Let’s talk about something that affects us all – chemicals in our homes and buildings. Construction materials, furniture, flooring, wall finishes, even the air we breathe indoors often contain them. It’s a topic that can feel overwhelming, but knowledge is power. So let’s break it down together.
To begin with, it is important to remember that their concentrations and presence can vary between products and manufacturers. Additionally, chemical usage and labeling regulations differ between countries.
Understanding the chemicals present in our built environments is crucial for maintaining a healthy living space. Here’s a breakdown of common indoor chemicals, their sources, health issues, and the damage to the environment they cause.
Formaldehyde
what it is
Formaldehyde is a colorless gas with a strong smell, commonly produced through industrial chemical processes.
Where You’ll Find It
- Adhesives: Commonly used for bonding wood, fabric, and other materials, often containing formaldehyde.
- Plywood: Manufactured with formaldehyde-based adhesives.
- Particleboard: Bonded with formaldehyde-based resins.
- Carpets: May contain formaldehyde in adhesives or treatments.
- Curtains: Treated with formaldehyde finishes for wrinkle resistance or flame retardancy.
- Furniture: Especially in MDF and particleboard, which use formaldehyde resins.
- Flooring: Laminates and engineered wood often contain formaldehyde in adhesive layers.
Health issues
Short-Term Effects:
- Respiratory Irritation: Exposure can lead to coughing, wheezing, throat irritation, worsened asthma, and breathing difficulties.
- Allergic Reactions: Some individuals may experience skin rashes, itching, and hives, especially if they are sensitive to formaldehyde.
- Eye and Nose Irritation: It can cause redness, itching, and watering of the eyes, along with a runny or congested nose, sneezing, and nasal irritation.
- Headaches and Dizziness: Prolonged or high-level exposure is associated with headaches and dizziness.
- Nausea: Inhalation of formaldehyde vapors may lead to feelings of nausea.
Long-Term Effects:
- Weakened Respiratory Defenses: Long-term exposure can increase susceptibility to respiratory infections like colds and flu.
- Skin Sensitization: Repeated contact can lead to skin redness, itching, swelling, and sensitization, making the skin more reactive to formaldehyde and similar substances.
- Worsened Asthma Symptoms: Individuals with asthma may experience increased coughing, wheezing, and shortness of breath, with prolonged exposure potentially worsening the condition.
- Carcinogenicity: Formaldehyde is classified as a known human carcinogen, with long-term exposure increasing the risk of certain cancers, especially nasal and nasopharyngeal cancer, as well as leukemia.
- Chronic Respiratory Conditions: Extended exposure to formaldehyde has been linked to the development of chronic bronchitis and other long-term respiratory conditions.
Environmental Harm It Causes
- Indoor Air Quality: Formaldehyde off-gases from products and building materials, leading to indoor air pollution affecting air quality.
- Long-Term Persistence: Formaldehyde production harms the environment by releasing air pollutants and contributing to greenhouse gas emissions. As a pollutant, formaldehyde contributes to smog and lingers in the environment for extended periods, worsening air quality.
How to avoid or find safer Alternative:
- Choose low-formaldehyde products labeled “low formaldehyde” or “formaldehyde-free”.
- Choose Solid wood or metal furniture instead of particleboard or pressed wood.
- Choose carpets and curtains made of cotton, wool, or jute without stain-resistant finishes.
- Natural fibers: Choose curtain and drapes made from natural materials like cotton, linen, or hemp are generally free from formaldehyde. Look for curtains certified organic or made with natural dyes and finishes. Unprocessed curtains, without any additional treatments are often the safest option. Formaldehyde can be used as a finishing agent to reduce wrinkles and creases and are sometimes used to make curtains flame-resistant.
- Ventilate the space and allow for off-gassing: Open windows and use exhaust fans to reduce indoor formaldehyde levels. Let new furniture and building materials air out in a well-ventilated area or outside before moving them into your living space to minimize formaldehyde emissions.
- Use natural finishes: Use water-based paints, stains, and sealants with low or no VOC content.
- Conduct research: Check with manufacturers for formaldehyde content information and look for certifications like CARB Phase 2 compliance.
- Consider secondhand options: pre-owned items are less likely to emit formaldehyde.
