Soil pollution has become a real threat to mankind in the 21st century. On the one hand, soil pollution has reduced the world's arable land area, resulting in the contradiction between the world's population expansion and the shortage of arable land. On the other hand, soil pollution has seriously...

During the latest several decades, the continuous development of the economy and industry has brought more and more serious organic pollutants to the natural environment, which have inevitably aroused severe menace to human health and the environmental system. The nano zero-valent iron (NZVI)...

This study applied the techniques of high-resolution dialysis (HR-Peeper) and diffusive gradients in thin films (DGT) to explore the effects and the behind mechanism for inhibition phosphorus (P) releasing from sediments by nFe₃O₄ capping. The highest decreasing rates of SRP and labile P (i.e., 49% ...

In response to climate change and energy conservation and emission reduction targets, the green development of transportation has become one of the most concerned topics in the world. Many studies have verified the impact of intra-city rail on environmental pollution, but little attention has been ...

Different prediction models have important effects on the accuracy of spatial distribution simulations of heavy metals in soil. This study proposes a model (RFOK) combining a random forest (RF) with ordinary kriging (OK), multi-source environmental data such as terrain elements, site environmental...

The limit of detection (LOD) was increased by preserving with methanol when collecting soil volatile organic compounds (VOCs), which may result in undetecting of higher levels of VOCs. Thus, it exerts the influence on the determination of site pollution risk. Firstly, the improvement range of LOD...

Increasing availability of data related to air quality from ground monitoring stations has provided the chance for data mining researchers to propose sophisticated models for predicting the concentrations of different air pollutants. In this paper, we proposed a hybrid model based on deep learning...

In order to select the atmospheric environment hotspot grids in Beijing-Tianjin-Hebei and its surrounding regions, the monthly haze days and mass concentrations of the PM_2.5, NO₂, SO₂ were retrieved using satellite observation. Based on the retrieved results of these four items, firstly, the...

Accurate estimation of pollutant emissions from household solid fuel combustion has been a challenging issue in developing regions, especially in the heavily polluted northern China region. Basing on a survey of residential household energy use in all villages in Beijing, this study developed a...

Background: The prevalence of childhood allergies has increased during past decades leading to serious hospitalization and heavy burden worldwide, yet the key factors responsible for the onset of early symptoms and development of diagnosed diseases are unclear. Objective: To explore the role of...
