Nanchital de Lázaro Cárdenas del Río, nestled within the state of Veracruz, Mexico, occupies a geographically significant position within the southern Gulf Coastal Plain. Located at approximately 18.0667° latitude and -94.4167° longitude, the city’s terrain is characterized by gently sloping lands transitioning into the low-lying coastal plains typical of the region. The surrounding landscape is a mosaic of tropical rainforest remnants, agricultural fields (primarily sugarcane and maize), and scattered settlements. The Coatzacoalcos River, a major waterway, flows nearby, influencing local humidity and microclimates. Nanchital’s elevation is relatively low, averaging around 10-30 meters above sea level, which can exacerbate air pollution episodes due to limited vertical dispersion of pollutants. The city’s proximity to the Coatzacoalcos River and the Gulf of Mexico introduces a maritime influence, often resulting in higher humidity and fog formation, particularly during the wet season. Further inland, the presence of industrial activity concentrated in the Coatzacoalcos metropolitan area, including petrochemical plants and refineries, contributes to regional air pollution. The urban-rural gradient around Nanchital is gradual, with agricultural lands gradually giving way to more densely populated areas. This interplay of coastal plains, riverine influence, agricultural practices, and industrial proximity collectively shapes the city’s environmental conditions and significantly impacts its air quality profile. The prevailing winds, generally easterly, play a crucial role in transporting pollutants both into and away from the city.

Nanchital de Lázaro Cárdenas del Río experiences a tropical wet and dry climate, dictating a distinct seasonal pattern in air quality. The dry season, typically from March to May, often sees a slight improvement in air quality due to increased wind speeds and reduced humidity. However, agricultural burning, a common practice for land clearing and crop residue disposal, can significantly elevate particulate matter concentrations during this period, creating localized pollution events. The wet season, spanning June to October, brings frequent rainfall and higher humidity, which generally helps to cleanse the atmosphere by scavenging pollutants. However, periods of stagnant air, particularly during the transition months, can lead to the build-up of pollutants. November to February represents a transitional period, with cooler temperatures and occasional fog, which can trap pollutants near the ground, especially during temperature inversions. These inversions, common during the cooler months, prevent vertical mixing and concentrate pollutants. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during periods of agricultural burning and when fog or temperature inversions are present. Outdoor activities are generally more favorable during the wet season, but vigilance is still required. The combination of humidity, temperature, and wind patterns creates a dynamic air quality environment, requiring ongoing monitoring and public awareness campaigns to mitigate potential health risks. The prevalence of tropical storms and hurricanes during the wet season can also temporarily improve air quality by dispersing pollutants, but the associated flooding can introduce other environmental hazards.
