Environmental Alert Issued for Santiago on Thursday
An Environmental Alert was issued in Santiago on Thursday after five monitoring stations reported the air quality as ‘regular’.
The Ministry of Transportation and Telecommunications issued the alert after monitoring stations at Quilicura, Cerro Navia, Pudahuel, La Paz and El Bosque all measure air quality in the range of 100 to 199. In La Florida stations reported the air quality between 300 to 400.
Santiago’s Quality of Particulated Air (ICAP) states that levels of PM-10 (particulate matter with diameter of 10 micrometres or less) up to 100 is “good”. Up to 200 is “regular”, and at 200+ it is consider “bad”. It should be noted that in the United Kingdom, the United States and the European Union it is considered a serious pollution ‘episode’ if the PM-10 level exceeds 50.
The air monitoring stations in Las Condes and Parque O’Higgins recorded good air quality, ranging from 0 to 99.
With the Environmental Alert in effect people are forbidden to light any type of wood heaters or any other timber products whether or not it is fitted with a dual combustion chamber, throughout the Metropolitan Region.
There are also restrictions on vehicles without catalytic convertors and the government also recommends people to refrain from physical activity outdoors.
