Abstract Municipal sewage sludge (MSS) and other biosolids are of high interest for agriculture. These nutrient-rich organic materials can potentially serve as organic fertilizers. Besides an increase of organic matter in soil, other positive effects were shown after their application. Especially the positive influence on circular economy increased the attention paid to management of MSS in recent years. Unfortunately, the use of sewage sludge has some drawbacks. Biosolids are frequently polluted with heavy metals, xenobiotic organic compounds and in-dustrial chemicals, which may be hazardous for the environment and humans. Here, we investigated the in-fluence of stabilization method and the size of wastewater treatment plant on the structure of microbial communities as well as the abundance of antibiotic resistance genes (ARG) and mobile genetic elements (MGE). All tested ARG and MGE were detectable in almost all of the samples. Interestingly, the presence of MGE as well as particular heavy metals correlated positively with the presence of several ARG. We conclude that the distri-bution of ARG and MGE in biosolids originated from municipal wastewater treatment plants, cannot be explained by the size of the facility or the applied stabilization method. Moreover, we postulate that the presence of pollutants and long-term impacts should be assessed prior to a possible use of sewage sludge as fertilizer.
