Plastic litter is widely acknowledged as a global environmental threat, and poor
management and disposal lead to increasing levels in the environment. Of recent concern is …

This critical review presents the key factors that control the occurrence of natural elements
from the uranium-and thorium-decay series, also known as naturally occurring radioactive …

The transport of ferrihydrite colloid (FHC) through porous media is influenced by anions (eg,
PO43–) and cations (eg, Ca2+) in the aqueous environment. This study investigated the …

Biochar colloids' association with heavy metal needs be studied to precisely evaluate the
effectiveness of biochar as sorbents. The structure of biochar colloids and their roles in …

Although minor in abundance in Earth's crust (U, 2–4 ppm; Th, 10–15 ppm) and in seawater
(U, 0.003 ppm; Th, 0.0007 ppm), light actinides (Th, Pa, U, Np, Pu, Am, and Cm) are …

The groundwater table fluctuation (GTF) zone is an important medium for the hydrologic
cycle between unsaturated soil and saturated aquifers, which accelerates the migration …

The manufacture and multiple uses of zinc oxide (ZnO) nanoparticles (NPs) will represent a
possible source of soil contamination. Little is known about how these NPs transport in soil …

This study aims to gain insights into the interaction of virus particles with clay colloids.
Bacteriophages MS2 and ΦX174 were used as model viruses and kaolinite (KGa-1b) and …

Soil and groundwater contamination has always been a global concern. Contaminants are
migrated and transformed in the soil and groundwater environments, which in turn pose …

Fractured rock aquifers are susceptible to contamination, with metal (loid) s rapidly migrating
from poorly developed overburden to the fractured rock vadose zone and thus into …
