INDOOR DEATH POLLUTION

DEATH POLLUTION




 OVERVIEW

Indoor air pollution is dust, dirt, or gases in the air inside buildings such as your home or workplace that could be harmful to breathe in. Poor indoor air quality has been linked to lung diseases like asthma, COPD and lung cancer. It has also been linked to increased risk of heart disease and stroke .

DESCRIPTION OF HOUSEHOLD AIR POLLUTION

Household air pollution is a leading cause of disability-adjusted life years in India and the third leading cause of disability-adjusted life years globally. There are at least sixty sources of household air pollution, and these vary from country to country. Indoor tobacco smoking, construction material used in building houses, fuel used for cooking, heating and lighting, use of incense and various forms of mosquito repellents, use of pesticides and chemicals used for cleaning at home, and use of artificial fragrances are some of the various sources that contribute to household air pollution.

Household air pollution affects all stages of life with multi-systemic health effects, and its effects are evident right from pre-conception to old age. In utero exposure to household air pollutants has been shown to have health effects which resonate over the entire lifetime. Exposures to indoor air pollutants in early childhood also tend to have repercussions throughout life. The respiratory system bears the maximum brunt, but effects on the cardiovascular system, endocrine system, and nervous system are largely underplayed. Household air pollutants have also been implicated in the development of various types of cancers.

Identifying household air pollutants and their health implications helps us prepare for various health-related issues. However, the real challenge is adopting changes to reduce the health effects of household air pollution and designing innovative interventions to minimize the risk of further exposure.

SOURCES OF INDOOR POLLUTION

Indoor pollution sources that release gases or particles into the air are the primary cause of indoor air quality problems. Inadequate ventilation can increase indoor pollutant levels by not bringing in enough outdoor air to dilute emissions from indoor sources and by not carrying indoor air pollutants out of the area. High temperature and humidity levels can also increase concentrations of some pollutants.

Pollutant Sources

There are many sources of indoor air pollution. These can include:

  • Fuel-burning combustion appliances
  • Tobacco products
  • Building materials and furnishings as diverse as:
    • Deteriorated asbestos-containing insulation
    • Newly installed flooring, upholstery or carpet
    • Cabinetry or furniture made of certain pressed wood products
  • Products for household cleaning and maintenance, personal care, or hobbies
  • Central heating and cooling systems and humidification devices
  • Excess moisture
  • Outdoor sources such as:
    • Radon
    • Pesticides
    • Outdoor air pollution.

EFFECTS OF INDOOR POOR AIR QUALITY 

IMMEDIATE RESULTS 

Some health effects may show up shortly after a single exposure or repeated exposures to a pollutant. These include irritation of the eyes, nose, and throat, headaches, dizziness, and fatigue. Such immediate effects are usually short-term and treatable. Sometimes the treatment is simply eliminating the person's exposure to the source of the pollution, if it can be identified. Soon after exposure to some indoor air pollutants, symptoms of some diseases such as asthma may show up, be aggravated or worsened.

LONG - TERM RESULTS 

Other health effects may show up either years after exposure has occurred or only after long or repeated periods of exposure. These effects, which include some respiratory diseases, heart disease and cancer, can be severely debilitating or fatal. It is prudent to try to improve the indoor air quality in your home even if symptoms are not noticeable.

  Call us for Natural Demo  Air Purification                               Tradescantia pallida Tradescantia pallida  is an  evergreen   perennial plant  of scrambling stature. It is distinguished by elongated, pointed  leaves  - themselves glaucous green, sometimes fringed with red or purple - and bearing small, sterile three-petaled  flowers  of white, pink or purple. Plants are top-killed by moderate frosts, but will often sprout back from roots. The cultivar  T. pallida  'Purpurea' has purple leaves and pink flowers Studies •  Anthocyanins Pigments / Food Colorant : T pallida contained two major anthocyanins. The pigments may have potential as food colorants.   •  Phytoremediation / Indoor Air-Purifying Plant : VOQs (volatile organic compounds including benzene, xylene, hexane, heptane, octane, decane, trichlorethylene (TCE) and methyl...

It is known by the  common names   bird's-nest fern. Asplenium nidus  forms large simple  fronds  visually similar to  banana  leaves, with the fronds growing to 50–150 centimetres (20–59 in) long and 10–20 centimetres (3.9–7.9 in) broad. They are light green, often crinkled, with a black midrib, and exhibit  circinate vernation .  Spores  develop in  sori  on the underside of the fronds....

Call us for Natural Demo  Air Purification                          Thunbergia grandiflora Thunbergia grandiflora  is a long-lived ( perennial ), vigorous,  climbing  plant that can grow up to 15 m in height when supported by a  host   tree . Younger stems are green, hairy ( pubescent ), and square in cross-section ( quadrangular ). The older  climbing  stems are quite thick when mature, and they usually turn brown in colour and become somewhat rounded in shape. The  oppositely arranged  leaves are borne on hairy stalks ( pubescent   petioles ) 4-12 cm long. These leaves are variable in shape (8-22 cm long and 3-15 cm wide) and may have broad heart-shaped ( cordate ) bases, be somewhat  triangular  in shape, or be roughly egg-shaped in outline with broad end at base ( ovate ). Their margins are also quite variable, and can range from being almost entire, to b...
