Phthalate Exposure Linked to Attention Deficit Disorder in Children

January 31st, 2010

Phthalatesare primarly used as plasticizers, chemicals added to plastics to increase their flexibility, transparency, durability and longevity.  They are used in a wide variety of products including cosmetics and almost every brand of perfume.

A study in the Environmental Health Prospectivesjournal found a link between the amount of phthalate exposure and Attention Deficit Disorder.  In layman’s terms, more phthalates = more behavioral problems.

Children exposed in the womb to chemicals in cosmetics and fragrances are more likely to develop behavioral problems commonly found in children with attention deficit disorders, according to a study of New York City school-age children published Thursday.  Scientists at Mount Sinai School of Medicine reported that mothers who had high levels of phthalates during their pregnancies were more likely to have children with poorer scores in the areas of attention, aggression and conduct.

Where can you find phthalate free products?

According to Big Green Purse the following cosmetic companies sell phthalate free products:

Burt’s Bees– Lip balms, glosses, sticks and shimmers; face cleansers, toners, complexion bars, moisturizers, eye crèmes and exfoliating scrubs; shampoos and conditioners; toothpaste and peppermint breath drops; eye make-up and face powder; various “Baby Bee” products and a growing list of “Men’s Grooming” choices. Increasingly available in mainstream grocery stores, drugstores, and pharmacies.
Eco Bella Organics – Includes perfumes, bath and body products, cosmetics, and skin and hair care products. Often available in organic and natural foods stores and food co-ops.
Aubrey Organics – Products are made primarily with herbals, essential oils and vitamins. Includes baby care, bath products, hair care and color, hand and body lotions, makeup, skin care, soaps, toiletries, sun protection, and hair and skin essentials for men. Often available in organic and natural foods stores and food co-ops.
Tom’s of Maine – Offers 90 oral and body care products, sold at 40,000 retail outlets in the U.S. and around the world. Products include toothpaste, deodorant, mouthwash, soap, shaving cream, and dental floss.
Honeybee Gardens – In addition to a variety of lipsticks, powders, eyeliner, eye shadow, hair spray, shampoo, and conditioner, Honey Bee manufactures water-based nail polish, including one brand that can peel off without need of nail polish remover.

 Phthalates are also present in toys and other plastic products. 

Avoid PVC plastic. Unless made by a U.S. manufacturer who has indicated the product is phthalate-free, avoid soft plastic toys and soft vinyl products with a strong plastic smell such as plastic shower curtains. For information on PVC-free products for the home, office, and building materials, check out the resources available at: http://www.besafenet.com/pvc/documents/PVC-Guide-1.pdf.

Limit your and your children’s exposure to phthalates by considering the chemicals present in products you purchase.

Physics May Change Forever Thanks to the Hadron Collider

The Large Hadron Collider (LHC), the world’s largest and highest energy particle accelerator, is located near the Franco-Swiss border near Geneva, Switzerland.  The particle accelerator was built to study the collison of particles.  Scientist hope that this collision will answer the most fundamental questions in physics, the laws governing forces among objects, the structure of space and time, and the intersection between general relativity and quantum mechanics.  The collider will look for the existence of the hypothesized Higgs boson that will explain why matter has mass. 

The 9 million dollar budget for the LHC is the most expensive scientific experiment in history.  The information generated from the project is expected to generate more data then in all the libraries in the world.   Construction on the project began in 1995 and was completed in November 2009 and used more steel than in the Eiffel Tower.

In coming weeks, the international team of physicists and engineers who built the machine in a 17-mile circular tunnel 300 feet underground is planning to gradually increase the energies in each of the two proton beams.

The first results are expected in first quarter of 2010.

The upcoming experiments at the Large Hadron Collider have sparked fears among the public that the LHC particle collisions might produce doomsday phenomena, involving the production of stable microscopic black holes or the creation of hypothetical particles called strangelets.  Two CERN-commissioned safety reviews have examined these concerns and concluded that the experiments at the LHC present no danger and that there is no reason for concern, a conclusion expressly endorsed by the American Physical Society.

Currently, the intensity of the beams is increasing within the collider and in the coming months they will reach full speed.  The experiment promises to change the understanding of physics and we are lucky enough to be around to experience it.
