For the last several years, phthalates have been making an impression on the public consciousness, as people become more aware of their pervasive use in all corners of society. These chemicals are used to make plastics flexible, as well as to preserve fragrances and help lotions penetrate the skin. Found in everything from cosmetics to toys (along with electronics and a wide array of household products), phthalates are utilized in so many places that avoiding them can begin to feel like an ongoing exercise in futility.
"Hormones are chemical messengers that travel throughout the body coordinating complex processes like growth, metabolism, and fertility. They can influence the function of the immune system, and even alter behavior...In response to a signal from the brain, hormones are secreted directly into the blood by the glands that produce and store them. These glands make up what is known as the endocrine system. Chemicals that interfere with the function of hormones are therefore known as endocrine disruptors."
Many people are exposed to these chemicals literally from the time they are in the womb, and they have been shown to have a wide range of negative effects. Birth defects have been linked to phthalates (which can be passed across the placenta in utero), as have reproductive issues. Premature or abnormal sexual development, along with insulin resistance, have also been linked to them.
While the situation appears to be admittedly bleak, there are steps you can take to mitigate your future exposure to phthalates. First and foremost, avoid plastics as much as possible (though that is admittedly not easy).
- Invest in a water filter - carbon filters can cut down on phthalates, which make their way into drinking water either through the treatment process or from pipes.
- Eat organic produce, meat, and milk - Certified organic produce doesn't make use of the pesticides and sewage sludge that traditionally provide a vector for chemicals to impact agriculture.
- Seek out proper plastics - Recycling codes 3, 6 and 7 are more likely to contain these chemicals
- Avoid fragrances whenever possible - New car smell? Phthalates. As are many perfumes and air fresheners. Avoid anything with synthetic fragrance, and seek out products that use natural essential oils instead.
- Vote with your dollars - We've talked about investing in green companies before on the Green Conscience blog, but in the case of phthalates and other chemicals, money makes a difference. Some manufacturers have taken their own initiative to remove these chemicals from their products. If you are so inclined, make sure your business goes to them (and not their competitors) and you'll naturally be pressing for the changes you want to see in the world.
