SANTIAGO – The second air-quality warning of the year was issued Monday in Santiago due to high levels of pollution, Chilean officials said.
Environmental officials had issued a warning for the capital, home to about 7 million people, on May 22.
In 2016, warnings were issued on 13 days, including one day when an environmental emergency was declared.
Low-level alerts have been issued on more than 20 days this year, with minor restrictions, including keeping a certain percentage of vehicles off the road and limiting the operations of selected industries.
Failure to comply with the restrictions can result in fines being imposed, officials said.
