Formaldehyde in Mattresses from China?
Mattress makers get wake-up call
Updated: 2013-04-15 07:17By Chen Xin (China Daily)

Half of the mattresses sold in Beijing are substandard, the city's consumer watchdog said on Sunday.
Of the 50 products tested at the National Center for Quality Supervision and Inspection of Furniture and Indoor Environment, 25 failed for such things as color fading, fabric use, toxic substances and durability.
Samples were taken from 50 manufacturers in Beijing and Tianjin, as well as Hebei, Shandong, Guangdong, Guizhou and Zhejiang provinces. Thirteen were palm fiber mattresses and the others were spring mattresses.
Seven products faded too easily, three used thin fabric, eight had excessive formaldehyde content and 17 were beneath national durability standards of durability, according to the Beijing Consumer Association, which organized the study.
Straw was also used in some products instead of palm fiber.
The color of the exterior fabric will run onto sheets or clothes if the mattress's fading resistance does not meet national standards and the fabric will easily fray if it's durability is substandard, Sun Shudong, a division chief overseeing furniture inspection at the National Center for Quality Supervision and Inspection of Furniture and Indoor Environment, was quoted as saying by China Central Television.
The formaldehyde content in some products was 30 times acceptable levels, according to Liu Hailing, a division chief overseeing indoor environmental inspection at the center.
Under the national standard, formaldehyde emissions from a mattress may not exceed 0.05 milligrams per square meter per hour.
"Inhaling formaldehyde could cause constriction in the chest and coughing, and other respiratory diseases. It could also lead to cancers and leukemia in children if the exposure to the formaldehyde is lengthy," said Zhao Ping, vice-president of the Cancer Foundation of China.
The consumer association said it informed the manufacturers of the substandard mattresses and commerce authorities are investigating.
Qu Shengping, general manager of Beijing Hongdameidi, whose products showed excessive formaldehyde and weak durability in testing, admitted they used cheap glue and fabric to produce mattresses.
Qu said the sample the Beijing Consumer Association tested was from the inventory.
"We received the test results from the association in February, and, actually, we did not put that batch of products on the market," he said.
The test results showed that a product of Beijing Yasili, another furniture producer, was substandard in color fading resistance, fabric used, formaldehyde content and durability.
Chen, general manager of Yasili, said the association had the product tested early this year but it took the sample from the company in June last year.
"In fact, some customers had called us and complained that the mattresses gave off bad odors and we refunded their purchases," he said.
Chen said they recalled those mattresses from dealers at the end of November.
"The mattress makers involved should compensate customers, and commerce authorities should fine them," said Ge Youshan, a lawyer who specializes in consumer rights. "More serious penalties, such as suspending or revoking their business licenses, could be used if producers continue to make substandard goods."

Car Hazardous Pollutants
If you’re like most people, your car is more than just a means of transportation — much, much more. It represents freedom. Your independence to go places, choose your own path and for the adventurous types, discovering the previously unexplored.
For nearly a century the hyper-mobile society we live in has meant we have developed a deep love affair with our automobiles. The social interdependence between human and machine is undeniable, but it goes farther than that.
There’s a psychological dependence too. Modern humans have developed a nearly innate ability to see our vehicles as an extension of ourselves.
Given the sanctity of that relationship, what I’m about to tell you won’t come easy, but you need to know. Our cars are making us — and perhaps worse, our children — sick.
That’s right. Scientific experts have reams of data to show that the nation faces an epidemic of illnesses that are exacerbated by vehicle exhaust. These illnesses include cardiovascular disease, asthma, chronic obstructive pulmonary disease (COPD), lung cancer and diabetes.
The latest study, presented on April 8, 2013 at the American Association for Cancer Research (AACR) 2013 Annual Meeting in Washington, D.C., showed a possible link between exposure to traffic-related air pollution and several childhood cancers.
Julia Heck, an epidemiologist at UCLA’s Fielding School of Public Health and member of Jonsson Comprehensive Cancer Center found that increased exposure to traffic-related air pollution during pregnancy was associated with a higher incidence of acute lymphoblastic leukemia (a white blood cell cancer) and two other rare childhood cancers.
