VOCs in Your Home: Sources, Effects & How to Reduce Them?

Volatile Organic Compounds a.k.a VOCs are a group of chemicals, commonly found in many the construction materials and home maintenance products. These toxins are discharged into the indoor air we breathe once they reach our homes.

They may or may not be adorable, and odour is not a reliable signal of health risk. Examples of these chemicals include:

-          Benzene

-          Ethylene Glycol

-          Formaldehyde

-          Methylene Chloride

-          Tetrachloroethylene

-          Toluene

-          Xylene

-          Butadiene, etc.

VOCs in wastewater and air has proven to be highly dangerous for human health. But where do they originate? What impact do they have on us? What can we do to make their presence in our lives less noticeable? Here's a quick rundown to assist you to figure out the answers to some crucial VOC-related concerns.

Major Sources of VOCs

Building materials, home and personal care items, and several other everyday activities are major sources of VOCs. E.g.

• Paints, varnishes, caulks, adhesives, carpet, vinyl flooring, composite wood products, upholstery, foam, and other building materials are all substantial emitters of VOCs.

• Air fresheners, cleaning products, cosmetics, motor oil, gasoline, and other home and personal care goods emit large amounts of VOCs.

• Daily activities such as smoking, dry cleaning, photocopiers, cooking, and wood-burning are major VOC emitters.

VOC Exposure: Effects on Health

Inhaling any chemical might cause health problems depending on how much is in the air, how long and how often a person breathes it in.

Even long-term / continuous exposure to lower levels of VOCs may raise health concerns in people with lower immunity. Studies have shown that continuous exposure to VOC in air quality may generate problems in patients with asthma or someone sensitive to chemicals.

It's vital to realise that VOCs are a collection of compounds. Each chemical has its toxicity and can cause severe health issues.

Common symptoms of VOC exposure in case of Acute & short term exposures (E.g. hours to days):

· Irritation in eyes, nose & throat

· Constant headache

· Feeling nausea or vomiting

· Sense of dizziness

· Worsening of asthma symptoms

Common health affects of VOC exposure in case of Chronic exposures (E.g. For years to a lifetime):

· Developing Cancer in organs

· Organ Damage like liver & kidney

· Damage to the central nervous system

What is a safe VOC level?

It is best to restrict your exposure to VOC-containing goods and materials to protect your health. If you believe VOCs are causing health concerns, try lowering the amount in your house. In case you have symptoms, it’s better to see a doctor and rule out other reasons causing the problem.

Most researchers in analytical labs emphasised on specific substance research. The health effects of chemical mixtures are less well understood. There are no health-based criteria for group of VOCs. It’s because the toxicity of each molecule differs and hence has individual impacts.

Are some persons more vulnerable to VOC exposure than others?

Involvement of VOCs in air quality can cause irritation and disease in persons with respiratory disorders such as asthma, small children, the elderly, and those who have heightened chemical sensitivity.

How can I lower the amount of VOCs in my home?

Here are some important things to keep in mind to lowering the risk of VOCs presence in your home:

• When it comes to paints, solvents, adhesives, and caulks, buy only what you need at the moment because unused household chemicals can may leak and release VOCs into your indoor air.

• Keep unneeded chemicals in a garage or shed where they won't be seen.

• Get rid of any unused chemicals you have in your home or garage.

• Look for floor models that have been allowed to off-gas in the store when buying new things, as well as low-VOC paints and furnishings.

• Increasing the amount of fresh air in your home can help to lower VOC levels indoors.

• High temperatures and humidity causes higher gaseous emissions from chemicals. So, it’s highly suggested to maintain a lower temperature and relative humidity inside your home to avoid VOCV release.

• When possible, execute home renovations when the house is empty or during seasons when you can open doors and windows for better ventilation.

To detect the presence of VOCs in Wastewater and air quality, Imspex has developed a device. It uses GC-IMS technology to detect and identify the quantum and quality of VOCs in air & water and tell you how safe it is. The device has greater industrial applications and will play a major role in improving the quality of air and water in and around our houses in the coming future.

Dual Range Portable Balance 22/52  gx 0.0002/0.001mg, Ext. Cal, 1EA

The EJ-54D2, a dual range model, has two weighing ranges with different capacities and readabilities, each range extending from zero to its capacity.

The readability of the lower capacity (22 g) range is as fine as 0.0002 g (or 0.001 ct), which, for example, is ideally suited for precisely weighing/ counting small pieces of precious metals/jewelries

A quality rubber product testing service

Rubbers are important raw materials used for various purposes. They are constantly used in constructing of materials, housewares and many other industrial parts. They are majorly used in automobile industry for making of tyre with various designs and shapes. The usage of rubber goes countless in numbers in the market. However, before the finished products of rubber are launched in the market, they are to be tested and examined ensuring they do not pose risk or any hazard to users.

Here comes the role of rubber product testing that identifies the mechanical properties, flexibility and elasticity of the products. During the product formation process, several other chemicals are used and many other mechanical processes are applied which are to be maintained under specific guidelines of the Government. Therefore, it has become essential to measure the properties of the products, thus helping in identifying the quality that determines the usage of the products.

So, for any new rubber product, the companies introducing it are required to test their products from the verified testing agency or laboratories with all the essential standard equipment’s and expert professionals as per the guidelines of the Government. Those professionals will be able to investigate the rubber compounds for manufacturers, distributors, and designers and also the installation and equipment constructors too.

When it comes to the, there are number of companies in the market. However, before choosing the right one, it is important to identify the right one through different measures. For instance, the right choice will be the one that has been in the market for many years serving the clients.
