The link you posted is for a question submitted to the European Parliament in 2012, which has apparently never had an answer. It starts out like this: " According to an Italian blogger," which means it is not a credible source.

Who are these unnamed experts?

How did they collect air samples from contrails tens of thousands of feet up?

Where is the published study?

I'm going to say that since this question has not been answered in 22 years, the European Parliament did not deem it a serious question to answer.

Seriously, any blogger can say anything. Where is the real proof?

Where is the real proof?>>>>>>>>>>>>>>> All hou have to be able to do is observe the difference between spray and contrails. Contrails disappate within an h9ur at the most. Chemtrails have a different texture and are thicker by contrast.Thyey last for hours in the sky and are systematically applied.

The elements of chem trails are from ground sampling after a rain usually, the ontituent eoements are quite strange.All ground has a backgropund level of certain eements. These are detected because the stand out as abnormal after a spraying event.

Suture yourself though. I would not want to stifle any genuine curiosity you might have:
