Our Sensitive Sons

The common belief within the toxic illness community seems to be that women are more likely than men to develop the condition. This belief is reinforced by the fact that online support groups appear to have a greater percentage of female than male participants. I was somewhat surprised, then, to read an article this week that detailed ways in which boys may be more vulnerable to environmental pollutants than their female counterparts are.

The article, published in Environmental Health News, makes the following points:

• There’s a stronger link between air pollution and autism in boys.

• The insecticide chlorpyrifos, found in Dursban and other products, seems to reduce the IQs of boys more than girls.

• Boys are more susceptible to damage from low-level lead exposure.

• Phthalates, found in vinyl and many other products, have been linked to larger behavioral changes, primarily aggression and attention disorders, in boys

.

• A study found that high in-utero exposure to Bisphenol A (BPA), another ubiquitous chemical, caused hyperactivity, aggression, and anxiety in boys, but not girls. The boys were also born with lower thyroid hormones, while female levels were normal.

The author explains the findings by noting that the pre-birth development of a female is simpler than that of a male. It takes a greater number of cell divisions to make a male, and with each division comes a greater vulnerability to toxic exposures.

After birth, these vulnerabilities continue. In females, the XX chromosome offers a bit of back-up protection, with a healthy X able to take over for one with a genetic defect. Males, with their XY makeup, have no such backup system. The article also notes that X chromosomes carry more genetic information, so the XY combination may mean a loss of brain development proteins or repair mechanisms.

In addition, estrogen protects the brain. Their lower estrogen levels mean that male brains are more fragile and prone to injury. Hormone imbalances may contribute to a wide range of chemical-related health effects, because many chemicals are endocrine disruptors which suppress or mimic hormones.

If it’s true that the common belief is that women are more vulnerable to chemical illness and the truth is the opposite, why is that?  Perhaps it’s because we still have a lot to learn as a culture about all the possible symptoms that toxic exposures can cause. There will always be differences between boys and girls, but maybe some of the “natural boy” traits we’ve assigned to the gender, such as aggression, hyperactivity, and lack of focus, aren’t entirely natural after all.

Chemicals and Conception

Celebrating Mother's Day yesterday reminded me again of what a blessing it is to be the mother of two amazing young men. As I ponder the gift of motherhood, I can't help but think of a number of people I know who would very much like to be parents, but have found that goal difficult to achieve. There are many possible reasons for infertility, but a factor that may be overlooked, and that can be controlled to an extent, is exposure to chemical toxins. (How did you know I was going to say that?)

Earlier this year, the journal Environmental  Health Perspectives published a study that examined "persistent pollutants" and the time to pregnancy of couples wishing to conceive. The study and a report of it published in E Magazine noted the following:

• Couples exposed to toxins known as persistent organic pollutants took longer to become pregnant.

• Men’s chemical exposures were more important to the equation than their partners'.

• The concentration of chemicals found to delay conception was lower than the average found in the U.S. population.

An online article entitled "Toxins and Fertility" notes that only about 5 percent of the almost 80,000 chemicals used in the US today have been tested for their reproductive effects. Despite that, we do know that certain chemicals may cause problems for couples wishing to become parents. The article and a fact sheet produced by Safer Chemicals, Healthy Families list the following chemicals that may affect reproduction:

• Phthalates, which are widely used and may be found in nail polish, shampoo, conditioner, lotion, antiperspirant, sunscreen, gum, candy, medications, and many other places

• Parabens, added to a wide range of household products, including bath products and cosmetics

• Bisphenol A (BPA), which can be found in polycarbonate plastic and some food and beverage can linings

• Perfluorinated compounds (PFCs), commonly used in stain-proof and non-stick products

• Cadmium, a metal used in pigments, metal coatings, plastics, and batteries

• Fluoride, added to many municipal water supplies

• Common pesticides and fungicides, including Vinclozolinis, Kepone, DBCP, ethylene dibromide, and  Methoxychlor (MCX)

• Triclosan (Microban),found in anti-bacterial soaps, dental products, cosmetics, deodorant, first aid products, kitchenware, appliances, toys, and more

The chemicals listed are linked to a wide range of other health effects as well. Avoiding them benefits us all.

