I am in a similar situation - as I sit here typing this reply, looking out to the front of my small home - I have one construction site behind me (about 20 metres from where I am sitting - with noisy equipment (and often shouting workers) going from about 7 am until around 5-6 pm) and another construction site about 50 metres to my right. All windows have to be closed most of the day, and one door slightly open, due to all the dust coming inside, from these sites.

When will this critical health problem be seriously addressed?
Maybe only after the powerful Thai business families realise that the pollution that their industries are producing is killing more and more of their potential customers and workers (but they can always import more workers from overseas), and thus impacting their obscene profits.
In any case, these powerful families have already sent their children and grand children overseas for secondary and tertiary education, and in the process they have foreign citizenship, and sizeable assets in those countries. The wealthy can always escape (see the Taksin example); the masses cannot.
This has been talked about for many years, if not decades ... over which time next to nothing has been implemented.
Maybe by 2600 (Buddhist Era) something may be finally implemented, just before large parts of Bangkok are permanently under sea water.
Why not ban all new and experimental medical treatments?

It is called iatrogenesis - read Ivan Illich's 1974 book "Medical Nemesis".
As hinted at previously, have you asked any airlines if they would be willing to take him and if so under what conditions, eg accompanying nurse, guardian, etc.?
Is his niece willing to take care of him?
Globalisation = Neoliberal ideology propagated by the rich with the aim of making them super rich and gaining control of the world's resources. In part achieved by billionaires "buying" influential politicians and political parties.
Much the same as Emperor Xi's Belt and Road Initiatives.
