Everything You Need To Know About Particulate Matter


Delhi has started with the second edition of its previously much-talked about Odd Even rule. The Odd-Even rule was implemented after the air in the national capital became too dangerous to breath in. All the media houses shouted few words all the time : “high PM levels; PM 10 and PM 2.5 levels cross the safe limit; air in Delhi too harmful”.

So how exactly does the PM levels harm our body? Infact, lets start with what exactly is PM?

Particulate matter (or PM) is the term used for a mixture of solid particles and liquid droplets found in the air. Some particles, such as dust, dirt, soot, or smoke, are large or dark enough to be seen with the naked eye.

What is PM 10 and PM 2.5?

PM 10 is particulate matter 10 micrometers or less in diameter, PM  2.5 is particulate matter 2.5 micrometers or less in diameter. PM2.5 is generally described as fine particles. By way of comparison, a human hair is about 100 micrometers, so roughly 40 fine particles could be placed on its width

Fine particulate matter (PM2.5) is an air pollutant that is a concern for people’s health when levels in air are high. PM2.5 are tiny particles in the air that reduce visibility and cause the air to appear hazy when levels are elevated. Outdoor PM2.5 levels are most likely to be elevated on days with little or no wind or air mixing. The New York State Departments of Health (DOH) and Environmental Conservation (DEC) alert the public by issuing a PM2.5 Health Advisory when PM2.5 concentrations in outdoor air are expected to be unhealthy for sensitive groups.

So where does the fine particulate matter come from?

There are outdoor and indoor sources of fine particles. Outside, fine particles primarily come from car, truck, bus and off-road vehicle (e.g., construction equipment, snowmobile, locomotive) exhausts, other operations that involve the burning of fuels such as wood, heating oil or coal and natural sources such as forest and grass fires. Fine particles also form from the reaction of gases or droplets in the atmosphere from sources such as power plants. These chemical reactions can occur miles from the original source of the emissions. PM2.5 is also produced by common indoor activities. Some indoor sources of fine particles are tobacco smoke, cooking (e.g., frying, sautéing, and broiling), burning candles or oil lamps, and operating fireplaces and fuel-burning space heaters (e.g., kerosene heaters).

What are the health effects?

  • premature death in people with heart or lung disease,
  • nonfatal heart attacks,
  • irregular heartbeat,
  • aggravated asthma,
  • decreased lung function, and
  • increased respiratory symptoms, such as irritation of the airways, coughing or difficulty breathing.

Apart from health effects, presence of PM also affects the visibility around. It produces haze, which creates problems for people behind the wheels.

Newsletter Coming out!

We started a social campaign, and now we see ourselves growing! Started from a wordpress blog, we are now moving to our very own Newsletter!


Hello food lovers across the country!
Excited to inform you that we, FICCI Research and Analysis Centre have taken up a social awareness campaign.
We aim to educate all consumers about food quality. We have seen that brands as big as the 2-minute noodles can make a blunder. So what is the surety about other products?
FRAC is a food/beverage/animal feed testing and environmental monitoring laboratory.
We want all consumers to be aware of the industry and demand only safe and quality assured products.
With this in mind, we had launched our blog site Food Quotient some time back:
fraclabs.wordpress.com
which has started growing. We shared news items across different channels, provide life hacks, video tips, information about the industry.
Seeing its success, we are now heading on to our own Newsletter! We invite everyone to be a part of this campaign. You could drop in your email IDs to subscribe. Request you to visit our blogs, share the ones you like the most! And if you like things under 140 characters, we are there on twitter as well: @FRAC_labs  (www.twitter.com/FRAC_labs)

Hope to gather your support!

Watch: Global Warming – Still Believe its a myth?


Hundreds of summits, thousands of protests all around the globe, world leaders coming together to discuss one thing – Global Warming. And yet, quite a lot believe it is all just a myth. Most industrialists do not accept what is proven by Science. The ignorance might be a mask of concern about losses in business. But this video below has been recorded as the biggest caving yet – Greenland is melting!

Request you to watch it, share it, and most importantly ACT upon it. Fossil fuels are not going to last forever. Protect environment!

This rare footage has gone on record as the largest glacier calving event ever captured on film, by the 2016 Guiness Book of World Records.

On May 28, 2008, Adam LeWinter and Director Jeff Orlowski filmed a historic breakup at the Ilulissat Glacier in Western Greenland. The calving event lasted for 75 minutes and the glacier retreated a full mile across a calving face three miles wide. The height of the ice is about 3,000 feet, 300-400 feet above water and the rest below water.

Footage produced by James Balog (http://jamesbalog.com) and the Extreme Ice Survey (http://extremeicesurvey.org)

Chasing Ice won the award for Excellence in Cinematography at the 2012 Sundance Film Festival and a 2013 Emmy Award for Outstanding Nature Programming. It has won over 40 awards at festivals worldwide, and was also nominated for an Academy Award for Best Original Song, “Before My Time” by J. Ralph featuring Scarlett Johansson and Joshua Bell.

Anti-Dengue Fogging is a False Sense of Security ; Ineffective Measure for 25 Years


A Delhi based green NGO, Centre for Science and Environment (CSE) has recently urged the government to focus on more effective measures for combating the largely spread Dengue, as the current measures of Fogging have been ineffective.

According to the NGO, the Anti-Dengue Fogging drives are nothing but a false sense of security among the public, a measure that is used by the Government’s for appeasement by wasting lakhs of litres of Diesel every year. CSE urged the government to focus on systematic preventive measures towards clean environment and sanitation. Its assessment said that 4.5 lakh litre of diesel could be used this year for fogging, which comes to 4,500 litres of diesel per day and is also equivalent to the usage of diesel by 2,000 cars in a day. CSE said that targeting adult mosquitoes offers temporary control and that too in limited settings and under ideal conditions and unless repeated frequently, fogging cannot control the next batch of adults out of the larvae. Thus, a source control is a must, using larvacides, to destroy the larva, and effectively prevent public from Dengue. The WHO guidelines on dengue too “questions” the role of fogging and recognises that fogging has been used by South-East Asian countries for the past 25 years but has not been effective.

“Medical experts suggest that direct inhalation of diesel fumes, combined with insecticides, can exacerbate asthma or bronchitis among those with respiratory ailments.

“Pregnant women, small children and old people are most susceptible to aggravation. Eye specialists also mention that diesel fumes can also cause irritation and itching on skin and eyes. Prolonged exposure could lead to temporary swelling of the corneas,” CSE said.
