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.

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

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. Try the ones from Protect-a-Bed and Hush Sleep Studio.

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.

What are the Health Effects of Fiberglass?
The main sources of fiberglass particles in indoor environments includes, but are not limited to, ceiling tiles, debris from renovation projects, or degradation of HVAC system liners.

What are the Health Effects of Fiberglass?
Staphylococcus aureus Poses Threat for Indoor Environments
Mold, Taxes and Death – What is the Commonality?
Fiberglass is a type of fiber primarily composed of glass that is used in a wide variety of applications, and is predominantly used as a residential and commercial thermal insulator. As an insulator, it maintains a resistance to the spread of heat (known as the R-Value), cold and sound in structures, vehicles, aircraft, etc. By trapping pockets of air, it keeps areas warm in the winter and cools in the summer and thereby serves as a excellent way to increase energy conservation all the while maintaining comfort.
Glass has been woven into small amounts of coarse fibers for many centuries, even by the ancient Egyptians, but fiberglass did not exist in its modern (insulation) form until 1932 as a result of an accident. An Owens-Illinois researcher named Dale Kleist was attempting to create a vacuum-tight seal between two glass blocks when a jet of high-pressure air turned a stream of molten glass into fine fibers. He had unintentionally discovered an effective method to produce large amounts of fiberglass particles, a method that he would refine in later years. In the United States, the first commercial production of fiberglass was started by Illinois Glass Company and the Corning glass work in 1939.
The main sources of fiberglass particles in indoor environments includes, but are not limited to, ceiling tiles, debris from renovation projects, or degradation of HVAC system liners. These particles are very important from health and hygiene point of view. OSHA regulates fiberglass particles as a nuisance dust since 1991. Health implications from these particles may vary depending on the fiber size and type of exposure. Skin/eye irritation, rashes, soreness in nose and throat, asthma like symptoms, upset stomach etc. are some common symptoms due to contact, inhalation and ingestion of relatively larger fiberglass fiber although the smaller fragments (less than 0.5 micron) are capable of reaching the lower part of the lungs increasing the chance of adverse health effects.
Health effects from exposure to fiberglass can be different depending on the fiber size and type of exposure. Larger fibers have been found to cause skin, eye and upper respiratory tract irritation. There are other possible health effects:
•A rash can appear when the fibers become embedded in the outer layer of the skin. No long-term health effects should occur from touching fiberglass.
•Eyes may become red and irritated after exposure to fiberglass.
•Soreness in the nose and throat can result when fibers are inhaled. Asthma and bronchitis can be aggravated by exposure to fiberglass.
•Temporary stomach irritation may occur if fibers are swallowed.
Little information is known about the health effects caused by small fibers. Smaller fibers have the ability to reach the lower part of the lungs increasing the chance of adverse health effects.
People who work with fiberglass or who have worn-out duct work lined with fiberglass in their homes or workplace may have long-term exposure to fiberglass. There is no evidence that fiberglass causes cancer in people. Animal studies have shown an increased risk of cancer when fiberglass fibers were implanted in the lung tissue of rats, but these studies are controversial because of how the fibers were implanted.
Under a microscope, fiberglass appears as a smooth-walled, colorless or slightly pigmented surrounding, entire margin, elongated tube-like structure with varying size ranges, 1 to > 1000 microns.
Ideally, there should not be any air or surface-borne fiberglass fibers in indoor environments. An independent study performed by EDLab at Pure Air Control Services Inc., utilizing over 10,000 indoor air samples, reveals that 99% of the air and surface samples collected were deemed negative for the presence of fiberglass fiber. Samples deemed positive for these particles indicated that the concentration of fiberglass fiber is greater in surface samples (up to 176 cts/cm2) in comparison to air samples (66 cts/m3). Additionally, this independent study suggests the concentration of fiberglass fiber in the air should be less than 5 cts/m3 and 4 cts/cm2 in surface samples.