Specifically, Heck found a link to germ cell tumors — cancers of the testicles, ovaries, and other organs — and eye cancer, called retinoblastoma, particularly the type that affects both eyes.
Previous international studies have linked childhood leukemia, lymphomas and brain tumors to vehicle exhaust. The UCLA study is the first to look at vehicle air pollution and rare childhood cancers. The highest increases were found for retinoblastoma and germ cell tumors.
Motor vehicles emit millions of pounds of hazardous pollutants into the air each year in the United States that include compounds such as carbon monoxide, nitrogen oxides, particulates (fine dust and soot), and toxic air pollutants such as benzene.
These chemical particulates have been linked to lung cancer and breast cancer in adults as well as a host of other respiratory and cardiovascular diseases. This was reported in a 65-page policy study by the Connecticut nonprofit, Environment and Human Health, Inc.
The U.S. Environmental Protection Agency (EPA) and the World Health Organization (WHO) estimates that vehicle emissions account for as many as half of all cancers attributed to outdoor air pollution, and account for 1.3 million deaths worldwide each year.
“The main reason for undertaking this study was that we know much more about the causes of adult cancers than we do of the causes of childhood cancers,” said Heck.
“We studied pregnancy exposures because the fetus is likely to be more vulnerable to environmental factors during that time, and we also know that certain childhood cancers originate in utero.”
For the study, Heck and her colleagues identified 3,590 children from the California Cancer Registry born between 1998 and 2007 who could be linked to a California birth certificate and who were five years of age or younger at the time of diagnosis.
Those kids were then compared to 80,224 randomly selected California children in the control group.
UCLA researchers used sophisticated modeling to estimate each child’s exposure to gas and diesel vehicle pollution at home, during each trimester of their mother’s pregnancy with the child and their first year of life. Cancer risk was estimated using a statistical analysis called unconditional logistic regression.
Increases in exposure to traffic-related air pollution positively correlated with increases in childhood acute lymphoblastic leukemia, germ cell tumors and retinoblastoma, according to the study results.
The pollution exposure estimates were highly correlated across pregnancy trimesters and the first year of life, meaning that no particular period stood out as a higher exposure time. This made it difficult for the scientists to determine if one period of exposure was more dangerous than any other, the UCLA study points out.
Because this is the first study of this type, and these are rare diseases, Heck cautioned that the findings still need to be replicated in further studies. Nevertheless, the results provide new leads to potential causes of serious childhood cancers.

What is Sublingual Immunotherapy?
Sublingual immunotherapy, or SLIT, is a form of immunotherapy that involves putting drops of allergen extracts under the tongue. Many people refer to this process as “allergy drops,” and it is an alternative treatment for allergy shots. This form of immunotherapy has been used for years in Europe, and recently has had increased interest in the United States. However, it is not approved by the Food and Drug Administration (FDA) in the United States.
SLIT is usually delivered one of two ways: drops (or tablets) of allergen extract are placed under the tongue, then either swallowed or spat out. Most studies have looked at swallowing the extract, which seems to work better. Immunotherapy by the oral route (swallowed and not kept under the tongue for any period of time), causes too many gastrointestinal side effects (nausea, vomiting, diarrhea), and therefore is not used.
Generally, SLIT is administered daily, or multiple times per week, over a period of years. Most patients are able to self-administer SLIT at home. Studies have looked at giving SLIT before a pollen season, during a pollen season, both, or year-round. It is not yet known what the best dosing regimen is for SLIT.
How Does SLIT Work?
The immune system of the gastrointestinal tract tends to "tolerate" foreign substances, meaning that it does not respond in an over-active way to swallowed material. This makes sense; otherwise the body would over-react to anything swallowed, including food. When SLIT is administered into the gastrointestinal tract, the immune system tolerates the allergen, instead of the over-reactivity of the immune system, as with allergic disease. This results in less allergy symptoms when the body is exposed to the allergy source, such as airborne pollen or pet dander.
How Well Does SLIT Work?
SLIT appears to be effective in the treatment of allergic rhinitis, allergic conjunctivitis and, to a lesser degree, allergic asthma. While most studies on SLIT do show benefit in the treatment of allergic disease, the results are somewhat inconsistent, with up to one-third of studies showing no benefit over placebo treatment.
