Toxic chemicals in your home could be linked to cancer, autism, and reproductive issues. Here are 4 of the most concerning.

Where they reside: Phthalates are part of the plasticizer family, which make plastic durable and flexible. Although Congress instituted a federal ban on phthalates in toys and children's products in 2008, the chemicals continue to be used in manufacturing. As of 2016, phthalates still represented a third of the plasticizer market. Among the long list of products containing phthalates are items like vinyl flooring, shower curtains, detergents, nail polish, hair sprays, shampoos, and perfumes.

The potential health effects: Trasande said phthalates are associated with a number of reproductive issues, including decreased reproductive functions in men and endometriosis in women. Additional studies have found a link between phthalates and obesity, ADHD, asthma, diabetes, and breast cancer.

How to limit exposure: Reducing exposure to phthalates is a challenge, given how many products contain the chemical. One helpful trick is to look for key words on the label. If a product was packaged in "recycling-code-3" plastic or contains the word "fragrance," phthalates could be present.

Where it resides: Bisphenol A, or BPA, is a chemical commonly found in plastics such as water bottles and food packaging. It's also hidden in household items like paper receipts and the linings of aluminium cans.

The potential health effects: Numerous scientists, including Trasande, have uncovered a link between BPA and obesity. The chemical has also been associated with coronary artery disease, increased blood pressure, and issues with female reproductive development. While the US Food and Drug Administration (FDA) has said that BPA is safe for humans, their assertion has been widely challenged by the scientific community.

How to limit exposure: To avoid BPA exposure, Trasande said, homeowners should stop microwaving plastic, scale back on canned food consumption, and replace plastic containers with an alternative like glass or stainless steel.

Where they reside: As the name suggests, flame retardants are designed to make products like electronics, furniture, carpets, and building materials less flammable. To date, 13 states have adopted policies that limit or ban flame retardants from certain products. But the chemicals still linger in the environment in soil, water, and air. They're also commonly found in household dust.

The potential health effects: Flame retardants have been associated with a litany of negative health effects, including thyroid cancer, ADHD, slower brain development, and decreases in children's IQs. Flame retardants in indoor dust could also cause allergies and asthma.

How to limit exposure: Frequent mopping and vacuuming can help reduce the likelihood of inhaling dust laced with flame retardant. Parents should also watch out for mattresses and children's toys that contain polyurethane foam.

As science uncovers more evidence of the dangers of these chemicals, the US Environmental Protection Agency (EPA) continues to lag behind. Thus far, the EPA has only banned a handful of chemicals, despite the presence of 80,000 on the US market.

Trasande called the EPA's framework for evaluating toxicity "over-simplified and "limited on a number of levels."

"We're recognizing that low-level exposure to an array of synthetic chemicals commonly used in our household products contributes to these diseases," Trasande said. "What little we know suggests broad consequences."
