The answer may surprise you, but it’s dust!
Believe it or not, household dust can be one of the biggest exposures to toxic chemicals in the home, especially for infants and toddlers, who crawl on the floor, chew on their fingers and toys, and spend up to 90% of their time indoors. And these chemicals could be affecting their brain development, or even lowering their IQ.
Studies have shown that some of the most common toxins found in household dust include flame retardants, phthalates, PFCs, fragrance chemicals, and lead. In addition to these toxins being associated with hindered brain development, they have also been linked with health issues such as hormone disruption, cancer, and reproductive damage.
Children are especially susceptible to toxins because their detoxification pathways are not fully developed, meaning that they can’t detoxify and flush the chemicals out as quickly as adults can. Being exposed at a young age to many of these toxic chemicals, many of which have never been tested, also means the chemicals have longer to do their damage over time. Important organ systems are still developing in children’s bodies, and toxins can affect or interrupt that development.
Neurodevelopmental problems such as ADHD and learning disabilities are on the rise and affect approximately 20% of school-aged children and adolescents. And according to Philippe Grandjean, adjunct professor of environmental health at the Harvard School of Public Health:
“The greatest concern is the large numbers of children who are affected by toxic damage to brain development in the absence of a formal diagnosis. They suffer reduced attention span, delayed development, and poor school performance. Industrial chemicals are now emerging as likely causes.”
Several of these toxic chemicals that can affect brain development are commonly found in dust, and they include:
Phthalates. These are linked to developmental issues, and are linked to lower IQ in children born to mothers who had the highest levels when tested. Phthalates are found in vinyl flooring, vinyl shower curtains/shower curtain liners, soft rubber toys, and hide in fragrances (in personal care/beauty and cleaning products, candles, air fresheners, etc).
Flame Retardant Chemicals. These chemicals have been shown to cause neurological effects in children, such as brain damage, lower IQ, hindered brain development, persistent behavior problems, and problems with memory and motor skills. They’re found in furniture with polyurethane foam, electronics and some brands of high chairs, mattresses, car seats, and some children’s pajamas.
Polychlorinated biphenyls (PCBs). Associated with reduced cognitive function in infancy and childhood, and exposure to PCBs before birth is linked to “neurodevelopmental deficits.” Although they were banned in 1979, this family of chemicals can can still be found in the environment in foods, particularly fish, household dust, and even in breastmilk.
Lead. Neurological effects and lower IQ are the most common effects of lead exposure, and studies have shown that there are no safe exposure levels of lead. It is commonly found in paint (in homes built before 1978), cosmetics, art supplies, air, water, soil, certain careers and industry (lead can be brought into the home from those exposed at work).
The good news is there are simple things you can do, and it doesn’t mean you have to vacuum and dust 24/7. Don’t stress about dusting every room everyday. Do what you can, but especially concentrate on places where your family spends the most time, such as floors and play areas where your children play the most, and in bedrooms, the family room, and the other most-used areas of your home.
Here are some other things you can do:
Follow these tips, but most of all, don’t stress! Do what you can every day, but especially concentrate on places where your family spends the most time. Pretty soon you’ll have a more dust-free and healthier home!
