dc.description.abstract | Purpose Sewage sludge land application is strongly recommended to improve soil quality and fertility despite the presence
of pollutants, pathogens and antibiotic resistance genes. This study aimed to assess the fertilization value of low and recommended
by law sewage sludge dose (15 t ha−
1).
Materials and methods In a 540-day field study, the effect of sewage sludge on the soil physicochemical and microbial
parameters, emphasising antibiotic and metal resistance spread, was investigated.
Results In contrast to expectations, sewage sludge did not improve the organic matter, nutrient content and microbial activity
in the soil; therefore, the fertilization effect was not achieved. Moreover, an increase in the bioavailable Cd, Ni and Cu
content was observed. Canonical correspondence analysis revealed that these increases mainly explain the changes in the
soil microbial community. Sixteen resistance genes and four integron classes were detected in both the total DNA and on
plasmids isolated from sewage sludge. Obtained plasmids confer β-lactam resistance or extreme resistance to tetracycline
(> 256 μg mL−
1). Two antibiotic resistance genes (blaNPS-2, tetA) were transferred into the fertilized soil and detected up to
6 months after the fertilization.
Conclusion Our results provide evidence that the regulated dose of sewage sludge, even when characterized by low total
metal content, may affect soil microbial microbiome and resistome. Therefore, these findings provide critical data that have
public health implications, which may raise concerns about the suitability of applying sewage sludge to the soil even at the
low regulated dose. | pl_PL |
