González, Tamaulipas, nestled in northeastern Mexico, occupies a geographically significant position within the state's industrial and agricultural heartland. Located at approximately 22.83°N, 98.43°W, the city sits on a gently sloping plateau, part of the broader Gulf Coastal Plain. The surrounding landscape is characterized by expansive agricultural fields, primarily dedicated to corn and sorghum cultivation, interspersed with scrubland and grasslands. To the east, the terrain gradually descends towards the coastal lowlands, while to the west, it rises slightly. González’s elevation, around 150 meters above sea level, contributes to a relatively stable atmospheric layer, which can, under certain conditions, exacerbate air quality issues. The city’s proximity to the industrial corridor stretching along the US-Mexico border, particularly the Monterrey metropolitan area, means it’s susceptible to transboundary pollution transport. While not directly adjacent to a major river, groundwater resources are vital, and air pollution can impact their quality. The urban–rural gradient around González is relatively sharp; the city transitions quickly into agricultural land, with smaller rural communities scattered throughout the surrounding plains. This interplay between agricultural practices (fertilizer use, burning) and industrial emissions creates a complex air quality profile. The prevailing winds, generally from the northeast, often carry pollutants from the industrial belt towards González, influencing local air quality patterns. The flat terrain limits dispersion, potentially trapping pollutants during periods of low wind speed.

González experiences a subtropical climate with distinct wet and dry seasons, significantly influencing its air quality. The dry season, typically spanning from March to June, often sees heightened particulate matter concentrations. Reduced rainfall and increased temperatures lead to drier soils, promoting wind erosion and dust emissions from agricultural fields. Furthermore, the lack of precipitation limits the natural cleansing effect of rain, allowing pollutants to accumulate. Temperature inversions, common during this period, trap cooler air near the ground, preventing vertical mixing and concentrating pollutants. Agricultural burning, a traditional practice for land clearing and residue disposal, also contributes significantly to particulate pollution during these months, particularly in April and May. The wet season, from July to October, brings increased rainfall and higher humidity, generally improving air quality by washing away pollutants and promoting atmospheric stability. However, heavy rainfall can occasionally lead to flooding, which can release pollutants from contaminated sites. November and February represent transitional periods, with fluctuating temperatures and wind patterns, leading to variable air quality. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry season, limiting outdoor activities during peak pollution episodes. Maintaining indoor air quality through proper ventilation and air filtration is also advisable. Agricultural workers should utilize appropriate respiratory protection when exposed to dust and smoke from burning practices.
