis therapy in particular by means of sodium propionate and herbal extracts. Fresh cows between 5 and 50 days in milk of 25 Swiss and German dairy farms were tested weekly for ketone bodies in blood. From 283 cows, 121 (42.8%) exceeded the threshold of 1.0 mmol/l blood-β-hydroxybutyrate (BBHB). Thereof 84 cows were randomly assigned to three treatments on each farm. Treatment SP-H was composed of sodium propionate (120 g per application) and an aqueous extract of seven herbs (13.5 g drug equivalent per application), treatment SP comprised pure sodium propionate (120 g per application) and treatment PL was a placebo.
