For those who are building a new house or are in the process of decorating and renovating the house, Of course, the problems encountered are dust and the pungent smell of various chemicals. This dust and smell is dangerous to health. It can cause respiratory disease, asthma, allergies, or lead to the greatest danger of acute heart attack and cancer.
For the matter of dust, Many of you may already know the dangers of dust. Today, the admin would like to share information about The dangers of chemical odors that make our noses hurt.
A newly built house You will find that there is a pungent smell that stings your nose. which these smells Part of it comes from two dangerous substances:
First, what is formaldehyde?
Formaldehyde (Formaldehyde) is a chemical that is a starting material in many manufacturing industries. which the International Organization for Research on Cancer (International Agency for Research on Cancer; IARC) assessed it is a Group 1 carcinogen that can cause cancer in humans, namely nasal cancer.
Most formaldehyde in residences is released from home decoration items such as crockery, furniture, sofa cushion covers, home wall paint, and houses that use lacquer to coat wooden floors. Antifungal agents, carpets, bedsheets, etc. The factors that cause formaldehyde to be released from furniture are temperature and insufficient ventilation. When the room temperature exceeds 26 °C, the concentration of formaldehyde will increase. And if the room does not have a ventilation system It will cause the concentration of formaldehyde to increase as well. But if you open the window to ventilate for 1 hour, the concentration of formaldehyde can be reduced as well.
From such factors, If residents are exposed to formaldehyde higher than 0.1 ppm, it will cause eye irritation. Nose and respiratory tract symptoms may include coughing, chest pain, and shortness of breath, but if the concentration is higher than 100 ppm it may cause unconsciousness. and finally dies Because at high concentrations Formalin is transformed into formic acid, which has the effect of destroying the functioning of various cells in the body if given in small amounts over a long period. It will cause negative effects on various systems of the body or cause cancer.
The second is what are volatile organic compounds?
Volatile organic compounds commonly known as VOCs, come from the term Volatile Organic Compounds, which refers to a group of organic compounds that easily evaporate. Can be dispersed into the air at normal temperature and pressure. which this volatile organic compound in the atmosphere is classified as toxic air (Toxic Air). In our daily lives, we get this substance from many products such as house paints, cigarette smoke, bleaching liquids, dry cleaning liquids, and hair dyeing and perming liquids. Pesticides are Substances that result from combustion and contaminate the air, food, and drinks. This harms the health of the recipient, namely, it is a carcinogen. and affects the respiratory system Symptoms include dizziness, headache, watery eyes, sneezing, sore throat, shortness of breath, palpitations, nausea, fatigue, loss of consciousness, and even death.
How to prevent and reduce formaldehyde and volatile organic compounds?
Open the window to ventilate for about 1 hour to reduce the concentration of formaldehyde.
Install a ventilation system or choose to use an air purifier. Effective in absorbing and eliminating various chemicals. Activated carbon (Activated Carbon) because activated carbon is a material that can trap odor-causing vapors very well. Including eliminating and decomposing toxins using technology. Photocatalytic oxidation, which is a process of intensive oxidation of hydroxyl, works under UV light, which can eliminate bacteria and viruses, and can degrade formaldehyde, volatile substances, and odors.
** Solving the problem of volatile organic compounds may be done by destroying VOCs, such as chemically by using ozone and hydrogen peroxide gas. and other oxidizing substances Or in biology, use microorganisms that are effective in degrading them **
