Çayırova, situated within Kocaeli Province in Turkey, occupies a strategically important, yet geographically complex, position. Located at coordinates 40.8000, 29.4167, the city is part of the Marmara Region, a densely populated area bordering the Sea of Marmara. The terrain is characterised by a mix of gently rolling hills and plains, transitioning towards the more rugged landscapes of the Kartepe mountains to the south. Çayırova’s elevation is relatively low, contributing to potential temperature inversions that trap pollutants. Its proximity to the sea influences local weather patterns, but also exposes it to maritime air masses carrying pollutants from Istanbul and other industrial centres along the coastline. Crucially, Çayırova is a significant industrial hub, hosting numerous manufacturing facilities, particularly in the automotive, chemical, and metalworking sectors. This industrial concentration is a primary driver of local air pollution. The urban-rural gradient is rapidly diminishing as industrial zones expand, encroaching upon previously agricultural land. The surrounding landscape features a blend of farmland, forests, and increasingly, industrial estates. This combination of factors – industrial activity, topography, and proximity to major urban areas – creates a challenging environment for maintaining good air quality in Çayırova.

Çayırova experiences a temperate climate with distinct seasonal variations impacting air quality. Winter (December-February) often sees the poorest air quality due to increased reliance on coal and other solid fuels for heating, coupled with frequent temperature inversions trapping pollutants near the ground. Calm, stable atmospheric conditions exacerbate this, leading to higher concentrations of particulate matter. Spring (March-May) brings some improvement as temperatures rise and rainfall increases, washing away accumulated pollutants. However, agricultural burning in surrounding areas can temporarily degrade air quality. Summer (June-August) generally offers the cleanest air, aided by prevailing winds dispersing pollutants and higher temperatures promoting atmospheric mixing. However, prolonged heatwaves can lead to increased ozone formation. Autumn (September-November) is a transitional period, with decreasing temperatures and increasing heating demand leading to a gradual decline in air quality. Fog, common during autumn mornings, can trap pollutants, reducing visibility and increasing respiratory irritation. Sensitive groups – children, the elderly, and those with pre-existing respiratory conditions – should limit strenuous outdoor activity during winter and autumn months. Monitoring wind direction is crucial; winds from the northwest often carry pollutants from Istanbul.