What is the Safety of SLIT?
Over the past 10 years, the safety of SLIT has been well documented. Serious and fatal reactions to SLIT have not been reported to date. Mild side effects, such as an itchy mouth, occur in the majority of people, and moderate side effects have been documented (1 in about every 12,000 doses), including:
•lip, mouth and tongue irritation
•eye itching, redness and swelling
•nausea, vomiting, abdominal cramping and diarrhea
•sneezing, nasal itching and congestion
•asthma symptoms
•urticaria and angioedema
Because of the safety of SLIT, people generally treat themselves at home, and are followed in the clinic at close intervals to monitor response to treatment.
Who Could (or Should) Receive SLIT?
People with documented allergic disease (allergic rhinitis, allergic conjunctivitis and/or allergic asthma) by allergy testing may be considered for SLIT. Young children have been shown to tolerate and benefit from SLIT, as have older adults. Pregnant women, as is considered the general rule of thumb for allergy shots, can continue SLIT during pregnancy, but should not start the therapy while pregnant. People with severe asthma may need to be monitored more closely on SLIT, since asthma symptoms can worsen with SLIT.
Most studies on SLIT have focused on people with one type of allergy, such as grass or dust mite allergy. People with multiple allergies, such as to molds, pollens, pet dander and dust mite may not be good candidates for SLIT, given the large volume of different allergen extracts that would need to be taken.

Radon
State lawmakers are considering a measure requiring schools to test for radon. But some districts fear that, while it's a good idea, it could be expensive.
Radon is found naturally in Iowa soil, and creeps its way into buildings. At high levels, and with repeated exposure, radon can cause cancer.
That's why state lawmakers may require schools be tested for radon gas.
Whether it's radon testing or other measures, schools everywhere -- including Waverly -- want to keep students safe.
But the big question is: What will it cost?
Jere Vyverberg is on his way out, soon retiring as superintendent of the Waverly-Shell Rock School District. But he's still very concerned about the financial picture at the district next year, since legislators still haven't set school funding.
"That's what we're waiting for," Vyverberg said. "Just how much allowable growth can we expect or can we hope for? ... One is for 2 percent and one is 4 percent -- but that 1 percent can make a whole whale of a difference, especially coming off the hard times and zero allowable growth we've been going through. So we really need to have a good handle on that."
But before those budget decisions are made, the state legislature is voting on other school issues, including education reform and a bill that would require districts to test their buildings for radon.
Vyverberg thinks radon testing could be a good thing. After all, radon is the second-leading cause of lung cancer.
"I can't argue with the validity of doing the testing," Vyverberg said. "Obviously it's something important if it has to do with safety."
But in cash-strapped schools, the question is how to pay for testing -- and, if high radon levels are found, how to fund the pricey systems used to fix the problem.
"I think anything we do for kids is excellent," Vyverberg said. The problem is that when we're coming into hard budget times, like we have right now -- especially with the uncertainty -- we don't know what we can spend money on."
The school testing bill has been approved by the Iowa Senate. It now moves to the House for consideration, and will require the governor's signature before any schools are required to start testing for radon.
U.S. Rep. Bruce Braley is also lobbying for a federal law requiring schools to test for radon. That bill would provide grants to help schools with high radon levels to install mitigation systems, which is a provision the state law does not currently include.

The best ever home cleaning tips!
Your home is your refuge-or is it? Dig a little deeper and you may be surprised at what you find. Here's what to do when you spring clean.
BREATHE EASY
Poor indoor air quality can trigger allergies, irritate your lungs-and even cause cancer. Here, four new ways of improving air quality.
GO GREEN
You know greenery is good for the air; now research reveals that some specific plant species that may rid your home of various toxins. One study found that weeping figs (ficus) efficiently remove formaldehyde gas-released from some carpets and curtains. Other studies have shown that purple ivies eliminate VOCs (volatile organic compounds) like those in paint fumes, Devil's ivy (money plant) removes ozone, a respiratory irritant present in auto emissions (so place where you park your car), and Gerbera reduces levels of benzene, a solvent used for dry cleaning.
home cleaning
DON'T FAKE IT
Phthalates, a class of plasticising chemicals often used in synthetically fragranced products, fuel cancer growth in some of the most hardto-treat types of breast cancer, says a new study published in The Journal of the Federation of American Societies for Experimental Biology. Nix artificially scented toxic air freshener sprays and perfumed candles. Opt for essential oils instead. And if pollen allergy is not a problem for the family, use fresh flowers like tuberose and rose for a natural aroma.
