Know About Common Indoor Air Pollutants
Indoor air pollution is the concentration inside a building or structure of harmful airborne contaminants, often to hazardous levels. It is often caused inside the home by insufficient ventilation, malfunctioning appliances, and different chemicals. There can be a wide variety of health effects from indoor air contaminants. From headaches and exhaustion, including respiratory conditions such as asthma and others. It can even cause death in the most serious cases.Do you want to learn more? check it out
Popular air pollutants in indoor environments:
Radon – a by-product of decomposing radium that is found under buildings in the soil. Radon gas seeps through walls and foundations through cracks. Among non-smokers, it’s the leading cause of lung cancer.
Carbon monoxide occurs from fuel-burning appliances that are not properly designed and ventilated, such as gas stoves and water-heaters. This gas interferes with oxygen supply all over the body.
Dusts and Molds – an excess of build-up of dust or mould is typically due to poor ventilation. These types of particles can cause wheezing and shortness of breath, and contribute to the epidemic of asthma, as well as pulmonary disease.
Compounds used in household cleaners, pesticides, paints/lacquers/varnishes, machines, and construction materials that evaporate into the air are volatile organic compounds. This can trigger negative reactions and affect the central nervous system.
The Global Indoor Emissions Scale
The human health effect is staggering on a worldwide basis. Nearly 2 million people die every year from an infection directly related to their indoor climate, according to the World Health Organisation. Half of the deaths associated with pneumonia in young children was due to the inhalation of particulate matter contained indoors.
For individuals living in the poorest developed countries of the world, the health effects of indoor air pollution are greater. Around 3 billion people worldwide are estimated to still use open sources of fuel or to burn biomass to cook and heat their homes. The concentration of harmful particles can be 100 times greater in their homes than the criteria defined for clean air.
