Background: The prevalence of asthma has increased in recent decades. Among the reasons for this increase is environmental pollution. Pollutants cause bronchial inflammation and introduce modifications in the pollen, making it more allergenic. Objective: Assess symptoms and medication requirements ...

In this paper, numerical modeling of the movement and dispersion of pollutant emissions between houses as well as the effect of a continuous barrier on the spread of pollutants was considered. To solve this problem, a system of Reynolds-averaged Navier-Stokes equations was used, and various...

There has been growing concern about the toxic effects of pollutants in the aquatic environment. In this study, a novel cell-based electrochemical sensor was developed to detect the toxicity of contaminants in water samples. A screen-printed carbon electrode, which was low-cost, energy-efficient,...

Particulate matter with an aerodynamic equivalent dimeter less than 2.5 μm (PM_2.5) and ozone (O₃) are major air pollutants, with coupled and complex relationships. The control of both PM_2.5 and O₃ pollution requires the identification of their common influencing factors, which has rarely been...

Despite wide adoption of pollution control technologies, industrial facilities emit about half the criteria air pollutants in the U.S. and contribute to poor air quality in many regions. Vegetation such as trees, shrubs, and grasses also have the capacity to directly remove air pollution. This work ...

In order to investigate rainfall runoff pollution level and effluent characteristics of different underlying surfaces in urban community, three kinds of underlying surfaces, such as road, roof and grass land at a cultural and educational area in Xi'an, Shaanxi province were selected as sampling...

Bioretention systems have been implemented as stormwater best management practices (BMPs) worldwide to treat non-point sources pollution. Due to insufficient research, the design guidelines for bioretention systems in tropical countries are modeled after those of temperate countries. However,...

Fertile and healthy soil is a productive, environment-forming, bioresource ecosystem of the Earth. Soil health can be considered an integral part of fertility, the most important functional biological category. The purpose of these studies was to study the effect of organic backgrounds with plowing ...

This study focused on the effects of external conditions on the performance of grass swales installed to improve stormwater runoff quality. Four grass swales in Beijing and Shenzhen with different underlying surface characteristics, antecedent dry weather period (ADWP), transport within the grass...

The objective of this study was to evaluate the influence of stoloniferous and fasciculated root systems, of Tifton 85 and vetiver grass respectively, on pollutant removal for primary treatment of sewage in horizontal subsurface flow constructed wetlands (HSSF-CWs). For this, three HSSF-CWs...
