Clean air is no longer available if you are in India

Air Pollution in Indian cities
Based on data published on the World Air Quality Index website, Faridabad, Lucknow, Muzaffarpur, Agra, Pune and Rohtak too fall in the hazardous range.

It’s not Delhi alone struggling with air pollution.  Based on data published on the World Air Quality Index website, Faridabad, Lucknow, Muzaffarpur, Agra, Pune and Rohtak  too fall in the hazardous range. All these cities have an air quality index of greater than 300. The Air Quality Index is calculated based on PM2.5, PM10, Ozone, NO2, SO2 and CO levels as hourly measurements. This is a continuous monitoring system and values will vary on an hourly basis and in India they collect data from 62 centers. The surprising fact is that out of this 62 centers, Haldia in West Bengal and Saneguruvanahalli in Bangalore alone has good air quality index. Remaining all cities fall within moderate to very unhealthy range.

Indeed scary. You can check data for yourself here.

The Villains in Air

If Urban air pollution is the contribution of combustion of fossil fuels, In rural areas Household air pollution (HAP), is a serious area of concern. The main villains are particulate matter (PM), measured as particles which have an aerodynamic diameter lesser than 10 μm (PM10) and lesser than 2.5 μm (PM2.5), nitrogen dioxide, sulfur dioxide and ozone. It’s not that others are not harmful, mostly these four are measured as in indicator to determine air quality. The WHO guideline values for particulate matter are 20 μg/m3 for PM10, 10 μg/m3 for PM2.5, 40 μg/m3 for NO2 and 20 μg/m3 for SO2.

Air Pollution Facts at quick glance:

  • India has higher air pollution levels than China
  • As per Greenpeace Report, 1.2 million deaths take place every year due to air pollution in India
  • First place goes to Delhi, Faridabad, Lucknow, Muzaffarpur, Agra, Pune and Rohtak

Air Pollutants and Health Impact

Nitrogen dioxide

NO2 is increasing at an alarming rate in Indian cities, thanks to increase in number of vehicles. NO2 is extremely detrimental to lungs. Exposure to NO2 over a period of one to three years increases incidence of bronchitis, emphysema and also adversely affects lung performance. Exposure to excessive NO2  affects the defense mechanism too.

Carbon Monoxide

80-90% of absorbed CO binds with Haemglobin and from Carboxyhaemoglobin. The scary fact is affinity with CO binds to Haemglobin is 200-250 times more strongly than that with oxygen. The symptoms of CO poisoning may include headache, dizziness, drowsiness, and nausea. At next stage  vomiting and  loss of consciousness is observed.  If prolonged exposure continues, it may lead to coma or even death.

PM2.5

Though  PM2.5 is too small in size, it can cause an array of health problems, including premature mortality, chronic respiratory disease,  asthma and decrease in lung function. Another critical point is that, it contains large proportion of metals and acids, and also it can penetrate into the respiratory tract deeper because of its size.

Ozone

Exposure to Ozone again can lead to  bronchitis, emphysema and also adversely affects lung performance. The impact of ozone is all the more high on sunny days. Children are at high risk as their lungs are still developing. Also people with reduced intake of  nutrients like vitamins C and E, are at greater risk from ozone exposure.

SO2

SO2 is hygroscopic in nature. SO2 reacts with humidity and forms sulphuric and sulphurous aerosol acid. These acids are extremely hazardous as these compounds enter the circulatory system directly through the airways. SO2 can also irritate the skin and mucous membranes of the eyes, nose, throat, and lungs.

Ways to Purify Air at Home

Get your Air Purifier

Market is crowded with Air purifiers. From Philips to Kent, everyone has come to market with new air purifiers. But before you go ahead and buy one for your home, just understand the technology that drives the purifier. One could find four types of air purifiers

  • HEPA Technology : HEPA filters can trap 99.97% of all particles larger than 0.3 microns
  • Activated Carbon Technology: Very effective method to capture pollutants such as chemical emissions, gases, tobacco, odors and smoke
  • UV Technology: UV technology based purifier is effective in killing viruses and bacteria. Mostly these purifies will have a layer of HEPA filter too
  • Negative Ion: To clean the air, negative ion air purifiers use chemical injections

Go natural

Air Purifier

Air Purifier: Spathiphyllum

Beeswax candles or Honey candles

Replace regular candles with Pure Beeswax Candles.  These candles burns with almost no smoke or scent and clean the air by releasing negative ions into the air. These ions binds to toxins and remove them from the air.

Salt lamps

Use salt lamps made from Himalayan crystal salt. Negative ions released from them binds to toxins and remove them. One can leave the lamp on at night as well, since the natural orange glow won’t disrupt sleep hormones. They can work even if they are turned off .

Houseplants are the best

Houseplants can freshen the air within houses and workplaces, without any side effects. The best plants to filter toxins from the air are Peace Lily, Lady Palm, Aloevera or Broadleaf Lady Palm.

Air Pollution is going to stay for ever. No one can reverse to good old days with clean air. Just that one need to decide on ways to protect from this danger.
