摘 要:
The environmental monitoring program does not have officially designated sampling tools, which will have different sampling factors that affect the results of microbial determination. First, determine whether different tool materials and sampling environments will affect the sampling results. The results show that the release efficiency and recovery efficiency of cotton swabs are the lowest, while the efficiencies of cellulose sponge and PU foam are significantly excellent. And, in the dry environment will significantly reduce the efficiency of the swab. In addition,
discuss whether different elution techniques will affect the sampling results. The results show that there is no significant difference was found between the machine stomacher and manual elution by human operator or between operators. Therefore, in conclusion, the type of swab and the surface condition will affect the efficiency of the swab. Choosing the appropriate type of swab for the surface condition will improve the efficiency of the swab and the effectiveness of the EMP.