Flame Retardants
What it is
Polybrominated Diphenyl Ethers (PBDEs) are synthetic chemicals used as flame retardants in products like electronics and furniture. They are persistent in the environment, meaning they don’t break down easily, and can accumulate over time in both humans and animals. This buildup occurs through ingestion, inhalation, or skin contact with dust or materials containing PBDEs. Over time, these chemicals can collect in fatty tissues, leading to potential health risks such as hormone disruption and developmental issues. Similarly, they accumulate in the environment, contaminating air, water, and soil, posing long-term ecological hazards.
Fire safety standards require flame retardants to be added on furniture, upholstery and building materials. This chemical addition possibly slow down the spread of fires, but they are not as effective as promised.
Research shows it delay fires only by a few seconds and makes it more harmful because the burning product gives off more toxic gases and smoke which is the leading cause of fire deaths.
Worse, they break down into toxic gases that continually migrate from products we use daily, dropping into dust, food, and water. This leaves us vulnerable to inhalation or direct contact with our skin.
Especially concerning for young children who frequently put their hands in their mouths have the highest exposure. Toddlers have 3-10 times more flame retardants then adults which affects their developing brains and reproductive organs also linked with lowered IQ and hyper activity. Cats have levels 10-100 times more.
In 2013, California’s Technical Bulletin 117 (TB 117), prioritized fire safety without requiring the use of harmful flame retardants. This allows for better fire safety in furniture and children’s products without mandating flame retardant use.
Where You’ll Find It
- Furniture: Sofas, chairs, mattresses, pillows, and upholstery materials.
- Electronics: TVs, computers, laptops, smartphones, and other electronic devices.
- Children’s Products: Car seats, strollers, high chairs, and toys.
- Building Insulation: Materials used for thermal insulation in walls, ceilings, and floors.
- Carpets and Rugs: Flame retardants may be applied to carpet fibers or used in carpet padding.
- Curtains and Blinds: Flame retardant treatments are sometimes applied to window coverings.
- Automotive Interiors: Car seats, headrests, and other interior components.
- Mattress Pads and Bedding: Flame retardants may be used in mattress protectors and bedding materials.
- Foam Cushions: Foam used in various applications, such as seat cushions and padding.
- Building Materials: Certain construction materials, such as insulation foam boards and fire-resistant coatings.
How to avoid or find safer Alternative:
- Choose furniture and fabrics labeled “flame retardant-free” or “non-toxic“. Current safety standards allow for fire-safe products without harmful chemicals. Check labels for phrases like “contains flame retardants” and avoid items with strong chemical odors. Look for PBDE-free certifications to ensure safety.
- For furniture look for a “TB117-2013 label” stating item doesn’t have flame retardant.
- Look for plant-based fire retardants treatments usually referred to as intumescent coatings.
- Avoid traditional polyurethane foam-filled products cause these products are more likely to contain flame retardants unless specified.
- Allow off-gassing: If you buy new furniture or products that might contain flame retardants, let them air out in a well-ventilated area before bringing them into your home.
- Use a HEPA vacuum cleaner: Use a vacuum cleaner with a high-efficiency particulate air (HEPA) filter to remove dust and particles that may contain flame retardant chemicals from your living spaces.
Even though PBDEs are banned in the US, manufacturers in countries like China and India still use them in products like strollers. Unfortunately, there’s not enough regulation on imported items, making it hard for parents to know if their child’s gear contains these harmful chemicals. Some manufacturers themselves may not even be sure because different batches can vary.
Right now, there’s no simple way to tell if something has PBDEs without lab testing. If you’re worried about a stroller or other baby items, you can reach out to the manufacturer and ask for an MSDS to see if they’ve tested for PBDEs. Manufacturers should take responsibility for making safe products and ensuring the safety of imported materials.
Although some types like PentaBDE and OctaBDE have been phased out, DecaBDE is still used in things like television casings, even though it is human carcinogen.
- Researchers have developed a non-toxic and effective flame retardant called EDA-DOPO. It is currently undergoing certification and flame tests before it can be available worldwide.
- Oligomeric phosphonate polyol has been identified as a safer alternative to a toxic flame retardant called pentaBDE.
- Scientists at The University of Texas at Austin have created a new flame retardant from a natural compound found in marine mussels. This non-toxic synthetic coating called polydopamine can replace harmful additives used in foam products.
- Plant-based fire retardants are gaining popularity as well. They use natural ingredients like tea leaves and buckwheat to resist fires. These plant-based alternatives are less toxic to humans and the environment because they are made from natural oils, waxes, and resins. They are also effective at extinguishing fires and cost-effective.
