Deriving arsenic concentration guideline values for soil and irrigation water for rice cultivation (2023)
Thesis

Arsenic (As) is a naturally occurring, toxic trace element that can be found in irrigation water, soil, and crops. Rice accumulates higher concentrations of As in its grains than other cereals like wheat and barley. This leads to concern over dietary...
