Abstract:
... The vertical distribution of air pollutants in urban street canyons is closely related to residents’ health. However, the vertical air quality in urban street canyons has rarely been assessed using field observations obtained throughout the year. Therefore, this study investigated the seasonal and annual concentrations of particulate matter (PM₂.₅ and PM₁₀), CO, NO₂, SO₂, O₃, air quality index, an ...

Abstract:
... Photooxidative removal of pharmaceuticals and organic dyes is an effective way to eliminate growing micropollutants. However, photooxidation often results in byproducts as secondary hazardous substances such as phytotoxins. Herein, we found that photooxidation of common antibiotic tetracycline hydrochloride (TCH) over a metal-free 8-hydroxyquinoline (8-HQ) functionalized carbon nitride (CN) photoc ...

Abstract:
... Organic-contaminated soils are a major health issue because pollutants can be transferred to waters, air, and living organisms. Many remediation technologies have been developed, yet single methods are usually not fully efficient due to the wide diversity of soil and pollutant properties. Therefore, combining several methods has recently shown wider application range, higher efficiency, and better ...
