Homes or commercial buildings used for the illegal cultivation of cannabis suffer severe mold damage.

Cannabis crops vary in size and service life , the extent of damage is extremely different from one place to another, and it is difficult to properly assess the decontamination requirements. In addition, contamination , even significant , is not always visible to the naked eye . We must therefore remember that indoor fungal contamination , even hidden , can make occupants sick. AES Environment, through a thorough, is able to assess the situation and provide a comprehensive plan remediation and rehabilitation of places where we held indoor cannabis growing operations .

In most cases , the adverse nature of fungal contaminants ( pathogens, irritating , toxic and / or allergens) that are found on the premises where it has cultivated cannabis are Aspergillus , Chaetomium and Stachybotrys ; they have great potential to make unhealthy hosts, sometimes even seriously ill .

ASPERGILLUS : Aspergillus is an opportunistic pathogen counting twenty species of which the most common Aspergillus fumigatus are, Aspergillus flavus and Aspergillus Niger. This is particularly problematic for people with fragile upper respiratory or suffer from diseases such as asthma and emphysema. Aspergillus fumigatus is the important pathogen for humans and is the most common cause of all forms of aspergillosis. While Aspergillus flavus is the second largest manager of human infections and is often associated with invasive aspergillosis in immunocompromised patients; particularly observed in paranasal sinus infections. With its white color that turns yellow and black conidia Aspergillus Niger is one of the most common species and most recognizable of the Aspergillus genus. It is the third most common species associated with invasive pulmonary aspergillosis. It is also often the cause of aspergilloma and is the agent as encountered in the case of otomycoses.

CHAETOMIUM : Chaetomium is a cosmopolitan fungal contaminant that can be found in soil or organic material in decomposition, but it is found especially on wood or gypsum paper. He is a frequent agent of onychomycosis, or skin, or brain infections in humans. Confirmed cases of human infections in Chaetomium are however few. The Chaetomium are part of a group of fungi that cause infections often referred to as phaeohyphomycoses or hyalohyphomycoses. Brain abscesses, peritonitis and skin lesions and subcutaneous may develop. Onychomycosis, both feet as hands can be exceptionally caused by species of Chaetomium in people whose immunity is normal. However, the full range of fungal infections in Chaetomium, including onychomycosis, sinusitis, empyema, pneumonia and disseminated fatal brain infection is revealed in immunocompromised hosts. Several papers reporting cases of infections where Chaetomium are identified as opportunistic infectious agents. In a case review, globosum Chatomnium was the species most commonly isolated in a group of nine clinical infections in Chaetomium. The diagnosis of pulmonary fungal infections is difficult in the absence of a culture confirmation; it seems that cases of infections Chaetomium have been falsely attributed to Aspergillus as some diagnoses were based on clinical symptoms and histopathological examinations.

STACHYBOTRYS : Stachybotrys fungal contaminant is found predominantly in indoor environments. (His favorite surfaces are paper, wood and cellulose compounds.) This fungus is known to cause mortality in farm animals after they have ingested contaminated feed. In humans, it is believed that this fungus could be involved in cases of poisoning as a result of inhalation or skin absorption of the toxins it produces. Since Stachybotrys spores are airborne rarely, it happens more often that they be identified by direct sampling from a contaminated area by swabbing or levy on tape by an air sampling. Stachybotrys interested healthcare professionals for several reasons; in particular, note its possible role in disease unhealthy buildings since this fungus infects the buildings plagued with design problems of mechanical systems or building problems, or buildings whose inadequate operational strategy leads to Chronic excessive moisture problems. Stachybotrys chartarum the subject of numerous scientific studies because of its potential role in the health problems associated with poor air quality of buildings contaminated with mold. These health problems are attributable to the powerful mycotoxins produced by some strains of S. chartarum.


Chemical pollutants are gases , nanoparticles or microparticles from combustion appliances , tobacco smoke, household products and personal care , and various building materials and furniture that can contain large amounts of organic compounds volatile .