UN-BAG YOUR DRY-CLEANING
The dry-cleaner may have removed the stains from your fave dress, but he's left it covered in toxic chemicals like perchloroethylene or kerosene. These release VOCs linked with kidney and liver damage, nervous system problems-and even cancer. Do not put dry-cleaned clothes in your cupboard right away. Take the plastic bags off and let the clothes air out for a day or two, till the smell is gone
CONSIDER SELF-CLEAN TILES
home cleaning
Imagine ceramics having a positive impact on indoor air quality. So claims the ISO-certified Active Clean Air & Antibacterial Ceramic tile company. The tile they manufacture contains titanium dioxide micrometric particles which help to break down pollutants under the action of light and oxygen. So nitrogen dioxide and VOCs are converted into innocuous compounds which improves the air quality of air you breathe. In fact the University of Milan study claims that 100 square metre of Active tiles reduce toxic nitrogen oxides like 30 trees (22 square metre of leafage) would. The chemical reaction also decomposes harmful bacteria like E. coli, staphylococcus aureus and klebsiella pneumonia. Titanium dioxide also stops dirt and dust from attaching itself to surfaces, making them easier to clean. Try Somany's Dirt Free "Green" tile that has the Active technology.
Secure your home
Do ensure basics like adequate lighting both in and around the house, resilient grills on widows (the kind that cannot be unscrewed), solid doors with hinges on the inside and quality locks. Trim hedges and shrubs so they can't be used as hideouts by intruders. The Crime Investigation Department, West Bengal, advises installing an alarm system especially if you are away from home for long hours. Find out about security solutions that suit your lifestyle from reputed brands like Godrej, Zicom and Eureka Forbes.
Clean with a Conscience
The chemicals you use to clean surfaces and clothes may be causing large-scale ecological damage. "Phenyl and popular washing detergents contain toxic chemicals that eventually find their way to water bodies-drains, streams, rivers, oceans- and kill everything they come in contact with, especially fish," says Goa-based Claude Alvares, director of The Organic Farming Association of India, and editor, Organic Farming Sourcebook. "Switch to EM (effective microorganisms) cleaners to scrub your floors, sinks and toilet bowls, as well as to launder your clothes. You could also use detergents without phosphates (Henko is one such brand) to wash your clothes, or traditional cleaning agents like soapnut," he adds. Contact Maple Orgtech India Limited (09051498600) for EM distributors in your city.
Use Safer Paints
Lead-based paint is the most significant source of lead exposure at home. Various studies by Toxics Link, Centre for Science and Environment and Quality Council of India have found that popular brands of household paints contain lead that is higher than the 1,000 ppm (parts per million) limit specified by the Bureau of Indian Standards. Why is that important? Because, lead is a dangerous metal that harms every organ in your body, causing the most damage to the brain and the nervous system. "It can affect everyone, but kids below 6 are most vulnerable, mainly because they have developing brains and nervous systems. It leads to lower intelligence, cognitive disabilities, hearing problems and behavioural disorders in them," says Ravi Agarwal, founder-director, Toxics Link, New Delhi. Switch to lead-free paints for your walls. Asian Paints, Nerolac and Dulux are some options. Leadbased paint is a hazard when it chips, peels or cracks. "So when you repaint, make sure that you keep the kids away when the wall is being scraped. Cover your mouth (ask the painter to cover his too), to avoid ingesting the paint dust. Carefully clean the floor, window sills and nooks and crannies, to ensure there's no paint dust left," says Agarwal. "Since paints and varnishes contain other VOCs and harmful chemicals, keep doors and windows open to allow circulation of air," he adds.
