Experimental studies on the reaction of micro-organisms on fine-dust filters (type C) and high-efficiency particulate air filters (type R and S) have shown no evidence of a growth of microorganisms. Therefore efforts were aimed at detecting antimicrobial factors which were supposed to exist in the precipitated acidic continental aerosol. With this in mind, air filters from different locations and with service times were extracted in water and the extract was tested for its antimicrobial effects. Die-off rates are used to demonstrate the influence of such extracts with varying concentrations of substances and pH values on bacteria.
关于微生物在细尘过滤器（C型）和高效空气过滤器（R型和S型）上反应的实验研究表明，没有证据表明微生物会生长。因此，研究重点在于检测可能存在于沉淀的酸性大陆气溶胶中的抗菌因子。考虑到这一点，将来自不同地点且使用过不同时长的空气过滤器在水中进行萃取，并对萃取物的抗菌效果进行测试。死亡速率用于证明此类含有不同物质浓度和pH值的萃取物对细菌的影响。
