Stale Air, odours, humidity and damp problems Costa del Sol. 

Many surveys we undertake are due to a foul smelling odour or stale air.

Odours are a symptom of a problem which is normally due to the sanitation pipe works.  Bacteria builds up within the pipework creating gasses, these gases percolate up through the system venting out through the bathroom WC, water basins and shower units.

The gases displace the water in the traps, creating a vacuum which draws more gases into the room and so it continues.

We must remember that a strong odour is basically bacteria or chemical loaded air and if not attended too, will develop into a mould infestation.  The gases are bad for your health with symptoms resulting in a dry or sore throat, also affecting eyes and nose.  In many cases it is TVOS gas that is the problem.

How TVOC affects indoor air quality & effects on wellbeing and health

When we think of air quality, people mostly think of the outside world, smog from cars and industry or the fresh air of woods. However, 90% of our daily life is spent indoors: our home, workplace, public buildings and schools. Indoor quality is one of the most important components of well-being, feeling comfortable in a room.  Besides, bad air quality has implications on your productivity and may even harm your health. The Volatile organic components (VOC) may be the least known.

TVOCS affects the wellbeing, feeling comfortable and health

TVOCs affect your sense off wellbeing.  Some VOC’s are bad for health. Some VOCs are more harmful than others. Whether a  TVOC is harmful, depend on factors as level of exposure and length of time being exposed. Besides, some people -especially children and elderly people- have a higher sensibility then others. Immediate symptoms that some people have experienced soon after exposure to VOCs are eye and respiratory tract irritation, headaches, dizziness, visual disorders and memory impairment. An example: some people get immediately a headache from being in a room which is just painted. Others may find the smell just uncomfortable.

TVOCs can cause:

  • Headaches

  • Dizziness

  • Nausea

  • Eye, nose, and throat irritation

  • Coordination loss

  • Fatigue

  • Some VOC’s (as toluene) cause irritation at normal levels, eg allergic skin reactions

  • Bad odour and stale air are uncomfortable and affect people’s feeling of cleanliness

  • Some VOC’s as formaldehyde can cause cancer. VOC’s for a long-term exposure in large doses can damage liver, nervous system and kidneys

What is TVOC?

What is TVOC? TVOC means Total Volatile Organic compounds. Volatile organic compounds are organic chemicals that become a gas at room temperature. There are thousands of VOCs and a multiple of VOC’s are at the same time present. Therefore, the Total VOC is used at most times: measuring the concentration of the total of VOC’s This is easier and less expensive then measuring individual VOC’s.

Some examples of VOC’s are:

  • Bacteria gas's

  • organic gas's

  • Sanitation gas's

  • Benzene

  • Ethylene glycol

  • Formaldehyde

  • Methylene chloride

  • Toluene

VOC in Products

Many VOC’s come from:

  • Cleaners and disinfectants

  • Pesticides

  • Air fresheners

  • Paints and solvents

  • Glue

  • New furniture and carpets

  • Construction materials

  • Electronic devices

  • Plywood

So, some VOC’s may come from everyday life, especially found in sprays and aerosols from cleaners and such. Besides, new construction and renovation may cause significant health concerns. Construction materials, but also the new furniture, carpets and plywood may increase the indoor concentration of VOC’s due to off-gassing. Until the off-gassing has declined, those new products may cause serious threats to your well-being. You can be a polluter yourself, however often far less dangerous then products do.

VOC in the outside world

Vehicle exhaust and industry pollution may also cause bad indoor air quality when the polluted air can enter the building due to open windows or air condition that doesn’t work properly. Especially when the building stands in congested or industrial areas.

Are all VOC’s harmful?

“EPA’s Total Exposure Assessment Methodology (TEAM) studies found levels of about a dozen common organic pollutants to be 2 to 5 times higher inside homes than outside, regardless of whether the homes were located in rural or highly industrial areas. Additional TEAM studies indicate that while people are using products containing organic chemicals, they can expose themselves and others to very high pollutant levels, and elevated concentrations can persist in the air long after the activity is completed.

TVOC can be measured in micrograms per cubic meter (µg/m3) of air (or milligrams per cubic meter (mg/m3), parts per million (ppm) or parts per billion (ppb)). The table below shows that less than 0.3 mg/m3 are considered low TVOC concentration levels. And levels between 0.3 mg/m3 to 0.5 mg/m3 are acceptable.
