However, it is still unclear how As-transforming functional bacteria and dominant bacteria in the rhizosphere of P. vittata affect the microbial properties of crop rhizosphere soil, as well as how As concentration and speciation change in crop rhizosphere soil under intercropping. This is of great significance for understanding the biogeochemical cycle of As in soil and crops. This study aimed to use high-throughput sequencing and quantitative polymerase chain reaction (qPCR) to analyze the effects of different rhizosphere isolation patterns on the bacterial diversity and the copy number of As-transforming functional genes in pomegranate (Punica granatum L.) rhizosphere soil. The results showed that the abundance of bacteria in the rhizosphere soil of pomegranate increased by 16.3 %, and the soil bacter As-contaminated soil in the intercropping of As-hyperaccumulator and cash crops.The purpose of this study is to analyze the effect of economic growth, trade openness, urbanization, foreign direct investment, renewable energy consumption and natural resource rents on the ecological footprint in 31 Organisation for Economic Co-operation and Development (OECD) countries. Moreover, we examine the validity of Environmental Kuznets Curve hypothesis for the period from 1995 to 2017 by employing the second-generation panel data methodologies which allow to crosssectional dependence among countries. Our findings show that the inverted U-shaped Environmental Kuznets Curve hypothesis is valid in OECD countries. In line with the long-term model results, while URB and GDP increase EF, other variables decrease it. According to the causality test results, there is a bidirectional causality among ecological footprint, economic
