Bioaerosols Assessment and Control
We use indoor air and surface sampling to help determine the level of biological particles present in your environment. These contaminants can cause irritation or adverse short or long term health problems . Tests can locate the sources of indoor microorganisms to facilitate effective remediation.
Agar Impaction Sampling
Culturable sampling is one of the most common methods of volumetric air analyses. The sampling device works by drawing a measured volume of air through an instrument that contains a petri dish containing a culture medium. Spores that impact onto the plate are then allowed to incubate and grow; after which the colonies may be counted and identified.
Non-culturable spore trap sampling
Non-culturable spore trap samplers draw measured volumes of air through a sampling device for a specified length of time. The collection surface is a sticky-coated glass slide. Particles in the air (spores, dust, etc.) impact onto the sticky surface and are "trapped" for later analysis.
Surface Swab Sampling
Surface samples can be taken by tape lift imprint, wiping the suspect surface with a special swab, or submitting a bulk sample of surface into a petri dish.
Air and surface sampling are used to identify biological agents and assist us in understanding the conditions that allow them to grow. It suggests possible pathways of propagation from the environmental source to the human occupants by understanding exposure-response and health effects relationships.
The success of any sampling method and its interpretation are dependant on the disciplined and methodical approach of the microbiologist. The speciation of the sampled microorganisms will identify the resident bacteria and fungi and indicate:
- Whether they are pathogenic and, if so, the possible health consequences
- The possible source of the micro organism reservoir/amplification point
- Whether they originated internally or from an external source
