Groundwater contamination risk assessment is a useful tool for groundwater pollution prevention and control. Previous study has evaluated groundwater contamination risk at Yinchuan Plain, China, according to aquifer vulnerability. The present study enriches the assessment of contamination risk by...

Understanding the discharge characteristics of pollution sources and their differences in geographical space is an important basis for improving water pollution control level in basin scale. Discharge characteristic evaluation and cluster analysis of basic water pollutants in 60 cities in the...

Understanding pollutant transport process and source apportionment is critical to urban stormwater pollution mitigation. Previous studies have investigated transport and sources of road deposited sediments (RDS) and sewer sediments individually, and most of these studies focused on stormwater ...

The traditional Fenton process cannot efficiently remove organic pollutants because of the low recycling efficiency of Fe2+. Hydroxylamine (HA) is a typical reducing agent that can accelerate the Fe2+ cycle. Thus, the HA-facilitated Fe²⁺/H₂O₂ removal of tartrazine was investigated. Only 31.4%...

Background: Air pollutants are found associated with various health effects in chronic obstructive pulmonary patients. Given the complicate chemical components of air pollutants, it is not clear which components are the main risk factors for these health effects. Objectives Based on the COPD in...

The biogas slurry (BS) is a kind of residue liquid of biogas produced by anaerobic fermentation with livestock and poultry manure as the main raw materials. The biogas project in China began in the 1970s. With the development of livestock and poultry farming, and anaerobic digestion technology of...

Exposure to amorphous silica nanoparticles (SiNPs) has increased dramatically, and concerns are growing about their potential health effects. However, their long-term systemic toxicity profile and underlying mechanisms following respiratory exposure still remains unexplored. It is well documented...

Understanding the entire urban diffuse pollutant transport process in a Low Impact Development (LID) pilot catchment is critical for developing efficient and reliable LID strategies to remove stormwater pollutants. Previous studies focused on the LID performance at a system scale and modeling work. ...

Regenerated keratin-based adsorbents have attracted much attention in environmental pollution remediation. However, fabricating keratin-based adsorbents with excellent adsorption performance is still a challenging issue due to its weak mechanical property. In this study, mechanical robust keratin...

Indoor airborne microplastics fibers (MPFs) are emerging contaminants of growing concern. Nowadays, air conditioners (ACs) are widely used in indoor environments. However, little is known about their impact on the distribution of indoor MPFs. In this study, we first disclosed the prevalence of MPF...
