Pollutants may be the Root Cause of Various Health Problems : A Part from the Book Chapter : A Review of Air Purification by Indoor and Outdoor Plants

Major pollutants like carbon monoxide, sourced from fuel and tobacco combustion, impair oxygen transport in the body, leading to headaches, fatigue, and reduced reflexes. Volatile and semi-volatile organic compounds, emitted from various sources including cooking fumes and cosmetics, have carcinogenic effects. Encountering various chemical and biological pollutants may be the root cause of various health problems. Air pollution remedies include the use of filters like High-Efficiency Particulate Air Filters (HEPA filters), activated charcoal, carbon filters, mopping, ventilation, salt lamps, beeswax candles, etc. The air circulation can be maintained properly by opening doors and windows. As a result, exhausts polluted air goes outside and thereby improves the indoor air quality. The activated carbon filters in the air filter purify the air passing through it. All these are natural, low cost, and quite effective and eco-friendly methods to prevent air pollution.

Recent Global Research Developments in Health Impacts and Remedies for Indoor Air Pollution

Health Consequences of Indoor Air Pollution:

  • Indoor air pollution arises from various sources, including secondhand smoke, carbon monoxide, household air pollution, radon, volatile compounds, semi-volatile compounds, bioaerosols, and respiratory infections.
  • Specific clinical entities related to these exposures include conditions like hypersensitivity pneumonitis and multiple chemical sensitivity.
  • Researchers have linked injury processes (such as inflammation and carcinogenesis) to indoor air pollution exposure [1].

Children’s Health and Well-being:

  • Poor ventilation, climatic conditions, chemical substances, and socio-economic status contribute to indoor air pollution.
  • Preventive strategies are essential to reduce pollution and protect children’s health [2].

Control Strategies and IAQ Improvement:

  • Understanding major indoor air pollution sources and implementing effective control strategies is crucial.
  • Recent trends focus on reducing pollutant concentrations and improving indoor air quality (IAQ) [3].

Cardiovascular Disease and Indoor Pollution:

  • Household air pollution (e.g., from burning kerosene and diesel) contributes significantly to cardiovascular disease.
  • In 2012, it was estimated that 4.3 million deaths (7.7% of global mortality) were attributable to household air pollution [4].
