The authors fabricated and modified tungsten oxide micro and nanostructures, studied their electrochemical capacitance, and ran a preliminary test of their use as sensors for hazardous dyes in food. Tungsten here is an electrode material, not an analyte or contaminant.
Key numbers
This paper reports no numerical findings relevant to tungsten exposure.
Methods (brief)
Tungsten oxide structures were grown and modified, then examined by pulsed and cyclic voltammetry, electrochemical impedance spectroscopy and microscopy.
Evidence fitness
Off-topic for dietary exposure: an electrochemical sensor development paper that does not support dietary exposure or toxicity claims for tungsten.
Limitations
Preliminary sensing tests only; no tungsten release from electrodes or tungsten in foods was measured.
