| Research Abstract |
I investigated the occurrence and fate of Antibiotic resistance genes (ARGs) in wastewater treatment plant(WWTP) by using next generation sequencer. WWTP influent, primary effluent, sedondary effluent, and final effluent were collected at WWTP A in Japan. As a result, 115 kinds of ARGs were detected in influent, which were reduced to 91 in secondary effluent. This result indicate that many kinds of ARGs are entered into WWTP, and some of them can be removed during biological treatment in WWTP. 95 kinds of ARGs were still detected in final effluent, which means ARGs may spread out from WWTP and enter into water environment. I also confirmed that kinds abd amount of ARGs were increased at downstream side of wastewater effluent in river basin. This result also indicates that ARGs may spread out from WWTP and enter into water environment.
