Since moths chew holes through clothing and other textiles, people pack them in stinky toxic repellents to kill them. Studies on one active ingredient in repellents, paradichlorobenzene, found causes cancer in animals. Other types of moth balls use naphthalene, which after prolonged exposure can damage or destroy red blood cells, and stimulate nausea, vomiting, and diarrhea.
Ninety percent of households in the United States use some form of pesticide – a broad term encompassing a variety of chemical formulas that kill everything from tiny microorganisms to rodents. In 2006, the American Association of Poison Control Centers received nearly 46,000 calls regarding children under age 5 who had been exposed to potentially toxic levels of pesticides.
3. Pressed Wood Products
This faux wood takes bits and pieces of logs and wood leftovers and combines them together. Pressed wood products include paneling, particle board, fiberboard and insulation, all of which have been particularly popular for home construction since the 1970s. However, the glue that holds the wood particles in place may use urea-formaldehyde as a resin. The U.S. EPA estimates that this is the largest source of formaldehyde emissions indoors. Formaldehyde exposure can set off watery eyes, burning eyes and throat, difficulty breathing and asthma attacks. Scientists also know that it can cause cancer in animals. The risk is greater with older pressed wood products, since newer ones are better regulated.
4. Chemicals in Carpets
Indoor carpeting has recently come under greater scrutiny because of the volatile organic compounds (VOCs) associated with new carpet installation. The glue and dyes used with carpeting are known to emit VOCs, which can be harmful to your health in high concentrations. However, the initial VOC emissions will often subside after the first few days following installation.
5. Laser Printer Chemicals
2007 study found that some laser printers give off ultra fine particles that can cause serious health problems. Another study confirmed that laser and ink-jet printers can release volatile organic compounds (VOCs) and ozone particulates. All of these have been linked with heart and lung disease.
6. Lead Paint
In 1991, the U.S. government declared lead to be the greatest environmental threat to children. Even low concentrations can cause problems with your central nervous system, brain, blood cells and kidneys. It’s particularly threatening for fetuses, babies and children, because of potential developmental disorders. Many houses built before 1978 contain lead paint. Once the paint begins to peel away it will release the harmful lead particles that you inhale.
7. Air Fresheners and Cleaning Solutions
Air fresheners (air poisoners) and cleaning solutions, when used excessively or in a small, unventilated area, can release toxic levels of pollutants. This comes from two main chemicals called ethylene-based glycol ethers and terpenes. While the EPA regards the ethers as toxic by themselves, the non-toxic terpenes can react with ozone in the air to form a poisonous combination. Air fresheners in particular are linked to many volatile organic compounds, such as nitrogen dioxide, and some fresheners also contain paradichlorobenzene, the same chemical emitted by mothballs. Don’t forget to avoid, or remove, any air fresheners in vehicles…think of the danger of all those synthetic chemicals in that tight enviroment, especially in hot water.
8. Baby Bottles and BPA
Canada has taken the first steps to outlaw the sale of baby bottles made from polycarbonate plastics, which are the most common type on the market. It has done so because the plastics are made with a chemical called bisphenol-a (BPA). BPA has a structure very similar to estrogen and for that reason is referred to as a “hormone disruptor.” Hormone disruptors can interfere with natural human hormones, especially for young children.
9. Flame Retardants
Commonly used in mattresses, upholstery, television and computer casings and circuit boards, flame retardants use polybrominated diphenyl ethers, or PBDEs for short. Two forms of PBDEs were phased out of use in manufacturing in the United States in 2004 because of related health threats, but the products containing them linger on. Studies have linked PBDEs to learning and memory problems, lowered sperm counts and poor thyroid functioning in rats and mice. Other animal studies have indicated that PBDEs could be carcinogenic in humans, although that has not yet been confirmed.
10. Cosmetic Phthalates
Phthalates, also called plasticizers, go into many products including hair spray, shampoos, fragrances, and deodorants. Phthalates bind the color and fragrance in cosmetic products, and are also used to increase the durability and flexibility of plastics. Like BPA, these hormone-like chemicals are linked to reproductive and developmental problems in animals. Because of these findings, California and Washington state have banned the use of phthalates in toys for younger children.
11. Vinyl Chloride, aka “The New Car Smell”
Vinyl chloride off-gasses from the interiors of new cars. At high levels, this known carcinogen causes severe liver damage, ballooning of the fingertips, migraines, serious allergic responses, throat restriction and in severe cases anaphylaxis, to mention a few symptoms. Make sure you ventilate a new vehicle and, when possible, use a portable air purification system that plugs into the lighter. If you can take delivery close to summer months, you can close all the windows and set it in full hot sun when not in use and then air the interior prior to occupying…this helps to off-gas chemicals faster. Those who are victims of multiple allergic responses (multiple chemical sensitivities, and hypersensitive will never be able to tolerate the chemicals in a new vehicle, especially one with leather seats because the leather is tanned with formaldehyde).
