Answer 2

WWTPs are a significant point source for AMRDs and antimicrobials. WWTPs are relatively nutrient-rich, heavily contaminated environments that receive waste from a variety of AMRD-loaded environments, including hospitals, industrial and agricultural sites and release both solid and liquid by-products that can disseminate AMRDs. Influent can be contaminated with a variety of pollutants, including antimicrobial agents, pharmaceuticals, personal care products, and heavy metals, which can accumulate within WWTPs. Many microbial and chemical contaminants in wastewater cannot be degraded by the treatment process or inactivated through disinfection of the effluent. For those contaminants that can be degraded, the resulting metabolites may still have antimicrobial or selective activity. WWTP effluent and solid waste products not only have a high prevalence of AMRDs but also release selective agents into the receiving environments