Rethink Containers to Lose Weight
Look around: is your kitchen making you fat? Big plates, wide glasses, transparent cookie jars could sabotage your weight-loss mission. Because most of us have a habit of filling our plates and finishing what's on them, using a smallerthan-dinner-plate size can help you eat less. Swap your old plates for portion plates if you are on a weight-loss mission. Else, 10-inch diameter dinner plates are a good option. Similarly, rethink your glasses. People serve themselves more cola and juice when they pour it out in short, wide glasses than tall, slim ones, according to recent research. "That's because we focus on the height of beverages when pouring a potion. Switch to skinny glasses for sweet drinks and fill wider ones with water and other calorie-free quenchers," says Mumbaibased nutritionist Naini Setalvad. Also, just looking at tempting foods makes people feel hungrier. Plus, it triggers the release of feel-good chemical dopamine that may intensify a particular craving. Use opaque containers to store tempting snacks (cookies, matthi, bhujia) and stash them in an inconvenient spot to make them difficult to reach.
Sleep Better Than Ever
Your bed may be harbouring dirty little secrets. Dust mites, dander and pollen that thrive on pillows and mattresses not only worsen allergy and asthma symptoms but also aggravate skin conditions like eczema, says a study from the Annals of Allergy, Asthma & Immunology. "Stay safe by using fresh sheets and pillow covers every alternate day. Wash dirty ones in hot water and dry in the sun," says New Delhibased Dr Narendra Saini, the India representative, Global Hygiene Council. And for extra protection, invest in mattress and pillow protectors. These water-proof encasements create a barrier to prevent dust and germs from sinking into mattresses, pillows and quilts.

Lucky Country Inc. of Lincolnton, NC. The recalled products were sold in Costco and Smart &
Final stores located in California, Arizona, and Utah. The aforementioned Lot contained lead
levels as high as 0.18 parts per million which could provide up to 7.2 micrograms of lead per
serving. Lead is toxic if ingested by young children and can cause adverse health effects.
Lucky Country Aussie Style Soft Gourmet Black Licorice with Natural Ingredients is packaged
in a 1.5lb (680g) gusset bag with zipper. The package is red, white and black in color.
Please see the recall notice for specific information for consumers and contact information for
the company. You may also contact the CT Department of Public Health Lead Poisoning
Prevention & Control Program at 860-509-7299.
Lead in Spices
The Connecticut Department of Public Health, Lead and Healthy Homes Program (LHHP)
would like to make you aware of an investigation recently conducted by a local health
department (LHD) in collaboration with the LHHP, and the Department of Consumer Protection
(DCP). During the LHD’s investigation of a childhood lead poisoning case, no environmental
lead hazards were found at the child’s home. However, spices were identified as a potential
source of lead exposure, and the LHD collected and analyzed a common Indian spice known as
Asafoetida. Lab results indicated the sample of Asafoetida taken from the child’s home
contained 31.2 ppm of lead. The brand name of the Asofoetida was LG, manufactured by Laljee
Godhoo & Co., Mumbai, India.
The LHD in collaboration with the DCP and LHHP, collected six samples of Asafoetida powder
which included one sample from the lead poisoned child’s home, three samples from the store
where the child’s family purchased the spice, and two from an Asian grocer in a neighboring
town. In summary, two different brands and lot numbers of Asafoetida were tested. The sample
results ranged from 0.072ppm - 31.2 ppm.
The Food and Drug Administration (FDA), which oversees the safety of food products imported
into the U.S. does not have specific guidelines for screening lead in dried products like spices.
As a result, the FDA has not set a recommended maximum lead limit for spices or developed
regulations to remove lead contaminated products from retail sale.
However, it’s common knowledge that there is no safe level of lead in food. As such, if you are
conducting an epidemiological investigation as the result of a childhood lead poisoning case and
there are no common environmental lead hazard sources found on the property, you should
consider imported spices, home remedies, medicines/supplements, Ayurvedic products, and
cosmetics as other potential sources of lead exposure. Samples of these products should be
collected and submitted to a laboratory for analysis. We advise LHDs to work with the LHHP
and the DCP to remove food that is suspected or confirmed as contaminated from retail sales on
a case-by-case basis. A director of health may utilize Connecticut General Statutes sections 19a-
206 and 19a-101 for this purpose.
If you have any additional questions regarding ethnic remedies and other sources of lead
exposure, please contact your regional lead case manager. Laboratory analysis questions can be
directed to the DPH laboratory.
