The use of settle plates (i.e., the sedimentation or depositional method) is not recommended when sampling air for fungal spores, because single spores can remain suspended in air indefinitely. 2010;73:2228. Impingement into liquids may also damage some microbial cells and affect viability and overlong sampling times may allow some cells to multiply in the liquid collection medium. Monitoring airborne microorganisms is therefore a key component of environmental monitoring in many sectors and a range of technological solutions has been developed to help operators achieve an effective monitoring programme, not just in the pharmaceutical sector, but in hospitals, food factories and a variety of other environments.
