Surprised this hasn't been covered here before. Seems to jump to a lot of conclusions without evidence, but, some interesting points:
"From the historic development of geo-engineering techniques the mixture of both amorphous and mono-crystalline Al2O3 and mono-crystalline (Ba, Srx)TiO3 can be derived as the three most common compounds. But these crystalline particles do not show up in standard chemical analysis, unless one uses hydro-fluorine acid, which is hardly ever the case. Regarding the fact that these crystals are manufactured on-board in spray-pyrolysis within the jet engines, the widely measured fingerprint should be understood as the rejects of the Al2O3 production as well as the of the (Ba, Srx) TiO3 nano-particle production, or as deriving from additional chemicals that could not be identified yet."
"On one hand the link of retarded plant growth and elevated values of barium and strontium as reported by other environmental groups could be confirmed. Regarding the mechanism of bio-accumulation the content of heavy metals was in a range to be considered as being dangerous to mammals and humans. Still, compared to countrywide values and experience with heavy metal pollution from the early times of industrialization as well as the acid-rain area in the 70s, the total values of aluminum, barium, strontium and titanium were in a range that had to be considered as not toxic enough as bio-available elements to explain the damage observed at the plants themselves. Under the premises that there is a connection between the values in heavy metals found and the affection of plant growth the only solution was to look for non-soluble particles containing aluminum, barium, strontium and/or titanium that were affecting plant growth not due to their chemical, but due to their mechanical, electromagnetic or optical properties."
"From the metals contained in barium-strontium-titanate only barium has been sufficiently monitored by state authorities. The data from Germany covering the last 15 years show that the values of airborne barium referred to as dry deposition went down by 95%. This is accredited to improved industrial standards and reduced industrial exhaust. There is also a significant reduction seen in other heavy metals. Pollution deposited with rain is measured through the absorption of the pollutants in grass and referred to as wet deposition. This is a bit misleading because actually it covers both wet and dry deposition. During the same period, values for this composite wet and dry deposition of barium have been almost doubled. For the year 2012 the data gathered from private rain samples directly reveal an average of 0.003 mg barium per liter from which one can calculate a wet deposition of 865 t of Barium on the German territory per year – this value is supported by the data of the state authorities for wet deposition, last published for the years 2009-2011. Being specifically bound to rain, the detected barium must be considered as originating from aerosols of unknown origin, since industry and mining can be canceled out as sources."
