The authors built a molecularly imprinted electrochemical sensor from a palladium, yttrium oxide and boron nitride composite to detect the herbicide glyphosate in drinking water. Yttrium oxide is part of the electrode; the analyte is glyphosate.
Key numbers
This paper reports no numerical findings relevant to yttrium exposure.
Methods (brief)
Composite synthesis by sonication and borohydride reduction, electropolymerization of an imprinted polypyrrole film, and voltammetric calibration and recovery tests.
Evidence fitness
Off-topic for dietary exposure: a herbicide sensor paper that does not support dietary exposure or toxicity claims for yttrium.
Limitations
No yttrium measurements in water or food.
