This work critically reviews stable isotope fractionation of essential (B, Mg, K, Ca, Fe, Ni, Cu,
Zn, Mo), beneficial (Si), and non-essential (Cd, Tl) metals and metalloids in plants. The …

Potassium (K) is a crucial macronutrient for plants and is the predominant inorganic cation in
plants, constituting up to 10% of plant biomass on a dry weight basis and originating from …

Rainwater dissolves urban air contaminants that threaten sustainable urbanization and
human health. Tracing rainwater contamination supports urban management and …

This work presents the systematic investigation of K contents and stable K isotopic
compositions of surface waters, groundwater, wastewaters, suspended particles, bed …

Plants play a critical role in the surficial environment, influencing energy transfer, the global
carbon cycle, and climate change. Potassium (K) controls many essential plant physiological …

Excess and limited trace metal contents in soils and plants can limit crop yields and pose a
risk for the environment and human health. This mini-review reports on the emerging …

Potassium (K)-containing fertilizers are widely applied in agriculture to improve plant growth,
yet fertilizer overuse induce pollution of waters, calling for methods to trace the sources of K …

The naturally occurring stable isotopes of potassium (41K/39K, expressed as δ41K) have
the potential to make significant contributions to vertebrate and human biology. The utility of …

Stable potassium (K) isotopes (41K/39K) have shown great promise as novel chemical
tracers for a wide range of bio-, geo-, and cosmo-chemical processes, but high precision …

The controls on potassium (K) isotope fractionation during chemical weathering are
evaluated using two regolith profiles developed over∼ 350 kyr on the humid and arid sides …
