A major cause of asthma may be ultrafine particles generated by cooking appliances
Tuesday, March 9, 2010, 04:12 AM

A Hypothesis by Jamson S. Lwebuga-Mukasa, MD, PhD. Founder and Director, Center for Asthma and Environmental Exposure, Lung Biology Research, 100 High Street, Buffalo, NY 14203.
March 9, 2010

This article presents a hypothesis that asthma may be caused by inflammation of air passages by tiny particles with a diameter less than one thousandth the thickness of one’s hair. These ultrafine particles are present in the air we breathe, especially in poorly ventilated kitchens, in work places and near busy roadways.

The particles are produced by cooking and other activities such as smoking. Inhalation of the particles causes intense inflammation of the sinuses and air airways. Repeated inflammation can combine with and intensify allergic reactions and may even promote infection. Recognition of the role of particles in our airway inflammation and asthma opens a new approach to more effective management, and prevention of not only of asthma but also of chronic obstructive pulmonary disease (COPD) and their exacerbations.

We do not know the exact causes of asthma. Read More...

A new fear: third-hand cigarette smoke
Thursday, February 11, 2010, 03:01 PM
Posted by Administrator


A California research lab has found in a recent that third-hand smoke, or the residue of cigarettes that is left on clothing, paper or walls, is extremely carcinogenic when combined with an indoor pollutant.

“The biggest message is the study reveals that the tobacco smoke residue that remains after smoking, sometimes days or weeks later, could pose a risk to people who occupy that space or use it,” said Lara Gundel, the co-principal investigator in a study published in the Proceedings of the National Academy of Sciences.

That risk increases when the residue combines with a common indoor pollutant, nitrous acid, Gundel said. Nitrous acid usually floats inside a building and is generated by unvented gas appliances or diesel engines.

Together the residue and pollutant become potentially even more carcinogenic, forming a tobacco-specific nitrosamine, which is extremely hazardous, the scientist explained. In fact Gundel said when nicotine and nitrous acid combine, Gundel said, they are much more dangerous than just nicotine. Read More...

Traffic fumes increase the risks of child pneumonia
Monday, January 25, 2010, 03:04 AM
Posted by Administrator

Children who live near a main road are in greater danger of catching pneumonia because pollution from passing traffic damages their lungs. A leading expert in childhood breathing difficulties has made the link between exposure to particles from vehicle exhausts and a child's susceptibility to the chest infection, which can be fatal.

Professor Jonathan Grigg, an honorary consultant at the Royal London Hospital and academic paediatrician at Queen Mary, University of London, made the breakthrough after studying the effect of airborne pollutants on human lung cells. Children whose home is within 100 metres of a main road could be as much as 65% more likely than others to develop pneumonia, he said. Read More...

Report Links Vehicle Exhaust to Health Problems
Wednesday, January 13, 2010, 08:13 PM
Posted by Administrator


Exhaust from cars and trucks exacerbates asthma in children and may cause new cases as well as other respiratory illnesses and heart problems resulting in deaths, an independent institute that focuses on vehicle-related air pollution has concluded.

A relationship was found between pollution from vehicles and impaired lung function and accelerated hardening of the arteries.
The report, to be issued on Wednesday by the nonprofit Health Effects Institute, analyzed 700 peer-reviewed studies conducted around the world on varying aspects of motor vehicle emissions and health. It found “evidence of a causal relationship,” but not proof of one, between pollution from vehicles and impaired lung function and accelerated hardening of the arteries. Read More...

Noor Javed

Gone are the chemical-leaking plastic bottles. Ever present are the bacteria-killing wet wipes. New parents, more than anyone, are obsessive about protecting their children.

But what if their immediate environment is what is harming the child?

After years of seeing a dramatic rise in children coming to hospitals with severe allergies and asthma, researchers believe the environment of expectant mothers may be to blame for health problems. They just aren't exactly sure how.

So researchers across the country have launched a study that will document the lives and medical information of 5,000 pregnant women, tracking their genes, nutrition, stress levels, air quality where they live and work, pets and dust in their homes. The women and their families will be questioned for five years or more, once the child is born. Read More...

