Personal Exposure and Ambient Measurement of "Chlorine Dioxide" Used as a Biocidal Product in Indoor Air

Chlorine Dioxide Measurement

WHAT IS CHLORINE DIOXIDE?
Chlorine dioxide is an oxidant that has been used as a disinfectant since the 1900s. It is a very effective and long-lasting disinfectant in destroying fungi, algae, microbes, viruses and pathogens by weakening their molecular bonds. Chlorine dioxide is effective in a wide pH range. The active solution maintains its effectiveness for about 12 months if it is stored in a cool and dark place.

WHICH DISINFECTIONS IS USED?
Its good compatibility with the environment makes it possible to use it without hesitation in all kinds of water conditioning. Chlorine dioxide is used as a disinfectant in many sectors such as agriculture, animal husbandry, health institutions, waste water treatment systems, hotels, pools, industry, beverage sector.

WHAT ARE THE ADVANTAGES?
Chlorine dioxide is an excellent bactericide (E.coli), spore killer, virus killer, algae killer. Compared to other disinfectants (Paracetic Acid, Hydrogen Peroxide, Sodium Hypochlorite), it provides 2.5 times more oxidation power at a certain pH range and requires less labor. It provides a stronger and faster disinfection effect compared to chlorine. It removes microbiological residue in pipes and membranes. It kills the biofilm and prevents its re-formation. It does not cause odor and taste problems caused by phenols, algae and their by-products by breaking down, and also destroys existing ones. It prevents the formation of harmful by-products such as trihalomethane, chlorphenol, AOX and chloramine.

WHY SHOULD MEASURE IN THE ENVIRONMENT?
It is stated in the World Health Organization's "Concise International Chemical Assessment Document 37" that the 8-hour average of all personal air exposure should not exceed 0.1 ppm (0.28 mg / m3), due to the toxic effect of chlorine dioxide on breathing.
< br> After the mixture of components / precursors that will form chlorine dioxide is provided or the reaction starts; The chlorine dioxide formed is continuously emitting and there is no system that can be stopped. For this reason, it is obligatory to document with analysis reports that the chlorine dioxide concentration in the indoor air does not exceed 0.1 ppm according to the area / volume recommended by the manufacturer for use until the end of the product's application life.

In order for chlorine dioxide produced with components or precursors to be used as a disinfectant in the field of public health, it is obligatory to obtain a biocidal product license from the "Ministry of Health" according to the "Biocidal Products Regulation".
Chlorine Dioxide measurements and analyzes in our laboratory are carried out in all facilities accredited by TÜRKAK and with the ministry authorization of the Ministry of Family, Labor and Social Services (İSGÜM) based on the "ASTM D 4490" method.
