Pollutants in the air – causes & effects

Especially in closed rooms such as B. the office or the apartment accumulate numerous pollutants. These gaseous substances are invisible, but they can have serious health effects. The sick building syndrome, also known as building sickness, describes a pathological condition of people that only manifests itself when they are in a certain building or room. When that person leaves the building, the symptoms go away. Those affected often have general well-being complaints and complain of tiredness, insomnia or lack of concentration. The causes of the building sickness can be traced back to a high level of pollutants in the air.

The most common indoor pollutants

Everyone probably knows that car exhaust fumes and cigarette smoke contain pollutants. But you probably didn’t realize that there were poisons in furniture or cosmetic products. In the following, you will find out what the most common indoor pollutants are, what causes pollutants in the air and what effects they have on health.

  • Formaldehyde: This pollutant is most commonly found indoors. It comes into the home from car exhaust, cigarette smoke or from using a gas stove. In addition, some textiles, adhesives or disinfectants contain formaldehyde. The health consequences of formaldehyde are irritation of the mucous membranes, eye irritation, headaches or disorders such as insomnia or nervousness.
  • Benzene: Benzene is a hydrocarbon and can be found in vehicle exhaust and in cigarette smoke. It also arises during combustion processes, e.g. by using a fireplace. Apartments near garages or petrol stations or on busy streets have particularly high benzene levels. A high intake of benzene can lead to changes in the blood count and cause symptoms such as tiredness, weakness, dizziness or palpitations.
  • Xylene: Xylene is found in paints, dyes, rubber and pesticides. It is harmful to human health if it is absorbed through the skin or the respiratory tract. Effects are e.g. Memory and orientation disorders, dizziness, headache or shortness of breath.
  • Polyethylene: This pollutant, also known as polyethylene, is particularly common in cleaning agents. Inhaling it can irritate the airways and cause symptoms such as dizziness, headache or drowsiness.

Indoor plants as pollutants killers

Now you are probably wondering how you can get these pollutants out of your home. The solution: air-purifying indoor plants! We owe this discovery to NASA. Their experts wanted to find out how they can improve the polluted air in space stations. The result of their study showed that certain plants can filter pollutants from the air. For example, the green lily was able to reduce the level of formaldehyde in the room by 86% in one day.

So, in addition to a good ventilation system, plants are a great help in removing pollutants. The green air fresheners not only convert CO2 into oxygen, but are also able to filter pollutants from the air. Rooms that are not often ventilated or that are not well ventilated benefit from air-purifying plants. These dramatically reduce the health risk from polluted air.

Pollutants in the apartment: what to do if the air is bad?

We humans spend most of our time in closed rooms, if there is insufficient exchange of indoor and outdoor air, the air is thick. Furniture, carpets and other floor coverings in particular, as well as paints, varnishes, cleaning agents and electrical appliances emit unhealthy substances that collect in the air in the room.

If too many pollutants such as ammonia, benzene, formaldehyde, trichlorethylene or xylenes occur, this can have an impact on our health. Headache, tiredness, nausea and irritation of the mucous membranes are just a few of the possible consequences. Bad air in the bedroom also affects our sleep. Fortunately, regular ventilation and air-purifying plants improve the indoor climate in the long term.

How do plants filter pollutants from the air?

Can’t imagine how plants can filter toxic pollutants from the air and convert them into healthy oxygen? It sounds too good to be true – but the inconspicuous plants really can! The plants absorb the pollutants through small stomata in the leaves. Via the transport system, the pollutants are released through the roots into the earth, where they are ultimately broken down and eaten by microorganisms. The roots of the plant also have the ability to absorb pollutants directly from the air and convert them into nutrients such as glucose.
