The predominant microorganisms in samples taken from shower heads in residences in the Korean city "N" were Stenotrophomonas maltophilia, Sphingomonas paucimobilis, Acidovorax temperans, and Microbacterium lacticum. Legionella was not detected in this case. The volatile organic compounds (VOCs) vinylacetate, NN-DMA, cis-1,2-dichloroethylene, epichlorohydrin, and styrene were measured in five types of plastic pipes: PVC, PB, PP, PE, and cPVC. The rate of multiplication of the heterotrophic plate count (HPC) attached on the copper pipe in contact with hot tap water was higher than the rate for the copper pipe in contact with cold tap water. Biofilm accumulation on stainless steel pipes with added acetate (3 mg/L) was 2.56 times higher than the non-supplemented condition. Therefore, the growth of HPC in the pipe system was affected by the type and availability of nutrients and depended on variables such as heating during the hot water supply.
从韩国城市“N”的住宅淋浴喷头中采集的样本中，主要的微生物是嗜麦芽寡养单胞菌、少动鞘氨醇单胞菌、温和食酸菌和乳酸微球菌。在这种情况下没有检测到军团菌。在五种类型的塑料管中测量了挥发性有机化合物（VOCs）醋酸乙烯酯、NN-DMA、顺-1,2-二氯乙烯、环氧氯丙烷和苯乙烯：聚氯乙烯（PVC）、聚丁烯（PB）、聚丙烯（PP）、聚乙烯（PE）和氯化聚氯乙烯（cPVC）。与热水接触的铜管上附着的异养平板计数（HPC）的繁殖速度高于与冷水接触的铜管。在添加醋酸盐（3 毫克/升）的不锈钢管上生物膜的积累比未添加的情况下高 2.56 倍。因此，管系统中 HPC 的生长受到营养物质的类型和可用性的影响，并取决于热水供应期间的加热等变量。
