Chile: High air pollution in central regions June 5 /update 1

Event

High levels of air pollution continue to be reported in towns throughout central Chile as of early Tuesday, June 5. A purple “emergency” alert, the highest level, is in effect in the commune of Chillán. Red “pre-emergency” alerts, one step lower, are in effect in Rancagua, Linares, Talcahuano, Los Ángeles, Curanilahue, Padre Las Casas, Valdivia, and Osorno. Lower orange and yellow alerts are in effect in various other areas, including parts of the capital Santiago. These adverse conditions could continue into the coming days.

Driving and industrial restrictions are possible in the above areas.

Context

Pollution levels tend to rise in Chile during the (southern hemisphere) fall and winter period.

High pollution levels can cause eye, nose, and throat irritation and aggravate cardiovascular and respiratory conditions (such as asthma). During periods of high air pollution the government typically advises against all outdoor exercise and recommends that schools cancel physical education classes. Vulnerable individuals - e.g. children, seniors, pregnant women, and people suffering from asthma and other respiratory issues - should be particularly cautious and consider wearing masks covering their nose and mouth when outdoors.

Advice

Individuals present in the above areas are advised to monitor the situation in the coming days, limit outdoor activity, and adhere to any instructions issued by the local authorities.
