Balyqshy, situated in the Atyraū Province of Kazakhstan at coordinates 47.0667° N, 51.8667° E, is a city intrinsically linked to the Caspian Sea. Located approximately 120km east of the Caspian coastline, its geography is defined by the vast, flat expanse of the West Kazakhstan Plain. The terrain is largely semi-desert and steppe, with a gradual elevation increase moving inland. This flatness contributes to limited natural air dispersion. Balyqshy’s development is heavily influenced by its proximity to the Tengiz oil field, one of the world’s largest, creating a significant industrial belt to the northeast. The city serves as a logistical and residential hub for workers in the oil industry. Surrounding Balyqshy are expanses of pastureland, used for livestock grazing, and agricultural areas focused on grain production. The urban-rural gradient is relatively sharp; the city itself is compact, quickly transitioning to open steppe. This proximity to both heavy industry and agricultural practices, combined with the prevailing wind patterns across the flat landscape, significantly impacts local air quality. Dust storms, common in the region, exacerbate particulate matter concentrations, while industrial emissions contribute to other pollutants. The Caspian Sea, while a source of moisture, doesn’t provide substantial wind-driven dispersion due to the distance and prevailing wind directions.

Air quality in Balyqshy experiences distinct seasonal variations. Spring (March-May) often sees a surge in particulate matter due to dust storms originating from the surrounding dried-out lakebeds and agricultural lands as the ground thaws. Winds pick up, carrying these particles into the city. Summer (June-August) typically offers a temporary respite, with occasional rainfall helping to suppress dust, but higher temperatures can promote the formation of ground-level ozone from industrial emissions. Autumn (September-November) is often the most challenging period. Temperature inversions become frequent, trapping pollutants near the ground, and the burning of agricultural residue after harvest adds to particulate matter levels. This period sees the highest concentration of pollutants. Winter (December-February) brings cold, stable air masses, exacerbating the effects of inversions and trapping emissions from heating sources – both residential and industrial. Sensitive groups, including children, the elderly, and those with respiratory conditions, should limit outdoor activity during autumn and winter. Months to avoid prolonged outdoor exposure are October and November. Spring can be problematic too, particularly during windy periods. Staying indoors on high-pollution days and using air purifiers are recommended.
