Abstract

Abstract

In order to evaluate the water purification capacities of household activated carbon drinking water purifiers and the behavioral characteristics of antibiotic resistance genes(ARGs), six kinds of household activated carbon water purifiers with different filter structures were purchased in this study. The dynamic changes of conventional water quality indicators and ARGs were tracked for 80 days. The research results showed that activated carbon drinking water purifiers could effectively remove residual chlorine for a long period of time. The removal effect of organic matter deteriorated with time. The physical properties of activated carbon had a great impact on water purification performance. Large specific surface area helped to remove organics. Five ARGs were quantitatively analyzed by qPCR, and the absolute abundances of sul1 and tetA were the highest. The absolute abundances of ARGs in the filtered water gradually increased with time, and reached a high level in 48~80 days in general. Sintered activated carbon with rigid pores and gradually-tight filter structure could play a certain control effect on ARGs. Organic matter and intI1 in water played an important role in the proliferation and transmission of ARGs.
