We are surrounded by human-made chemicals—more than 80,000 are in use in the United States today. Of those, only a few hundred have been tested for safety. Chemicals are so ubiquitous, they reach us before we’re even born: Researchers have found up to 300 contaminants in the umbilical cord blood of newborn babies.
Experts suspect this cocktail of chemicals in our water, food, air and homes may be part of the cause of the rising rates of some cancers, autism, diabetes and obesity. Young children, pregnant women and people with compromised immune systems are most at risk. While it may seem overwhelming to get control of our world’s rampant, potentially harmful chemicals, cleaning up the chemicals in your life is easier if you take it step by step. You can get started by reducing the quantity of these 10 chemicals in your house and yard.

1. Phthalates

Phthalates are endocrine-disrupting chemicals used to make #3 plastic (PVC or vinyl) flexible. PVC leaches phthalates when it’s heated or worn down. Phthalates are found in personal-care products and detergents, often labeled as “fragrance.” Phthalate exposure has been linked to early puberty in girls, a risk factor for later breast cancer.

To minimize: Never microwave plastic containers. Store food in glass or metal containers. Avoid vinyl flooring, shower curtains, PVC pipes, and products with “fragrance.”

2. BPA

Bisphenol A (BPA) is an endocrine disrupter found in reusable polycarbonate (#7 plastic) food and beverage containers (including baby bottles); the lining of food and beverage cans; in PVC (#3 plastic); and on receipts and money. Research links BPA to breast cancer, miscarriage, erectile dysfunction and heart disease.

To minimize: Never microwave or heat plastic containers, and store food in glass or metal containers. Avoid canned foods—choose bulk, frozen or fresh instead. Some companies such as Eden Organic offer BPA-free canned food. Buy “BPA-free” reusable water bottles. Wash your hands after handling receipts or money.

3. Chlorine

Used as a disinfectant in municipal water systems, chlorine is toxic, even at low concentrations. Studies link chlorine exposure through ingestion and showering with an increased risk of heart disease, allergic reactions and miscarriages, as well as increased rates of bladder, colon and rectal cancers. Chlorine irritates the eyes, nose and throat.

To minimize: You can filter chlorine with a whole-house filter or with a chlorine-filtering showerhead and a granular-activated charcoal drinking water filter. Avoid swimming in chlorinated water.

4. Radon

Radon is a natural, odorless radioactive gas that can seep into homes from the ground. Radon is the second leading cause of lung cancer (and the leading cause for nonsmokers) and can be detected with a test kit.

To minimize: Test for radon with a simple test kit, then call in a radon remediation contractor if the levels are too high—4 picocuries per liter (pCi/L) or higher. Levels between 2 pCi/L and 4 pCi/L can still pose a risk and in many cases can be reduced; consult a specialist.

5. PFCs

PFCs (perfluorochemicals) are persistent organic pollutants used on stain-resistant clothing and upholstery, cooking pans, fast-food wrappers, and inside pet food and microwave popcorn bags. Teflon, Scotchgard, Stainmaster and Gore-Tex are all PFCs. They have been associated with low-weight babies, abnormal thyroid hormone levels, liver inflammation and reduced immune function.

To minimize: Forego stain treatments on furniture or carpet; don’t wear clothing labeled stain- or water-resistant; avoid nonstick pans; pop popcorn on the stove; and choose personal-care items without “PTFE” and “perfluoro” in the ingredients.

6. Lead

Found in paint manufactured before 1978 and old plumbing, lead is a neurotoxin that can cause headaches, joint pain, high blood pressure, and reproductive and memory problems, as well as impair children’s brain and nervous system development.

To minimize: If you have peeling paint, (and your house was painted before 1978), clean up chips immediately and hire a certified lead abatement contractor. Do not remove lead paint yourself. Prevent chipping by sealing old paint with a clear, nontoxic sealant. If you suspect high lead levels, contact your doctor about lead testing for any children in the household.

7. Pesticides & Fertilizers

If it kills insects or weeds, it likely isn’t good for human health, either. Many common pesticides are known carcinogens. One chemical in many pesticides, dichlorvos, is associated with mammary tumors in rats or mice. Another, glyphosate, has been linked to non-Hodgkin’s lymphoma.

To minimize: Don’t use chemical pesticides or fertilizers on your lawn. Buy organic fruits and vegetables, or grow your own without artificial pesticides or fertilizers.