Sleep Debt and Pure Air's Effect on Sleep/Health Restoration and Disease Prevention
Sunday, January 3, 2010, 07:21 PM
Posted by Administrator
by Wm Holland-Bach

Clean, pure air is the most important tip for healthy sleep,for without it, one's body accumulates sleep debt at an increasing pace. Sleep debt is the effect of not getting enough rest and sleep; a large debt causes mental, emotional, and physical fatigue. It is unclear why a lack of sleep causes irritability, but the very concept of irritants in the body points to the body's ability to cleanse and restore itself during sleep, and to not do so for the lack of it. Our bodies cleanse through a series of sleep hormonal and enzyme occurances that depend upon clean air in our sleeping quarters.

While much attention goes to the types of mattresses and pillows we sleep with, equal or more attention tends to what air cleaning effort or technology we equip our bedroom with. Medical Grade air cleaners have proven most efficient for removal of gases and ultrafine particles that linger in high particle counts in our bedrooms. A six-year study by EnvironmentalExposure.Org showed that patients with asthma, allergies, COPD and other health factors actually improved their health by obtaining consistent sleep with purified air in their bedrooms. Removal of nanoparticles in bedroom air was found by the landmark study to eliminate nighttime exacerbation of inhallation-derived inflammation in respiratory disease and other inflammation-related diseaes.

Tue, Dec 29, 2009

NEW YORK - Air pollution, which tends to inflame the airways in people with asthma, might also reduce the effectiveness of the rescue inhalers they count on for quick relief of their asthma symptoms, study findings hint.

Dr. Fernando Holguin, at the University of Pittsburgh, Pennsylvania, and colleagues studied 85 asthmatic children, ages 7 to 12, to determine whether outdoor air pollution had any impact on how well their rescue inhalers worked.

The children all lived in Mexico City, where traffic-related air pollution is usually very high. Fifty-three of the children had mild intermittent asthma, 20 had mild persistent asthma, and 12 had moderate persistent asthma. Read More...

Exposed to vehicular pollution during a large part of the day, traffic policemen face a high risk of changes in genetic material.

Changes in chromosomes, the carriers of genetic information in a cell, have been associated with the risk of cancer.

The new evidence that air pollution causes damage to chromosomes was found during a study carried out by scientists of the Osmania University in Hyderabad.

The study compared the chromosomal changes in traffic policemen with those among people in other jobs. Read More...

Air pollutants from vehicle exhaust linked to severe pneumonia in seniors
Wednesday, December 23, 2009, 02:34 PM
Posted by Administrator
By: Sheryl Ubelacker, Health Reporter, THE CANADIAN PRESS

TORONTO - Prolonged exposure to high levels of chemicals from motor vehicle exhaust fumes and industrial air pollutants can lead to hospitalization for pneumonia among seniors, a study has found.

The study, led by researchers at McMaster University in Hamilton, set out to assess the effects of long-term exposure to nitrogen dioxide and sulphur dioxide from motor vehicle emissions and fine particulate matter from industrial air pollution.

"We compared people over the age of 65 who were admitted to hospital for community-acquired pneumonia to randomly selected people from the same community who did not have pneumonia," said principal investigator Dr. Mark Loeb, an infectious disease specialist at McMaster.

"And what we found was that individuals who developed community-acquired pneumonia were more likely to have long-term exposure to nitrogen dioxide (from vehicle exhaust) and they were twice more likely to be hospitalized." Read More...

Household Appliances Contributing to Nanoparticles in the Home in Greater Numbers Than Previously Detected
Tuesday, December 22, 2009, 03:29 PM
Posted by Administrator
Extremely small nanoscale particles are released by common kitchen appliances in abundant amounts, greatly outnumbering the previously detected, larger-size nanoparticles emitted by these appliances, according to new findings* by researchers at the National Institute of Standards and Technology (NIST). So-called "ultrafine particles" (UFP) range in size from 2 to 10 nanometers. They are emitted by motor vehicles and a variety of indoor sources and have attracted attention because of increasing evidence that they can cause respiratory and cardiovascular illnesses.