The Canary: Innovation in Digital Radon Gas Monitoring
The Canary: Innovation in Digital Radon Gas Monitoring by Corentium AS
The Norwegian company Corentium AS has developed a novel digital radon gas monitor for homeowners, workplaces and the public sector. Compared to traditional technology, the battery powered monitor ‘Canary’ makes it much easier to locate the radon entry in the buildings.
.The new digital and battery powered monitor ‘Canary’ is a paradigm shift in radon gas measurement procedures Oslo, Norway (PRWEB) March 12, 2013
There are epidemiological evidences that indoor radon exposure is responsible for a substantial number of lung cancers in the general population. The development of the monitor ‘Canary’ (http://www.corentium.com/eu) is largely a response to the 2009 UN World Health Organization report ‘WHO handbook on indoor radon. A public health perspective’ which provided detailed recommendations on reducing health risks from radon gas.
(http://www.who.int/ionizing_radiation/env/radon/en/index1.html)
Many countries have over the last few years developed national radon programs, also demanding more appropriate technologies for radon measurement and monitoring. This has inspired the Norwegian company Corentium AS to develop accurate and affordable digital instruments for homes, workplaces, schools and kindergartens.
In most fields, technology has for long moved from the analogue to the digital age. Not so when it comes to radon gas monitoring technology. The traditional technology – track edge film – is still the most prevalent in the market. The film has to be placed for 2-3 months in the room to be measured, and has then to be sent to a specialized laboratory for development.
The new digital and battery powered monitor ‘Canary’ is a paradigm shift in radon gas measurement procedures. It enables people to monitor radon continuously themselves – making radon gas diagnostic much easier, and reducing dependency on third-party services and consultancies. After measuring for a few days, one gets indications about the radon level. Canary gives the possibility to read the average value for 1 day, for 7 days, and the accumulative average up to a year.
The Canary is also ideal for measuring the effect of simple mitigation measures – for example increased ventilation.
The radon monitor Canary is tested in renowned laboratories like NIRS in Japan, BfS in Germany and SURO in the Czeck Republic, and proved to be within the laboratories' own measurement uncertainty.
It is estimated that up to 14% of lung cancers is attributed to radon gas radiation. Radon is the second cause of lung cancer after smoking. Analyses indicate that the lung cancer risk increases proportionally with increasing radon exposure. As many people are exposed to low and moderate radon concentrations, the majority of lung cancers related to radon are caused by these exposure levels. This indicates that in countries where radon is found, most buildings should be monitored for radon as part of general preventive health care.
The name Canary emanates from older times, when canary birds were used in mines to warn the workers against dangers. If the level of dangerous gases was too high, the canary birds stopped to sing. The mine workers then had to get out of the mine. To learn more about Canary, visit http://www.corentium.com/eu.
About Corentium AS:
Corentium AS was established in 2008, and is based in Oslo, Norway. Corentium is researching, developing and manufacturing technology for radiation monitoring. Behind Corentium stand researchers and developers from CERN in Geneva, The Norwegian University of Science and Technology, and the Department of Physics at the University of Oslo.

The dirty truth on green cleaning products
By Deirdre Imus
Green Your World
Published March 11, 2013
FoxNews.com
When a product becomes trendy or appealing to consumers, manufacturers respond.
It’s why over the last few years, you’ve probably noticed a proliferation of “all-natural” this, “organic” that and “green” as far as the eye can see, whether on food packaging, cleaning product labels, clothing, or furniture.
It can be difficult – almost impossible – for the average person to make sense of it all, and to decipher between the good, the bad and the truly awful. After all, the terms “all-natural” and “organic” can easily refer to substances that are indeed both natural and organic – and also bad for your health.
For nearly 15 years, I have been manufacturing green cleaning products, which are derived from plants and minerals; free of harmful chemical ingredients; made from biodegradable ingredients; effective; and safe to use in your home, school or office building. I take my responsibility to consumers very seriously, and have had our product line third-party tested and verified so that you can trust they are as healthy as we say.
But not all cleaning product manufacturers take this extra step, and some are downright dishonest about being natural, organic, or green. Cleaning product manufacturers are not required by federal law to disclose ingredients on their labels or websites, so the only way for consumers to discover what’s inside is to read each product’s material safety data sheet (MSDS), a federally mandated list of ingredients provided so that workers are aware of chemical hazards in cleaning products used on the job.
It is practically pointless, however, for anyone without a working knowledge of the cleaning products industry to read an MSDS, because they are chock full of long, complicated ingredient names that give no indication of whether a product is safe or not. You may know that ammonia is dangerous, but can you identify – or even pronounce – an ingredient called 2-butoxyethanol?But, it is contained in some products that are touted as 'green.'
Actually, 2-butoxyethanol is a solvent that can cause eye irritation and damage red blood cells, according to the Environmental Working Group (EWG), one of the nation’s leading environmental health research and advocacy groups. It is hardly a green ingredient, as the product’s name implies.
Such misleading nomenclature is exactly why we need a more concise, easily accessible system to help consumers make informed decisions about which cleaning products to buy, and which to avoid like the plague.
Currently, you can locate healthy products by searching databases like the EWG Guide to Healthy Cleaning, or checking to see if your favorite product is recognized by the U.S. Environmental Protection Agency’s Design for the Environment Program. This can be helpful, but is not entirely effective: Each database, listing or guide requires different criteria to meet its set of unique standards for green validation.
Which leads me to this: How can you find the best, healthiest and safest cleaning products to use in your home?
Here are some helpful hints of what to look for, regardless of a product’s name, labeling, or database rating:
• Full disclosure of all ingredients
• Ingredients should be derived from plants and minerals
• Must not contain petroleum-derived or petro-chemical ingredients
• Label must stipulate the origin of fragrance and whether it is naturally derived or not
• All ingredients should be biodegradable
• No animal-testing, no animal-derived ingredients
• Finished product must be safe for septic tanks and grey water
• Must not be corrosive
• Must not contain compounds that cause or contribute to the creation of greenhouse gases or ozone depletion
• Must be free of any known human carcinogens, mutagens, teratogens, and endocrine disruptors
