Indoor Air Quality Analysis and Investigation

You want to assess the exposure of your employees to contaminants. An incident occurred and you want to ensure that your environment is not hazardous to your workers Enviro-option is a professional company that assists you in diagnosing indoor air quality for your health and safety measures at work. 

We produce samples according to the procedures described in standards and regulations. The analysis results are interpreted and compared with reference values to assess the quality of indoor air.

We can support your service Health Safety Environment and provide you with a comprehensive and detailed report on measurements made on the site in the context of industrial hygiene.

Enviro-option can offer the following air tests :

  • Gélose

Search microbiological contaminants :

  • Molds
  • Bacteria (legionella)

Search physical contaminants :

  • Asbestos
  • Total dust
  • Respirable fibers
  • Silica
  • Metals

Search chimical contaminants :

Comfort parameters :

  • Relative humidity
  • Temperature
  • Audience measurement


It can exist in many forms including the form of crystal that is associated with respiratory health problems: silicosis (notifiable disease by the LSP). It is found in several sectors including manufacturing or handling of building materials (eg concrete).

Exposure to crystalline silica as quartz in the workplace is primarily powders or dust in the breathing zone of the employee. The rate of crystalline silica may vary depending on the material in which it is located. Preventive measures aim to minimize worker exposure to crystalline silica as quartz information, methods of work, the mastery of the product and ventilation, etc..

VOC (Volatile organic Compunds)

According to Environment Canada, VOCs are organic compounds containing one or more carbon atoms, high vapor pressure, and therefore easily evaporate into the atmosphere. There are thousands of compounds that fit this definition, but most programs are focused on the 50 to 150 most abundant compounds containing two to twelve carbon atoms.

According MDDEFP, Volatile Organic Compounds (VOCs) are substances formed of at least one carbon atom and a hydrogen. They are found in the gaseous state in the atmosphere. Several of these compounds participate in photochemical reactions responsible for the formation of tropospheric ozone. Others, such as formaldehyde and PAHs (Polycyclic Aromatic Hydrocarbons), are also considered toxic and can affect the health of the population.


It is a colorless gas with a characteristic odor. there are many sources of formaldehyde inside a building because many consumer products contain (paper, cosmetics, detergents, furniture, wood, carpets, tobacco smoke, UFFI ...).

Hexavalent chromium

Activities welding, cutting , mixing and thermal spraying is carried in many industries. Due to the high temperatures reached the melting point fumes are emitted and can be inhaled by operators or persons in the vicinity. These fumes are composed mainly of gas and solid metal particles with hexavalent Chromium .

The inhalation of air containing high concentrations of chromium causes respiratory damage and induces cancers.

This is why prevention measures must be implemented. Act on health and safety at work aims to eliminate hazards at the source . When engineering measures and changes in working methods are not sufficient to reduce exposure to this substance , wearing personal protective equipment may be necessary . Protective equipment must comply with the regulations.
