Household Cleaners: Toxic Chemicals Lurking In Your Home

what pollutants are in indoor house cleaning prodcuts

The air inside our homes is often more polluted than the air outdoors, and household cleaning products are a significant contributor to this. Many cleaning products contain volatile organic compounds (VOCs) such as acetone, methanol, and glycols, which can evaporate easily and be inhaled, triggering allergies and irritating the eyes, nose, and throat. Inhalation of VOCs can also disrupt the endocrine system and potentially increase cancer risk. To improve indoor air quality, it is recommended to use fewer products with fewer chemicals, improve ventilation, and use air purifiers or plants to absorb toxins and pollutants.

Volatile organic compounds (VOCs)

Some common VOCs include formaldehyde, acetone, methanol, glycols, methylene chloride, ethanol, and dichloromethane. Formaldehyde, for instance, is found in cosmetic and household products as a preservative. These compounds are emitted by a wide array of products, and concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors.

The potential health impacts of VOCs are varied. Once inhaled, they can irritate the eyes, nose, and throat, and too much irritation can inflame and damage the airway, potentially resulting in breathing issues and higher asthma rates. They can also disrupt the endocrine system by mimicking the activity of hormones, potentially increasing the risk of cancer. Some organics are known to cause cancer in humans, and abnormal concentrations of VOCs may indicate disease progression for conditions like asthma and cancer.

To reduce exposure to VOCs, it is recommended to increase ventilation when using products that emit them, follow label precautions, and avoid storing opened containers of unused paints and similar materials.

Allergens and respiratory issues

The air inside our homes is more polluted than the air outdoors, and household cleaning products are a contributing factor. Many cleaning products contain volatile organic compounds (VOCs), such as acetone, methanol, and glycols like 2-butoxyethanol. These chemicals evaporate easily and can be inhaled, triggering allergic reactions and irritating the eyes, nose, and throat. This irritation can lead to inflammation and damage to the airway, resulting in respiratory issues such as asthma and potentially chronic obstructive pulmonary disease (COPD). Studies have found higher asthma rates in professional cleaners and even in individuals exposed to these irritants as infrequently as once per week. There is also an observed association with lung weakness.

VOCs can also have systemic effects beyond the respiratory system. Once inhaled, they can disrupt the endocrine system by mimicking hormone activity, potentially increasing the risk of cancer. While research has found higher cancer rates among cleaning professionals, the same link has not been established for casual household users. However, it is important to note that overexposure can occur through large doses of harsh disinfectants or frequent use of smaller amounts over an extended period.

To mitigate the risks associated with indoor allergens and respiratory issues, there are several strategies to improve indoor air quality. One approach is to increase natural ventilation by opening windows and doors and using fans to bring in more outdoor air. This simple method can effectively reduce the concentration of indoor air pollutants. Additionally, local exhaust fans in the kitchen and bathroom can directly remove contaminants from these rooms while also increasing the overall ventilation rate. It is crucial to combine ventilation with source control, such as adjusting emissions from gas stoves or sealing off sources like asbestos.

Another way to enhance indoor air quality is by using air purifiers. These devices can address a broad spectrum of airborne pollutants, including dust, pollen, pet dander, mould spores, and even airborne pathogens. Air purifiers are especially beneficial for individuals with respiratory conditions, as they mitigate triggers and improve symptoms. Portable air purifiers, when sized and placed correctly, can effectively reduce airborne contaminants.

For a natural and aesthetically pleasing alternative to air purifiers, certain flowers and houseplants can improve indoor air quality. According to a 1989 NASA study, specific varieties of flowers and plants can absorb toxins and pollutants, such as formaldehyde, ammonia, and benzene, while also increasing humidity levels by releasing moisture into the air. Examples of recommended flowers include peace lilies, orchids, and lavender. These flowers not only enhance the indoor environment but also actively contribute to cleaner air.

Harmful chemicals and toxins

The use of toxic cleaning products can be harmful to health. In 2023, the nonprofit Environmental Working Group found that 30 common cleaning products contained 193 hazardous chemicals. Many of these are volatile organic compounds (VOCs), such as acetone, methanol, and glycols like 2-butoxyethanol. These compounds evaporate easily and can be inhaled, triggering allergic reactions and irritating the eyes, nose, and throat. This irritation can inflame and damage airways, potentially leading to breathing issues and higher asthma rates. There is also a potential link to lung weakness and an increased risk of developing chronic obstructive pulmonary disease (COPD).