- To identify a plant-based fire retardant, look for ingredients such as starch, gypsum, talc, vermiculite, or boric acid on the product label. These are often used in intumescent coatings that form a protective layer during fires. Many plant-based fire retardants are labeled as non-toxic or low VOC.
The use of flame retardants is a complex issue that involves many stakeholders, including manufacturers, regulators, and consumers. Fire retardants are produced by a variety of companies, both large and small. Some of the biggest and most well-known companies that produce fire retardants include Dow Chemical, BASF, and Clariant.
These companies are large and powerful, with significant resources and capabilities. Manufacturers may continue to use flame retardants because they are required by regulations. Regulators may be hesitant to ban flame retardants without first identifying safer alternatives. And consumers are for the most part unaware of the potential risks associated with flame retardants or they may prioritize fire safety over potential health risks.
PFOA & PFAS
what it is
These are different from flame retardants which delay the ignition of fire. They’re synthetic chemicals that are known for being super resistant to things like water, oil, heat, and chemicals. It’s what is put on products and fabric to make them heat, grease, and water resistant.
Two common ones you might have heard of are perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS). These, along with some other chemicals, are part of a bigger group called per- and polyfluoroalkyl substances (PFAS).
Exposure to PFOA and PFOS can occur through various routes, including ingestion of contaminated food and water, inhalation of contaminated air and dust, and dermal contact with consumer products.
These compounds are pretty stubborn and don’t break down easily. Tragically, these nasty chemicals are being released into the air, dumped into the environment, and are polluting our bodies. What’s worse is that they stick around for a long long period of time. They’re building up in our soil and water because they can sneakily spread from where they’re released and contaminate distant areas, even ones that weren’t directly affected.
Where You’ll Find It
- Non-stick Cookware: Often used in the production of non-stick cookware, such as pans and pots coated with Teflon. These compounds can leach into the food when heated at high temperatures.
- Take-out Containers: Some take-out containers, (e.g. food packaging, such as paper and card packaging coated for grease resistance, fast-food wrappers, microwave popcorn bags, pet food bags).
- Draperies: Used in the production of certain draperies and curtains to make them stain-resistant.
- Carpets: Those treated to be stain-resistant or water-repellent. These compounds release into the air, and over time, accumulate in dust or are ingested through direct contact.
- Furniture Items: Furniture items, particularly those treated with stain-resistant or water-repellent coatings. Sofas, chairs, and other upholstered furniture.
- Water Resistant Clothing & Materials: Some clothing items, particularly those marketed as water-resistant or stain-resistant. This is often the case with outdoor gear, such as jackets or pants designed for outdoor activities.
- Personal Care Products: While not as common, perfluorinated compounds can also be found in certain personal care products, such as cosmetics and skincare items.
- Firefighting Foam: Firefighting foam to extinguish petroleum-based fires. However, these compounds contaminate the environment, including water sources.
Health Issues
- Increased cholesterol levels: Associated with elevated cholesterol levels in exposed individuals.
- Thyroid hormone disruption: These compounds can interfere with your thyroid hormones, potentially leading to mood swings or energy issues.
- Immune system effects: Associated with immune system dysregulation, including reduced antibody responses and impaired immune cell function.They weaken your immune system, making it harder for your body to fight off illnesses.
- Birth & Developmental effects: Long-term exposure can have adverse effects on fetal development, including low birth weight, birth defects, developmental delays, and altered immune responses in children.
- Cancer: PFOA has been classified as a possible human carcinogen by the International Agency for Research on Cancer. Evidence suggests a potential link between PFOA and certain types of cancer, including kidney and testicular cancer.
- Impaired liver and kidney function: Interfere with the proper functioning of the liver and kidneys. This can reduce their ability to remove harmful substances from our bodies. Exposure to PFCs has also been linked to liver disease. These compounds can cause liver damage, inflammation, and even contribute to the development of certain types of tumors.
- Oxidative stress and inflammation: PFCs have the potential to induce oxidative stress, inflammation, and cellular damage in the liver. This can further contribute to the development of liver diseases and other related health issues.
- Endocrine disruption: PFCs can disrupt the endocrine system, which regulates hormones in our body. This disruption can lead to hormonal imbalances and negative effects on various bodily functions.
How to avoid or find safer Alternative:

- Labeling: Check for terms like “plant-dyed,” “natural dyes,” or “botanical dyes” on the product tag or description.