NIST researcher Cynthia Howard Reed and guest researcher Lance Wallace measure nanoparticles emitted by common household appliances. The new experiments can measure 'ultrafine particles' ranging in size from 2 to 10 nanometers. Credit: NIST

NIST researchers conducted a series of 150 experiments using gas and electric stoves and electric toaster ovens to determine their impacts on indoor levels of nano-sized particles. Previous studies have been limited to measuring particles with diameters greater than 10 nm, but new technology used in these experiments allowed researchers to measure down to 2 nm particles—approximately 10 times the size of a large atom.

Impaired cognition in elderly women linked to traffic pollution.
Tuesday, December 22, 2009, 02:24 PM
Posted by Administrator
Editor's Note:

Most people are in traffic for periods of an hour or so. But people who live in buildings next to traffic succumb to its nanoparticle pollution effects 24-7. The following study reports that elderly women who live by or near urban traffic suffer cognitive skill loss linked to the effects of constant traffic pollution. If that is the problem, then the first action toward solution is indoor air cleaning. Studies show that eight hours of nanoparticle-free breathing/sleeping space a night can bolster a person's defenses against indoor pollution's ill effects.
--William Holland Bach, EHN News

Cognitive performance is decreased in elderly women who live near and are exposed to particulate pollution from nearby traffic.

Living for decades near busy urban or rural roads may affect brain health and could contribute to cognitive decline as women age, conclude German scientists in a study published in the journal Environmental Research.

The closer the women lived to the highways, the higher was their exposure to particulate pollution and the more likely they were to show signs of mild memory and cognitive decline. This is the first study to find an association between cognitive impairment and long-term exposure to air pollution due to traffic. It is also one of a handful of recent studies to report a link between air pollution and brain function in people. Read More...

Sharp rise in metals in Mount Everest ice mirrors growth in Central Asia.
Monday, December 21, 2009, 02:30 PM
Posted by Administrator

Ice core samples from Mount Everest that represent 800 years of atmospheric history contain much higher levels of certain metals in the last three decades than in the previous seven centuries. The metals are linked to the rising use of fossil fuels in Asia during that same time period.

Economic growth and more burning of fossil fuels by industries and cars in central Asia since the 1970s has resulted in higher levels of metals deposited in recent layers of ice collected from Mount Everest.

Does traffic pollution cause early pregnancy loss?
Friday, December 18, 2009, 05:43 PM
Posted by Administrator

Traffic and residential health studies are on the increase.

Rates of miscarriage are three times higher for African-American women who live within 50 meters of a busy road than for those who live farther away.

A study from California suggests that living closer to high traffic roads may increase the risk of spontaneous abortion in certain women. The association was seen only with African-Americans, not with women of other races.

Spontaneous abortion – or miscarriages before 20 weeks of gestation – occurs in approximately 10 to 15 percent of pregnancies.

This is the first study to examine the association of living close to high traffic areas with spontaneous abortion. However, exposure to environmental tobacco smoke – which contains many of the same chemicals as automobile exhaust – has been shown to increase the risk of spontaneous abortion.

Nanoparticles damage DNA? But which type?

An ABC-Australia news report falsely implies that all nanoparticles are alike.

A recent story by the ABC-Australia (Australian Broadcasting Corporation) News begins: “Researchers in the United Kingdom have found some nanoparticles – which can be found in common household items – can damage DNA without even penetrating the cells.”
This is certainly an intriguing beginning. And judging from the spate of comments from the scientific community since the study’s release, the reporter was not alone in finding this story interesting.

Study: Airport Noise Increases Risk of Strokes
Wednesday, December 16, 2009, 02:56 PM

By Tristana Moore
TIME/CNN: December 15,2009

(Berlin) Living under a flight path can seriously damage your health. German researchers have discovered that people who are exposed to jet noise have a substantially increased risk of stroke, high blood pressure and heart disease. The findings are bound to provide further ammunition to anti-airport campaigners and make uncomfortable reading for world leaders at this week's climate summit in Copenhagen.

