The density and distribution of bacteria indicative of pollution in the surface microlayer and subsurface water of the River Słupia were estimated. The number of heterotrophic bacteria, total coliforms, fecal coliforms and fecal streptococci were higher in the surface microlayer than in the underlying water. The average bacterial enrichment factor (EF) of the parameters studied in the bacterioneuston was 1.7 to 1.8 times higher than in bacterioplankton. During the annual study cycle, bacterial pollution indicators inhabiting the surface microlayer and subsurface water showed considerable monthly changes.
对斯卢皮亚河表层微层和次表层水中指示污染的细菌密度和分布进行了估算。表层微层中异养细菌、总大肠菌群、粪大肠菌群和粪链球菌的数量高于其下的水体。在细菌漂浮生物中所研究参数的平均细菌富集因子（EF）比浮游细菌中的高1.7至1.8倍。在年度研究周期内，栖息于表层微层和次表层水中的细菌污染指标呈现出显著的月度变化。
