English on Page 2 "Several samples of « air borne filaments » collected in November and December 2012 throughout the french territory were sent to our laboratory (originating from Thénioux, Saint Clément des Levées, Saint Martin de Crau, and Malabat (collection points located on the map of France, page 118). For each of these samples, two Curie-Point thermal desorption experiments were conducted at 445°C, directly as well as after in-situ methylation (a process allowing detection of polar compounds potentially present). The organic compounds generated in this series of eight experiments were -each time- separated by gas chromatography and identified by mass spectrometry (GC/MS). The data obtained were interpreted and the detailled results are presented in this analytical report. It appears that these « air borne filaments » are complex organic polymers, containing many synthetic chemicals, as evidenced by GC/MS screening of their thermal decomposition products. Many organic molecules commonly encountered in the composition of jet fuels and jet reactors lubricants were evidenced in this investigation. The four samples studied contain several toxic synthetic compounds (phthalates) and three of them contain DEHP, a member of this family of particular concern due to its properties of endocrin disruptor. All organic molecules, particularly the heterocyclic compounds, present in the « air borne filaments » samples represent a strong concern, for public health as well as environnemental protection. We think these « air borne filaments » could result from the recombination of substances that are rejected at high altitude in the atmosphere by jet engines. Considering the fast growth rate of the world-wide air transportation industry, the results of our preliminary study should draw the attention of the public opinion and of the media on this new form of atmospheric pollution. Hoping the scientific community will soon begin studies to understand the subject, so that the air transportation authorities can play an efficient role in controlling this new form of global atmospheric" http://www.labo-analytika.com/documents/20131030_Dumas-18_Rapport_analytique_AnAlytikA.pdf
