Health Risks Associated With Cooking Using Coal

Cooking with coal releases a variety of pollutants that can have significant adverse effects on human health. The combustion process emits particulate matter (PM), carbon monoxide (CO), sulfur dioxide (SO₂), nitrogen oxides (NOₓ), and volatile organic compounds (VOCs). These pollutants contribute to indoor air pollution, especially in poorly ventilated cooking environments.

Particulate matter, particularly fine particles known as PM2.5, can penetrate deep into the lungs and even enter the bloodstream. Chronic exposure to PM2.5 is linked to respiratory diseases such as chronic obstructive pulmonary disease (COPD), asthma, and lung cancer. Carbon monoxide is a colorless, odorless gas that interferes with oxygen transport in the body, posing acute risks such as headaches, dizziness, and in extreme cases, fatal poisoning.

Additional health risks include:

  • Respiratory infections: Increased incidence of pneumonia and bronchitis, especially in children and elderly individuals.
  • Cardiovascular problems: Pollutants can exacerbate heart disease by promoting inflammation and oxidative stress.
  • Eye irritation: Smoke from coal combustion causes irritation and may lead to chronic eye conditions.
  • Cancer risk: Prolonged exposure to polycyclic aromatic hydrocarbons (PAHs) produced during coal burning is associated with elevated cancer risk.

Environmental Impact of Coal Cooking

Using coal for cooking not only affects human health but also contributes to environmental degradation. The emission of greenhouse gases such as carbon dioxide (CO₂) and methane (CH₄) during coal combustion contributes to climate change. Additionally, coal burning releases sulfur and nitrogen compounds that can cause acid rain, damaging ecosystems and infrastructure.

Indoor air quality deteriorates significantly when coal is burned inside enclosed spaces without adequate ventilation. This can lead to long-term environmental health problems for communities reliant on coal for cooking.

Key environmental consequences include:

  • Deforestation: Coal mining and collection often lead to deforestation and habitat loss.
  • Soil and water contamination: Coal ash and residue can leach toxic heavy metals, contaminating local soil and water supplies.
  • Contribution to smog: Emissions of NOₓ and VOCs contribute to ground-level ozone formation, exacerbating smog conditions.
