  • The samples are treated by experts in the confines of a laboratory accredited to ISO 17025;
  • All sampling methods comply with the standards and regulations of the Health Research Institute and safety of Quebec (IRSST) and the Health and Safety Regulations of work, and Health Canada;
  • All collected samples were analyzed in the laboratory by microbiologists or by professional chemists whose services are charged with the connection between their specific skills and the nature of work to be done.

Our technical services are provided to child care services, schools, local community service centers (CLSCs), residential and long- term care ( nursing homes ) clinics and hospitals. In the institutional segment , it is imperative to control the quality of the environment since many individuals come together in a context of proximity; this circumstantial combination makes the spread of viruses , bacteria and fungi more convincing . Typically, the sampling is carried out from the basement in the areas of water penetration to the highest ventilation ducts of the building.


The sick building syndrome (SBS) (in English, sick building syndrome or SBS) really exists. We assess the air quality in office buildings, shopping centers, concert halls, museums, arenas, hotels, cinemas and theaters. We can help you track VOCs (volatile organic compounds), bacteria and fungi that afflict occupants. Mitigating problems related to poor air quality will increase the feeling of well-being of your employees, which promotes productivity and reduces absenteeism. Carbon dioxide (CO2), if the occupants complain of a lack of ventilation, "lack of oxygen", a musty smell and symptoms such as headaches and fatigue that can signal the existence of a problem. Concentrations of carbon dioxide are normally highest in late morning and late afternoon and vary with occupancy during the day. Moreover, the outside air is usually minimal at the height of the heating and cooling season.

The most common signs of contaminants inside the house are manifested by recurrent following symptoms: irritation of nose, throat and eyes, headache, nausea, immune system deficiencies, fatigue , runny nose, sneezing, difficulty breathing, chest pain, cough, sinusitis, rhinitis, alveolitis, bronchitis, asthma, pneumonia, ear infections, injuries, skin allergies, skin irritation, dermatitis, fever or chills. These toxic effects are due to various substances produced by fungi: propagules or spores for reproduction of the fungus, mycotoxins or chemicals associated with spores and volatile chemicals or their vapors detected musty odor. Make assess the presence of contaminants inside the home to alleviate your concerns. We will investigate to identify the source of chemical or biological odor, invisible contaminants visible mold and suspicious nature spots. Only results of the analyzes performed in the laboratory lead you to information that will enable you to know the real situation in which you are facing.


VOC / HAP: The presence in too high a concentration of VOCs and PAHs in the workplace can lead to lower performance and personnel performance. These sources of discomfort have a direct impact on absenteeism (impact on the entire production chain). Volatile organic compounds (VOCs) have a direct impact on health. Several air quality standards have been established to protect humans against the various pollutants that may adversely affect their health. The most common symptoms are headaches, skin irritations and breathing difficulties. One of the reasons that led to the classification of volatile aromatic hydrocarbons (PAHs) in the list of priority pollutants of the Environmental Protection Agency (EPA) is the toxic nature of some of them. They are biologically active molecules which, when absorbed by organisms, are amenable to transformation reactions under the action of enzymes leading to the formation of epoxide or hydroxyl derivatives ... PAH can also cause a decrease in the response of the immune system, increasing the risk of infection.

Organic contaminants: The Environmental control is a real challenge , particularly for food, pharmaceutical and cosmetics , which are required to produce products free of pathogens. A contaminant -free environment to slow the growth of undesirable microorganisms; therefore , the need to carefully control the production of a potential source of environmental contamination is essential . Inorganic contaminants: the environmental control is a must , especially for the aerospace industry , aerospace , electronics and nanotechnology , which are required to produce dust -free products . A dust-free environment helps to maintain the quality standards required for these types of production.



Quebec and nosocomial infections *

In Quebec health institutions, it is estimated that between 80 000 and 90 000 people suffer from a nosocomial infection, corresponding to 10% of admissions. Several studies have shown that it is possible to reduce by almost a third the number of new cases by implementing a well-structured program. For many years, health professionals, including infectious disease microbiologists and nurses on prevention and infection control, time and energy to this activity in institutions of the health network, where begins the fight against these infections, there where the primary responsibility for prevention and control of these infections. The hospital is a place where every day will find a large number of people to receive health care. These people may be more vulnerable to infections or, themselves be carriers of a transmissible infection.

Here as elsewhere , experience has taught us that many procedures and interventions in health care and the absence of some measures are likely to favor the transmission of infections . The ways may lead to higher infection levels than would be expected. This is why so many modes of intervention and procedures that the occurrence of nosocomial infections , that is to say, infections acquired in health care settings , must be constantly monitored .

A health service is a middle of the complex interactions between the patient , interventions he has sustained and the hospital environment . The physical condition and the patient's microbial flora , the treatment given and instrumentation used for care are all factors that affect the risk of acquiring and transmitting infection. Although this is an inevitable phenomenon , current knowledge does not allow to glimpse its eradication , the sound management of this risk in a perspective of quality of care should be referred .

Whatever order or level of government , we are able to offer a service that meets your expectations. The buildings in the public service, as stadiums and museums, are part of sectors where we are active. We offer the public a range of services that meet the highest standards , meeting the specific requirements of each.


Excellent quality of indoor air quality (IAQ) is essential to maintain good health. In North America, people spend the majority of their time indoors, whether for work, family life at home or in the context of the practice of leisure. Often these same people do not realize that health problems can be caused by too much exposure to indoor air of poor quality. In this context, children are more vulnerable than adults, and it should be noted that this could have serious implications on their respiratory system. Exposure to respiratory allergens in infancy greatly increases the risk of suffering from health problems in later life. In addition, children are often exposed to various contaminants inside the houses come mainly from the building components of human activity and domestic combustion appliances.

The most common chronic disease among children is asthma , the latter is constantly increasing and can be attributed to poor indoor air quality . For cons , by asking a few simple actions can significantly reduce respiratory diseases in children. One in ten children is allergic to pets and this increases to one in two children (50%) in asthmatics . In this context , it appears evident that children with such allergies should not be exposed to pets because the allergens found in the epidermis, in hair, saliva and urine of cats and dogs cause or exacerbate respiratory allergies .
