Biological efficiency the relative efficiency of the sampler in collection of microorganisms on a surface or in a liquid so that they are viable and can be counted. SUBMITTED TO :- Here, the formula will be expressed as: The concentration of the contaminant will be expressed either in mg/m3 (for particulate matter) or in ppm (for the gaseous matter). Background: Since air can play a central role as a reservoir for microorganisms, in controlled environments such as operating theatres regular microbial monitoring is useful to measure air quality and identify critical situations. SUBMITTED BY :-DEEPAK RAVI Air pollution measurement , emission estimates, Water sampling , procedure, purpose , techniques and equipments. Methods: Air sampling of 10 OT's, 4 ICU's and 1 LR were done by settle plate method. Am. They are useful for qualitative analysis of airborne microorganisms and the data they produce may detect underlying trends in airborne contamination and provide early warning of problems. Tap here to review the details. 289 Settle plates have been used mainly to sample for particulates and bacteria either in research studies or during epidemiologic investigations. B.Sc. The https:// ensures that you are connecting to the The mean TVC at rest was 12.4 CFU/m3 and 722.5 CFU/m2/h for active and passive samplings respectively.
