Flashback to February 18
American History

The tragic event that took place in Donora, Pennsylvania, USA on October 30, 1948 remains a significant point of reflection in history. This incident, which involved 20 deaths and close to 6,000 people falling ill due to smog, dramatically brought visibility to the terrible consequences of unchecked industrial pollution.
The day started like any other, but with a heavy and thick smog hanging over the town. Little did the residents of Donora, Pennsylvania know, they were in the throes of a deadly smog event. For days, the smog, a thick fog tarnished with industrial pollutants, remained stagnant over Donora, a small town known for its steel mills and a zinc smelter. As the days passed, the smog became denser, turning day into night, and triggering an invisible public health crisis.
Details of the ordeal relayed by survivors and records of the time frame portray a grim scene. Visibility was less than a few feet, streetlights stayed on throughout the day, and indoor lights barely pierced the gloom. On the fateful day of October 30, after five days of enduring the choking smog, the town of Donora witnessed the demise of 20 of its residents. Shockingly, another 6,000 fell severely ill, a consequence of prolonged exposure to the smog. By the time the smog lifted, over half of the small town had felt its lethal blow.
When we dive into the causes, it is impossible to disregard the role of industrial pollution. Several investigations traced the deadly smog back to pollutants released from the nearby Donora Zinc Works. The smog had high concentrations of sulfur dioxide, soluble sulphates, and heavy dust, believed to be released by the smelting process. Combining these factors with unusual weather conditions, a deadly mix was formed. This resulted in the severe health crisis that showed how business interests could overtake public health.
Chronicling the reaction from the public and government authorities, it was clear that change was imperative. The event in Donora, Pennsylvania prompted nationwide introspection on air pollution, industrial processes, and environmental safety. There was a dynamic shift in public consciousness towards the environment and the value of fresh, clean air.
In response to the tragic event, changes were implemented to safeguard air quality and public health. Enactment of the Clean Air Act in 1955, followed by revisions in 1963, 1970, 1977, and, finally, 1990, showed nationwide progress towards stronger air pollution control measures. These revisions aimed to control and decrease the amount of pollutants released into the atmosphere. The Donora Smog event of 1948 acted as a catalyst, emphasizing the dire need for these improvements.
Several decades down the line, the event offers an essential reminder of the severe consequences of unchecked environmental pollution. Donora, Pennsylvania serves as an emblem of the adverse effects of industrial pollution on air quality and public health.
In a bid to preserve and learn from this, The Donora Smog Museum was established in the town. This museum serves as a stark reminder of the 1948 disaster and the need for constant vigilance and proactive policies to protect air quality.
