In 2010, my life changed when Dr Henk Tennekes and I traded books. His was: The systemic insecticides: a disaster in the making and ours was: The Year of the Bumblebee: Observations in a small Nature Reserve. Dr Henk Tennekes, an independent toxicologist based in the Netherlands, was the first researcher to recognise the extreme toxicity of low levels of systemic neonicotinoid insecticides that have become widespread in the environment.

Auf großes Interesse stieß am Mittwoch der Vortrag von Dr. Henk Tennekes, (Experimental Toxicology Services Nederland), zum Einsatz von Pestiziden. Im Saal der Gaststätte „Meta“ in Hesel mussten zusätzliche Stühle aufgestellt werden, damit jeder der rund 200 Besucher einen Sitzplatz erhielt. Die Vorsitzende des Kreis-Imkerverbandes, Almuth Janßen aus Hesel, war als Veranstalterin „schlicht erschlagen von der großen Resonanz“, wie sie sagte. Tennekes stellte seine in jahrelanger Forschung ermittelten Untersuchungsergebnisse in wissenschaftlicher Form mit vielen Daten und Tabellen dar.

Expenditure for discovery and development of a new crop protection product is now approaching the $ 300 million mark, while at the same time underpinning information gaps in environmental safety assessment. Large information gaps also exist for the safety of a vast number of existing chemicals in commerce. Addressing safety information gaps of new and existing chemicals with increased conventional toxicity testing would skyrocket costs and animal usage and contravene the 3Rs principles to refine, reduce, and replace animal testing.

Attached is a PDF slideshow, of the Keynote/ Powerpoint the British environmentalist and beekeeper Graham White presented in California to the American Beekeepers Federation in 2014. He also gave the same slideshow and talk to the directors of the Sierra Club - the most influential environmental NGO in the USA. This was presented as a Webcast from the Pesticide Research Institute in Berkeley to several hundred beekeepers who logged in to their website from all over the States.

In the 1950s the commission on food coloring of the German Research Society (DFG), headed by the biochemist Adolf Butenandt and the pharmacologist Hermann Druckrey, represented a policy of preventive risk management in regard to food additives. Druckrey had conducted animal tests with butter yellow, an azo compound used to give butter an attractive yellow colour. These experiments demonstrated that the production of tumours required a certain total dose, regardless of how this was distributed over 35 to 365 days.
