Environmental officials in the capital and neighboring Mexico state, which surrounds the Federal District and forms part of the Mexico City metropolitan area, are taking measures to deal with the high levels of air pollution in the region, the Metropolitan Environmental Commission, or CAM, said.
Use of motor vehicles is being restricted and outdoor activities will be limited, the commission said.
Pollution levels hit 150 on the Metropolitan Air Quality Index, or Imeca, in the southeast section of Mexico City on Tuesday afternoon, the CAM said in a statement.
Readings above 100 call for the air to be classified as “bad,” while a level of 150 is considered “very bad” and a reading of more than 200 is “extremely bad,” requiring officials to take drastic measures, the CAM said.
“High pressure in the central region of the country” caused changes in atmospheric conditions on Tuesday, preventing the dispersal of particulates, the commission said.
