The Harmful Effects of Photochemical Smog: A Personal Account from Pasadena, CA (1970)
The term photochemical smog is a scientific description of a phenomenon that has left a lasting impact on urban air quality. My personal experience in Pasadena, California, in 1970, provides a vivid account of the harmful effects of this issue that peaked on the 15th of August 2020. This article delves into the impacts of photochemical smog, exploring the health advisories and the toll it takes on daily life.
What is Photochemical Smog?
Photochemical smog is a complex mixture of airborne pollutants that form when pollutants from industrial activities, vehicles, and other sources react in the presence of sunlight. Composed primarily of ground-level ozone, nitrogen dioxide, and peroxyacyl nitrates (PANs), photochemical smog is notorious for its adverse effects on health and the environment. The formation of these pollutants requires sunlight, making it more pronounced during the summer months.
My Personal Experience in Pasadena, CA, 1970
Living in Pasadena, CA, in the early 1970s, the presence of photochemical smog was a daily reality. The impact was felt most intensely around mid-August, a period when the smog levels reached their peak. My experience with this phenomenon was both painful and frustrating. Every day, I found breathing to be an effort, often leading to shortness of breath and a persistent cough. The smog was so dense that it not only made breathing difficult but also irritated my eyes, causing a burning sensation that was uncomfortable and, at times, debilitating. This haze dried out my nasal passages, leaving me with a constant feeling of dryness and discomfort.
The impact of photochemical smog extended beyond personal comfort, affecting the longevity and condition of my car tires. Driving through the smog-laden air accelerated the degradation of rubber, leading to rapid wear and tear on my tires. This meant that I had to replace my tires more frequently, a costly and frustrating experience. The combination of these factors made living in Pasadena during that period less than ideal, and the advice to stay indoors and avoid unnecessary outdoor activities during smog advisories was often taken seriously.
Harmful Effects on Air Quality
The situation in Pasadena, CA, during the 1970s was a stark reminder of the dangers posed by poor air quality. Photochemical smog can significantly lower air quality, leading to a range of health issues. Individuals with respiratory problems, such as asthma, are particularly vulnerable. The air quality health advisory issued for Long Island in 2021 (Saturday and Sunday) serves as a modern cautionary tale, highlighting the ongoing relevance of this issue. Such advisories are issued to protect public health, especially for those with pre-existing respiratory conditions, warning them to stay indoors and limit outdoor activities.
The same applies to those sensitive to air pollution, including individuals with allergies, cardiovascular diseases, and children and the elderly. Photochemical smog can exacerbate these conditions, leading to severe health complications if left unchecked. The long-term effects of prolonged exposure to photochemical smog are of particular concern, as they can contribute to chronic health issues such as lung cancer, heart disease, and asthma.
Measures to Combat Photochemical Smog
Efforts to combat photochemical smog are crucial in improving air quality and protecting public health. Strategies include reducing emissions from vehicles, promoting cleaner energy sources, and increasing public awareness about the importance of reducing pollution. The California Air Resources Board (CARB) has played a significant role in regulating and monitoring air quality in the state. Their efforts have been instrumental in implementing regulations that have led to a reduction in smog levels over the years.
Individual actions also play a vital role. Simple steps such as carpooling, using public transportation, and opting for low-emission vehicles can help reduce the amount of pollutants released into the air. Additionally, supporting policies that promote clean energy and sustainable practices can collectively contribute to a healthier environment.
Conclusion
Living through the peak of photochemical smog in Pasadena, CA, in the 1970s was a challenging experience. The health advisories and the visible effects on daily life serve as a stark reminder of the detrimental impacts of this type of air pollution. While progress has been made in regulating and reducing emissions, the ongoing threat of photochemical smog underscores the need for continued efforts in air quality management. By understanding the harmful effects of photochemical smog and taking proactive measures, we can work towards a cleaner and healthier environment for future generations.