Phthalates
what it is
There are 7 different types of plastics, and one of them is called Polyvinyl chloride (PVC). It comes in two forms, hard and flexible. Phthalates, are a group of chemicals often used to make plastics like PVC more flexible, bendable, and soft.
where you'll find it
It is a common plastic often used in furniture, flooring, other household items, wall coverings, and building materials like pipes. It can also be present in some wood finishes and adhesives.
You can be exposed to phthalates in a few other ways:
- Breathing: Phthalates can be found in solvents that release fumes into the air.
- Eating: Phthalates can leach into food from plastic packaging or storage containers, even more when hot food is placed in them.
- Chewing: Some plastic toys for children may have phthalates. If a baby chews on these toys, they can be exposed to the chemicals inside the plastic.
- Touching: Lotions or perfumes stored in plastic bottles can contain phthalates that can be absorbed into your skin.

- Waste and Disposal Issues: Disposal of lead-containing items, like old furniture, can pose environmental challenges. Lead is hazardous and requires special handling to prevent environmental contamination.
- Soil and Water Contamination: Lead from old paint can leach into soil and water, causing long-lasting contamination that affects plant and animal life.
Being aware of lead’s impact can help you take steps to protect your health and the environment, especially when dealing with older or antique furniture.
How to avoid or find safer Alternative:
It is essential to have a professional conduct a lead assessment on your house if it was built before the 1980’s in the U.S. Only in 1978 was such hazardous paint banned in America! Hence, if your house was built before this period, it’s likely to have peeling or chipping lead paint – a serious health risk.
Mercury
what it is
Mercury is an element that can be found in small amounts within the soil and mature waters and is generally not harmful. It can also naturally be found in Earth’s core and is often released by volcanoes, hot springs, and other geological activities.
Sadly, the amount of mercury in our atmosphere has significantly increased due to human-driven combustion from vehicles running on diesel fuel as well as coal-fired power plants and wastewater treatment facilities. When this airborne mercury falls back down to land it then accumulates into bodies of water like lakes or rivers.
After bacteria turn mercury into methyl-mercury, the toxic mixture enters the food chain after small fish consume contaminated bacteria and algae, which then get eaten by bigger fish and birds, until finally humans get exposed to this deadly poison. It’s methyl-mercury that’s dangerous and highly toxic.
where you'll find it
- Thermometers and Thermostats
- Fluorescent, compact fluorescent (CFL), black lights, ultraviolet bulbs, neon bulbs and high intensity discharge (HID) lamps. Mercury containing bulbs display a “Contains Mercury” or “Hg” label with a circle.
- Blood pressure gauges, barometers, and manometers.
- Mercury-contaminated fish and thermostats
- Used in switches, and certain batteries.
health issues
Methyl-mercury damages organs like the brain, kidneys and lungs. Symptoms include tremors, insomnia, memory loss, neuromuscular effects, headaches and cognitive and motor dysfunction. More on that here:
How to avoid or find safer Alternative:
To avoid mercury in household furniture, materials, and home products:
- Use LED or CFL bulbs instead of fluorescent ones, as they don’t contain mercury.
- Check labels and avoid products with mercury switches, like old thermometers or certain electronics.
- Choose mercury-free batteries or rechargeable ones.
- When buying furniture, carpets, or building materials, make sure they are mercury-free.
- Properly dispose of items with mercury, such as old thermometers or fluorescent bulbs, following local guidelines.
- Call the National Response Center (NRC) if you spill more than two tablespoons of mercury.
- Here’s a step-by-step guide on how to clean up a spill less than that.
It’s crucial that people know about the consequences of recklessly discarding mercury-containing items. When we throw away mercury products or wash them down the drain, we add to mercury pollution because it hurts our environment, which then hurts us.
People must check for any traces of mercury in products before discarding them. Each year, broken fluorescent lamps, broken thermostats, dental amalgams, and thermometers add thousands and thousands of pounds of mercury into our soil, water, and air.
There’s something deeply troubling about mercury-containing products that are made but their producers don’t take responsibility for proper disposal. It is incredibly irresponsible of them simply suggesting users about what should be done.
- Disposing such items should be made as convenient as dropping off mail at UPS for example.
- It should be mandated that households and commercial places dispose it properly because not everyone will follow the protocol if they don’t know how serious it is.
- Pick up days for disposed mercury products should also be set up nation-wide just as garbage collection.
For now, this is how to dispose of mercury-containing items
- EPA and health departments or your local waste management agency can guide you for how to dispose of them.
