Chemtrails contain aluminum and barium sulfate.Or one could call them aerosols in the air. They last longer then the old comtrails.

Absolute twaddle! There are no "chemtrails". The longevity of condensation trails or contrails depends on the amount of moisture in the upper troposphere and the presence of supersaturated air. Contrails have been known and understood (except by chemtrail nutters) since aircraft began flying at high altitudes in the 1930s. During World War II, bombers used contrails to their advantage. They climbed to the level at which contrails started then went a little lower so they left no trail. Any fighters coming from above would leave contrails and could be seen.
The height and duration of condensation trails can be forecast using a temperature sounding of the atmosphere from a weather balloon. There is nothing remarkable, strange or new about them - and no-one is trying to poison you.