A Fresh Blog Post

I've been thinking about the word "fresh" recently. Although there are alternative meanings, the general definition of the word is "new."  Often something fresh replaces something old, stale, or worn-out. We put on fresh socks or ask a friend to help us think of some fresh ideas for a project.

The air inside a building gets contaminated by the products used within it. In addition, humans inhale oxygen and exhale carbon dioxide, so when people are in a building, the air gets progressively less healthy from the simple act of breathing. We replace old, stale air with new, fresh air by opening windows or using ventilation systems. In no way whatsoever do we improve air quality by using those ridiculously named products known as “air fresheners."

 Here are a handful of "air freshener" facts:

• The U.S. Environmental Protection Agency (EPA) reports that most air fresheners contain formaldehyde and petrochemicals. They also contain a chemical known as 1,4-Dichlorobenzene (1,4,-DCB) which is an EPA-registered pesticide. It can cause cancer and lung damage and increases asthma rates. The chemical "freshens" the air by damaging nasal receptors. It does not remove odors, but removes people's ability to smell them.

• A study comparing homes in which air fresheners were used every day with those in which they were used once a week or less found that babies in the daily-use homes had significantly more earaches and diarrhea, and their mothers suffered nearly 10% more headaches and had a 26% increase in depression.

• Many air fresheners contain acetone and propane. They are toxic to the heart, blood, respiratory system, skin, gastrointestinal system, kidney, nervous system and liver.

• Exposure to air freshener chemicals as little as once a week can increase your risk of developing asthma symptoms by up to 71%.

• Most air fresheners contain phthalates, which are hormone-disrupting chemicals that can cause birth defects and infertility. These chemicals are even found in air fresheners designated as "unscented" or "all natural".

• The human body stores chemicals like those found in air fresheners in fatty tissue. The body may hold onto fat as a way to protect itself from the release of the toxins.

• Air freshener chemicals, including camphor, phenol, ethanol, formaldehyde, and artificial fragrances can cause a wide variety of health symptoms, including dizziness, coughing, rashes, mental confusion, and headaches, including migraines.

• One study found that women with the highest usage of household chemicals, including air fresheners, had twice the risk of breast cancer of those with the lowest chemical usage rates.

Although air fresheners abuse and misuse the word "fresh," they aren't the only product to do so. I recently saw an advertisement for a laundry detergent that claimed it now had a higher percentage of "freshness."  Really?  I imagine what the marketers mean is that more fragrance chemicals have been added to the already potent and toxic mix. It's easy to get duped by marketing ploys, but we don't have to buy into the crazy-ness. We can break away from the crowd. We can have a fresh perspective. We can make a fresh start.

A Bit of Good News

There's some good news on the toxins-in-common-products front this week. The Johnson and Johnson company has announced plans to remove a number of problematic chemicals from its products by 2015. The company had previously begun moving in a safer direction by setting a goal of 2013 for reformulating its baby product line.

The move comes after several years of pressure from health and environmental groups. Chemicals to be removed include formaldehyde, which is released from common preservatives, and triclosan, a widely-used antibacterial ingredient. Phthalates, certain fragrance ingredients, and some parabens will also be eliminated.

I have to admit to a bit of cynicism. History shows that sometimes toxic ingredients are removed from products only to be replaced with something that later proves to be equally problematic. I also doubt that enough health-impacting ingredients will be removed to make most of the products safe for those of us with serious chemical sensitivities.

Still, there is reason to be pleased with the news. In a New York Times article on the announcement,  a Johnson and Johnson official is quoted as saying that “there’s a very lively public discussion going on about the safety of ingredients in personal care products.”  The fact that manufacturers are beginning to hear and respond to the discussion is certainly positive.

Activists hope that other manufacturers will follow Johnson and Johnson's lead. The Campaign for Safe Cosmetics plans to continue to put pressure on other companies to do so. There are more than 175 nonprofit groups represented in the coalition.

The work of advocates and activists is important and welcomed, but none of us need to rely on them or wait for manufacturers to make changes. We can value our health and the health of those around us enough to make safer product choices now. Every purchase we make not only impacts us in the present, but is a vote telling manufacturers what we want to see on the shelves in the future. No one can force us to buy toxic products. We get to choose what we buy and what we use. Every day we get to make that choice and every day it has consequences. Let's choose wisely.
