The health ministry has come out with a decree that should benefit those living near construction sites.
The ministry said that operators who generate dust must take steps to mitigate it.
That might just mean covering piles of construction materials to prevent the wind carrying away some. Or it might mean covering trucks that are hauling dirt and materials.
The decree cites both public and private projects, although it does not seem to cover those gravel roads in the country where vehicles create dust bowl conditions.
The ministry said that dust can worsen allergies and can lead to skin diseases or respiratory illnesses. A lot depends on the weather conditions at the time, it said.
Project managers also are supposed to maintain access roads so they are not sources of dust, perhaps by spraying them with water.
