Itāmāti, nestled in the Odisha state of India at approximately 20.1333° N, 85.1500° E, occupies a geographically significant position within the eastern coastal plains. The city’s terrain is predominantly flat, characteristic of the fertile delta region formed by the Mahanadi River and its tributaries. This low-lying landscape, averaging around 30 meters above sea level, contributes to a relatively humid climate and influences local air circulation patterns. Itāmāti is surrounded by a mosaic of agricultural land, primarily rice paddies and pulses, interspersed with small villages, creating a gradual urban-rural gradient. The proximity to the Bay of Bengal, though not immediately adjacent, influences regional weather systems and can contribute to moisture and occasional saline intrusion, impacting atmospheric conditions. While Itāmāti itself is a small settlement, it lies within a broader industrial belt extending along the Odisha coast, with larger industrial hubs located further north and south. These industries, including steel, aluminum, and petrochemical plants, can contribute to regional air pollution, with prevailing winds occasionally transporting pollutants towards Itāmāti. The surrounding landscape, dominated by agricultural fields and scattered settlements, limits the potential for significant topographic barriers that might disrupt air flow, potentially exacerbating the impact of any emissions. The flat terrain also means that pollutants tend to linger closer to the ground, particularly during periods of low wind speed.

Itāmāti’s air quality experiences a distinct seasonal cycle dictated by the region’s tropical monsoon climate. The monsoon season, typically spanning from June to September, brings heavy rainfall and strong winds, effectively flushing the atmosphere and significantly improving air quality. This period generally offers the most favourable conditions for outdoor activities. Conversely, the pre-monsoon months (March-May) often witness a deterioration in air quality due to rising temperatures and decreasing rainfall. The increased heat promotes the formation of stagnant air masses and temperature inversions, trapping pollutants near the ground. Agricultural burning, a common practice in the surrounding rural areas to clear fields for the next planting season, further contributes to particulate matter pollution during this period. The post-monsoon season (October-November) is characterized by a gradual decrease in rainfall and a return to calmer winds, which can lead to a slight increase in pollutant concentrations compared to the monsoon months, though generally not as severe as the pre-monsoon peak. Winter months (December-February) are typically cooler with periods of dense fog, which can significantly reduce visibility and trap pollutants, particularly particulate matter. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the pre-monsoon and winter months, limiting prolonged outdoor exposure and considering the use of air filtration devices. The interplay of wind patterns, temperature fluctuations, and agricultural practices shapes the air quality narrative in Itāmāti throughout the year.
