Potential Heavy Metals Pollution Contribution from Wash-Off of Urban Road-Dust

open access: yesToxics, 2022
Based on the different particle sizes of street dust, the potential pollution load of heavy metals from dry and wet atmospheric deposition to surface runoff in different functional areas of Zhengzhou city was estimated by using the rain-scour heavy metal

Diffusion of reacting pollutants

open access: yesApplied Mathematical Modelling, 1980
Abstract The Boltzmann equation including reactive scattering terms is the correct description of the combined transport-reaction process. A suitable parameterization transforms it into a set of differential equations governing the macroscopic mass balance.

Diffuse Pollution and the Role of Agriculture [PDF]

open access: green, 2003
Agriculture contributes negative and positive externalities to society, that is, beneficial and detrimental changes in human wellbeing to third parties for which they are not generally compensated or charged. Beneficial externalities include the creation of amenity and landscape and negative externalities include pollution of surface and groundwater ...

Effects of the Fluid Replacement Method During Online Hemodiafiltration on the Solute Removal Performance and Biocompatibility Using the Asymmetric Cellulose Triacetate Membrane

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.
