A sequencing batch reactor was used to study long-term nitrogen removal performance of anaerobic ammonia oxidation bacteria (AnAOB) with trehalose addition treating nitrogen-rich saline wastewater. The operating temperature was controlled at 35 ± 0.5°C with influent pH of 7.5 ± 0.1. Trehalose played a significant role in enhancing long-term nitrogen removal performance. When trehalose was 0.1, 0.2, and 0.3 mM, ammonia removal efficiency (ARE) increased by 4.9%, 16.2%, and 32.4%, and nitrite removal efficiency (NRE) improved by 7.5%, 27.9%, and 42.2%, respectively. Optimal ARE and NRE were 92.4% and 97.4% achieved at 0.35 mM trehalose. Moreover, NO − 2 − N was removed completely within 2 hr at high trehalose content due to the synergistic effect resulting from AnAOB and heterotrophic denitrifying bacteria.The remodified Logistic model and modified Gompertz model were suitable for describing nitrogen removal in an operating cycle with trehalose addition. Fitted ARE max values were consistent with experimental values. Appropriate trehalose addition could shorten the response time of AnAOB coping with hazardous environment stress. Lag time was within 1 hr and the minimal fitted λ value got close to 0 achieved at 0.15 mM trehalose. • Practitioner points• Trehalose enhanced nitrogen removal of AnAOB in saline wastewater treatment.• Optimal ARE and NRE were 92.4% and 97.4% achieved at 0.35 mM trehalose. • Remodified Logistic and Gompertz models can analyze nitrogen removal with trehalose. • Appropriate trehalose can shorten response time of AnAOB coping with salt stress.

“…We collected data from the residents of four cities in China including Beijing, Shanghai, Qingdao, and Weifang. These cities were chosen because they had multiple communities that were going through environmental developments based on the homepage of the National Development and Reform Commission and reported to have some environmental issues (e.g., wetland loss and chemical pollution; Mi, Pan, Yu, & Wei, ; Pu & Fu, ; Wang et al, ; Yuan et al, ). The Commission listed Beijing, Shanghai, Qingdao, and Weifang as having 25, 3,437, 1,600, and 1,503 communities, respectively, under developments at the time of data collection.…”

This study drawing concepts from the fields of sociology, organizational behavior, and marketing examines residents' perceptions of justice in relation to environmental development. Although prior research raised issues related to environmental development from the justice perspective, very little is known about how residents perceive justice related to environmental development. Therefore, our study examines residents' perceptions of justice and how those perceptions influence the relationship with the government. More specifically, the study proposes that four types of justice (distributive, procedural, interpersonal, and informational) are related with the residents' trust in the government, which predicts their intentions to support for future projects and the government. To test the proposed model, we collected data from residents of four cities in China that were going through environmental development projects. The results of the study show perceptions of distributive justice and interpersonal justice have a significant positive effect on the residents' trust in the government and the environmental development. The study also finds that trust in the government and trust in the environmental development are positively related with residents' intentions to support the government and additional environmental developments. Our finding, however, does not support that either perceptions of procedural justice or perceptions of informational justice are important in the Chinese context. Implications of the study are presented. KEYWORDS environmental justice, social exchange theory, support intention, sustainable development, trust in the government

Access to geophysical data poses a challenge in Oceanography and Marine Sciences. Ocean databases are an efficient solution to storing, standardizing, validating, and sharing marine and environmental data. However, ocean databases of regional seas and coastal systems are still rare. In this article, we describe a regional ocean database for Jiaozhou Bay, a coastal system affected by increasing anthropogenic activities, such as land reclamation, a cross‐bay bridge construction, and land‐based pollutant discharges. Understanding the impact of human activities on Jiaozhou Bay requires a comprehensive range of research on biogeochemical and physical changes, and on the current environmental state of the bay. The Jiaozhou Bay database described here aims to inform this key research and also to serve as a reference for the future development of regional ocean databases. It includes three kinds of variables: on‐site, satellite, and modeling data. The database structure is unified and incorporates file names, header information (including metadata), measured values and data‐quality flags, which facilitate data exchange and use. We propose a system of data‐quality flags, based on 13 checks that encompass quality control of the different kinds of variables (e.g., satellite 2D data and on‐site profile data). Three examples, one for each type of data, illustrate the use and value of the Jiaozhou Bay database in better understanding the oceanographic characteristics of this bay and the impact of intensive anthropogenic activities on its marine environment.
