Did you attempt to find the answers? I googled dust in Doha and it took me about 2 minutes to find out:

Results of monitoring minute particles in the air show increase in pollution rates in Doha, where
minute particles amount raised from (128.78) microgram/cubic meter of air in 2007, to (155.7)
microgram/cubic meter in 2010, i.e. an annual growth rate of (%5.4). This increase is attributed
mainly to sand storms, that Qatar face as natural phenomenon, without omitting other pollutant
sources, e.g. transportation, where Doha is considered one the most car using cities in the world
compared to its population, in addition to that the effect of manufacturing, specially cement
industry, which discharge many aerial plankton and dust, and the unprecedented activity in
construction of infrastructure witnessed by the State, and its impact of pollutants.

The international permitted level for this type of atmospheric pollution is 50 microgram/cubic meter of air.

And yes, these are statistics collected by the Qatar Government.

I can't really be bothered checking the rest of these points. Frankly I'm surprised that the number of people dissatisfied with garbage disposal is on 65%. I would love to meet the people who think that it's perfectly acceptable to throw crap out the window of your car, and that having open top skips with feral cats rummaging inside is the way we should be living in a "modern city".
