👉 The June Fumes refer to a seasonal phenomenon characterized by a distinct set of air pollutants that peak in June, primarily due to increased heating and outdoor activities. During this time, higher temperatures and sunlight lead to the formation of ground-level ozone, a key component of smog, as well as other harmful pollutants like particulate matter and volatile organic compounds. These conditions are exacerbated by the return of warmer weather after spring, which can trap pollutants close to the ground, leading to poor air quality. This period is particularly concerning for urban areas and can have significant health impacts, including respiratory issues and exacerbated asthma symptoms.
