Named three cities with the dirtiest air in the world

A study by an international group of environmentalists has helped identify major cities that boast the most polluted air.

In this far from the most honorable rating, the first place was taken by New York with an air quality index of 185.

According to experts, large-scale forest fires, which have been raging in southern Canada for several weeks, have helped worsen the environmental situation in the largest city in the United States.

Also in the top three "leaders" were Israeli Tel Aviv and the American Detroit with an index of 157 and 154, respectively.
