WHAT IS FORMALDEHYDE DANGEROUS?
Frequent headaches and feeling sick after recent repairs? Instead of feeling new, clean and fresh, fatigue and apathy come on? This is not a vitamin deficiency, it is very likely that this formaldehyde is released from freshly laminated floors, a stretch ceiling, and newly purchased furniture ...
Formaldehyde causes irritation of the mucous membranes and can lead to the development of allergic reactions, however, it is an immediate health hazard only when ingested or with prolonged exposure in high concentrations.
Of course, there may be other causes of poor health, but to verify this and determine the source of formaldehyde, it is better to conduct an analysis to determine the formaldehyde in the air.
SOURCES OF FORMALDEHYDE IN AN APARTMENT AND AT ATMOSPHERIC AIR
It is rather difficult to determine the source of formaldehyde in an apartment (except for tobacco smoke) - most modern furniture and many finishing materials are made using phenol-formaldehyde resins. Such materials can release formaldehyde for a long time, constantly poisoning the air in the room.
The main sources of formaldehyde in outdoor air are transport, industrial enterprises, and ... natural photochemical processes in the atmosphere.
MPC FORMALDEHYDE IN AIR
In atmospheric air, residential and public premises, MPC of formaldehyde is defined at the level of 0.05 mg / m3 (maximum one-time) and 0.01 mg / m3 (average daily). For working area air in enterprises where formaldehyde can be released in the process, the maximum permissible concentration is much higher - 0.5 mg / m3
SAMPLES SELECTION FOR FORMALDEHYDE IN AIR
Laboratory specialists conduct sampling in absorbing solutions for formaldehyde analysis at locations agreed with you.
The time taken to take one sample depends on the expected concentration, but, on average, does not exceed 30 minutes.
The choice of sampling points for determining formaldehyde depends on the purpose of the study: if the analysis for formaldehyde is carried out in order to make sure that its concentration does not exceed the allowable values, it is enough to choose one point located in the center of the room, usually in the people’s breathing zone. In the case where the analysis is performed to determine the source of formaldehyde in the room, we recommend sampling in the center of the room and near potential sources. Then, according to the difference in the concentration of formaldehyde in the selected samples, in some cases it is possible to draw conclusions about what is the most intense source of formaldehyde emission.
HOW A FORMALDEHYDE IN AIR IS DETERMINED
The determination of formaldehyde in the air is carried out according to several different methods.
Our laboratory applies in each case that formaldehyde method that best suits specific conditions - photometric methods are better suited for determining formaldehyde in relatively high concentrations in working area air, and the fluorimetric method for determining formaldehyde for atmospheric air and residential and public air. buildings. The choice of methods for determining formaldehyde does not affect the cost of analysis.
After receipt in the laboratory, the selected samples are recorded and transferred for analysis.
