The ecological awareness variables were subdivided into three aspects: ecological knowledge, ecological emotion, and ecological...

Urban household waste causes serious pollution of the urban ecological environment. Waste separation and processing is an effective approach to reduce the ecological environment damage caused by household waste. From the perspective of the source of urban household waste separation, this paper...

With the increasingly prominent problem of agricultural non-point source pollution, the process of Rural Revitalization Strategy has been seriously affected. Studying the relationship between rural human capital and agricultural non-point source pollution is helpful to form talent bonus, improve...

With the emphasis on environment and health, the environmental protection, quality and safety of historical building’s fire-retardant coating has gradually become the focus of attention. There are a lot of volatile substances in the fire-retardant coating, which volatilize continuously for a long...

Time series analysis is a very effective method to analyze the dynamic characteristics of soil moisture at long-term scale. In this study, we have used the time series to analyze the relationship between precipitation and soil moisture on fixed dune at different soil depths (from 0 to 120 cm) during...

The resource environment loss has been evaluated using energy value and monetary value adopting complex ecological system analysis framework, Odum’s eco-econo mic system energy theory, and energy value analysis. The total amount of green ecological economy of Shenyang city from 2007 to 2016 was...

Aiming at the problems existing in the traditional monitoring system for logistics protection and transportation of solid waste, the optimization design of logistics protection and transportation monitoring system is realized by using big data analysis technology from two aspects of hardware and...

The evaluation of wetland ecosystem service lays the foundation to the wetland protection and exploitation. Evaluating the ecological service of all types of wetlands scientifically and reasonably is critical to improving the quality of ecological environment and securing the regional ecological...

Microbial kinetics of a hybrid upflow anaerobic sludge blanket (UASB) reactor were investigated when treating chemical synthesis–based pharmaceutical wastewater. Monod, Grau first-order, Grau second-order, Stover-Kincannon, Chen & Hashimoto kinetic models were applied to the hybrid reactor. The...

We utilized satellite and GIS technologies to address the relationship between urban land uses and Noise Pollution (NP) in one of the most crowded regions of Tehran city. Leq was determined in 170 stations of the studied area and an acoustic map was created. Moreover, using satellite remote sensing...

Untreated wastewater can have important effects on the environment and human. The aim of the work was to evaluate the effectiveness of modified barley straw to remove malachite green from industrial wastewater. Studied variables were pH, contact time, initial malachite green concentration, and...

The long start-up time and high demand of anaerobic ammonium oxidation (anammox) limit the practical applications of the anammox process. In this study, granular sludge supported on activated carbon (AC) was used as seed sludge. The start-up time of the reactor was substantially shortened, and the...

Abstract: Water is the main factor of movement and transport of pesticides and contamination of water by these pollutants is one of the most important challenges due to their widespread use and increased concentrations. Moreover, these compounds are on the U.S.EPA Priority Pollutant list because of...

Two hydrological climate modelling techniques, general circulation model (GCM) and hypothetical climate change scenarios, were used to analyse the hydrological response to the anticipated climate change scenarios in the Subarnarekha river basin in Eastern India. Both models verified individually for...

Volatile Organic Compounds (VOCs) are toxic for the environment and human health and their tendency to readily volatilize in the atmosphere can lead to problems connected to odours annoyance. Conventional VOCs gaseous emissions treatments entail the application of chemical-physical processes, only...

According to the data from Luzhou environmental monitoring center from 2015 to 2018, the tendency of spatial-temporal and ion characteristics in precipitation have been analyzed in order to demonstrate the precipitation pollution status. Traditionally, the environment may become worse as the...
