A gray New Year’s Day pall hangs over Guadalajara. Air contamination in the metro area did not improve with the arrival of a new year. On January 1, readings at four of the city’s nine monitoring stations registered pollution levels higher than 100 Imecas, considered “poor” air quality. The highest reading – 120 Imecas – was recorded at the Miravalle station in the southern part of Guadalajara.