The impact of these pollutants goes beyond the respiratory system. Once inhaled, VOCs can disrupt the endocrine system by mimicking hormones, potentially increasing cancer risk. Overexposure can have rapid and severe health consequences. To protect yourself, it is recommended to use fewer products to limit exposure to multiple chemicals.

To improve indoor air quality and reduce the concentration of pollutants, increasing outdoor ventilation is advised. Opening windows and doors, using fans, and running air conditioners with open vents can help bring in fresh air and remove contaminants. Additionally, air purifiers can be used to address a broad spectrum of airborne pollutants, including VOCs.

Some natural alternatives to air purifiers include certain flowers and plants, such as peace lilies, orchids, and lavender. These plants can absorb toxins and pollutants like formaldehyde, benzene, trichloroethylene, xylene, and toluene, while also increasing humidity and improving indoor air quality.

Air purifiers and natural alternatives

Air purifiers are a good option to improve indoor air quality and mitigate triggers for respiratory conditions. They are particularly useful if you live in an area with high outdoor pollution, in a home with limited ventilation, or with pets.

When choosing an air purifier, consider the room size, certifications, ratings, and filters. Look for purifiers with true HEPA filters, which capture at least 99.97% of airborne particles of a 0.3-micron diameter in a single pass. Some purifiers also have additional carbon or charcoal filters that can help with VOCs. Smart air purifiers offer real-time data on indoor air quality and allow for operation scheduling. However, be aware that some purifiers with ionizers may produce a small amount of harmful ozone.

If you're looking for natural alternatives to traditional cleaning products, you can make your own using ingredients like vinegar, water, and essential oils. Baking soda is another powerful natural cleaning agent, great for scrubbing and removing odours. Coconut oil can be used to polish wooden furniture and condition leather sofas. For windows, mirrors, and screens, a mixture of water, alcohol, and white vinegar will leave them streak-free. Natural alternatives are a step towards sustainable living, reducing packaging waste and limiting the flow of pollutants into waterways. They are also cost-effective and allow you to customise the scent of your cleaning products.

It's important to read the labels on cleaning products and choose those with reduced amounts of VOCs, fragrances, irritants, and flammable ingredients. Warm water and soap can often be effective for cleaning, especially at home. Additionally, the U.S. Environmental Protection Agency has a list of products that meet its Safer Choice requirements, providing safer alternatives for cleaning.

Health risks and long-term effects

The use of indoor house cleaning products can have a range of health risks and long-term effects. Studies have shown that the air inside homes is often more polluted than the air outdoors, with toxins stemming from household cleaners.

One of the main health risks associated with indoor cleaning products is the presence of volatile organic compounds (VOCs). These compounds, such as acetone, methanol, benzene, formaldehyde, glycols, and 2-butoxyethanol, can easily evaporate into the air and be inhaled, triggering allergic reactions and irritating the eyes, nose, and throat. Prolonged exposure to these irritants can lead to airway inflammation and damage, resulting in breathing issues and potentially contributing to higher asthma rates and lung weakness.

The impact of VOCs goes beyond the respiratory system. Once inhaled, these compounds can disrupt the endocrine system by mimicking hormone activity, potentially increasing the risk of cancer. Research has indicated higher cancer rates among cleaning professionals, although the link is less clear for casual household users. Overexposure to harsh disinfectants can have rapid or gradual detrimental effects, depending on the frequency and duration of use.

In addition to VOCs, other pollutants released by cleaning products include formaldehyde, benzene, and trichloroethylene. These chemicals can be absorbed by carpets and other household items, contributing to long-term indoor air pollution.

The use of non-stick cookware with Teflon coating can release toxic fumes known as perfluorinated compounds (PFCs), leading to flu-like symptoms and potentially having long-term health impacts. PFCs are persistent pollutants that can accumulate in the body over time.

To mitigate these health risks, it is important to carefully read product labels and avoid cleaning products containing harmful ingredients such as PEGs, sulfates, chlorine phthalates, parabens, artificial fragrances, BHA & BHT, polyethylene glycol, phenols, triclosan, 2-Butoxyethanol, and ammonia.
