The severe climate problem has forced the Chinese government to put forward the goal of "carbon peak" and "carbon neutrality", and the transportation industry is a key area of carbon emission reduction. Based on this background, this paper introduces the BCC model and the Malmquist-Luenberger index...

The growing Urbanization, Industrialization, Institutional, and IT sector development contribute to the exponential growth of motorized road transportation increasing the composition of harmful gaseous pollutants in ambient air. So, it is necessary to analyze and quantify the concentration of...

From this study, green seaweed Caulerpa Scalpelliformis is utilized as a sorbent for the removal of three metals such as lead (Pb), nickel (Ni) and zinc (Zn). Adsorption tests showed that maximum removal efficiency of 75.02% for Pb, 80% for Ni and 91.11% for Zn was obtained at an optimal equilibrium...

The total nitrogen (TN) is the key indicator for the eutrophication of Miyun Reservoir. Base on the long-term series of remote sensing, hydrological and water quality observation data, this paper comprehensively analyzed the trend of water quality especially the TN concentration and its influencing...

We used Vinyl-polyhedral oligosilsesquioxane (POSS)as a modified material and polyvinyl alcohol (PVA) to make a hybrid membrane for the pervaporation membrane separation of high-concentration caprolactam solution. The membranes were characterized by Fourier transform infrared spectroscopy, X-ray...

As an important resource for the IT sector and due to the extremely hazardous elements it contains and the low recycling rate, e-plastic waste management and recycling are growing swiftly. E-plastic waste utilization reduces aggregate costs, landfill costs and energy prices. Rapid population growth...

Toxic algal blooms have become a major environmental problem over the last few decades because of their impact on fisheries, leisure activities, national income and human health. It is known that Harmful Algal Blooms (HABs) can occur naturally but the frequency of occurrence as well as their...

Investigating the spatiotemporal characteristics and factors of urban carbon emissions is essential to reduce carbon emissions and achieve dual carbon goals. In this study, we examined the change tendency of carbon emissions using the coefficient of variation, the Sen’s slope method, and the Mann...

This study was carried out with the aim of using three processes of soil washing, electrofenton and biological leaching method in order to rehabilitate the soil contaminated with lead and phenanthrene around the south Tehran oil refinery. The variables examined in this study are the amount of soil...

Excessive consumption of natural resources for concrete production results in the diminution of conventional resources, leading to the scarcity of construction materials. Perhaps, the dumping of construction wastes increases the municipal wastes ensuing in disposal problems. The dumped construction...

Microplastics were discovered in soil samples taken from fields in Tamil Nadu, India's Ponneri, Redhills, and Thirumazhisai where the fields had been amended with compost made from biowaste. The soil sample taken from agricultural field in Ponneri had the highest microplastic level, which was...

Clean water and its requirement are one of the emerging needs in recent days. Water pollution creates more amount of toxic nature to the clean water and it increases the accumulation of poisonous contaminants in the water sources. Heavy metal ions are the type of toxic pollutant released from...

The goal of this work is to evaluate generation estimation and metals recycling potential of retired mobile phones in Philippines. The generation estimation is conducted with the sales&new method and statistic data, such as sales of mobile phones and amount of the subscribers. The result shows that...

In this study, an attempt is made to understand the effectiveness on initial treatment of coconut shell on the strength of concrete. The coconut shell materials obtained from the agricultural wastes are used as a replacement for coarse aggregate in conventional concrete. From the particle size...

Every year, the number of people who die because of pollution rises, with air pollution being the major cause. Air pollution is generated by a variety of factors, one of which is pollution caused by automobiles. Technological improvements make great efforts to detect accidents and monitor the...

Municipal solid waste [MSW] has gained prominence in recent years as the rate of its generation has increased significantly. The serious problem of MSW management exists in almost all regions of India. This study aims to generate energy from MSW by selecting a suitable MSWM technology with the help...

Air pollution monitoring is becoming increasingly important, with an emphasis on the effects on human health. Because nitrogen dioxide (NO2) and sulphur dioxide (SO2) are the principal pollutants, many models for forecasting their potential harm have been created. Nonetheless, making precise...

In this study, neem leaf biosorbent, prepared through chemical synthesis and activated with concentrated sulfuric acid, was utilized as an organic adsorbent for the removal of heavy metal ions, specifically arsenic (As) and chromium (Cr), from wastewater. The characteristics of the biosorbent were...

Methyldimethylhydrazine and its by-products cause serious damage to human health. In this paper, Re3+-doped mesoporous TiO2 were synthesized for the photodegradation of UDMH. The structure, morphology and optical properties of photocatalyst were extensively characterized. The photocatalytic...

By using a hybrid solar mineral water production setup to turn sea water into mineral water, this research intends to provide a comprehensive solution to the human need for drinking water. Before feeding seawater into the solar still, it also applies the proper pretreatment. In order to increase the...
