"I want to inform you that the environmental contingency was lifted after 19 hours because the pollutants were scattered because we do not have the anticyclonic condition, the moisture that has reduced fires in the area The country's power station has increased, the temperature has decreased the environment and contributed to the decrease in vehicle traffic these days, "he said.