According to the unpublished study, commissioned by Germany's Federal Environment Agency, men who are exposed to jet noise have a 69% higher risk of being hospitalized for cardiovascular disease. Women living under flight paths fare even worse, logging a 93% higher rate of hospitalization with cardiovascular problems, compared with their counterparts in quiet residential areas. The study found that women who are exposed to jet noise (of about 60 decibels) during the day are 172% more likely to suffer a stroke. Read More...

Before Going to Bed, "Brush Your Teeth-- and Wash Your Air"
Sunday, December 13, 2009, 11:35 AM
Posted by Administrator

If we could only see what we're breathing during the night...the truth is, we can "feel" what we've breathed come the following morning. Today let's look at the sleep cycle, and what attends it in terms of air quality.

Ready, set--REV your sleep engines. Or better yet, REM them! (REM is Rapid Eye Movement, an important stage of essential sleep). The two essentials to nutritious, hygenic sleep are clean breathing air, and eight hours’ time to invest per night. Meet these two criteria, and you could sleep on a rock, and wake up refreshed.

Americans are notoriously sleep deprived; we’re up early and rush to work, up late with TV, --our hurried patterns limiting a good full night’s sleep have caused a sleep-pharmaceutical industry to rise in the billions and growing.

An average of eight hours’ sleep each night in a bedroom with clean breathing air is essential to maintain our balance of cognitive skills, such as speech, memory, innovative and flexible thinking. As this article will show, the evolving stages of sleep over the course of the night slow down the heart and breathing capacity, allowing the body’s enzymes to work their night jobs on our daily refreshment cycle.

Even the most visibly clean sleeping quarters has a constant attack of invisible indoor pollutants—dust, dander (both human and pet), airborne organic chemicals, bazillions of dust mites, multiple allergens and microscopic particulates, plus mold spores, household off-gases and more. A good air purifier using ample amounts of real HEPA filter and activated carbon can be the most important element in your bedroom.

When the air in our bedroom isn't its purest, we wake in the morning to itchy eyes, congestion, and restless fatigue, after our bodies are wrought by having worked all night to clean the air we breathe. We actually produce approximately two tablespoons of toxic phlegm, all of which potentially leads to allergies, asthma and other respiratory illness.

If someone tells you they only need a few hours sleep, it’s similar to someone who fills up on only one food category, say hot dogs, missing out on a fuller and healthier nutrition range. Sleep science works much the same way in everyone: it occurs in 90-minute cycles and it is broken into Rapid Eye Movement (REM) and non-REM, which is then broken into four healthy sections.

When we first fall asleep we enter into the first stage of non-REM, light sleep. During this stage our muscle activity slows down and we're half awake and half asleep. We enter stage two after 10 minutes of light sleep. The breathing pattern and heart rate slows. This lasts for around 20 minutes. Stage three and four are deep sleep. This is when our heart rate and breathing are at their lowest levels, when we need toxic-free air the most.

By the time we reach age 50, our lung capacity is about half of what it was when we were 20. Compound this by the fact that when we sleep, horizontally, we operate at about half of our daytime lung capacity, so much more in need of clean, breathable bedroom air.

REM periods occur usually 70 to 90 minutes after we've fallen asleep. Although we are not conscious our brains are very active, even more so than when we're awake. Dreams are most likely to occur during this period. After REM sleep, the whole cycle begins again. Running a HEPA/Carbon air cleaner in the bedroom enfrees the body to evolve into the REM cycles, unhindered by overworking one’s lungs trying to clear the air.

So, before you go to bed-- brush your teeth, and wash your AIR!

One more thing. Talk with your doctor about the air cleaner that is best suited for you, or you can contact our health team at Environmental Health Network for reviews and more information.

"a loud, unending scream piercing nature"
Saturday, December 12, 2009, 02:51 PM
Posted by Administrator

As glaciers melt and the changing temperatures of fjords send fishing communities yonder to respectively warmer or colder parts, it is Norway that seems a fitting place to symbolize and cite much of what is fast changing in our global climate.

