I want to check TBC and Yeast & mould for Indoor air quality. Kindly suggest me any international standard method not research paper?
Thanking you
indoor air contaminants and their main sources:
1.Carbon dioxide (CO2), tobacco smoke, perfume, body odours – from building occupants.
2. Dust, fibreglass, asbestos, gases, including formaldehyde – from building materials.
3. Toxic vapours, volatile organic compounds (VOCs) – from workplace cleansers, solvents, pesticides, disinfectants, glues.
4.Gases, vapours, odours – off-gas emissions from furniture, carpets, and paints.
5.Dust mites – from carpets, fabric, foam chair cushions.
6.Microbial contaminants, fungi, moulds, bacteria – from damp areas, stagnant water and condensate pans.
7.Ozone – from photocopiers, electric motors, electrostatic air cleaners.
Several organizations* have published recommended guidelines for indoor air quality. For example, the Government of Canada has prepared a number of publications on air quality. In the United States, the Occupational Safety and Health Administration (OSHA) has compiled information on Indoor Air Quality.
In addition, IAQ is implied in most building codes as design and operation criteria. Building codes in Canada and the U.S. generally refer to the American Society of Heating, Refrigerating, and Air Conditioning Engineers* (ASHRAE) Standard 62.1-2010 - Ventilation for Acceptable Indoor Air Quality (or previous versions), or other acceptable standards.

Dear Pouneh Shahrouz Ebrahimi,
Thank you for your prompt response.
I hope you are doing well.
Actually I am interested to conduct TBC and Yeast & Mould in Indoor Air. So just i am asking which international method may refer here. If you have soft copy please provide me.

Methods for assessing microbial constituents
Constituents or metabolites of microorganisms can be measured to estimate microbial exposure, instead of counting culturable or non-culturable microbial propagules.
Toxic (e.g mycotoxins) or pro-inflammatory components (e.g en-dotoxins) can be measured, and non-toxic molecules can be used as markers of large groups of microorganisms or of specific microbial genera or species. PCR techniques are available for the identification of species of bacteria and fungi in air and several quantitative PCR methods have been validated for use in the indoor environment.you can read here in WHO guidelines page 42.

Dear Anand,
the Association of German Engineers is involved in international standardization (ISO) related to microbial IAQ (see attached links).
There are ISO Standards on sampling of moulds by filtration (ISO 16000-16), cultivation procedures (ISO 16000-17), sampling of moulds by impaction (ISO 16000-18), sampling strategy for moulds (ISO 16000-19), total spore count (ISO 16000-20), sampling from materials (ISO 16000-21), test chamber method for the reduction of airborne bacteria (ISO 16000-36).
Best,
Sascha
