Potassium is a macroelement essential to many aspects of plant life, such as
photosynthesis, phloem transport or cellular electrochemistry. Many enzymes in animals or …

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 …

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 …

Potassium isotopic compositions of profiles through saprolites developed on a diabase in
South Carolina, USA, and on a granite in Guangdong, China, allow characterization of the …

The causal effects among uplift, climate, and continental weathering cannot be fully
addressed using presently available geochemical proxies. However, stable potassium (K) …

Stable potassium isotopes are one of the emerging non-traditional isotope systems enabled
in recent years by the advance of Multi-Collector Inductively-Coupled-Plasma Mass …