Today is the birthday of painter Edvard Munch, born in the village of Ã…dalsbruk, Norway (1863). In many ways this Norwegian's painting The Scream is a bit prophetic, even its title can fit as the prequel to the later Rachel Carlson's Silent Spring.

In 1892, Munch wrote in his journal: "I was walking along the road with two friends. The sun set. I felt a tinge of melancholy. Suddenly the sky became a bloody red. I stopped, leaned against the railing, dead tired, and I looked at the flaming clouds that hung like blood and a sword over the blue-black fjord and the city. My friends walked on. I stood there, trembling with fright. And I felt a loud, unending scream piercing nature."

And the next year, in 1893, Edvard Munch painted the first of several versions of The Scream.

“Allergic to, but still sleeping with your cat? You're not alone.”
Wednesday, December 9, 2009, 06:25 PM
Posted by Administrator

If you are allergic to but still sleeping with your cat, you're not alone. Millions share your dilemma, according to the American Humane Society, who reports that over two million Americans are cat owners who are also severely allergic to their own cats (and who very likely still allow their cats to share their bedrooms). Cat owners-- even allergic cat owners—simply love their cats.

I know. My wife Marie is one of them. And so is our friend Tom who has three cats. Add to the list our other friends Fred and Maggie who have five cats. Gosh, the list goes on-- people who love their cats but are in fact allergic to them. Only two million of them, they say?

Here’s the problem. Cats produce a large amount of free floating hair and dander. The size of the cat dander particles, (those that don’t fuel the dust mite population and its resulting allergens) however, is extremely small, and we inhale these respiratory aggravators deep into our lungs. Therefore, cat owners who are allergic to cats are more prone to the development of asthma and allergy symptoms.

While the problem can be explained scientifically, the solution (getting rid of the cat?) carries an emotional repulsion. So what does one do for a solution? We're on a hunt for answers here at EHN, and we'll get back to our readers. Meanwhile, if you have any suggestions, please feel free to share!

Winter's Indoor Woes-- Think Clean, Think Healthy!
Wednesday, December 9, 2009, 05:38 PM
Posted by Administrator

Holidays also mean adapting into winter's "indoor living" where the air can be far more stagnant and polluted than outdoors, in fact from 5 to 20 to even 100 percent worse, according to the EPA.

Our ongoing focus here at Environmental Health Network is to create healthier indoors for you at home, and at work, and reduce the indoor culprits that cause sickness.

Please use our site as your family's resource for ongoing indoor environmental education.

Did you realize the air we breathe 15,000 to 35,000 times a day provides over 90% of our life energy?

With allergies doubling since the 1970's, and asthma increasing at epidemic proportions, it's no wonder attention has grown between a doctor and patient to see beyond the patient, to the home environment.

Start your family indoor health care plan today. At Environmental Health Network, we'll help you reduce the indoor causes for sickness, reversing these trends through education, a partnership with your family and our team, and the introduction, one peice at a time, of the necessary tools of products, programs and services.

Doctors, Allergists, and health care specialists, in their role as an Environmental Health Network (EHN) Associate, will refer patients and clients to EHN for the following reasons:

• Environmental Health Network looks beyond the patient's symptoms, to their home environment indoor health care needs. Till now, doctors treated symptoms, then returned patients back home, to the scene of the crime.

• Environmental Health Network's website provides credible resources for families and health care professionals, bringing together ongoing education programs as well as healthy home products and services.

• Guidelines for IHCN's programs, products and services are in coordination and support of the US Environmental Protection Agency, Food and Drug Administration, American Lung Association, American Heart Association, American IAQ Council, , National Sleep Foundation, the Indoor Air Quality Association, and Your Family Needs.

Our Mission at Environmental Health Network:

At Environmental Health Network, we assure that healthy science-based environmental intervention programs are practical and affordable for every family, with the help and guidance of their indoor health care professional.

Doctors and health professionals have for too long been treating only the symptoms of what causes up to fifty percent of our illnesses-- the very indoors in which we live!
