Health Effects of Suspended Particulate Matter (SPM)

Interference with Respiratory System:
Suspended particulate matter (SPM) can have detrimental effects on the respiratory system. When inhaled, these particles can penetrate deep into the lungs, causing irritation, inflammation, and potentially leading to respiratory diseases such as asthma, bronchitis, and even lung cancer.

Exacerbation of Cardiovascular Diseases:
Exposure to SPM has also been linked to an increased risk of cardiovascular diseases. Fine particles can enter the bloodstream through the lungs, triggering systemic inflammation and oxidative stress, which can contribute to the development of conditions like heart attacks, strokes, and hypertension.

Aggravation of Existing Health Conditions:
Individuals with pre-existing respiratory or cardiovascular conditions are particularly vulnerable to the adverse effects of SPM. Exposure to high levels of particulate matter can exacerbate symptoms, worsen the conditions, and increase the likelihood of hospitalizations or other serious health outcomes.

Impact on Overall Well-being:
Apart from specific health effects, prolonged exposure to SPM can also have a negative impact on overall well-being. It can lead to fatigue, decreased lung function, and impaired quality of life, affecting daily activities and productivity.
In conclusion, it is essential to address sources of suspended particulate matter and implement measures to reduce exposure in order to protect public health and prevent the associated health effects.

Oxides of Nitrogen can damage the respiratory system and cause irritation in the eyes, along with increasing susceptibility to viral infections like influenza. Prolonged exposure to these pollutants can have detrimental effects on respiratory health.

Oxides of carbon, particularly CO2, play a significant role in the greenhouse effect and can contribute to the production of weak carbonic acid, which adds to acid rain. Understanding the impact of these gases is crucial in addressing issues related to climate change and environmental health.
