Wet-chemical extraction of soil is a standard procedure to characterise pedogenic
aluminium (Al) and iron (Fe) species, especially oxides, allophanic minerals and metal …

Dietary deficiency of selenium is a global health threat related to low selenium
concentrations in crops. Despite the chemical similarity of selenium to the two more …

Linkages between soil structure and physical–chemical soil properties are still poorly
understood due to the wide size-range at which aggregation occurs and the variety of …

In redox-affected soil environments, electron transfer between aqueous Fe (II) and solid-
phase Fe (III) catalyzes mineral transformation and recrystallization processes. While these …

Arsenic is a metalloid with a high risk of carcinogenesis. High levels of arsenic in the water
and soil environment can directly impact on humans and ecosystems. Ferrihydrite plays an …

Background Knowledge of soil aggregate formation and stability is essential, as this is
important for maintaining soil functions. Aims This study aimed to investigate the influence of …

The association of arsenic (As) with colloidal particles could facilitate its transport to adjacent
water systems or alter its availability in soil–rice systems. However, little is known about the …

Naturally-occurring colloids and nanoparticles are crucial in transporting heavy metal
contaminants in soil-water systems. However, information on particle-bound metals' size …
