The rise of emerging pollutants in the current environment and requirements of trace
analysis in complex substrates pose challenges to modern analytical techniques. Ion …

Arsenic pollution in paddy fields has become a public concern by seriously threatening rice
growth, food security and human health. In this review, we delve into the biogeochemical …

Arsenic (As) is a major environmental pollutant and poses a significant health risk to humans
through rice consumption. Elevating the soil redox potential (Eh) has been shown to reduce …

The sharp redox gradient at soil-water interfaces (SWI) plays a key role in controlling arsenic
(As) translocation and transformation in paddy soils. When Eh drops, As is released to …

The heterogeneity of arsenic (As) and cadmium (Cd) in paddy soils seriously hinders the
assessment of contamination status and prediction of rice uptake. Their vertical patterns …

The environmental behavior of arsenic (As) has garnered significant attention due to its
hazardous nature. The fate of As often couples with sulfide, thus co-detecting arsenic and …

Arsenic (As) pollution in paddy fields is a major threat to rice safety. Existing As remediation
techniques are costly, require external chemical addition and degrade soil properties. Here …

Abstract Purpose Arsenic (As) and antimony (Sb) are toxic elements that usually co-occur in
paddy soils due to their chemical similarity. Those elements are redox-sensitive and shift …

Methane is the second most important greenhouse gas after carbon dioxide, and 8–11% is
emitted from paddy fields. Methanogenic microbial processes in water-saturated soils can …

Aims The biogeochemical cycles of elements from soils to plants are mainly governed by
their rhizosphere processes. Understanding these processes is challenging and remains …
