Qualidade do ar melhora na Cidade do México e no Estado do México, evitando rodízio duplo de veículos

A qualidade do ar na Cidade do México e no Estado do México melhorou, evitando a ativação de uma nova contingência de ozônio em meio a uma onda de calor. Às 15h, apenas a estação Tlalpan registrava qualidade ruim, Cuajimalpa boa e as demais aceitável. A Comissão Ambiental da Megalópole (CAMe) encerrou a contingência do fim de semana e mantém alertas para condições de estabilidade atmosférica.

A fase 1 da contingência ambiental, suspensa no domingo, não foi reativada na segunda-feira, apesar dos altos níveis de poluição decorrentes de uma onda de calor e de um sistema anticiclônico que favorece o acúmulo de ozônio.

O programa Hoy No Circula foi aplicado normalmente na terça-feira, 28 de abril, das 5h às 22h, para veículos com selo rosa e finais de placa 7 ou 8. As isenções incluem motocicletas, veículos elétricos, híbridos categoria I e II, hologramas 00 e 0, entre outros.

Esta é a sexta contingência de 2026 no Vale do México; as anteriores foram causadas por partículas PM2.5 e ozônio. A CAMe prevê estabilidade atmosférica, ventos fracos e temperaturas acima de 30°C para a semana de 27 de abril a 1º de maio.

A CAMe recomendou a redução de emissões: limitar o uso do carro, abastecer fora dos horários de pico, evitar aerossóis e solventes, reduzir o tempo de banho e reparar vazamentos de gás.

The Comisión Ambiental de la Megalópolis (CAMe) has decided to maintain Phase I ozone air contingency in the Mexico City Metropolitan Area on Saturday, February 14, 2026, marking the third day of vehicle restrictions due to poor air quality. The peak ozone level recorded was 156 ppb at the Atizapán station in the State of Mexico. Authorities attribute the situation to a high-pressure system that promotes pollutant accumulation.
