Antibiotic concentration levels were analyzed using the HPLC-MS/MS, heavy metal concentration level were measured by HGAAS and ICP-OES, while the integrase genes and ARGs were quantified using Real-Time PCR (qPCR) method. Manure, soil, and crops samples contained the highest concentration of Zn (104-105 ng gdm-1) and Cu (103-105 ng gdm-1) of all HMs tested. Manure-supplemented soil was characterised by a high concentration of doxycycline and enrofloxacin. A high abundance of integrase genes was noted in samples of manure (109-1010 copies gdm-1) and soil (107-108 copies gdm-1). Among all the analyzed genes, sul1, sul2, blaTEM, and integrase genes were the most common. Results of the study demonstrate the selective character of ARGs transfer from poultry and bovine manure to plants. The only gene to occur in all studied environmental compartments was sul1 (from 102 - groundwater to 1011 - poultry manure). It was also found that animal manure may cause an increase in the HMs concentration in soil and their accumulation in crops, which may influence the health of humans and animals consuming crops grown on manure-amended soil. The high abundance of integrase genes and ARGs and their reciprocal correlations with HMs pose a serious risk of the rapid spread of antibiotic resistance in the environment. Moreover, unusual dependencies between integrase genes and selected ARGs indicate the possibility of changes in the mobility nature of genetic elements.Glyphosate is a broad-spectrum herbicide that impairs testosterone synthesis in mammals. Leydig cells (LCs), the primary producers of testosterone, demonstrate rhythmic expression of c
