How are VOCs related to health?

VOCs like benzene, formaldehyde, etc. are carcinogens that cause health problems. Breathing them in can lead to a condition called “Sick Building Syndrome”. The short-term health effects include headache, nausea, acute eye, nose, throat irritation, worsening of asthma or loss of coordination.

What poses a more serious risk to our health is the extended exposure to it. Exposure to VOC concentration found in our day-to-day life takes time for the symptoms to become noticeable, and by that time the damage has already begun. So by ignoring VOCs in your surroundings, we put ourselves at risk for long-term effects such as memory impairment, visual disorders, central nervous system related issues, kidney damage, liver damage, and even cancer. These risks are more adverse for children.

Sources of VOCs:

It's important to understand the sources of VOCs so that we can take measures to reduce our exposure. Here is a list of items that are the most common potential sources of VOC.

Each of these sources releases volatile compounds in the air and the accumulation of these particles becomes more concentrated inside closed spaces due to the collective effect of indoor and outdoor VOCs.

American Cancer Society has classified chemicals like benzene and formaldehyde, which can be found in paint, glue, furniture wax, detergents, thinners, as human carcinogens (Read more here).

How can we reduce VOCs?

You've probably realized by now that most of the products that release VOCs are used regularly in our homes, offices, and children's schools. Studies have found that levels of such compounds average 2 to 5 times higher indoors than outdoors. During and for several hours immediately after certain activities, such as paint stripping, levels may be up to 1,000 times higher than acceptable levels.

Considering the fact that at least some part of our house gets painted once every year or every two years and the various chemical-based household products we regularly use, the accumulation of VOCs can become quite alarming. So what do we do about it? Here are some solutions to ensure that your family isn’t inhaling these toxins.

• Measurement: Even though you can often smell VOCs in the air, sometimes these chemicals might decay over a period of time and you may not smell the strong odor anymore even if VOCs are still present. This is why it is essential to measure their levels at schools, corporate offices, and even at home using a reliable measurement device. You can use the recently launched Airveda monitor PM2510CVTH | to measure VOCs accurately. Learn more about our VOC measuring monitor here. | TVOC (total volatile organic compounds) in the air is measured in ppb (parts per billion) or µg/m³ (micrograms per cubic meter). TVOC levels up to 325 ppb in indoor spaces are acceptable, but one must take the following precautions if the levels are higher.

• Controlling the source: It is crucial to eliminate sources of VOCs to minimize your exposure.

  • While purchasing any chemical-based products: detergents, deodorants, air fresheners, adhesives, etc., choose a product that doesn’t contain large quantities of harmful chemicals such as formaldehyde, benzene, methylene chloride, perchloroethylene, chlorofluorocarbons.
  • When buying new furniture and mattresses, allow them to off-gas before bringing them into the house.
  • Encourage schools and offices to purify the air after furnishing or install monitors and purifiers after big renovations for initial years since off-gassing can go on for longer in such cases.
  • Don’t overuse products like sprays, dyes, lubricants, etc.
  • Do not unnecessarily store large amounts of such chemical-based products in the house to prevent leaks and make sure you follow directions (how and how much to use) on their labels.
  • Avoid using plastic containers near the stove or in the microwave. Even if the plastic is graded microwave safe, heating can still cause them to release these toxins.

• Regular ventilation: The easiest way to deal with VOCs at home is to open the windows and let fresh air flush in to avoid excess accumulation indoors. Offices and other larger buildings should set up automatic demand-controlled ventilation systems to ensure that buildings can be ventilated when VOC concentrations inside are high.

• Air Purification: Air purifiers equipped with activated carbon filters are an effective way to reduce the concentration of VOCs in indoor air, in particular in locations where ventilation with outside air is not possible.

We hope that this article has helped you learn about VOCs and urge you to start noticing smells and measuring VOCs to ensure cleaner air in your homes, offices, and children's schools. Sometimes they smell, sometimes they don’t. But they are always harming you.
