In the context of artificial groundwater recharge, a reactive soil column at pilot-scale (4.5 m depth and 3 m in diameter) fed by treated wastewater was designed to evaluate soil filtration ability. Here, as a part of this project, the impact of treated wastewater filtration on soil bacterial communities and the soil's biological ability for wastewater treatment as well as the relevance of the use of multi-bioindicators were studied as a function of depth and time. Biomass; bacterial 16S rRNA gene diversity fingerprints; potential nitrifying, denitrifying, and sulfate-reducing activities; and functional gene (amo, nir, nar, and dsr) detection were analyzed to highlight the real and potential microbial activity and diversity within the soil column. These bioindicators show that topsoil (0 to 20 cm depth) was the more active and the more impacted by treated wastewater filtration. Nitrification was the main activity in the pilot. No sulfate-reducing activity or dsr genes were detected during the first 6 months of wastewater application. Denitrification was also absent, but genes of denitrifying bacteria were detected, suggesting that the denitrifying process may occur rapidly if adequate chemical conditions are favored within the soil column. Results also underline that a dry period (20 days without any wastewater supply) significantly impacted soil bacterial diversity, leading to a decrease of enzyme activities and biomass. Finally, our work shows that treated wastewater filtration leads to a modification of the bacterial genetic and functional structures in topsoil.

Green consumption has drawn attention from various sectors of society recently. However, the "mismatch" of awareness and behavior remains despite consumers' heightened environment-friendly awareness. Based on the theory of emotional cognition and cognitive dissonance, This study examined the impact of consumers' expected guilt on green consumption intentions, and also introduced consumer cognitive utility to further uncover the mechanism in the process of influence by a survey of young Chinese people born after the 80s. Path analysis and hypothesis verification using AMOS showed that consumers' expected guilt not only directly affects the intention of green consumption, but also indirectly affects the intention of green consumption through the intermediation of cognitive utility.