8. Formaldehyde

Formaldehyde is a flammable, pungent compound found in building materials, pressed-wood products, melamine (hard plastic) dishes and cigarette smoke. It can irritate the eyes, throat and mucus membranes, and cause headaches and nausea. Exposure may increase the risk of brain cancer and leukemia.

To minimize: Use “exterior-grade” pressed-wood products to limit formaldehyde exposure in the home. Before purchasing pressed-wood products such as plywood, paneling, particleboard, fiberboard, and furniture and cabinets, ask retailers or manufacturers about formaldehyde content.

9. Parabens

Parabens are used as preservatives in the cosmetic and pharmaceutical industries. While no causal link with cancer has been established, parabens are controversial because they weakly mimic estrogen, and researchers have found measurable concentrations in breast tumors. Studies show that methylparaben (in some sunscreens) may react with sunlight to damage skin.

To minimize: Test for radon with a simple test kit, then call in a radon remediation contractor if the levels are too high—4 picocuries per liter (pCi/L) or higher. Levels between 2 pCi/L and 4 pCi/L can still pose a risk and in many cases can be reduced; consult a specialist.

To minimize: Avoid cosmetics that list parabens or words ending in “-paraben” among the ingredients.

10. PBDEs & PBBs

Used as flame retardants in building materials, electronics, foam cushions and textiles, PBDEs (polybrominated diphenyl ethers) and PBBs (polybrominated biphenyls) accumulate in blood and fat tissues. Endocrine-disrupting PBDEs and PBBs may alter children’s brain development and cause learning and behavior problems. Exposure can decrease thyroid hormone levels and negatively affect reproduction.

To minimize: Cover or replace cushions or car seats where foam pads are exposed. Avoid rigid polystyrene (Styrofoam) insulation.

Early exposure to phthalates increased risk for childhood obesity.

Children with high levels of di(2-ethylhexyl) phthalate, a common type of phthalate, were five times more likely to develop obesity compared with children who had lower exposure to the chemical.

Di(2-ethylhexyl) phthalate (DEHP) belongs to a group of industrial chemicals believed to have endocrine-disrupting or hormone-altering properties. The chemical is used in products such as pacifiers, plastic food packages, medical equipment and building materials such as vinyl flooring, or soap, shampoo and nail polish.

“The prevalence of obesity has increased dramatically over the last 40 years; however, overeating and inactivity does not explain the epidemic,” Mi Jung Park, MD, PhD, of the Sanggye Paik Hospital at Inje University College of Medicine in Seoul, Korea, said during a press conference. “Children are of particular concern because they are more vulnerable to exposure.”

Park and colleagues included 204 children (105 obese, 99 controls) aged 6 to 13 years in their study and aimed to determine whether serum DEHP levels were linked to the development of obesity in Korean children.

“Prenatal exposure to endocrine-disrupting chemicals may contribute to the risk of childhood obesity,” Park said.

Previous research has concluded that phthalates may alter gene expression linked to fat metabolism, she said.

In this study, they analyzed nutrient intake, physical activity, household income, height and weight, body composition, fasting glucose, insulin, AST, ALT, uric acid and lipid profiles. They also divided DEHP measurements into four quartiles, from the lowest detectable level (40.2 n/mL) to the highest (69.7 to 177.1 ng/mL).

According to data, DEHP levels were higher in obese children (53.8 ng/mL) compared with controls (107 ng/mL; P<.0001). In addition, there was a positive correlation with BMI (P=.015), serum ALT (P=.047), uric acid (P=.038) and body fat mass (P=.029).

Serum DEHP levels did not have a significant association with HDL cholesterol, triglycerides, fasting blood sugar or fasting insulin, data found.

Moreover, the increased risk for obesity (OR=1.25; 95% CI, 0.51-3.01) was observed in quartile two of the study, showing an elevation of serum DEHP in a dose-dependent manner. The risk for obesity was also determined in quartiles three (OR=3.63; 95% CI, 1.48-8.91), and four (OR=5.04; 95% CI, 2.00-12.71), following adjustments for age, gender, physical activity, household income and daily caloric intake.

“Only a few chemicals have been studied in humans, until now; many more will be found below the tip of the iceberg,” Park said. “EDCs are ubiquitous and we are exposed to these chemicals throughout our lifespan; we should alert the public of this harm and make efforts to reduce this exposure.” – by Samantha Costa
