Spotlight on the vertical migration of aged microplastics in coastal waters

Author(s): Yang X; Huang G; Chen Z; Feng Q; An C; Lyu L; Bi H; Zhou S;

Coastal waters are complex and dynamic areas with unique environmental attributes that complicate the vertical migration of microplastics (MPs). The MPs that enter coastal waters from diverse sources, including terrestrial, riverine, oceanic, and shoreline inputs undergo various aging pathways. In this study, the variations in the physiochemical character ...

Prolonged drying impedes the detachment of microplastics in unsaturated substrate: Role of flow regimes

Author(s): Feng Q; Chen Z; Huang G; An C; Yang X; Wang Z;

The detachment of microplastics (MPs) from porous media under different moisture conditions and flow regimes has garnered limited attention within the research community. The present study investigates the detachment of MPs from porous media under wet and dry conditions combined with steady and transient flow. For both the wet and dry conditions, the incr ...

Unveiling the Vertical Migration of Microplastics with Suspended Particulate Matter in the Estuarine Environment: Roles of Salinity, Particle Properties, and Hydrodynamics

Author(s): Yang X; Huang G; Feng Q; An C; Zhou S; Bi H; Lyu L;

The estuary is an energetic area connecting the inland, river, and ocean. The migration of microplastics (MPs) in this highly complex area is tied to the entire ecosystem. In this study, the effects of cohesive SPM (clay) and noncohesive SPM (sand) on the vertical migration of positively buoyant MPs, polyethylene (PE), and negatively buoyant MPs, polytetr ...

Exploring the decentralized treatment of sulfamethoxazole-contained poultry wastewater through vertical-flow multi-soil-layering systems in rural communities.

Author(s): Song P, Huang G, An C, Xin X, Zhang P, Chen X, Ren S, Xu Z, Yang X

Sulfamethoxazole (SMX) is the most widely distributed sulfonamide antibiotics detected in decentralized poultry wastewater in rural communities. As an economically-feasible and eco-friendly technology for decentralized wastewater treatment in rural areas, vertical-flow multi-soil-layering (MSL) system was promising to mitigate the ecological and human hea ...

Exploration of nanocellulose washing agent for the green remediation of phenanthrene-contaminated soil.

Author(s): Yin J, Huang G, An C, Zhang P, Xin X, Feng R

Polycyclic aromatic hydrocarbons are hazardous contaminants existing ubiquitously in polluted soil. In this study, using nanocellulose (CNC) fluid as an eco-friendly agent was proposed for the first time in the remediation of phenanthrene (PHE) contaminated soil. The effects of environmental factors on the mobilization of PHE in soil by CNC nanofluid was ...

Removal of arsenic from water through ceramic filter modified by nano-CeO2: A cost-effective approach for remote areas.

Author(s): Yang X; Huang G; An C; Chen X; Shen J; Yin J; Song P; Xu Z; Li Y;

The groundwater with high arsenic concentration is widespread, especially in many remote areas of developing countries. Arsenic existing in drinking water sources has a high risk to human health. In this study, an innovative effort to remove As(V) from water using ceramic filters functionalized with CeO2 nanocomposites (CF-CeO2) was investigated. Consider ...

Comprehensive evaluation of adsorption performances of carbonaceous materials for sulfonamide antibiotics removal.

Author(s): Luo B, Huang G, Yao Y, An C, Li W, Zheng R, Zhao K

Sulfonamide antibiotics have highly toxic effects on humans and other organisms within the food chain. Adsorption by various carbonaceous materials is an effective method for removing them from the aqueous environment. Batch adsorption experiments were conducted between adsorbents and sulfamethoxazole (SMX) by studies of characterization, isotherm model, ...
