In a bid to combat the dire environmental situation in the province, the Punjab government has declared a smog emergency in Lahore, Gujranwala, and Hafizabad. The devastating health effects of long-term smog exposure have prompted this decisive action.
Air Pollution’s Severe Impact on Health
Air pollution, particularly smog, has a severe impact on public health. Shockingly, one-third of deaths from conditions like stroke, lung cancer, and heart disease can be attributed to air pollution. This impact is equivalent to that of smoking tobacco and far surpasses the effects of excessive salt consumption.
Understanding Smog
Smog, a visible manifestation of air pollution, primarily plagues urban areas where air pollution levels are alarmingly high. Factors such as high population density, increased transportation, the presence of polluting factories, and industrial facilities contribute to the formation of smog.
Smog is created by the excessive emissions of primary pollutants like volatile organic compounds (VOCs), hydrocarbons, SO2, NO, and NO2. These pollutants react in the atmosphere, giving rise to toxic and carcinogenic secondary smog components. Smog not only reduces visibility on roads but also leads to road accidents and flight cancellations.
Smog’s Devastating Impact on Human Health
The impact of smog on overall health varies depending on various factors. Vulnerable populations, such as seniors and children, are more severely affected. Smog exposure can exacerbate respiratory illnesses, with asthma being a primary concern. Pregnant women and their fetuses are at particular risk, as exposure to air pollution can lead to negative outcomes, including miscarriages and a potential link to autism spectrum disorders.
Respiratory System Vulnerability
Respiratory diseases like asthma, chronic obstructive pulmonary disease (COPD), and certain types of cancer have a clear connection to smog exposure. Smog can worsen existing symptoms or even trigger these conditions. Its impact on the body can be likened to passive smoking, with similar health implications.
Impact on Other Organs
Smog poses a danger to other organs as well. Inhaling smog can lead to the intake of particulate matter so tiny that it can enter the bloodstream through the lungs, affecting various organs. The circulatory system is particularly vulnerable, raising blood pressure and interfering with heart rate. These effects increase the risk of cardiac arrest and strokes.
Protecting Yourself from Smog
To safeguard your health during smoggy conditions, adopting protective measures is essential. Wearing anti-smog masks is one effective way to reduce exposure and protect your well-being.
